Book Description
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.

Book Description
One of the most important hotspots of herpetological biodiversity in the United States, California is home to many endemic amphibians and reptiles found nowhere else on earth. Many of these taxa have unique ecological and morphological specializations, and their management is an important conservation challenge. Increasing climate change impacts, human development, and extreme drought mean many of these species face an ever-greater risk of extinction. California Amphibian and Reptile Species of Special Concern provides an up-to-date synthesis of the current state of knowledge regarding the biology and conservation risks faced by 45 of California’s most sensitive amphibian and reptile species. With the goal of enhancing management based on the best available science, the authors developed a novel set of risk metrics to identify special concern species and the threats they face, including population declines, range size and restrictions, and ecological specializations and niche restrictions. In addition to detailed species accounts, this book provides a quantitative analysis of the conservation status and pressing management issues facing individual species and the state’s amphibian and reptile fauna as a whole. The volume focuses on identifying threats, concrete recommendations for management and recovery, and future research needs. The text is complemented by detailed distribution maps, color photos, and graphs. Written in nontechnical language, California Amphibian and Reptile Species of Special Concern will be a valuable resource to a broad range of users from resource managers, field biologists, and academic herpetologists to students and recreational naturalists. Published in association with the California Department of Fish and Wildlife.

Book Description
Although reptiles and amphibians are different classes of vertebrates, they have long been studied together in the field of herpetology. This guide provides an account of the herpetology of Montana, first providing descriptions of herpetofauna biology, habitats in Montana, field observation, and conservation and management, then moving onto species accounts of 36 salamanders, frogs, toads, turtles, lizards, and snakes occurring in the western state. Including numerous color photographs, the species accounts provide information on morphology, taxonomy and distribution, habitat and behavior, and reproduction and development. Also provided are a simplified key to aid identification, a glossary, and appendices detailing reproductive features and other information.

Book Description
This is the first guide yet produced to the amphibians and reptiles of New York State, a large and heavily populated state that hosts a surprisingly diverse and interesting community of amphibians and reptiles. This much needed guide to the identification, distribution, natural history and conservation of the amphibians and reptiles of New York State fill a long-empty niche. The book is the first comprehensive presentation of the distributional data gathered for the New York State Amphibian and Reptile Atlas project. With more than 60,000 records compiled from 1990-1999, this extraordinary and up-to-date database provides a rich foundation for the book. This volume provides detailed narratives on the 69 species native to New York State. With a heavy emphasis on conservation biology, the book also includes chapters on threats, legal protections, habitat conservation guidelines, and conservation case studies. Also included are 67 distribution maps and 62 pages of color photographs contributed by more than 30 photographers. As a field guide or a desk reference, The Amphibians and Reptiles of New York State is indispensable for anyone interested in the vertebrate animals of the Northeast, as well as students, field researchers and natural resource professionals.

Book Description
This new title covers the curious world of reptiles and amphibians, both common and rare, found in the Indian faunal limits. There has been no book to rival J C Daniel's earlier Book of Indian Reptiles, also published by the Bombay Natural History Society in 1983. He has now presented an entirely new text of not only a large number of reptiles, but has also described frogs, toads, and other amphibians, a much neglected group that is revealed in this book as picturesque, and biologically interesting as any other group of animals. This book contains field observations and photographs, and descriptions of 175 species including 53 snakes, 45 lizards of various groups, 31 tortoises and turtles, and 45 amphibians. Almost each species has been illustrated with the line drawings, photographs and reproductions of paintings from the Journal of the BNHS. The book satisfies professional zoologists, amateur naturalists, students and the interested general reader alike. There is a reference section with reptiles and amphibians listed separately. Photographic contributions from several members of the BNHS, add contemporary appeal to this exciting new field guide, which also contains snippets of historical information.

Book Description
Tips for finding these species, conservation issues, exotic species, and other topics are covered in additional chapters." "Of particular note is the enclosed compact disc, narrated and produced by well-known naturalist Lang Elliott, that will make it easy to learn to identify all the frogs and toads by their songs. The CD also includes a long unnarrated series of frog choruses."--BOOK JACKET.
