This book, first published in 1987 and here reprinted with a new foreword by the authors has become a classic in the field of herpetology. In ecological and evolutionary research snakes occupy a unique niche. Studies of their adaptations and life histories have broad applications for the most basic questions in biology. This book fills the need for an up-to-date text/reference in the growing field of snake ecology and evolutionary biology. Here, in one volume is an extensive review of the biology of these fascinating reptiles, including topics such as zoogeography, fossil history, systematics, foraging and reproduction. With contributions from many leading herpetologists, the work is divided into sections on Systematics and Morphology, Methods and Techniques and Life History and Ecology. Each section summarizes what is known about these major fields of snake biology. This book serves the needs of those actively involved in research as well as the amateur naturalist and the beginning student. Dr. Richard A. Seigel became interested in herpetology while an undergraduate at Rutgers University, where he received his B.A. in Zoology and Physiology in 1977. He continued his work with amphibians and reptiles while getting his M.S. in Biological Sciences from the University of Central Florida in 1979 and his Ph.D. from the University of Kansas in 1984. He is currently Full Professor and Chair of the Department of Biological Sciences at Towson University in Maryland. Dr. Siegel's primary research interests are in the population ecology and conservation biology of amphibians and reptiles. He has published over 50 peer-reviewed papers and has co-authored or edited four texts on the ecology and biology of snakes. From 1993-2000, he was the Editor-in-Chief of the Journal of Herpetology, the largest international publication in its field. Joseph T. Collins has written more than 200 articles on reptiles, amphibians, and fishes throughout North America and twenty-three books, inl“7
