This book discusses the intimate physiology of the endocrine system and the pivotal role of hormones in coordinating basic body processesThe completely revised third edition of this popular text provides a description of hormones in animals and considers their evolution and roles in coordinating bodily functions such as nutrition, reproduction, and the control of calcium, water and salt levels in the body. Information about the hormones is thoroughly integrated with knowledge of the animals' basic physiology and manner of life. The book emphasizes the differences in hormone function between different species living in contrasting natural environments.The completely revised third edition of this popular text provides a description of hormones in animals and considers their evolution and roles in coordinating bodily functions such as nutrition, reproduction, and the control of calcium, water and salt levels in the body. Information about the hormones is thoroughly integrated with knowledge of the animals' basic physiology and manner of life. The book emphasizes the differences in hormone function between different species living in contrasting natural environments.The long-awaited third edition of this popular textbook, which has been unavailable for several years, is completely revised and updated. It retains the successful format of previous editions, dealing with the nature, actions and roles of hormones among vertebrate animals. Special emphasis is placed on the evolution and origins of hormones and their receptors; the role of hormones in the physiological coordination of vertebrates; and each endocrine process in the context of the organism's physiology, ecology, and evolution. Comparative Vertebrate Endocrinology discusses the intimate physiology of the endocrine system and the pivotal role of hormones in coordinating basic body processes such as nutrition, reproduction, calcium metabolism, and osmoregulation, as well as their contributions to animal coloratiolÓh
