Product Description

Book Description

This comprehensive key for identifying specimens of amphibians and reptiles in the U.S. and Canada--the first since 1983--incorporates the wealth of scientific findings generated by molecular systematics (the study of DNA to determine genetic relationships) and simplifies identification by making geographic origin a leading factor. A dichotomous key (that is, one that gives the user only two choices at each level of morphological scrutiny), it is designed for use in college-level herpetology or vertebrate biology courses. It will be especially useful as an effective tool for teaching the principles of taxonomy and for introducing students to the systematics of amphibians and reptiles. While it can serve to identify specimens in the field, it is intended primarily as a teaching tool for classifying preserved specimens whose geographic origins are known.

The dichotomous keys are supplemented by 257 line illustrations depicting the distinguishing morphological characteristics of salamanders, frogs and toads, turtles, alligators and crocodilians, amphisbaenians (wormlike lizards), lizards, and snakes. The drawings, along with frequent references to the species descriptions, maps, and photographs in the Peterson Field Guide Series, make the key user friendly and increase its appeal to undergraduate and amateur herpetologists.

This review is from: A key to amphibians & reptiles of the continental United States and Canada (Paperback)
This key is a must for anyone that is seriously interested in reptiles or amphibians. For instructors of Herpetology lab this book will prove to be invaluable, the illustrations and current phylogenetic classifications will aid in teaching.

5.0 out of 5 stars This is a great overview of herps!!, Mar 12 2007
By Andrea Franklin - Published on Amazon.com
This review is from: A key to amphibians & reptiles of the continental United States and Canada (Paperback)
This book provides an extensive key to amphibians and reptiles in North America. If you are studying herpetology, this book has many diagrams in it that really help with keying out dinstinguishing characteristics. Plus, the book is set up simply in plain English. Other keys that I have used were not as extensive as this one, and they were usually confusing. This key takes away all the ambiguity.

This review is from: A key to amphibians & reptiles of the continental United States and Canada (Paperback)
Some of the taxonomy in this book is a little questionable but it gets the job done. I do not reccomend it for live IDs but only vouchared specimans.
