Different types of mutualisms

(Trophic mutualisms) Examples?
2. Those involving defense(Defensive mutualisms) Examples?

Community: an association of populations of
different species living in a particular area
Community ecology: focus is understanding the
diversity and relative abundance of species in
the community

Questions asked by community ecologists
What determines the number of species in a community?
How does disturbance affect community structure?
Does adding new species change the way a community functions?

Communities
What is a community?
How are communities described?
How are species organizedwithin a community?
How do communities change over time and space?

How are communities described?
number of species = species richness
evenness = # individuals/species
diversity = richness and evenness
relative abundance

What determines diversity of a community?
1. diversity is related to area
2. diversity is related to variability
Lots of other theories that attempt to explain controls on diversity

Hard to separate variability and area - typically larger areas have more habitat variability
Lesser Antilles – island size and habitat diversity vary independently
- two kinds of islands- tall volcanic – diverse habitats- low raised seabed – 1 habitat
- both kinds of islands come in all sizes

Suppose there are 3 species in a community,
species A, B, and C. When you remove
species A from the community, species C
goes extinct. What can you conclude
about the relationship between species?
a. Species A is a predator of species B.
b. Species A is a prey of species C.
c. Species B is a competitor of species C.
d. All of these are possible.
