Book Description
Comparative endocrinology is one of the most rapidly developing subdis ciplines within the field of endocrinology, and it is having a significant impact on research at the molecular, cellular, organisma1 and environmental levels. Much of the current ferment in endocrinology is in reproductive endocrinology. The purpose of this volume on hormones and reproduction in fishes, amphibians and reptiles is to summarize our present understandings and to identify important research problems to be addressed in the area of comparative reproductive endocrinology. It was inspired by the gathering at Copper Mountain, Colorado, of eminent endocrine scientists from around the world on the occasion of the Tenth International Symposium on Comparative Endocrinology in July, 1985. While preparing for that meeting, we decided that a special volume on reproductive endocrinology was needed to summarize what is known and to stimulate research in particular directions. Why do we emphasize fishes, amphibians and reptiles? First, knowledge about the reproductive endocrinology of these ectothermic vertebrates can provide a clearer picture of the evolution of reproductive hormones and their effects on target organs. This comparative approach can lead to new theories about the evolution of reproductive control mechanisms. Second, studies concerning the reproductive endocrinology of "lower" vertebrates can result in development of "model systems" for application to studies of birds and mammals. Indeed, information about the patterns of reproductive control in ectothermic vertebrates can tell us which are evolutionarily stable and which are labile.

Book Description
The second edition of the Field Guide to Amphibians and Reptiles of Illinois offers up-to-date information on the state’s 102 species of frogs and toads, salamanders, turtles, lizards, and snakes. Detailed descriptions by the authors include habitats, distinguishing features, behaviors, and other facts, while revised range maps and full-color photographs help users recognize animals in the field. In addition, an identification key and easy-to-navigate page layouts guide readers through extensive background material on each species' population, diet, predators, reproduction, and conservation status. A one-of-a-kind resource, the Field Guide to Amphibians and Reptiles of Illinois is a definitive guide aimed at biologists, teachers, students, wildlife specialists, natural resource managers, conservationists, law enforcement officials, landowners, hobbyists, and everyone else eager to explore herpetology and nature in the Prairie State.

Book Description
Physiology of the Amphibia, Volume II focuses on the various aspects of amphibian reproduction, both physiological and behavioral, and the interrelationship between these mechanisms and the environment. Organized into five chapters, the book begins with the integrative functions of the amphibian brain. It then describes the cytophysiology of the amphibian adenohypophysis, as well as their reproductive organs and associated sexual structures. It also discusses the physiology of the process of yolk formation, vitellogenesis. The reproductive and courtship patterns and intersexuality among amphibians are also described. This book will be useful to general biologists as a reference source and to students with interests in animal physiology.

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
