For upper-level undergraduate courses in herpetology, found in departments of Biology, Zoology, Natural Resources, Wildlife, and Conservation Biology. Collaboration by the six authors-whose research specializations include autecology, synecology, systematics, evolution, morphology, physiology, and behavior-emphasizes the integration of information from different biological specialties to produce a comprehensive picture of amphibians and their important roles in modern ecosystems. This book presents the biology of amphibians and reptiles as the product of phylogenetic history and environmental influences acting in both ecological and evolutionary time.
