More than 20 years after the ban of DDT and other organochlorine pesticides, pesticides continue to be detected in air, rain, soil, surface water, bed sediment, and aquatic and terrestrial biota throughout the world. Recent research suggests that low levels of some of these pesticides may have the potential to affect the development, reproduction,

This substantially updated edition presents fundamental principles and concepts behind the various types of toxicological studies, and explains how to design and conduct studies and interpret results. The text explains the increasing need to monitor, assess, and reevaluate the toxicity database of many agents and evaluates the place of individual studies in the overall toxicological assessment of a chemical. Concise descriptions of the formats of in vivo and in vitro studies and methods used in assessing endpoints of toxicity make this an essential introduction and guide for anyone who needs to understand or conduct toxicological studies. Reflecting increasing interest in the "Three Rs" (Reducing, Refining, and Replacement of existing animal tests) in recent years, the Second Edition includes much more information on a variety of new alternative testing protocols. Particular attention is given to the new in vitro alternative testing procedures being incorporated into EEC regulations. The text also covers studies required by regulatory agencies around the world.

Hormones and Reproduction of Vertebrates, Volume 3: Reptiles is the third of five second-edition volumes representing a comprehensive and integrated overview of hormones and reproduction in fishes, amphibians, reptiles, birds, and mammals. The book includes coverage of endocrinology, neuroendocrinology, physiology, behavior, and anatomy of reptilian reproduction. It provides a broad treatment of the roles of pituitary, thyroid, adrenal, and gonadal hormones in all aspects of reproduction, as well as descriptions of major life history events. New to this edition is a concluding assessment of the effect of environmental influences on reptiles. Initial chapters in this book broadly examine sex determination, reproductive neuroendocrinology, stress, and hormonal regulation as it relates to testicular and ovarian function. Subsequent chapters examine hormones and reproduction of specific taxa, including turtles, crocodilians, lizards, and snakes. The book concludes with an examination of endocrine disruption of reproduction in reptiles. Hormones and Reproduction of Vertebrates, Volume 3: Reptiles is designed to provide a readable, coordinated description of reproductive basics in reptiles, as well as an introduction to the latest trends in reproductive research and a presentation of our understanding of reproductive events gained over the past decade. It may serve as a stand-alone reference for researchers and practitioners in the field of herpetology or as one of five coordinated references aligned to provide topical treatment across vertebrate taxa for researchers, practitioners, and students focused on vertebrate endocrinology. - Covers endocrinology, neuroendocrinology, physiology, behavior, and anatomy of reptile reproduction - Includes pituitary, thyroid, adrenal, and gonadal hormones - Focuses on turtles, crocodilians, lizards, and snakes - Provides new coverage on environmental influences on reptiles
