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

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.
