Abstract

( Research on species similarity and species diversity of small mammals in 10 repetitive sampling

occasions (500 trap nights) was conducted in two different habitats an open and closed habitat

The first sampling were carried out in Sarna Jaya Nature Reserve (SJNR) from April to

September 2008 and second sampling conducted in Kubah National Park (KNP) from February

to June 2009 Closed model was chosen where sampling was conducted for five consecutive trap

days in 10 repetitive sessions each session has about five days to one week rest A hundred of

cage traps were set up and placed in grid system at each study site respectively and markshy

recapture method were used to capture the small mammals l

Sarna Jaya Nature Reserve situated in Kuching Sarawak can be classified as geographically

closed habitat or an island habitat A total of 330 individuals of small mammals been trapped in

5000 trapnights consist of six species namely Calloscuirus notatus C prevostii borneensis

Sundamys muelleri Tupaia tana T minor and Rhinoscuirus lauticaudatlls from three families

(Tupaiidae Scuiridae and Muridae) and from two orders (Scandentia and Rodentia) Species

similarities of small mammals species composition on 10 repetitive sampling occasions from

SJNR were calculated and analysed Jaccard similarity coefficient and Sorensen similarity

coefficient indicated a value of 1 in seven tested sampling occasions (3 vs 4 3 vs 5 4 vs 5 3 vs

9 4 vs 9 5 vs 9 and 2 vs 10) Occasion 7 vs occasion 10 noted high values for Morisita-Hom

similarity coefficient (0991) and 0909 is the highest value for Bray-Curtis similarity coefficient

(occasion 9 vs occasion 10) The differences of value for four similarity coefficient indices may

he influenced by factors like sample size and abundance of most abundant species

v

Kubah National Park is classified as a geographically open habitat for this study A total of 98

small mammals were captured in a total of 5000 trapnights consisting of 10 species namely

Maxomys rajah M surifer M whiteheadi Leopoldamys sabanus Lariscus insignis

Sundascuirus lowi Tupaia tana T dorsalis T glis and Echinosorex gymnlllUs from four

families (Erinaceidae Scuiridae Tupaiidae and Muridae) of orders (Rodentia Scandentia and

Insectivora) Species similarity of small mammals in 10 repetitive sampling occasions showed

differences in term of similarity value for four similarity indices All similarity indices noted 0

value for three tested sampling occasions (1 vs 8 5 vs 8 and 8 vs 9) which indicates that there

are no shared species between two tested sampling occasions Occasion 9 vs occasion 10 noted

high value for Jaccard similarity coefficient (075) and Sorensen similarity coefficient (0857)

0982 is the highest value for Morista-Hom similarity coefficient noted from occasion 4 vs

occasion 5 while two tested sampling occasions (4 vs 10 and 6 vs 10) indicate high value for

Bray-Curtis similarity coefficient (075)

The species diversity of small mammals in Kubah National Park (080) is higher than Sarna Jaya

Nature Reserve (046) In conclusion Sarna Jaya Nature Reserve which classified as small

island area comprise of a smaller number in terms of animal species composition due to limited

resources in various aspects (food shelter area) compared to a much wider area which

surrounded by large forested area (Kubah National Park)

CHAPTER ONE

Introduction

11 General Introduction

Ecological studies can be divided into two components extensive studies and intensive studies

According to Southwood and Henderson (2000) extensive studies frequently carried out to

present an infonnation on distribution and abundance for supplementary conservation and

management program in which the samples area are much larger than intensive studies Intensive

studies generate infonnation about the spatial pattern of populations and it is often possible to

relay the level of the population to oceanographic or climatic factors (Southwood amp Henderson

2000) In many communities studies ecologists acquire a list of the species composition that

occurs in each of several communities and if the quantitative sampling has been conducted some

measure of the relative abundance of each species (Krebs 1999)

Mostly research which been carried out is more focused on species diversity only and just a little

previous tudy been done to quantify the species similarity in addition to species diversity

Quantifying similarity and diversity of animals in tenn of species composition and abundance

will provide useful information about the population of the animal species at the particular study

sites (Magurran 2004)

Species similarity signify the similarity of each study or sample or sampling unit to each other

while the diversity of each unit to one another been signify as species diversity (Krebs 1999) It

is the intension of this study to address both species similarity and species diversity analysis

simultaneously on repetitive sampling of small mammals done on an open and closed habitat

12 Species Diversity

Krebs (1999) noted that a biological community has an attribute of species diversity and recently

there are many different ways have been suggested for measuring the species diversity Basically

it depends on the objective for the study conducted and the information that we want to see from

the samples collected Diversity measures require an estimate of species importance in the

community (Krebs 1999)

Species diversity for this aspect can be defined as the number of different species in a particular

area (species richness) weighted by some measure of abundance such as number of individuals or

biomass (Magurran 1998) Species evenness is part of the measures of species diversity which is

the relative abundance with which each species is represented in the particular area Species

evenness is a measure of biodiversity which qualifies how equal the community is numerically

Evenness is also a part of species diversity measure which compares the similarity of the

population size of each of the species present

Species richness and species evenness are probably the most frequently used measures of the

total biodiversity of the region (Magurran 1998 2004) Species richness noted that the observed

2

species number increases non-linearly with sampling effort Species richness and evenness are

component of biodiversity that mayor may not be correlated with one another and with pattern of

species abundance Gotelli and Colwell (2001) stated that standardising by the number of

individual collected and standardising by area or sampling effort can lead to the different

conclusions regarding species richness

According to Southwood and Henderson (2000) diversity can be divided into three categories

(a) a diversity- the diversity of species within a community or habitat

(b) f3 diversity- the measure of the rate and extent of change in species along a gradient from

one habitat to others and

(c) y diversity- the richness in species of a range of a habitats in a geographical area which

is a consequence of the a diversity of the habitats together with the extent of the (3 diversity

between them

Shannon index is one of several diversity indices used to measure diversity in categorical data

According to Krebs (1999) Shannon index is used for rare species while Simpson index is used

which emphasize the common species The advantage of Shannon index is it takes into account

the number of species and the evenness of the species index is increased either by having

additional unique species or by having better species evenness The Shannon index is the

measure of infonnation content should be used only on random samples drawn from a large

community in which the total number of species is known (Krebs 1999)

3

Shannon index is the most popular measures of the species diversity which based on infonnation

theory According to Krebs (1999) there are four types of infonnation that might be collected

regarding order in the community

(8) The number of species

(b) The number of individuals in each species

(c) The places occupied by individuals of each species and

(d) The places occupied by the individuals as separate individuals

Simpson index also been used to quantify species diversity of small mammals derived by

Simpson (1943) The basis of this index is the probability of two individuals being conspecifics

Here Simpsons Reciprocal Index (110) is used where the values start 1 ([owest possible

figures) and it represents a community containing only one species to the maximum number

which represent the total number of species caught

According to Lande (1996) the species richness Shannon infonnation and Simpson diversity are

the most commonly used nonparametric measures of species diversity The proportion of the total

diversity found within communities provides a natural measure of similarity among multiple

communities The expected similarity among multiple random samples from the same depends

on the number of samples and on the underlying measures of diversity Measures of species

divers~ play a central role in ecology and conservation biology which giving the number of

species composition and the abundance of animals at the particular area

13 Species Similarity

Krebs (1999) noted that resemblance measure can be expressed either (a) similarity degree of

resemblance or (b) dissimilarity degree of difference Magurran (2004) stated that similarity or

dissimilarity indices provide quantitative bases of assessment in comparing species composition

and biodiversity of two or more assemblages in taxonomic and ecological research Krebs (1999)

stated that we need to use similarity coefficients or similarity indices that give some measure of

the relative abundance of each species in the two samples if we are dealing to quantify the

similarity oftwo such samples or community

Similarity matrix is the opposite concept to the distance matrix The elements of a similarity

matrix measure pairwise similarities of objects The greater similarity of two objects will

produced the high value of the measure Each similarity measures has its own properties and

generally gives different perspectives of the data turning the matter of choice not trivial

(Laurenco et al 2004)

According to Boyce and Ellison (2001) and Krebs (1999) similarity indices can be divided into

two major classes first is those that include joint absences or zero-zero matches (species that are

in neither of the two samples for which a similarity is being computed but are present in at least

one other plot in the study) and second class is those that do not include the zero-zero matches

Kubah National Park is classified as a geographically open habitat for this study A total of 98

small mammals were captured in a total of 5000 trapnights consisting of 10 species namely

Maxomys rajah M surifer M whiteheadi Leopoldamys sabanus Lariscus insignis

Sundascuirus lowi Tupaia tana T dorsalis T glis and Echinosorex gymnlllUs from four

families (Erinaceidae Scuiridae Tupaiidae and Muridae) of orders (Rodentia Scandentia and

Insectivora) Species similarity of small mammals in 10 repetitive sampling occasions showed

differences in term of similarity value for four similarity indices All similarity indices noted 0

value for three tested sampling occasions (1 vs 8 5 vs 8 and 8 vs 9) which indicates that there

are no shared species between two tested sampling occasions Occasion 9 vs occasion 10 noted

high value for Jaccard similarity coefficient (075) and Sorensen similarity coefficient (0857)

0982 is the highest value for Morista-Hom similarity coefficient noted from occasion 4 vs

occasion 5 while two tested sampling occasions (4 vs 10 and 6 vs 10) indicate high value for

Bray-Curtis similarity coefficient (075)

The species diversity of small mammals in Kubah National Park (080) is higher than Sarna Jaya

Nature Reserve (046) In conclusion Sarna Jaya Nature Reserve which classified as small

island area comprise of a smaller number in terms of animal species composition due to limited

resources in various aspects (food shelter area) compared to a much wider area which

surrounded by large forested area (Kubah National Park)

CHAPTER ONE

Introduction

11 General Introduction

Ecological studies can be divided into two components extensive studies and intensive studies

According to Southwood and Henderson (2000) extensive studies frequently carried out to

present an infonnation on distribution and abundance for supplementary conservation and

management program in which the samples area are much larger than intensive studies Intensive

studies generate infonnation about the spatial pattern of populations and it is often possible to

relay the level of the population to oceanographic or climatic factors (Southwood amp Henderson

2000) In many communities studies ecologists acquire a list of the species composition that

occurs in each of several communities and if the quantitative sampling has been conducted some

measure of the relative abundance of each species (Krebs 1999)

Mostly research which been carried out is more focused on species diversity only and just a little

previous tudy been done to quantify the species similarity in addition to species diversity

Quantifying similarity and diversity of animals in tenn of species composition and abundance

will provide useful information about the population of the animal species at the particular study

sites (Magurran 2004)

Species similarity signify the similarity of each study or sample or sampling unit to each other

while the diversity of each unit to one another been signify as species diversity (Krebs 1999) It

is the intension of this study to address both species similarity and species diversity analysis

simultaneously on repetitive sampling of small mammals done on an open and closed habitat

12 Species Diversity

Krebs (1999) noted that a biological community has an attribute of species diversity and recently

there are many different ways have been suggested for measuring the species diversity Basically

it depends on the objective for the study conducted and the information that we want to see from

the samples collected Diversity measures require an estimate of species importance in the

community (Krebs 1999)

Species diversity for this aspect can be defined as the number of different species in a particular

area (species richness) weighted by some measure of abundance such as number of individuals or

biomass (Magurran 1998) Species evenness is part of the measures of species diversity which is

the relative abundance with which each species is represented in the particular area Species

evenness is a measure of biodiversity which qualifies how equal the community is numerically

Evenness is also a part of species diversity measure which compares the similarity of the

population size of each of the species present

Species richness and species evenness are probably the most frequently used measures of the

total biodiversity of the region (Magurran 1998 2004) Species richness noted that the observed

2

species number increases non-linearly with sampling effort Species richness and evenness are

component of biodiversity that mayor may not be correlated with one another and with pattern of

species abundance Gotelli and Colwell (2001) stated that standardising by the number of

individual collected and standardising by area or sampling effort can lead to the different

conclusions regarding species richness

According to Southwood and Henderson (2000) diversity can be divided into three categories

(a) a diversity- the diversity of species within a community or habitat

(b) f3 diversity- the measure of the rate and extent of change in species along a gradient from

one habitat to others and

(c) y diversity- the richness in species of a range of a habitats in a geographical area which

is a consequence of the a diversity of the habitats together with the extent of the (3 diversity

between them

Shannon index is one of several diversity indices used to measure diversity in categorical data

According to Krebs (1999) Shannon index is used for rare species while Simpson index is used

which emphasize the common species The advantage of Shannon index is it takes into account

the number of species and the evenness of the species index is increased either by having

additional unique species or by having better species evenness The Shannon index is the

measure of infonnation content should be used only on random samples drawn from a large

community in which the total number of species is known (Krebs 1999)

3

Shannon index is the most popular measures of the species diversity which based on infonnation

theory According to Krebs (1999) there are four types of infonnation that might be collected

regarding order in the community

(8) The number of species

(b) The number of individuals in each species

(c) The places occupied by individuals of each species and

(d) The places occupied by the individuals as separate individuals

Simpson index also been used to quantify species diversity of small mammals derived by

Simpson (1943) The basis of this index is the probability of two individuals being conspecifics

Here Simpsons Reciprocal Index (110) is used where the values start 1 ([owest possible

figures) and it represents a community containing only one species to the maximum number

which represent the total number of species caught

According to Lande (1996) the species richness Shannon infonnation and Simpson diversity are

the most commonly used nonparametric measures of species diversity The proportion of the total

diversity found within communities provides a natural measure of similarity among multiple

communities The expected similarity among multiple random samples from the same depends

on the number of samples and on the underlying measures of diversity Measures of species

divers~ play a central role in ecology and conservation biology which giving the number of

species composition and the abundance of animals at the particular area

13 Species Similarity

Krebs (1999) noted that resemblance measure can be expressed either (a) similarity degree of

resemblance or (b) dissimilarity degree of difference Magurran (2004) stated that similarity or

dissimilarity indices provide quantitative bases of assessment in comparing species composition

and biodiversity of two or more assemblages in taxonomic and ecological research Krebs (1999)

stated that we need to use similarity coefficients or similarity indices that give some measure of

the relative abundance of each species in the two samples if we are dealing to quantify the

similarity oftwo such samples or community

Similarity matrix is the opposite concept to the distance matrix The elements of a similarity

matrix measure pairwise similarities of objects The greater similarity of two objects will

produced the high value of the measure Each similarity measures has its own properties and

generally gives different perspectives of the data turning the matter of choice not trivial

(Laurenco et al 2004)

According to Boyce and Ellison (2001) and Krebs (1999) similarity indices can be divided into

two major classes first is those that include joint absences or zero-zero matches (species that are

in neither of the two samples for which a similarity is being computed but are present in at least

one other plot in the study) and second class is those that do not include the zero-zero matches

Abstract

( Research on species similarity and species diversity of small mammals in 10 repetitive sampling

occasions (500 trap nights) was conducted in two different habitats an open and closed habitat

The first sampling were carried out in Sarna Jaya Nature Reserve (SJNR) from April to

September 2008 and second sampling conducted in Kubah National Park (KNP) from February

to June 2009 Closed model was chosen where sampling was conducted for five consecutive trap

days in 10 repetitive sessions each session has about five days to one week rest A hundred of

cage traps were set up and placed in grid system at each study site respectively and markshy

recapture method were used to capture the small mammals l

Sarna Jaya Nature Reserve situated in Kuching Sarawak can be classified as geographically

closed habitat or an island habitat A total of 330 individuals of small mammals been trapped in

5000 trapnights consist of six species namely Calloscuirus notatus C prevostii borneensis

Sundamys muelleri Tupaia tana T minor and Rhinoscuirus lauticaudatlls from three families

(Tupaiidae Scuiridae and Muridae) and from two orders (Scandentia and Rodentia) Species

similarities of small mammals species composition on 10 repetitive sampling occasions from

SJNR were calculated and analysed Jaccard similarity coefficient and Sorensen similarity

coefficient indicated a value of 1 in seven tested sampling occasions (3 vs 4 3 vs 5 4 vs 5 3 vs

9 4 vs 9 5 vs 9 and 2 vs 10) Occasion 7 vs occasion 10 noted high values for Morisita-Hom

similarity coefficient (0991) and 0909 is the highest value for Bray-Curtis similarity coefficient

(occasion 9 vs occasion 10) The differences of value for four similarity coefficient indices may

he influenced by factors like sample size and abundance of most abundant species

v

Kubah National Park is classified as a geographically open habitat for this study A total of 98

small mammals were captured in a total of 5000 trapnights consisting of 10 species namely

Maxomys rajah M surifer M whiteheadi Leopoldamys sabanus Lariscus insignis

Sundascuirus lowi Tupaia tana T dorsalis T glis and Echinosorex gymnlllUs from four

families (Erinaceidae Scuiridae Tupaiidae and Muridae) of orders (Rodentia Scandentia and

Insectivora) Species similarity of small mammals in 10 repetitive sampling occasions showed

differences in term of similarity value for four similarity indices All similarity indices noted 0

value for three tested sampling occasions (1 vs 8 5 vs 8 and 8 vs 9) which indicates that there

are no shared species between two tested sampling occasions Occasion 9 vs occasion 10 noted

high value for Jaccard similarity coefficient (075) and Sorensen similarity coefficient (0857)

0982 is the highest value for Morista-Hom similarity coefficient noted from occasion 4 vs

occasion 5 while two tested sampling occasions (4 vs 10 and 6 vs 10) indicate high value for

Bray-Curtis similarity coefficient (075)

The species diversity of small mammals in Kubah National Park (080) is higher than Sarna Jaya

Nature Reserve (046) In conclusion Sarna Jaya Nature Reserve which classified as small

island area comprise of a smaller number in terms of animal species composition due to limited

resources in various aspects (food shelter area) compared to a much wider area which

surrounded by large forested area (Kubah National Park)

CHAPTER ONE

Introduction

11 General Introduction

Ecological studies can be divided into two components extensive studies and intensive studies

According to Southwood and Henderson (2000) extensive studies frequently carried out to

present an infonnation on distribution and abundance for supplementary conservation and

management program in which the samples area are much larger than intensive studies Intensive

studies generate infonnation about the spatial pattern of populations and it is often possible to

relay the level of the population to oceanographic or climatic factors (Southwood amp Henderson

2000) In many communities studies ecologists acquire a list of the species composition that

occurs in each of several communities and if the quantitative sampling has been conducted some

measure of the relative abundance of each species (Krebs 1999)

Mostly research which been carried out is more focused on species diversity only and just a little

previous tudy been done to quantify the species similarity in addition to species diversity

Quantifying similarity and diversity of animals in tenn of species composition and abundance

will provide useful information about the population of the animal species at the particular study

sites (Magurran 2004)

Species similarity signify the similarity of each study or sample or sampling unit to each other

while the diversity of each unit to one another been signify as species diversity (Krebs 1999) It

is the intension of this study to address both species similarity and species diversity analysis

simultaneously on repetitive sampling of small mammals done on an open and closed habitat

12 Species Diversity

Krebs (1999) noted that a biological community has an attribute of species diversity and recently

there are many different ways have been suggested for measuring the species diversity Basically

it depends on the objective for the study conducted and the information that we want to see from

the samples collected Diversity measures require an estimate of species importance in the

community (Krebs 1999)

Species diversity for this aspect can be defined as the number of different species in a particular

area (species richness) weighted by some measure of abundance such as number of individuals or

biomass (Magurran 1998) Species evenness is part of the measures of species diversity which is

the relative abundance with which each species is represented in the particular area Species

evenness is a measure of biodiversity which qualifies how equal the community is numerically

Evenness is also a part of species diversity measure which compares the similarity of the

population size of each of the species present

Species richness and species evenness are probably the most frequently used measures of the

total biodiversity of the region (Magurran 1998 2004) Species richness noted that the observed

2

species number increases non-linearly with sampling effort Species richness and evenness are

component of biodiversity that mayor may not be correlated with one another and with pattern of

species abundance Gotelli and Colwell (2001) stated that standardising by the number of

individual collected and standardising by area or sampling effort can lead to the different

conclusions regarding species richness

According to Southwood and Henderson (2000) diversity can be divided into three categories

(a) a diversity- the diversity of species within a community or habitat

(b) f3 diversity- the measure of the rate and extent of change in species along a gradient from

one habitat to others and

(c) y diversity- the richness in species of a range of a habitats in a geographical area which

is a consequence of the a diversity of the habitats together with the extent of the (3 diversity

between them

Shannon index is one of several diversity indices used to measure diversity in categorical data

According to Krebs (1999) Shannon index is used for rare species while Simpson index is used

which emphasize the common species The advantage of Shannon index is it takes into account

the number of species and the evenness of the species index is increased either by having

additional unique species or by having better species evenness The Shannon index is the

measure of infonnation content should be used only on random samples drawn from a large

community in which the total number of species is known (Krebs 1999)

3

Shannon index is the most popular measures of the species diversity which based on infonnation

theory According to Krebs (1999) there are four types of infonnation that might be collected

regarding order in the community

(8) The number of species

(b) The number of individuals in each species

(c) The places occupied by individuals of each species and

(d) The places occupied by the individuals as separate individuals

Simpson index also been used to quantify species diversity of small mammals derived by

Simpson (1943) The basis of this index is the probability of two individuals being conspecifics

Here Simpsons Reciprocal Index (110) is used where the values start 1 ([owest possible

figures) and it represents a community containing only one species to the maximum number

which represent the total number of species caught

According to Lande (1996) the species richness Shannon infonnation and Simpson diversity are

the most commonly used nonparametric measures of species diversity The proportion of the total

diversity found within communities provides a natural measure of similarity among multiple

communities The expected similarity among multiple random samples from the same depends

on the number of samples and on the underlying measures of diversity Measures of species

divers~ play a central role in ecology and conservation biology which giving the number of

species composition and the abundance of animals at the particular area

13 Species Similarity

Krebs (1999) noted that resemblance measure can be expressed either (a) similarity degree of

resemblance or (b) dissimilarity degree of difference Magurran (2004) stated that similarity or

dissimilarity indices provide quantitative bases of assessment in comparing species composition

and biodiversity of two or more assemblages in taxonomic and ecological research Krebs (1999)

stated that we need to use similarity coefficients or similarity indices that give some measure of

the relative abundance of each species in the two samples if we are dealing to quantify the

similarity oftwo such samples or community

Similarity matrix is the opposite concept to the distance matrix The elements of a similarity

matrix measure pairwise similarities of objects The greater similarity of two objects will

produced the high value of the measure Each similarity measures has its own properties and

generally gives different perspectives of the data turning the matter of choice not trivial

(Laurenco et al 2004)

According to Boyce and Ellison (2001) and Krebs (1999) similarity indices can be divided into

two major classes first is those that include joint absences or zero-zero matches (species that are

in neither of the two samples for which a similarity is being computed but are present in at least

one other plot in the study) and second class is those that do not include the zero-zero matches

Abstract

( Research on species similarity and species diversity of small mammals in 10 repetitive sampling

occasions (500 trap nights) was conducted in two different habitats an open and closed habitat

The first sampling were carried out in Sarna Jaya Nature Reserve (SJNR) from April to

September 2008 and second sampling conducted in Kubah National Park (KNP) from February

to June 2009 Closed model was chosen where sampling was conducted for five consecutive trap

days in 10 repetitive sessions each session has about five days to one week rest A hundred of

cage traps were set up and placed in grid system at each study site respectively and markshy

recapture method were used to capture the small mammals l

Sarna Jaya Nature Reserve situated in Kuching Sarawak can be classified as geographically

closed habitat or an island habitat A total of 330 individuals of small mammals been trapped in

5000 trapnights consist of six species namely Calloscuirus notatus C prevostii borneensis

Sundamys muelleri Tupaia tana T minor and Rhinoscuirus lauticaudatlls from three families

(Tupaiidae Scuiridae and Muridae) and from two orders (Scandentia and Rodentia) Species

similarities of small mammals species composition on 10 repetitive sampling occasions from

SJNR were calculated and analysed Jaccard similarity coefficient and Sorensen similarity

coefficient indicated a value of 1 in seven tested sampling occasions (3 vs 4 3 vs 5 4 vs 5 3 vs

9 4 vs 9 5 vs 9 and 2 vs 10) Occasion 7 vs occasion 10 noted high values for Morisita-Hom

similarity coefficient (0991) and 0909 is the highest value for Bray-Curtis similarity coefficient

(occasion 9 vs occasion 10) The differences of value for four similarity coefficient indices may

he influenced by factors like sample size and abundance of most abundant species

v

Kubah National Park is classified as a geographically open habitat for this study A total of 98

small mammals were captured in a total of 5000 trapnights consisting of 10 species namely

Maxomys rajah M surifer M whiteheadi Leopoldamys sabanus Lariscus insignis

Sundascuirus lowi Tupaia tana T dorsalis T glis and Echinosorex gymnlllUs from four

families (Erinaceidae Scuiridae Tupaiidae and Muridae) of orders (Rodentia Scandentia and

Insectivora) Species similarity of small mammals in 10 repetitive sampling occasions showed

differences in term of similarity value for four similarity indices All similarity indices noted 0

value for three tested sampling occasions (1 vs 8 5 vs 8 and 8 vs 9) which indicates that there

are no shared species between two tested sampling occasions Occasion 9 vs occasion 10 noted

high value for Jaccard similarity coefficient (075) and Sorensen similarity coefficient (0857)

0982 is the highest value for Morista-Hom similarity coefficient noted from occasion 4 vs

occasion 5 while two tested sampling occasions (4 vs 10 and 6 vs 10) indicate high value for

Bray-Curtis similarity coefficient (075)

The species diversity of small mammals in Kubah National Park (080) is higher than Sarna Jaya

Nature Reserve (046) In conclusion Sarna Jaya Nature Reserve which classified as small

island area comprise of a smaller number in terms of animal species composition due to limited

resources in various aspects (food shelter area) compared to a much wider area which

surrounded by large forested area (Kubah National Park)

KEY WORDS- small mammals similarity indices diversity indices repetitive sampling open

CHAPTER ONE

Introduction

11 General Introduction

Ecological studies can be divided into two components extensive studies and intensive studies

According to Southwood and Henderson (2000) extensive studies frequently carried out to

present an infonnation on distribution and abundance for supplementary conservation and

management program in which the samples area are much larger than intensive studies Intensive

studies generate infonnation about the spatial pattern of populations and it is often possible to

relay the level of the population to oceanographic or climatic factors (Southwood amp Henderson

2000) In many communities studies ecologists acquire a list of the species composition that

occurs in each of several communities and if the quantitative sampling has been conducted some

measure of the relative abundance of each species (Krebs 1999)

Mostly research which been carried out is more focused on species diversity only and just a little

previous tudy been done to quantify the species similarity in addition to species diversity

Quantifying similarity and diversity of animals in tenn of species composition and abundance

will provide useful information about the population of the animal species at the particular study

sites (Magurran 2004)

Species similarity signify the similarity of each study or sample or sampling unit to each other

while the diversity of each unit to one another been signify as species diversity (Krebs 1999) It

is the intension of this study to address both species similarity and species diversity analysis

simultaneously on repetitive sampling of small mammals done on an open and closed habitat

12 Species Diversity

Krebs (1999) noted that a biological community has an attribute of species diversity and recently

there are many different ways have been suggested for measuring the species diversity Basically

it depends on the objective for the study conducted and the information that we want to see from

the samples collected Diversity measures require an estimate of species importance in the

community (Krebs 1999)

Species diversity for this aspect can be defined as the number of different species in a particular

area (species richness) weighted by some measure of abundance such as number of individuals or

biomass (Magurran 1998) Species evenness is part of the measures of species diversity which is

the relative abundance with which each species is represented in the particular area Species

evenness is a measure of biodiversity which qualifies how equal the community is numerically

Evenness is also a part of species diversity measure which compares the similarity of the

population size of each of the species present

Species richness and species evenness are probably the most frequently used measures of the

total biodiversity of the region (Magurran 1998 2004) Species richness noted that the observed

2

species number increases non-linearly with sampling effort Species richness and evenness are

component of biodiversity that mayor may not be correlated with one another and with pattern of

species abundance Gotelli and Colwell (2001) stated that standardising by the number of

individual collected and standardising by area or sampling effort can lead to the different

conclusions regarding species richness

According to Southwood and Henderson (2000) diversity can be divided into three categories

(a) a diversity- the diversity of species within a community or habitat

(b) f3 diversity- the measure of the rate and extent of change in species along a gradient from

one habitat to others and

(c) y diversity- the richness in species of a range of a habitats in a geographical area which

is a consequence of the a diversity of the habitats together with the extent of the (3 diversity

between them

Shannon index is one of several diversity indices used to measure diversity in categorical data

According to Krebs (1999) Shannon index is used for rare species while Simpson index is used

which emphasize the common species The advantage of Shannon index is it takes into account

the number of species and the evenness of the species index is increased either by having

additional unique species or by having better species evenness The Shannon index is the

measure of infonnation content should be used only on random samples drawn from a large

community in which the total number of species is known (Krebs 1999)

3

Shannon index is the most popular measures of the species diversity which based on infonnation

theory According to Krebs (1999) there are four types of infonnation that might be collected

regarding order in the community

(8) The number of species

(b) The number of individuals in each species

(c) The places occupied by individuals of each species and

(d) The places occupied by the individuals as separate individuals

Simpson index also been used to quantify species diversity of small mammals derived by

Simpson (1943) The basis of this index is the probability of two individuals being conspecifics

Here Simpsons Reciprocal Index (110) is used where the values start 1 ([owest possible

figures) and it represents a community containing only one species to the maximum number

which represent the total number of species caught

According to Lande (1996) the species richness Shannon infonnation and Simpson diversity are

the most commonly used nonparametric measures of species diversity The proportion of the total

diversity found within communities provides a natural measure of similarity among multiple

communities The expected similarity among multiple random samples from the same depends

on the number of samples and on the underlying measures of diversity Measures of species

divers~ play a central role in ecology and conservation biology which giving the number of

species composition and the abundance of animals at the particular area

13 Species Similarity

Krebs (1999) noted that resemblance measure can be expressed either (a) similarity degree of

resemblance or (b) dissimilarity degree of difference Magurran (2004) stated that similarity or

dissimilarity indices provide quantitative bases of assessment in comparing species composition

and biodiversity of two or more assemblages in taxonomic and ecological research Krebs (1999)

stated that we need to use similarity coefficients or similarity indices that give some measure of

the relative abundance of each species in the two samples if we are dealing to quantify the

similarity oftwo such samples or community

Similarity matrix is the opposite concept to the distance matrix The elements of a similarity

matrix measure pairwise similarities of objects The greater similarity of two objects will

produced the high value of the measure Each similarity measures has its own properties and

generally gives different perspectives of the data turning the matter of choice not trivial

(Laurenco et al 2004)

According to Boyce and Ellison (2001) and Krebs (1999) similarity indices can be divided into

two major classes first is those that include joint absences or zero-zero matches (species that are

in neither of the two samples for which a similarity is being computed but are present in at least

one other plot in the study) and second class is those that do not include the zero-zero matches

Abstract

( Research on species similarity and species diversity of small mammals in 10 repetitive sampling

occasions (500 trap nights) was conducted in two different habitats an open and closed habitat

The first sampling were carried out in Sarna Jaya Nature Reserve (SJNR) from April to

September 2008 and second sampling conducted in Kubah National Park (KNP) from February

to June 2009 Closed model was chosen where sampling was conducted for five consecutive trap

days in 10 repetitive sessions each session has about five days to one week rest A hundred of

cage traps were set up and placed in grid system at each study site respectively and markshy

recapture method were used to capture the small mammals l

Sarna Jaya Nature Reserve situated in Kuching Sarawak can be classified as geographically

closed habitat or an island habitat A total of 330 individuals of small mammals been trapped in

5000 trapnights consist of six species namely Calloscuirus notatus C prevostii borneensis

Sundamys muelleri Tupaia tana T minor and Rhinoscuirus lauticaudatlls from three families

(Tupaiidae Scuiridae and Muridae) and from two orders (Scandentia and Rodentia) Species

similarities of small mammals species composition on 10 repetitive sampling occasions from

SJNR were calculated and analysed Jaccard similarity coefficient and Sorensen similarity

coefficient indicated a value of 1 in seven tested sampling occasions (3 vs 4 3 vs 5 4 vs 5 3 vs

9 4 vs 9 5 vs 9 and 2 vs 10) Occasion 7 vs occasion 10 noted high values for Morisita-Hom

similarity coefficient (0991) and 0909 is the highest value for Bray-Curtis similarity coefficient

(occasion 9 vs occasion 10) The differences of value for four similarity coefficient indices may

he influenced by factors like sample size and abundance of most abundant species

v

Kubah National Park is classified as a geographically open habitat for this study A total of 98

small mammals were captured in a total of 5000 trapnights consisting of 10 species namely

Maxomys rajah M surifer M whiteheadi Leopoldamys sabanus Lariscus insignis

Sundascuirus lowi Tupaia tana T dorsalis T glis and Echinosorex gymnlllUs from four

families (Erinaceidae Scuiridae Tupaiidae and Muridae) of orders (Rodentia Scandentia and

Insectivora) Species similarity of small mammals in 10 repetitive sampling occasions showed

differences in term of similarity value for four similarity indices All similarity indices noted 0

value for three tested sampling occasions (1 vs 8 5 vs 8 and 8 vs 9) which indicates that there

are no shared species between two tested sampling occasions Occasion 9 vs occasion 10 noted

high value for Jaccard similarity coefficient (075) and Sorensen similarity coefficient (0857)

0982 is the highest value for Morista-Hom similarity coefficient noted from occasion 4 vs

occasion 5 while two tested sampling occasions (4 vs 10 and 6 vs 10) indicate high value for

Bray-Curtis similarity coefficient (075)

The species diversity of small mammals in Kubah National Park (080) is higher than Sarna Jaya

Nature Reserve (046) In conclusion Sarna Jaya Nature Reserve which classified as small

island area comprise of a smaller number in terms of animal species composition due to limited

resources in various aspects (food shelter area) compared to a much wider area which

surrounded by large forested area (Kubah National Park)

Abstract

( Research on species similarity and species diversity of small mammals in 10 repetitive sampling

occasions (500 trap nights) was conducted in two different habitats an open and closed habitat

The first sampling were carried out in Sarna Jaya Nature Reserve (SJNR) from April to

September 2008 and second sampling conducted in Kubah National Park (KNP) from February

to June 2009 Closed model was chosen where sampling was conducted for five consecutive trap

days in 10 repetitive sessions each session has about five days to one week rest A hundred of

cage traps were set up and placed in grid system at each study site respectively and markshy

recapture method were used to capture the small mammals l

Sarna Jaya Nature Reserve situated in Kuching Sarawak can be classified as geographically

closed habitat or an island habitat A total of 330 individuals of small mammals been trapped in

5000 trapnights consist of six species namely Calloscuirus notatus C prevostii borneensis

Sundamys muelleri Tupaia tana T minor and Rhinoscuirus lauticaudatlls from three families

(Tupaiidae Scuiridae and Muridae) and from two orders (Scandentia and Rodentia) Species

similarities of small mammals species composition on 10 repetitive sampling occasions from

SJNR were calculated and analysed Jaccard similarity coefficient and Sorensen similarity

coefficient indicated a value of 1 in seven tested sampling occasions (3 vs 4 3 vs 5 4 vs 5 3 vs

9 4 vs 9 5 vs 9 and 2 vs 10) Occasion 7 vs occasion 10 noted high values for Morisita-Hom

similarity coefficient (0991) and 0909 is the highest value for Bray-Curtis similarity coefficient

(occasion 9 vs occasion 10) The differences of value for four similarity coefficient indices may

he influenced by factors like sample size and abundance of most abundant species

v

Kubah National Park is classified as a geographically open habitat for this study A total of 98

small mammals were captured in a total of 5000 trapnights consisting of 10 species namely

Maxomys rajah M surifer M whiteheadi Leopoldamys sabanus Lariscus insignis

Sundascuirus lowi Tupaia tana T dorsalis T glis and Echinosorex gymnlllUs from four

families (Erinaceidae Scuiridae Tupaiidae and Muridae) of orders (Rodentia Scandentia and

Insectivora) Species similarity of small mammals in 10 repetitive sampling occasions showed

differences in term of similarity value for four similarity indices All similarity indices noted 0

value for three tested sampling occasions (1 vs 8 5 vs 8 and 8 vs 9) which indicates that there

are no shared species between two tested sampling occasions Occasion 9 vs occasion 10 noted

high value for Jaccard similarity coefficient (075) and Sorensen similarity coefficient (0857)

0982 is the highest value for Morista-Hom similarity coefficient noted from occasion 4 vs

occasion 5 while two tested sampling occasions (4 vs 10 and 6 vs 10) indicate high value for

Bray-Curtis similarity coefficient (075)

The species diversity of small mammals in Kubah National Park (080) is higher than Sarna Jaya

Nature Reserve (046) In conclusion Sarna Jaya Nature Reserve which classified as small

island area comprise of a smaller number in terms of animal species composition due to limited

resources in various aspects (food shelter area) compared to a much wider area which

surrounded by large forested area (Kubah National Park)

CHAPTER ONE

Introduction

11 General Introduction

Ecological studies can be divided into two components extensive studies and intensive studies

According to Southwood and Henderson (2000) extensive studies frequently carried out to

present an infonnation on distribution and abundance for supplementary conservation and

management program in which the samples area are much larger than intensive studies Intensive

studies generate infonnation about the spatial pattern of populations and it is often possible to

relay the level of the population to oceanographic or climatic factors (Southwood amp Henderson

2000) In many communities studies ecologists acquire a list of the species composition that

occurs in each of several communities and if the quantitative sampling has been conducted some

measure of the relative abundance of each species (Krebs 1999)

Mostly research which been carried out is more focused on species diversity only and just a little

previous tudy been done to quantify the species similarity in addition to species diversity

Quantifying similarity and diversity of animals in tenn of species composition and abundance

will provide useful information about the population of the animal species at the particular study

sites (Magurran 2004)

Species similarity signify the similarity of each study or sample or sampling unit to each other

while the diversity of each unit to one another been signify as species diversity (Krebs 1999) It

is the intension of this study to address both species similarity and species diversity analysis

simultaneously on repetitive sampling of small mammals done on an open and closed habitat

12 Species Diversity

Krebs (1999) noted that a biological community has an attribute of species diversity and recently

there are many different ways have been suggested for measuring the species diversity Basically

it depends on the objective for the study conducted and the information that we want to see from

the samples collected Diversity measures require an estimate of species importance in the

community (Krebs 1999)

Species diversity for this aspect can be defined as the number of different species in a particular

area (species richness) weighted by some measure of abundance such as number of individuals or

biomass (Magurran 1998) Species evenness is part of the measures of species diversity which is

the relative abundance with which each species is represented in the particular area Species

evenness is a measure of biodiversity which qualifies how equal the community is numerically

Evenness is also a part of species diversity measure which compares the similarity of the

population size of each of the species present

Species richness and species evenness are probably the most frequently used measures of the

total biodiversity of the region (Magurran 1998 2004) Species richness noted that the observed

2

species number increases non-linearly with sampling effort Species richness and evenness are

component of biodiversity that mayor may not be correlated with one another and with pattern of

species abundance Gotelli and Colwell (2001) stated that standardising by the number of

individual collected and standardising by area or sampling effort can lead to the different

conclusions regarding species richness

According to Southwood and Henderson (2000) diversity can be divided into three categories

(a) a diversity- the diversity of species within a community or habitat

(b) f3 diversity- the measure of the rate and extent of change in species along a gradient from

one habitat to others and

(c) y diversity- the richness in species of a range of a habitats in a geographical area which

is a consequence of the a diversity of the habitats together with the extent of the (3 diversity

between them

Shannon index is one of several diversity indices used to measure diversity in categorical data

According to Krebs (1999) Shannon index is used for rare species while Simpson index is used

which emphasize the common species The advantage of Shannon index is it takes into account

the number of species and the evenness of the species index is increased either by having

additional unique species or by having better species evenness The Shannon index is the

measure of infonnation content should be used only on random samples drawn from a large

community in which the total number of species is known (Krebs 1999)

3

Shannon index is the most popular measures of the species diversity which based on infonnation

theory According to Krebs (1999) there are four types of infonnation that might be collected

regarding order in the community

(8) The number of species

(b) The number of individuals in each species

(c) The places occupied by individuals of each species and

(d) The places occupied by the individuals as separate individuals

Simpson index also been used to quantify species diversity of small mammals derived by

Simpson (1943) The basis of this index is the probability of two individuals being conspecifics

Here Simpsons Reciprocal Index (110) is used where the values start 1 ([owest possible

figures) and it represents a community containing only one species to the maximum number

which represent the total number of species caught

According to Lande (1996) the species richness Shannon infonnation and Simpson diversity are

the most commonly used nonparametric measures of species diversity The proportion of the total

diversity found within communities provides a natural measure of similarity among multiple

communities The expected similarity among multiple random samples from the same depends

on the number of samples and on the underlying measures of diversity Measures of species

divers~ play a central role in ecology and conservation biology which giving the number of

species composition and the abundance of animals at the particular area

13 Species Similarity

Krebs (1999) noted that resemblance measure can be expressed either (a) similarity degree of

resemblance or (b) dissimilarity degree of difference Magurran (2004) stated that similarity or

dissimilarity indices provide quantitative bases of assessment in comparing species composition

and biodiversity of two or more assemblages in taxonomic and ecological research Krebs (1999)

stated that we need to use similarity coefficients or similarity indices that give some measure of

the relative abundance of each species in the two samples if we are dealing to quantify the

similarity oftwo such samples or community

Similarity matrix is the opposite concept to the distance matrix The elements of a similarity

matrix measure pairwise similarities of objects The greater similarity of two objects will

produced the high value of the measure Each similarity measures has its own properties and

generally gives different perspectives of the data turning the matter of choice not trivial

(Laurenco et al 2004)

According to Boyce and Ellison (2001) and Krebs (1999) similarity indices can be divided into

two major classes first is those that include joint absences or zero-zero matches (species that are

in neither of the two samples for which a similarity is being computed but are present in at least

one other plot in the study) and second class is those that do not include the zero-zero matches

Abstract

( Research on species similarity and species diversity of small mammals in 10 repetitive sampling

occasions (500 trap nights) was conducted in two different habitats an open and closed habitat

The first sampling were carried out in Sarna Jaya Nature Reserve (SJNR) from April to

September 2008 and second sampling conducted in Kubah National Park (KNP) from February

to June 2009 Closed model was chosen where sampling was conducted for five consecutive trap

days in 10 repetitive sessions each session has about five days to one week rest A hundred of

cage traps were set up and placed in grid system at each study site respectively and markshy

recapture method were used to capture the small mammals l

Sarna Jaya Nature Reserve situated in Kuching Sarawak can be classified as geographically

closed habitat or an island habitat A total of 330 individuals of small mammals been trapped in

5000 trapnights consist of six species namely Calloscuirus notatus C prevostii borneensis

Sundamys muelleri Tupaia tana T minor and Rhinoscuirus lauticaudatlls from three families

(Tupaiidae Scuiridae and Muridae) and from two orders (Scandentia and Rodentia) Species

similarities of small mammals species composition on 10 repetitive sampling occasions from

SJNR were calculated and analysed Jaccard similarity coefficient and Sorensen similarity

coefficient indicated a value of 1 in seven tested sampling occasions (3 vs 4 3 vs 5 4 vs 5 3 vs

9 4 vs 9 5 vs 9 and 2 vs 10) Occasion 7 vs occasion 10 noted high values for Morisita-Hom

similarity coefficient (0991) and 0909 is the highest value for Bray-Curtis similarity coefficient

(occasion 9 vs occasion 10) The differences of value for four similarity coefficient indices may

he influenced by factors like sample size and abundance of most abundant species

v

Kubah National Park is classified as a geographically open habitat for this study A total of 98

small mammals were captured in a total of 5000 trapnights consisting of 10 species namely

Maxomys rajah M surifer M whiteheadi Leopoldamys sabanus Lariscus insignis

Sundascuirus lowi Tupaia tana T dorsalis T glis and Echinosorex gymnlllUs from four

families (Erinaceidae Scuiridae Tupaiidae and Muridae) of orders (Rodentia Scandentia and

Insectivora) Species similarity of small mammals in 10 repetitive sampling occasions showed

differences in term of similarity value for four similarity indices All similarity indices noted 0

value for three tested sampling occasions (1 vs 8 5 vs 8 and 8 vs 9) which indicates that there

are no shared species between two tested sampling occasions Occasion 9 vs occasion 10 noted

high value for Jaccard similarity coefficient (075) and Sorensen similarity coefficient (0857)

0982 is the highest value for Morista-Hom similarity coefficient noted from occasion 4 vs

occasion 5 while two tested sampling occasions (4 vs 10 and 6 vs 10) indicate high value for

Bray-Curtis similarity coefficient (075)

The species diversity of small mammals in Kubah National Park (080) is higher than Sarna Jaya

Nature Reserve (046) In conclusion Sarna Jaya Nature Reserve which classified as small

island area comprise of a smaller number in terms of animal species composition due to limited

resources in various aspects (food shelter area) compared to a much wider area which

surrounded by large forested area (Kubah National Park)

CHAPTER ONE

Introduction

11 General Introduction

Ecological studies can be divided into two components extensive studies and intensive studies

According to Southwood and Henderson (2000) extensive studies frequently carried out to

present an infonnation on distribution and abundance for supplementary conservation and

management program in which the samples area are much larger than intensive studies Intensive

studies generate infonnation about the spatial pattern of populations and it is often possible to

relay the level of the population to oceanographic or climatic factors (Southwood amp Henderson

2000) In many communities studies ecologists acquire a list of the species composition that

occurs in each of several communities and if the quantitative sampling has been conducted some

measure of the relative abundance of each species (Krebs 1999)

Mostly research which been carried out is more focused on species diversity only and just a little

previous tudy been done to quantify the species similarity in addition to species diversity

Quantifying similarity and diversity of animals in tenn of species composition and abundance

will provide useful information about the population of the animal species at the particular study

sites (Magurran 2004)

Species similarity signify the similarity of each study or sample or sampling unit to each other

while the diversity of each unit to one another been signify as species diversity (Krebs 1999) It

is the intension of this study to address both species similarity and species diversity analysis

simultaneously on repetitive sampling of small mammals done on an open and closed habitat

12 Species Diversity

Krebs (1999) noted that a biological community has an attribute of species diversity and recently

there are many different ways have been suggested for measuring the species diversity Basically

it depends on the objective for the study conducted and the information that we want to see from

the samples collected Diversity measures require an estimate of species importance in the

community (Krebs 1999)

Species diversity for this aspect can be defined as the number of different species in a particular

area (species richness) weighted by some measure of abundance such as number of individuals or

biomass (Magurran 1998) Species evenness is part of the measures of species diversity which is

the relative abundance with which each species is represented in the particular area Species

evenness is a measure of biodiversity which qualifies how equal the community is numerically

Evenness is also a part of species diversity measure which compares the similarity of the

population size of each of the species present

Species richness and species evenness are probably the most frequently used measures of the

total biodiversity of the region (Magurran 1998 2004) Species richness noted that the observed

2

species number increases non-linearly with sampling effort Species richness and evenness are

component of biodiversity that mayor may not be correlated with one another and with pattern of

species abundance Gotelli and Colwell (2001) stated that standardising by the number of

individual collected and standardising by area or sampling effort can lead to the different

conclusions regarding species richness

According to Southwood and Henderson (2000) diversity can be divided into three categories

(a) a diversity- the diversity of species within a community or habitat

(b) f3 diversity- the measure of the rate and extent of change in species along a gradient from

one habitat to others and

(c) y diversity- the richness in species of a range of a habitats in a geographical area which

is a consequence of the a diversity of the habitats together with the extent of the (3 diversity

between them

Shannon index is one of several diversity indices used to measure diversity in categorical data

According to Krebs (1999) Shannon index is used for rare species while Simpson index is used

which emphasize the common species The advantage of Shannon index is it takes into account

the number of species and the evenness of the species index is increased either by having

additional unique species or by having better species evenness The Shannon index is the

measure of infonnation content should be used only on random samples drawn from a large

community in which the total number of species is known (Krebs 1999)

3

Shannon index is the most popular measures of the species diversity which based on infonnation

theory According to Krebs (1999) there are four types of infonnation that might be collected

regarding order in the community

(8) The number of species

(b) The number of individuals in each species

(c) The places occupied by individuals of each species and

(d) The places occupied by the individuals as separate individuals

Simpson index also been used to quantify species diversity of small mammals derived by

Simpson (1943) The basis of this index is the probability of two individuals being conspecifics

Here Simpsons Reciprocal Index (110) is used where the values start 1 ([owest possible

figures) and it represents a community containing only one species to the maximum number

which represent the total number of species caught

According to Lande (1996) the species richness Shannon infonnation and Simpson diversity are

the most commonly used nonparametric measures of species diversity The proportion of the total

diversity found within communities provides a natural measure of similarity among multiple

communities The expected similarity among multiple random samples from the same depends

on the number of samples and on the underlying measures of diversity Measures of species

divers~ play a central role in ecology and conservation biology which giving the number of

species composition and the abundance of animals at the particular area

13 Species Similarity

Krebs (1999) noted that resemblance measure can be expressed either (a) similarity degree of

resemblance or (b) dissimilarity degree of difference Magurran (2004) stated that similarity or

dissimilarity indices provide quantitative bases of assessment in comparing species composition

and biodiversity of two or more assemblages in taxonomic and ecological research Krebs (1999)

stated that we need to use similarity coefficients or similarity indices that give some measure of

the relative abundance of each species in the two samples if we are dealing to quantify the

similarity oftwo such samples or community

Similarity matrix is the opposite concept to the distance matrix The elements of a similarity

matrix measure pairwise similarities of objects The greater similarity of two objects will

produced the high value of the measure Each similarity measures has its own properties and

generally gives different perspectives of the data turning the matter of choice not trivial

(Laurenco et al 2004)

According to Boyce and Ellison (2001) and Krebs (1999) similarity indices can be divided into

two major classes first is those that include joint absences or zero-zero matches (species that are

in neither of the two samples for which a similarity is being computed but are present in at least

one other plot in the study) and second class is those that do not include the zero-zero matches

5

Kubah National Park is classified as a geographically open habitat for this study A total of 98

small mammals were captured in a total of 5000 trapnights consisting of 10 species namely

Maxomys rajah M surifer M whiteheadi Leopoldamys sabanus Lariscus insignis

Sundascuirus lowi Tupaia tana T dorsalis T glis and Echinosorex gymnlllUs from four

families (Erinaceidae Scuiridae Tupaiidae and Muridae) of orders (Rodentia Scandentia and

Insectivora) Species similarity of small mammals in 10 repetitive sampling occasions showed

differences in term of similarity value for four similarity indices All similarity indices noted 0

value for three tested sampling occasions (1 vs 8 5 vs 8 and 8 vs 9) which indicates that there

are no shared species between two tested sampling occasions Occasion 9 vs occasion 10 noted

high value for Jaccard similarity coefficient (075) and Sorensen similarity coefficient (0857)

0982 is the highest value for Morista-Hom similarity coefficient noted from occasion 4 vs

occasion 5 while two tested sampling occasions (4 vs 10 and 6 vs 10) indicate high value for

Bray-Curtis similarity coefficient (075)

The species diversity of small mammals in Kubah National Park (080) is higher than Sarna Jaya

Nature Reserve (046) In conclusion Sarna Jaya Nature Reserve which classified as small

island area comprise of a smaller number in terms of animal species composition due to limited

resources in various aspects (food shelter area) compared to a much wider area which

surrounded by large forested area (Kubah National Park)

community (Krebs 1999)

Species diversity for this aspect can be defined as the number of different species in a particular

area (species richness) weighted by some measure of abundance such as number of individuals or

biomass (Magurran 1998) Species evenness is part of the measures of species diversity which is

the relative abundance with which each species is represented in the particular area Species

evenness is a measure of biodiversity which qualifies how equal the community is numerically

Evenness is also a part of species diversity measure which compares the similarity of the

population size of each of the species present

Species richness and species evenness are probably the most frequently used measures of the

total biodiversity of the region (Magurran 1998 2004) Species richness noted that the observed

2

species number increases non-linearly with sampling effort Species richness and evenness are

component of biodiversity that mayor may not be correlated with one another and with pattern of

species abundance Gotelli and Colwell (2001) stated that standardising by the number of

individual collected and standardising by area or sampling effort can lead to the different

conclusions regarding species richness

According to Southwood and Henderson (2000) diversity can be divided into three categories

(a) a diversity- the diversity of species within a community or habitat

(b) f3 diversity- the measure of the rate and extent of change in species along a gradient from

one habitat to others and

(c) y diversity- the richness in species of a range of a habitats in a geographical area which

is a consequence of the a diversity of the habitats together with the extent of the (3 diversity

between them

Shannon index is one of several diversity indices used to measure diversity in categorical data

According to Krebs (1999) Shannon index is used for rare species while Simpson index is used

which emphasize the common species The advantage of Shannon index is it takes into account

the number of species and the evenness of the species index is increased either by having

additional unique species or by having better species evenness The Shannon index is the

measure of infonnation content should be used only on random samples drawn from a large

community in which the total number of species is known (Krebs 1999)

3

Shannon index is the most popular measures of the species diversity which based on infonnation

theory According to Krebs (1999) there are four types of infonnation that might be collected

regarding order in the community

(8) The number of species

(b) The number of individuals in each species

(c) The places occupied by individuals of each species and

(d) The places occupied by the individuals as separate individuals

Simpson index also been used to quantify species diversity of small mammals derived by

Simpson (1943) The basis of this index is the probability of two individuals being conspecifics

Here Simpsons Reciprocal Index (110) is used where the values start 1 ([owest possible

figures) and it represents a community containing only one species to the maximum number

which represent the total number of species caught

According to Lande (1996) the species richness Shannon infonnation and Simpson diversity are

the most commonly used nonparametric measures of species diversity The proportion of the total

diversity found within communities provides a natural measure of similarity among multiple

communities The expected similarity among multiple random samples from the same depends

on the number of samples and on the underlying measures of diversity Measures of species

divers~ play a central role in ecology and conservation biology which giving the number of

species composition and the abundance of animals at the particular area

13 Species Similarity

Krebs (1999) noted that resemblance measure can be expressed either (a) similarity degree of

resemblance or (b) dissimilarity degree of difference Magurran (2004) stated that similarity or

dissimilarity indices provide quantitative bases of assessment in comparing species composition

and biodiversity of two or more assemblages in taxonomic and ecological research Krebs (1999)

stated that we need to use similarity coefficients or similarity indices that give some measure of

the relative abundance of each species in the two samples if we are dealing to quantify the

similarity oftwo such samples or community

Similarity matrix is the opposite concept to the distance matrix The elements of a similarity

matrix measure pairwise similarities of objects The greater similarity of two objects will

produced the high value of the measure Each similarity measures has its own properties and

generally gives different perspectives of the data turning the matter of choice not trivial

(Laurenco et al 2004)

According to Boyce and Ellison (2001) and Krebs (1999) similarity indices can be divided into

two major classes first is those that include joint absences or zero-zero matches (species that are

in neither of the two samples for which a similarity is being computed but are present in at least

one other plot in the study) and second class is those that do not include the zero-zero matches

CHAPTER ONE

Introduction

11 General Introduction

Ecological studies can be divided into two components extensive studies and intensive studies

According to Southwood and Henderson (2000) extensive studies frequently carried out to

present an infonnation on distribution and abundance for supplementary conservation and

management program in which the samples area are much larger than intensive studies Intensive

studies generate infonnation about the spatial pattern of populations and it is often possible to

relay the level of the population to oceanographic or climatic factors (Southwood amp Henderson

2000) In many communities studies ecologists acquire a list of the species composition that

occurs in each of several communities and if the quantitative sampling has been conducted some

measure of the relative abundance of each species (Krebs 1999)

Mostly research which been carried out is more focused on species diversity only and just a little

previous tudy been done to quantify the species similarity in addition to species diversity

Quantifying similarity and diversity of animals in tenn of species composition and abundance

will provide useful information about the population of the animal species at the particular study

sites (Magurran 2004)

Species similarity signify the similarity of each study or sample or sampling unit to each other

while the diversity of each unit to one another been signify as species diversity (Krebs 1999) It

is the intension of this study to address both species similarity and species diversity analysis

simultaneously on repetitive sampling of small mammals done on an open and closed habitat

12 Species Diversity

Krebs (1999) noted that a biological community has an attribute of species diversity and recently

there are many different ways have been suggested for measuring the species diversity Basically

it depends on the objective for the study conducted and the information that we want to see from

the samples collected Diversity measures require an estimate of species importance in the

community (Krebs 1999)

Species diversity for this aspect can be defined as the number of different species in a particular

area (species richness) weighted by some measure of abundance such as number of individuals or

biomass (Magurran 1998) Species evenness is part of the measures of species diversity which is

the relative abundance with which each species is represented in the particular area Species

evenness is a measure of biodiversity which qualifies how equal the community is numerically

Evenness is also a part of species diversity measure which compares the similarity of the

population size of each of the species present

Species richness and species evenness are probably the most frequently used measures of the

total biodiversity of the region (Magurran 1998 2004) Species richness noted that the observed

2

species number increases non-linearly with sampling effort Species richness and evenness are

component of biodiversity that mayor may not be correlated with one another and with pattern of

species abundance Gotelli and Colwell (2001) stated that standardising by the number of

individual collected and standardising by area or sampling effort can lead to the different

conclusions regarding species richness

According to Southwood and Henderson (2000) diversity can be divided into three categories

(a) a diversity- the diversity of species within a community or habitat

(b) f3 diversity- the measure of the rate and extent of change in species along a gradient from

one habitat to others and

(c) y diversity- the richness in species of a range of a habitats in a geographical area which

is a consequence of the a diversity of the habitats together with the extent of the (3 diversity

between them

Shannon index is one of several diversity indices used to measure diversity in categorical data

According to Krebs (1999) Shannon index is used for rare species while Simpson index is used

which emphasize the common species The advantage of Shannon index is it takes into account

the number of species and the evenness of the species index is increased either by having

additional unique species or by having better species evenness The Shannon index is the

measure of infonnation content should be used only on random samples drawn from a large

community in which the total number of species is known (Krebs 1999)

3

Shannon index is the most popular measures of the species diversity which based on infonnation

theory According to Krebs (1999) there are four types of infonnation that might be collected

regarding order in the community

(8) The number of species

(b) The number of individuals in each species

(c) The places occupied by individuals of each species and

(d) The places occupied by the individuals as separate individuals

Simpson index also been used to quantify species diversity of small mammals derived by

Simpson (1943) The basis of this index is the probability of two individuals being conspecifics

Here Simpsons Reciprocal Index (110) is used where the values start 1 ([owest possible

figures) and it represents a community containing only one species to the maximum number

which represent the total number of species caught

According to Lande (1996) the species richness Shannon infonnation and Simpson diversity are

the most commonly used nonparametric measures of species diversity The proportion of the total

diversity found within communities provides a natural measure of similarity among multiple

communities The expected similarity among multiple random samples from the same depends

on the number of samples and on the underlying measures of diversity Measures of species

divers~ play a central role in ecology and conservation biology which giving the number of

species composition and the abundance of animals at the particular area

CHAPTER ONE

Introduction

11 General Introduction

Ecological studies can be divided into two components extensive studies and intensive studies

According to Southwood and Henderson (2000) extensive studies frequently carried out to

present an infonnation on distribution and abundance for supplementary conservation and

management program in which the samples area are much larger than intensive studies Intensive

studies generate infonnation about the spatial pattern of populations and it is often possible to

relay the level of the population to oceanographic or climatic factors (Southwood amp Henderson

2000) In many communities studies ecologists acquire a list of the species composition that

occurs in each of several communities and if the quantitative sampling has been conducted some

measure of the relative abundance of each species (Krebs 1999)

Mostly research which been carried out is more focused on species diversity only and just a little

previous tudy been done to quantify the species similarity in addition to species diversity

Quantifying similarity and diversity of animals in tenn of species composition and abundance

will provide useful information about the population of the animal species at the particular study

sites (Magurran 2004)

Species similarity signify the similarity of each study or sample or sampling unit to each other

while the diversity of each unit to one another been signify as species diversity (Krebs 1999) It

is the intension of this study to address both species similarity and species diversity analysis

simultaneously on repetitive sampling of small mammals done on an open and closed habitat

12 Species Diversity

Krebs (1999) noted that a biological community has an attribute of species diversity and recently

there are many different ways have been suggested for measuring the species diversity Basically

it depends on the objective for the study conducted and the information that we want to see from

the samples collected Diversity measures require an estimate of species importance in the

community (Krebs 1999)

Species diversity for this aspect can be defined as the number of different species in a particular

area (species richness) weighted by some measure of abundance such as number of individuals or

biomass (Magurran 1998) Species evenness is part of the measures of species diversity which is

the relative abundance with which each species is represented in the particular area Species

evenness is a measure of biodiversity which qualifies how equal the community is numerically

Evenness is also a part of species diversity measure which compares the similarity of the

population size of each of the species present

Species richness and species evenness are probably the most frequently used measures of the

total biodiversity of the region (Magurran 1998 2004) Species richness noted that the observed

2

species number increases non-linearly with sampling effort Species richness and evenness are

component of biodiversity that mayor may not be correlated with one another and with pattern of

species abundance Gotelli and Colwell (2001) stated that standardising by the number of

individual collected and standardising by area or sampling effort can lead to the different

conclusions regarding species richness

According to Southwood and Henderson (2000) diversity can be divided into three categories

(a) a diversity- the diversity of species within a community or habitat

(b) f3 diversity- the measure of the rate and extent of change in species along a gradient from

one habitat to others and

(c) y diversity- the richness in species of a range of a habitats in a geographical area which

is a consequence of the a diversity of the habitats together with the extent of the (3 diversity

between them

Shannon index is one of several diversity indices used to measure diversity in categorical data

According to Krebs (1999) Shannon index is used for rare species while Simpson index is used

which emphasize the common species The advantage of Shannon index is it takes into account

the number of species and the evenness of the species index is increased either by having

additional unique species or by having better species evenness The Shannon index is the

measure of infonnation content should be used only on random samples drawn from a large

community in which the total number of species is known (Krebs 1999)

3

Shannon index is the most popular measures of the species diversity which based on infonnation

theory According to Krebs (1999) there are four types of infonnation that might be collected

regarding order in the community

(8) The number of species

(b) The number of individuals in each species

(c) The places occupied by individuals of each species and

(d) The places occupied by the individuals as separate individuals

Simpson index also been used to quantify species diversity of small mammals derived by

Simpson (1943) The basis of this index is the probability of two individuals being conspecifics

Here Simpsons Reciprocal Index (110) is used where the values start 1 ([owest possible

figures) and it represents a community containing only one species to the maximum number

which represent the total number of species caught

According to Lande (1996) the species richness Shannon infonnation and Simpson diversity are

the most commonly used nonparametric measures of species diversity The proportion of the total

diversity found within communities provides a natural measure of similarity among multiple

communities The expected similarity among multiple random samples from the same depends

on the number of samples and on the underlying measures of diversity Measures of species

divers~ play a central role in ecology and conservation biology which giving the number of

species composition and the abundance of animals at the particular area

13 Species Similarity

Krebs (1999) noted that resemblance measure can be expressed either (a) similarity degree of

resemblance or (b) dissimilarity degree of difference Magurran (2004) stated that similarity or

dissimilarity indices provide quantitative bases of assessment in comparing species composition

and biodiversity of two or more assemblages in taxonomic and ecological research Krebs (1999)

stated that we need to use similarity coefficients or similarity indices that give some measure of

the relative abundance of each species in the two samples if we are dealing to quantify the

similarity oftwo such samples or community

Similarity matrix is the opposite concept to the distance matrix The elements of a similarity

matrix measure pairwise similarities of objects The greater similarity of two objects will

produced the high value of the measure Each similarity measures has its own properties and

generally gives different perspectives of the data turning the matter of choice not trivial

(Laurenco et al 2004)

According to Boyce and Ellison (2001) and Krebs (1999) similarity indices can be divided into

two major classes first is those that include joint absences or zero-zero matches (species that are

in neither of the two samples for which a similarity is being computed but are present in at least

one other plot in the study) and second class is those that do not include the zero-zero matches

studies generate infonnation about the spatial pattern of populations and it is often possible to

relay the level of the population to oceanographic or climatic factors (Southwood amp Henderson

2000) In many communities studies ecologists acquire a list of the species composition that

occurs in each of several communities and if the quantitative sampling has been conducted some

measure of the relative abundance of each species (Krebs 1999)

Mostly research which been carried out is more focused on species diversity only and just a little

previous tudy been done to quantify the species similarity in addition to species diversity

Quantifying similarity and diversity of animals in tenn of species composition and abundance

will provide useful information about the population of the animal species at the particular study

sites (Magurran 2004)

Species similarity signify the similarity of each study or sample or sampling unit to each other

while the diversity of each unit to one another been signify as species diversity (Krebs 1999) It

is the intension of this study to address both species similarity and species diversity analysis

simultaneously on repetitive sampling of small mammals done on an open and closed habitat

12 Species Diversity

Krebs (1999) noted that a biological community has an attribute of species diversity and recently

there are many different ways have been suggested for measuring the species diversity Basically

it depends on the objective for the study conducted and the information that we want to see from

the samples collected Diversity measures require an estimate of species importance in the

community (Krebs 1999)

Species diversity for this aspect can be defined as the number of different species in a particular

area (species richness) weighted by some measure of abundance such as number of individuals or

biomass (Magurran 1998) Species evenness is part of the measures of species diversity which is

the relative abundance with which each species is represented in the particular area Species

evenness is a measure of biodiversity which qualifies how equal the community is numerically

Evenness is also a part of species diversity measure which compares the similarity of the

population size of each of the species present

Species richness and species evenness are probably the most frequently used measures of the

total biodiversity of the region (Magurran 1998 2004) Species richness noted that the observed

2

species number increases non-linearly with sampling effort Species richness and evenness are

component of biodiversity that mayor may not be correlated with one another and with pattern of

species abundance Gotelli and Colwell (2001) stated that standardising by the number of

individual collected and standardising by area or sampling effort can lead to the different

conclusions regarding species richness

According to Southwood and Henderson (2000) diversity can be divided into three categories

(a) a diversity- the diversity of species within a community or habitat

(b) f3 diversity- the measure of the rate and extent of change in species along a gradient from

one habitat to others and

(c) y diversity- the richness in species of a range of a habitats in a geographical area which

is a consequence of the a diversity of the habitats together with the extent of the (3 diversity

between them

Shannon index is one of several diversity indices used to measure diversity in categorical data

According to Krebs (1999) Shannon index is used for rare species while Simpson index is used

which emphasize the common species The advantage of Shannon index is it takes into account

the number of species and the evenness of the species index is increased either by having

additional unique species or by having better species evenness The Shannon index is the

measure of infonnation content should be used only on random samples drawn from a large

community in which the total number of species is known (Krebs 1999)

3

Shannon index is the most popular measures of the species diversity which based on infonnation

theory According to Krebs (1999) there are four types of infonnation that might be collected

regarding order in the community

(8) The number of species

(b) The number of individuals in each species

(c) The places occupied by individuals of each species and

(d) The places occupied by the individuals as separate individuals

Simpson index also been used to quantify species diversity of small mammals derived by

Simpson (1943) The basis of this index is the probability of two individuals being conspecifics

Here Simpsons Reciprocal Index (110) is used where the values start 1 ([owest possible

figures) and it represents a community containing only one species to the maximum number

which represent the total number of species caught

According to Lande (1996) the species richness Shannon infonnation and Simpson diversity are

the most commonly used nonparametric measures of species diversity The proportion of the total

diversity found within communities provides a natural measure of similarity among multiple

communities The expected similarity among multiple random samples from the same depends

on the number of samples and on the underlying measures of diversity Measures of species

divers~ play a central role in ecology and conservation biology which giving the number of

species composition and the abundance of animals at the particular area

13 Species Similarity

Krebs (1999) noted that resemblance measure can be expressed either (a) similarity degree of

resemblance or (b) dissimilarity degree of difference Magurran (2004) stated that similarity or

dissimilarity indices provide quantitative bases of assessment in comparing species composition

and biodiversity of two or more assemblages in taxonomic and ecological research Krebs (1999)

stated that we need to use similarity coefficients or similarity indices that give some measure of

the relative abundance of each species in the two samples if we are dealing to quantify the

similarity oftwo such samples or community

Similarity matrix is the opposite concept to the distance matrix The elements of a similarity

matrix measure pairwise similarities of objects The greater similarity of two objects will

produced the high value of the measure Each similarity measures has its own properties and

generally gives different perspectives of the data turning the matter of choice not trivial

(Laurenco et al 2004)

According to Boyce and Ellison (2001) and Krebs (1999) similarity indices can be divided into

two major classes first is those that include joint absences or zero-zero matches (species that are

in neither of the two samples for which a similarity is being computed but are present in at least

one other plot in the study) and second class is those that do not include the zero-zero matches

11 General Introduction

CHAPTER ONE

Introduction

11 General Introduction

Ecological studies can be divided into two components extensive studies and intensive studies

According to Southwood and Henderson (2000) extensive studies frequently carried out to

present an infonnation on distribution and abundance for supplementary conservation and

management program in which the samples area are much larger than intensive studies Intensive

studies generate infonnation about the spatial pattern of populations and it is often possible to

relay the level of the population to oceanographic or climatic factors (Southwood amp Henderson

2000) In many communities studies ecologists acquire a list of the species composition that

occurs in each of several communities and if the quantitative sampling has been conducted some

measure of the relative abundance of each species (Krebs 1999)

Mostly research which been carried out is more focused on species diversity only and just a little

previous tudy been done to quantify the species similarity in addition to species diversity

Quantifying similarity and diversity of animals in tenn of species composition and abundance

will provide useful information about the population of the animal species at the particular study

sites (Magurran 2004)

Species similarity signify the similarity of each study or sample or sampling unit to each other

while the diversity of each unit to one another been signify as species diversity (Krebs 1999) It

is the intension of this study to address both species similarity and species diversity analysis

simultaneously on repetitive sampling of small mammals done on an open and closed habitat

12 Species Diversity

Krebs (1999) noted that a biological community has an attribute of species diversity and recently

there are many different ways have been suggested for measuring the species diversity Basically

it depends on the objective for the study conducted and the information that we want to see from

the samples collected Diversity measures require an estimate of species importance in the

community (Krebs 1999)

Species diversity for this aspect can be defined as the number of different species in a particular

area (species richness) weighted by some measure of abundance such as number of individuals or

biomass (Magurran 1998) Species evenness is part of the measures of species diversity which is

the relative abundance with which each species is represented in the particular area Species

evenness is a measure of biodiversity which qualifies how equal the community is numerically

Evenness is also a part of species diversity measure which compares the similarity of the

population size of each of the species present

Species richness and species evenness are probably the most frequently used measures of the

total biodiversity of the region (Magurran 1998 2004) Species richness noted that the observed

2

species number increases non-linearly with sampling effort Species richness and evenness are

component of biodiversity that mayor may not be correlated with one another and with pattern of

species abundance Gotelli and Colwell (2001) stated that standardising by the number of

individual collected and standardising by area or sampling effort can lead to the different

conclusions regarding species richness

According to Southwood and Henderson (2000) diversity can be divided into three categories

(a) a diversity- the diversity of species within a community or habitat

(b) f3 diversity- the measure of the rate and extent of change in species along a gradient from

one habitat to others and

(c) y diversity- the richness in species of a range of a habitats in a geographical area which

is a consequence of the a diversity of the habitats together with the extent of the (3 diversity

between them

Shannon index is one of several diversity indices used to measure diversity in categorical data

According to Krebs (1999) Shannon index is used for rare species while Simpson index is used

which emphasize the common species The advantage of Shannon index is it takes into account

the number of species and the evenness of the species index is increased either by having

additional unique species or by having better species evenness The Shannon index is the

measure of infonnation content should be used only on random samples drawn from a large

community in which the total number of species is known (Krebs 1999)

3

Shannon index is the most popular measures of the species diversity which based on infonnation

theory According to Krebs (1999) there are four types of infonnation that might be collected

regarding order in the community

(8) The number of species

(b) The number of individuals in each species

(c) The places occupied by individuals of each species and

(d) The places occupied by the individuals as separate individuals

Simpson index also been used to quantify species diversity of small mammals derived by

Simpson (1943) The basis of this index is the probability of two individuals being conspecifics

Here Simpsons Reciprocal Index (110) is used where the values start 1 ([owest possible

figures) and it represents a community containing only one species to the maximum number

which represent the total number of species caught

According to Lande (1996) the species richness Shannon infonnation and Simpson diversity are

the most commonly used nonparametric measures of species diversity The proportion of the total

diversity found within communities provides a natural measure of similarity among multiple

communities The expected similarity among multiple random samples from the same depends

on the number of samples and on the underlying measures of diversity Measures of species

divers~ play a central role in ecology and conservation biology which giving the number of

species composition and the abundance of animals at the particular area

13 Species Similarity

Krebs (1999) noted that resemblance measure can be expressed either (a) similarity degree of

resemblance or (b) dissimilarity degree of difference Magurran (2004) stated that similarity or

dissimilarity indices provide quantitative bases of assessment in comparing species composition

and biodiversity of two or more assemblages in taxonomic and ecological research Krebs (1999)

stated that we need to use similarity coefficients or similarity indices that give some measure of

the relative abundance of each species in the two samples if we are dealing to quantify the

similarity oftwo such samples or community

Similarity matrix is the opposite concept to the distance matrix The elements of a similarity

matrix measure pairwise similarities of objects The greater similarity of two objects will

produced the high value of the measure Each similarity measures has its own properties and

generally gives different perspectives of the data turning the matter of choice not trivial

(Laurenco et al 2004)

According to Boyce and Ellison (2001) and Krebs (1999) similarity indices can be divided into

two major classes first is those that include joint absences or zero-zero matches (species that are

in neither of the two samples for which a similarity is being computed but are present in at least

one other plot in the study) and second class is those that do not include the zero-zero matches

11 General Introduction

Ecological studies can be divided into two components extensive studies and intensive studies

According to Southwood and Henderson (2000) extensive studies frequently carried out to

present an infonnation on distribution and abundance for supplementary conservation and

management program in which the samples area are much larger than intensive studies Intensive

studies generate infonnation about the spatial pattern of populations and it is often possible to

relay the level of the population to oceanographic or climatic factors (Southwood amp Henderson

2000) In many communities studies ecologists acquire a list of the species composition that

occurs in each of several communities and if the quantitative sampling has been conducted some

measure of the relative abundance of each species (Krebs 1999)

Mostly research which been carried out is more focused on species diversity only and just a little

previous tudy been done to quantify the species similarity in addition to species diversity

Quantifying similarity and diversity of animals in tenn of species composition and abundance

will provide useful information about the population of the animal species at the particular study

sites (Magurran 2004)

Species similarity signify the similarity of each study or sample or sampling unit to each other

while the diversity of each unit to one another been signify as species diversity (Krebs 1999) It

is the intension of this study to address both species similarity and species diversity analysis

simultaneously on repetitive sampling of small mammals done on an open and closed habitat

12 Species Diversity

Krebs (1999) noted that a biological community has an attribute of species diversity and recently

there are many different ways have been suggested for measuring the species diversity Basically

it depends on the objective for the study conducted and the information that we want to see from

the samples collected Diversity measures require an estimate of species importance in the

community (Krebs 1999)

Species diversity for this aspect can be defined as the number of different species in a particular

area (species richness) weighted by some measure of abundance such as number of individuals or

biomass (Magurran 1998) Species evenness is part of the measures of species diversity which is

the relative abundance with which each species is represented in the particular area Species

evenness is a measure of biodiversity which qualifies how equal the community is numerically

Evenness is also a part of species diversity measure which compares the similarity of the

population size of each of the species present

Species richness and species evenness are probably the most frequently used measures of the

total biodiversity of the region (Magurran 1998 2004) Species richness noted that the observed

2

species number increases non-linearly with sampling effort Species richness and evenness are

component of biodiversity that mayor may not be correlated with one another and with pattern of

species abundance Gotelli and Colwell (2001) stated that standardising by the number of

individual collected and standardising by area or sampling effort can lead to the different

conclusions regarding species richness

According to Southwood and Henderson (2000) diversity can be divided into three categories

(a) a diversity- the diversity of species within a community or habitat

(b) f3 diversity- the measure of the rate and extent of change in species along a gradient from

one habitat to others and

(c) y diversity- the richness in species of a range of a habitats in a geographical area which

is a consequence of the a diversity of the habitats together with the extent of the (3 diversity

between them

Shannon index is one of several diversity indices used to measure diversity in categorical data

According to Krebs (1999) Shannon index is used for rare species while Simpson index is used

which emphasize the common species The advantage of Shannon index is it takes into account

the number of species and the evenness of the species index is increased either by having

additional unique species or by having better species evenness The Shannon index is the

measure of infonnation content should be used only on random samples drawn from a large

community in which the total number of species is known (Krebs 1999)

Shannon index is the most popular measures of the species diversity which based on infonnation

theory According to Krebs (1999) there are four types of infonnation that might be collected

regarding order in the community

(8) The number of species

(b) The number of individuals in each species

(c) The places occupied by individuals of each species and

(d) The places occupied by the individuals as separate individuals

Simpson index also been used to quantify species diversity of small mammals derived by

Simpson (1943) The basis of this index is the probability of two individuals being conspecifics

Here Simpsons Reciprocal Index (110) is used where the values start 1 ([owest possible

figures) and it represents a community containing only one species to the maximum number

which represent the total number of species caught

According to Lande (1996) the species richness Shannon infonnation and Simpson diversity are

the most commonly used nonparametric measures of species diversity The proportion of the total

diversity found within communities provides a natural measure of similarity among multiple

communities The expected similarity among multiple random samples from the same depends

on the number of samples and on the underlying measures of diversity Measures of species

divers~ play a central role in ecology and conservation biology which giving the number of

species composition and the abundance of animals at the particular area

stated that we need to use similarity coefficients or similarity indices that give some measure of

Similarity matrix is the opposite concept to the distance matrix The elements of a similarity

matrix measure pairwise similarities of objects The greater similarity of two objects will

produced the high value of the measure Each similarity measures has its own properties and

generally gives different perspectives of the data turning the matter of choice not trivial

According to Boyce and Ellison (2001) and Krebs (1999) similarity indices can be divided into

two major classes first is those that include joint absences or zero-zero matches (species that are

in neither of the two samples for which a similarity is being computed but are present in at least

Introduction

11 General Introduction

Ecological studies can be divided into two components extensive studies and intensive studies

According to Southwood and Henderson (2000) extensive studies frequently carried out to

present an infonnation on distribution and abundance for supplementary conservation and

management program in which the samples area are much larger than intensive studies Intensive

studies generate infonnation about the spatial pattern of populations and it is often possible to

relay the level of the population to oceanographic or climatic factors (Southwood amp Henderson

2000) In many communities studies ecologists acquire a list of the species composition that

occurs in each of several communities and if the quantitative sampling has been conducted some

measure of the relative abundance of each species (Krebs 1999)

Mostly research which been carried out is more focused on species diversity only and just a little

previous tudy been done to quantify the species similarity in addition to species diversity

Quantifying similarity and diversity of animals in tenn of species composition and abundance

will provide useful information about the population of the animal species at the particular study

sites (Magurran 2004)

Species similarity signify the similarity of each study or sample or sampling unit to each other

while the diversity of each unit to one another been signify as species diversity (Krebs 1999) It

is the intension of this study to address both species similarity and species diversity analysis

simultaneously on repetitive sampling of small mammals done on an open and closed habitat

12 Species Diversity

Krebs (1999) noted that a biological community has an attribute of species diversity and recently

there are many different ways have been suggested for measuring the species diversity Basically

it depends on the objective for the study conducted and the information that we want to see from

the samples collected Diversity measures require an estimate of species importance in the

community (Krebs 1999)

Species diversity for this aspect can be defined as the number of different species in a particular

area (species richness) weighted by some measure of abundance such as number of individuals or

biomass (Magurran 1998) Species evenness is part of the measures of species diversity which is

the relative abundance with which each species is represented in the particular area Species

evenness is a measure of biodiversity which qualifies how equal the community is numerically

Evenness is also a part of species diversity measure which compares the similarity of the

population size of each of the species present

Species richness and species evenness are probably the most frequently used measures of the

total biodiversity of the region (Magurran 1998 2004) Species richness noted that the observed

2

species number increases non-linearly with sampling effort Species richness and evenness are

component of biodiversity that mayor may not be correlated with one another and with pattern of

species abundance Gotelli and Colwell (2001) stated that standardising by the number of

individual collected and standardising by area or sampling effort can lead to the different

conclusions regarding species richness

According to Southwood and Henderson (2000) diversity can be divided into three categories

(a) a diversity- the diversity of species within a community or habitat

(b) f3 diversity- the measure of the rate and extent of change in species along a gradient from

one habitat to others and

(c) y diversity- the richness in species of a range of a habitats in a geographical area which

is a consequence of the a diversity of the habitats together with the extent of the (3 diversity

between them

Shannon index is one of several diversity indices used to measure diversity in categorical data

According to Krebs (1999) Shannon index is used for rare species while Simpson index is used

which emphasize the common species The advantage of Shannon index is it takes into account

the number of species and the evenness of the species index is increased either by having

additional unique species or by having better species evenness The Shannon index is the

measure of infonnation content should be used only on random samples drawn from a large

community in which the total number of species is known (Krebs 1999)

3

Shannon index is the most popular measures of the species diversity which based on infonnation

theory According to Krebs (1999) there are four types of infonnation that might be collected

regarding order in the community

(8) The number of species

(b) The number of individuals in each species

(c) The places occupied by individuals of each species and

(d) The places occupied by the individuals as separate individuals

Simpson index also been used to quantify species diversity of small mammals derived by

Simpson (1943) The basis of this index is the probability of two individuals being conspecifics

Here Simpsons Reciprocal Index (110) is used where the values start 1 ([owest possible

figures) and it represents a community containing only one species to the maximum number

which represent the total number of species caught

According to Lande (1996) the species richness Shannon infonnation and Simpson diversity are

the most commonly used nonparametric measures of species diversity The proportion of the total

diversity found within communities provides a natural measure of similarity among multiple

communities The expected similarity among multiple random samples from the same depends

on the number of samples and on the underlying measures of diversity Measures of species

divers~ play a central role in ecology and conservation biology which giving the number of

species composition and the abundance of animals at the particular area

13 Species Similarity

Krebs (1999) noted that resemblance measure can be expressed either (a) similarity degree of

resemblance or (b) dissimilarity degree of difference Magurran (2004) stated that similarity or

dissimilarity indices provide quantitative bases of assessment in comparing species composition

and biodiversity of two or more assemblages in taxonomic and ecological research Krebs (1999)

stated that we need to use similarity coefficients or similarity indices that give some measure of

the relative abundance of each species in the two samples if we are dealing to quantify the

similarity oftwo such samples or community

Similarity matrix is the opposite concept to the distance matrix The elements of a similarity

matrix measure pairwise similarities of objects The greater similarity of two objects will

produced the high value of the measure Each similarity measures has its own properties and

generally gives different perspectives of the data turning the matter of choice not trivial

(Laurenco et al 2004)

According to Boyce and Ellison (2001) and Krebs (1999) similarity indices can be divided into

two major classes first is those that include joint absences or zero-zero matches (species that are

in neither of the two samples for which a similarity is being computed but are present in at least

one other plot in the study) and second class is those that do not include the zero-zero matches

produced the high value of the measure Each similarity measures has its own properties and

generally gives different perspectives of the data turning the matter of choice not trivial

(Laurenco et al 2004)

According to Boyce and Ellison (2001) and Krebs (1999) similarity indices can be divided into

two major classes first is those that include joint absences or zero-zero matches (species that are

in neither of the two samples for which a similarity is being computed but are present in at least

one other plot in the study) and second class is those that do not include the zero-zero matches
