SEPTEMBER SPEAKER REVIEW

Michele Stillinger, MHS member was our guest speaker at the September meeting. Earlier this year Michele had the opportunity to visit the Oklahoma City Zoo and was privileged enough to provided access to the curator and the behind the scenes of the Reptile House. These experiences she shared with the MHS membership. Michele prefaced her talk with a bit of history on the building that is now the Reptile House. Previous to that the building was referred to as the "Snake Pit". Rather than do a quick photo essay on all the herps in residence, Michele focused primarily on the Chameleons and Tropical Frogs.

In the Chameleon family Michele explained how all the animals were kept in naturalistic vivarium setups. Of the Chameleons the Zoo so far has had success with breeding the Parson's, Jackson's, Flapneck's, Knsna Dwarf and a variety of others. She topped off that portion of her talk with an absolutely stunning photograph of a seven month old Oustaleti Chameleon with a newborn perched directly above it.

Michele then touched upon some of the serpents he was working with. Particularly interesting was the beautiful color morphs of the Emerald Tree Boa.

Next she moved onto the Tropical frogs. The Zoo has so far bred the Dendrobates Azureus, the Dying Frog, and the Red-Eyed Tree Frog. One of the strategies they use is to place an inverted buttercup with a lid attached inside the enclosures. A small door is cut, in which the frogs enter and lay eggs. After the eggs hatch on the lids (approximately seven days), the lids are then removed with the tadpoles. They are then floated in individual trays in a filtered aquarium. In about two months they metamorphose into tiny frogs.

Michele ended her talk with more stunning photography of a most photogenic subject ---- The Red-Eyed Tree Frog.

All of us in MHS should be thankful to Michele for all her preparation and hard work to bring us a very educational and visually stimulating evening.

REFRESHMENTS

For September's meeting Toni Jesmer brought muffins and rolls. THANKS TONI!!! The Donation Frog received $15.03 in September. If you'd like to help provide treats for a meeting please talk to Candy Ashbach or Nanette Jimerson at the meeting to find out about what's needed.

CRITTER OF THE MONTH

The critter of the month was "Your South American Herp". The critters and their keepers were:

Ted Meissner - Common Boa John Meltzer - Budgett's Frog Jeff LeClere and Theresa Kollander - Common Green Iguana Fred Bosman - Guyana Red-tail Boa

1992 STATE FAIR

The 1992 State Fair Exhibit was reduced from last year due to the lack of new space. The original exhibit had to be moved because of a safety concern due to the electrical panels behind the exhibit.

The 1992 State Exhibit consisted of Minnesota turtles. They were located on the east end of the fish tanks. The turtles were provided by Gary Ash (softshell and map turtle), Bell Museum (Blanding's turtle), John Moriarty (wood turtle), Dave Norman (painted turtle) and Springbrook Nature Center (snapping turtle). Thank you to all that helped by supplying.

There were a number of inquiries on the absence of the snakes. The DNR will find space for next year. The exhibit will be at the west end of the fish exhibit.

THANKS A BUNDLE By

Marilyn Brooks

I may sometimes forget to say THANKS to you each month after Newsletter Folding, but that doesn't mean I don't appreciate your effort. It may seem like you don't do that much, but each person keeps the Newsletter going down the line until it's bundled and ready for the Post Office. Or maybe it is the great conversations that make you forget your "working". I just want you to know your time and energy is noticed. Thank you to the following people who put in the time in first half of this year:

Jim Alred Sally Brewer Todd Cherveny Dennis Daly Bruce Haig Cindy Hardy Greg Kvanbek John Levell Ann Porwoll Jim, Karin, Siri

and Josie Rea

Lest we not forget the contribution of Delvin Jones for having labels printed, even under extreme circumstances. Thank you.

HELP! ! ! !

The Minnesota Herpetological Society needs a volunteer to maintain the Nametag Box at the meetings. It basically entails removing expired nametags, putting new tags in badges, sorting and helping people find nametags. It doesn't require a lot time, just a couple of minutes before and after the meeting. If you are interested, please contact one of the Board members.

REPTILE CLASSIFICATION PART ONE: INTRODUCTION

BY JOHN P. LEVELL

At the August 7th (1992) meeting of the Minnesota Herpetological Society, we were fortunate to have as our guest speaker, Jon Kramer of the Potomac Museum Group. The topic of Jon's talk was the Ancient Age of Reptiles. As can be expected the presentation was most interesting, covering many various different types of reptiles that existed in the past. Naturally Dinosaurs figured prominently in this program.

During the Q&A session following the program, a question was raised regarding the relationship of Dinosaurs to other reptile groups. It was the opinion our speaker, that Dinosaurs are not reptiles, but rather be placed in the class of Aves (birds). To support this viewpoint, Jon pointed out some of the unique features that set Dinosaurs apart from the other reptile orders. While this theory is quite interesting, and while I don't necessarily disagree with it, what wasn't pointed out (thru no fault of Jon's) is the fact that uniqueness is not all that unusual in the class of

. Reptilia. A few reptile orders other than the Dinosaurs, have produced forms unlike any other reptile group, and one order, Testudinata (the turtles), has accomplished a feat totally unique among any vertebrate group before or since. We will explore these subjects more later.

This in turn led to a discussion of the classification of the reptiles in general. Different opinions were presented on this subject, among them the artificial or vague nature of the system used to classify reptiles. Here I feel I must point out that the term Dinosaur, or more properly Dinosauria, is as artificial as any, actually encompassing two distinct reptilian orders. During the course of this discussion it became apparent that some misunderstanding of the classification systems exists.

With these thoughts in mind I thought it might be of interest to some readers to see what the current standard system of reptile classification looks like. I also feel it may be of interest to present the basics of classification and the reasons why the system is organized the way it is. While on the subject we may as well explore the various orders or reptiles, both living and extinct. Due to the length of this subject it will have to be presented in several parts. In this, part one, we will look at basic classification. Future installments of this series will cover reptile classification and the individual reptilian orders more fully.

The purpose of this series of articles is to present a starting point, a place to begin looking at the broad picture of the relationships of the one reptile group to another and to the interpretation of that picture. Remember that none of this is "set in stone" and that it isn't a condemnation of any of Jon Kramer's views. Disagreements among authorities of any subject are normal, healthy, and to be expected. It is in this way that our store of knowledge is increased.

Before going further we should realize that all classification systems are somewhat artificial. They are designed for the use of scientists to aid in the study of particular groups, and their relationships to other groups. What one authority accepts, another

The Minnesota Herpetological Society is asking your help in getting together a list of possible projects. These can be existing projects or new ideas. We are able to apply for Grants from Corporations and Government Agencies to fund such projects.

Projects need to show benefit to Members of MHS, to the General Public or to Reptiles and Amphibians. Projects might' be to research an animal, to work out a needed protection of an animal, to do a captive breeding and release, to expand a present MHS project, to help with someone else's existing project, to copy another organization's successful program, or others.

If you have an idea, we would like to hear it. The back side of this page is a form to put your idea in writing and mail to us. Please fill in as much as possible, the more information we have the better to review the project. It is not necessary to put your name and number, but we would like you to, as we can then 'call to clarify if we have any questions.

We have also provided a space for you to express any other questions, comments, or ideas you have for the Society. We want to hear from the members that make up MHS about ways to improve our Organization.

Please return this form by the middle of November, but suggestions (or forms) will be accepted at any time. All you need to do is fold this letter at the two lines, leaving the bottom showing. Please a stamp on the "X" and drop in the mail. We can not express how much your input will help us in expanding what we can accomplish to help reptiles and amphibians. _______________ _

may not. Also since our knowledge of any group is far from complete and since our new fossils of extinct forms are being discovered all the time, the system is in a state of constant flux. This inevitably leads to certain species or entire genera being shifted back and forth from one group to another. While this may sometimes prove confusing, we have to admit that some method of organizing groups must exist if any understanding of the relationship of one species or genus to another and their evolutionary history is ever to be achieved.

The current method to classify organisms is based on the system created by Carl Linnaeus in his work "Systema Naturae" 1758. In this classification system, organisms are arranged in a series of categories, each category less inclusive than the category preceding it. In this way kingdom is divided into phyla, phylum into classes, class into orders, order into families, family into genera, and genus into species. In addition several other divisions have been created such as subspecies, supraorder etc.

Thus a fairly complete classification of an animal we should all be familiar with, the corn snake, would look like this;

Kingdom: Phylum: Subphylum: Class: Subclass: Order: Suborder: Family: Subfamily: Genus: Species: Subspecies:

Animal Chordata Vertabrata Reptilia Lepidosauria Squamata Serpentes Colubridae Colubridae Elaphe Elaphe guttata Elaphe guttata guttata

As can be seen above each category becomes less inclusive as we progress down the list, so that when the bottom of the list is reacned we are dealing with one particular animal. The system also lets us organize the various groups into some semblance of order based upon their similarities or differences. For example it can be shown that the subspecies Elaphe guttata guttata would be more closely related to the subspecies Elaphe guttata emoryi (Great Plains Rats Snake) than it would to the species Elaphe obsoleta (Black Rat Snake). It can also be shown that E. g. guttata and E. o. obsoleta are more closely related to each other than either would be to a species from any other genus, and so on up the list.

This can probably best be illustrated by classifying two species from different genera, in this case we'll use the corn snake and another common species, the eastern kingsnake (Lampropeltis getula getula). That classification might look like this;

Class: Order: Suborder: Family: Genus: Species: Subspecies:

Reptilia Squamata Serpentes Colubridae a). Elaphe

guttata guttata

MRS NEWSLETIER VOLUME XII NUMBER 8

b) . Lampropeltis getula getula

PAGE 11

Page 16: Vol. 12 (1992), No. 9

By examining the above simplified classification, we can see that both species are reptiles, that they both belong to the order Squamata, suborder Serpentes, and family Colubridae. After that they are different enough from one another to be classified in different genera. We can also see that both belong to species with more than one recognized form, because of their subspecific designations. From here it can easily be imagined how entire genealogies can be built up by the addition of more information into individual categories. This will become more evident as we go along.

One last thing to point out is that the basic unit of this classification system is the species category. The category subspecies being merely a sub-division of species. In other words, while a family may contain several distinct genera, and a genus several distinct species, the species category is an entity onto it~elf. The only way it can be broken own further is by being sub-divided itself. For example;

Genus: Elaphe Species: guttata Subspecies: guttata

(Corn Snake) emoryi (Great Plains Rat Snake)

vulpina vulpina (Western Fox Snake) gloydi (Eastern Fox Snake)

As can be seen both guttata and vulpina have two recognized forms, different yet still related enough to be conside~ed the same species. Subspecies can freely interbreed with other members of their species in nature. Most species do not freely interbreed with other species under natural conditions.

Other than a few simple rules (which we can cover later), that about covers the basics of animal classification. Hopefully, I've succeeded in showing that the current classification system, de~pite it's faults, is still useful. I don't think much progress in our understanding of the compl~x relationships of organisms and their evolution, can be made without it.

In part two of this arti~le, we will look at the classification of reptiles more closely. Part Two will also include a checklist of the reptilian orders, both living and extinct, with brief summaries of each.

BOOK REVIEW By

Drew Newman

Title: The Care and Maintenance of Savannah Monitors and Other Popular Monitor Species.

Author: Michael Balasi Publisher: Advanced Vivarium Systems, Lakeside CA 1992

Anyone who has ever kept a monitor species knows quite well the scarcity of literature on husbandry. Many general herp books would devote a few pages to the genus Varanus, but not divulge much more than some statistics on range and distribution. I've even encountered a few books that would omit the animals entirely, on the premise that they were inappropriate for the private collection.

So earlier this year, I welcomed with great anticipation this latest edition to The Herpetocultural Library. If one is a varanophile, a simple glance at the bibliography will tell you this innocuous looking book is far removed from "Lizards as a New Pet" fare that is so common among herp literature.

The book is divided into eleven chapters and a bibliography. In the first two chapters the delves into the current C.I.T.E.S. status of Varanidae and give some background on distribution. He also imparts a little known fact that V. olivaceus is an omnivore.

With chapter three he focuses on particular information regarding the Savannah monitor. He describes the four subspecies, giving their ranges.

In the section on sexing, I have to take exception to his advice on using saline injections as it is presented in this book. I do not doubt that this can be a reliable indicator, but it frightens me that this piece of information will reach a majority of people, inept at such a practice. If his comments on this were prefaced with getting assistance with a herp vet or even someone experienced in subcutaneous injections on herps, I would feel more comfortable.

In discussing regulations in responsible Savannah monitor ownership, the author takes time to come forth with some very pertinent and timely ethical issues, which if adhered to, will benefit all of us involved in herpetoculture (this seems to be inherent in the other publications of The Herpetocultural Library---a trend that needs to be continued).

In "Selecting a Savannah Monitor" he gives an overview of the common protocol used to select a healthy animal. It may be redundant for those of us who have been around herps for a while, but information like this, is imperative for the beginner.

In the chapter on housing and general maintenance, cage size an escape are discussed thoroughly. Adult monitors are not animals which can comfortably be housed in aquaria with a screen top and most often custom cages need to be constructed. Dog kennels are mentioned (specifically modified) as an option for larger animals. (This reviewer has corresponded with people, who claim great success wi th using such an enclosure)., Two tips such as not using cedar as a bedding and never using a disinfectant compound such as Lysol, could pay for this book many times over in saved animals for someone who is not aware of the toxic properties of these products.

MHS NEWSLETIER VOLUME XII NUMBER 9 PAGE 13

Page 18: Vol. 12 (1992), No. 9

When discussing feeding of Savannah monitors he gives amounts and frequency by size of animal which is a very helpful criteria. It is also advised that if egg and chicken are to be offered, they should be cooked.

Under Savannah monitor personalities it is outlined very specifically that monitors can be formidable adversaries and should be handled with care. A severe bite, lash of the tail, or defecation shower are all possibilities when attempting to handle an angry or frightened animal.

When addressing diseases and disorders it is refreshing to see that the author has included a list of herp medical texts, by the likes of Ross, Frye, and others. He also mentions the use of carbaryl (seven) for ticks and mites, which I haven't seen advocated elsewhere. (His reference to the tick as "an obnoxious arachnid" gave me a good chuckle).

In the section on breeding a hypothetical model is presented with an emphasis that it may need much revision. Due to importation in large numbers the private sector has not embraced propagation of Varanids with the fervor that it has in some other reptile species. The author rightfully encourages us to develop a methodology that can lead to more frequent captive birth of this wonderful family of lizards.

The last chapter notes on other species should be of interests to those of us who have "graduated" to other monitors or at least maintained some of them in our collections. The information on V. salva~dorii is particularly interesting since this animal has recently been turning up on price lists and is rumored to be approaching appendix one status.

This book has thirty black and white photographs which all seem original. The only photograph which I feel could have been omitted is the one on the bottom of page six. Holding an adult monitor, no matter how tame, close to one's face could lead to an awful accident. Can anyone imagine something more horrible than getting bit in the face by a large lizard.

Overall this is an exceptional book. The information contained within is a type of data one would expect to find in a book, costing ten times as much and sandwiched between hundreds of glossy photographs. In closing I would like to reprint the address to Varanix, as it was included in the above mentioned text. Anyone with any degree of interest in monitors can benefit greatly from this organizations bi-monthly newsletter.

FROGTOWN GOES FROGGY

Residents, schools, churches and even businesses will try to leap into the Guinness Book of World records on Sept. 26th. St. Paul's Frogtown will be holding its Frogtown Festival complete with a Leap-O-Rama contest. Teams of two will attempt to leapfrog for one mile around West Minnehaha Park. Times for the fasted team will be sent to the Guinness book. The idea was originally to break the longest leapfrog contest but changed when organizers discovered that it had lasted eight days.

TURTLE RACING IS STILL "IN"

Yes, its true. Not only can Minnesota boast to have the Halloween Capital of the World but thanks to our distinguished House of Representatives, Longville Minnesota is official the Turtle Racing Capital of the World. In 1967, former tavern owner Ray Nyvall started.turtle races to raise money for the towns Little League team. These weekly races have continued today and actually draw hundreds of onlookers. The town has even doubled its population on race days to about 400!!! At 2:00 every Wednesday, Main St. is closed down and a 15 foot wide circle painted on the pavement is surrounded by determined racers and onlookers. The first place contestant wins a t-shirt and the Turtle Medallion which he or she has to return after a few minutes so it can be given to next week's winner. Participants bring their own turtles or actually rent one from locals who catch them for $1 to $2.

ARTICLES OF INTEREST

Among the different Reptile magazines and books there are also a few other magazines that offer some wonderful articles on Herps. Recently, International Wildlife magazine (Sept-Oct 1992) had a wonderful pictorial on chameleons. The photos by Art Wolfe were incredible and included chameleons, Parson's and Yemenese chameleons. In the past this magazine has had article on a variety of rain forest herps including eyelash vipers. Check your local library for back issues.

MHS members Dan Keyler and Barney Oldfield had a wonderful article on timber rattlesnakes in the May-June issue of THE MINNESOTA VOLUNTEER magazine called VELVET TAILS IN THE BLUFFLANDS. Along with some stunning photos and the article on their research were charts on their range and anatomy. They also gave some tips on safety while hiking and snake bite information including the Minnesota Regional Poison Center hotline number (612-221-2113 or outside the metro area, call 800-222-1222). Dan and Barney will be giving a lecture on their research at the Raptor Center on the U of MN St. Paul Campus on October 11th. The VOLUNTEER is produced by the Minnesota DNR.
