Book Description
This profusely illustrated comprehensive key for identifying amphibians and reptiles from the continental United States and Canada incorporates a wealth of scientific findings. Since the first edition was published in 1998 and the second in 2012, the number of currently recognized species of native amphibians and reptiles in the area covered by this key has increased from 545 to 634 to 685, and the number of established non-native species has increased from 39 to 58 to 67. The increase in native taxa reflects the dynamic nature of modern systematics and the use of new (especially molecular) techniques to elucidate relationships and redefine species boundaries. The increase in non-native species reflects the porosity of the North American borders when it comes to controlling animal imports. The key is easy to use and illustrated with outstanding line drawings that show details of color patterns and structures used for identification. To accommodate the additional taxa, the number of line drawings in this third edition has increased from 257 to 279 to 295. In addition, nine maps illustrate the distributions of species that have been recognized since the publication of maps in the most recent editions of the Peterson Field Guides to the reptiles and amphibians of eastern, central, and western North America. A large number of annotations detail current taxonomic ambiguities or disagreements and the literature cited has been expanded. Collectively these features enhance opportunities to teach and learn the classification and identification of amphibians and reptiles in the continental United States and Canada.

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
"The premiere reference book on the 108 species of frogs inhabiting North America north of Mexico. An unparalleled synthesis of the biology and behavior of all native and nonindigenous species, this two-volume, extensively referenced resource has been called the most important book ever published on North American anura. Color photographs and range maps accompany species accounts detailing information on etymology, nomenclature, identification, distribution, fossil record, systematics and geographic variation, life history and ecology, behavior, population and community biology, and conservation. This new edition of the text contains the following updates: Literature citations have been added from 2012 to 2021, now spanning from 1709 to 2021. Distribution maps have been updated, recording the decreased ranges due to declining amphibian populations. Photographs have been revised to ensure the highest digital quality. Anaxyrus williamsi and Lithobates kauffeldi, newly described species, have been included. An account is also included for Gastrophryne mazatlanensis, now recognized as occurring within the United States. Generic keys have been added. A brief section on N.A. frogs in history and art have been added. Nomenclature has been updated (Incilius for Ollotis). Now the only up-to-date and comprehensive resource for those trying to protect amphibians in the US and Canada, as well as for researchers and wildlife managers who study biodiversity"--

Book Description
From one of the most trusted names in field guides comes a new and lavishly illustrated guide to identifying North America's most common birds, mammals, insects, reptiles, and amphibians, plus fish and other aquatic creatures. Broad in scope and clearly organized, National Geographic Illustrated Guide to Wildlife is just like having five field guides in one. Each of the five realms of wildlife gets a chapter, and each chapter identifies 160 of the most common and most interesting animals around, providing essential information and a bullet list of key points on each species. Photographs and original artwork represent 900 species total, making this the ultimate field guide to the creatures of the continental United States and Canada, from your own backyard into the deepest wilderness.

Book Description
Current Therapy in Reptile Medicine and Surgery is a valuable reference that emphasizes topics of real clinical relevance in reptile and amphibian medicine. With details on therapeutic regimens, this text also features coverage of infectious diseases, anesthesia, surgery, and advances in biology and conservation. Colorful illustrations showcase exotic animals, and numerous tables and figures provide quick access to essential information. "This is a great book for anyone interested in herptile medicine and surgery, worth every penny and I am sure will go on to become a regular series." Reviewed by: Jonathan Cracknell. Date: 25/07/2014 - Selected topics of real clinical significance from the latest veterinary scientific literature explore today's reptile and amphibian practice. - A discussion of the most current theory and practical applications of diagnostic endoscopy in reptiles provides insight into minimally-invasive endoscopic procedures, including biopsy techniques. - Expert contributors combine forces to bring you the most cutting-edge information available, offering authoritative and sometimes controversial opinions in particular areas. - Expert contributors offer the most current thoughts on diagnosing new and emerging diseases, including a thorough review of molecular diagnostics. - The latest therapeutics are discussed, and the most up-to-date formulary and library of normal clinical pathology values is provided. - The most current and comprehensive discussion of amphibian medicine in print in the last decade!

Book Description
IN THIS REVISED edition of Amphibians and Reptiles of Texas, James R. Dixon adds to and updates the extensive information given in the first edition. A new section on conservation issues highlights some of the problems facing the continued survival of amphibians and reptiles, particularly commercial collecting and habitat destruction. Taxonomic changes have been made to reflect the latest scientific information, and the extensive listing of the literature on Texas amphibians and reptiles has been updated through April, 1999. Going back to the writings of French botanist Jean Louis Berlandier, who encountered Texas herpetofauna during his travels from 1828 to 1834, this list covers more than 150 years of inquiry into the state's species and is also testimony to the distinguished careers of such herpetologists as Hobart M. Smith and, more recently, Chris McAllister. Another prominent feature of this book is the more than 150 distribution maps, which show by county the updated distribution records for all native Texas amphibians and reptiles, based on more than 13,000 county records and more than 110,000 individual localities. Professional and amateur herpetologists as well as environmentalists, wildlife specialists, campers, and hikers will find the dichotomous keys useful for identifying species at hand. This aid to identification is supported by a glossary, drawings and photographs, and complete scientific and common names.

Book Description
Herpetology has always been one of the most exciting disciplines of zoology. During the past few years the field has continued to grow, yet it has been plagued by scarcity of comprehensive, up-to-date textbooks containing the most important developments. This timely book fills that void. Through skillful synthesis, the author summarizes the diversity in the biology of living amphibians and reptiles and describes the breadth of current herpetological research. Topics covered include the evolution, classification, development, reproduction, population, and environmental issues surrounding the study of amphibians and reptiles. Designed as an advanced undergraduate textbook, Herpetology is a valuable resource for students, practitioners, and interested amateurs alike. - Provides an incisive survey and much needed update of the field - Emphasizes the biological diversity among amphibians and reptiles - Details the most recent research findings, citing ke
