cover of A Systematic Study of The Lizards of The Deppei Group (Genus Cnemidophorus) in Mexico and Guatemala

A Systematic Study of The Lizards of The Deppei Group (Genus Cnemidophorus) in Mexico and Guatemala

By William E. Duellman and John Wellman

University of Michigan Press, 1960

Lizards of the genus Cnemidophorus long have been a thorn in the sides of herpetologists. Commonly known as whiptail lizards or racerunners, species in this genus occur in North, Central, and South America. Probably the most confusing thing about these lizards is the ontogenetic change in color pattern, which through its variety of manifestations runs the gamut in convergence and parallelism. The purpose of this study is to review the species of the deppei group of Cnemidophorus and to present a classification of them, using some taxonomic characters that previously have not been applied. During the course of this study, 2,302 specimens were examined, revealing the presence of three species and ten races. The species differ from one another in the relative size of the dorsal granules, the size of the body, color pattern, and ontogenetic change in color pattern. The ranges of the species appear to be discontinuous. The present distributions probably are the result of climatic shifts during the Pleistocene.

America's Snake

The Rise and Fall of the Timber Rattlesnake

Ted Levin

University of Chicago Press, 2016

There’s no sound quite like it, or as viscerally terrifying: the ominous rattle of the timber rattlesnake. It’s a chilling shorthand for imminent danger, and a reminder of the countless ways that nature can suddenly snuff us out.
 
Yet most of us have never seen a timber rattler. Though they’re found in thirty-one states, and near many major cities, in contemporary America timber rattlesnakes are creatures mostly of imagination and innate fear.
 
Ted Levin aims to change that with America’s Snake, a portrait of the timber rattlesnake, its place in America’s pantheon of creatures and in our own frontier history—and of the heroic efforts to protect it against habitat loss, climate change, and the human tendency to kill what we fear. Taking us from labs where the secrets of the snake’s evolutionary history are being unlocked to far-flung habitats whose locations are fiercely protected by biologists and dedicated amateur herpetologists alike, Levin paints a picture of a fascinating creature: peaceable, social, long-lived, and, despite our phobias, not inclined to bite. The timber rattler emerges here as emblematic of America and also, unfortunately, of the complicated, painful struggles involved in protecting and preserving the natural world.
 
A wonderful mix of natural history, travel writing, and exemplary journalism, America’s Snake is loaded with remarkable characters—none more so than the snake at its heart: frightening, perhaps; endangered, certainly; and unquestionably unforgettable.

cover of Amphibians and Reptiles of New England: Habitats and Natural History

Amphibians and Reptiles of New England

Habitats and Natural History

Richard M. DeGraaf

University of Massachusetts Press, 1983

Although numerous species of amphibians and reptiles live in New England and the northeastern Untied States, few people are aware of their existence of know much about their life histories, habitats, or distributions. This illustrated work provides such information, compiling the latest data on nearly sixty species. Included is a detailed account of each species' range, relative abundance, habitat, breeding period (from egg deposition through larval period), home range and movements, and food habitats. Additional comments and selected references are provided throughout. 

The book is designed specifically for use in New England. The regional approach makes it possible to examine the details of distribution and habitat preference, important factors because many of these species have local, disjunct populations. The authors stress that these species constitute a valuable resource requiring and deserving conservative measures and urge that reptiles and amphibians be considered in wildlife-management policy.

James H. Harding and David A. Mifsud

University of Michigan Press, 2017

The revised edition of this well-loved guide is the essential reference for the identification of amphibians and reptiles in the Great Lakes region. Fully updated treatments of over 70 species feature detailed information on the distribution, habitat, behavior, and life history of these fascinating animals. This edition includes all new distribution maps as well as 90 additional color photographs showing close-ups of distinguishing features, common color phases, and different metamorphic stages. A thorough introduction provides a wealth of information on the evolution, natural history, classification, and conservation of these animals and examines changing Great Lakes ecosystems and their impact on herpetological diversity. Amphibians and Reptiles of the Great Lakes Region is a must-have resource for teachers, students, naturalists, professional biologists, and anyone else with an interest in this region’s ecology.
