Research into the lives of animals in their natural environments has revealed a rich tapestry of complex social relationships and previously unsuspected social and mating systems. The evolution of this behavior is increasingly well understood. At the same time, laboratory scientists have made significant discoveries about how steroid and peptide hormones act on the nervous system to shape behavior. An exciting and rapidly progressing hybrid zone has developed in which these two fields are integrated, providing a fuller understanding of social behavior and the adaptive functions of hormones.
This book is a guide to these fascinating connections between animal social behavior and steroid and peptide hormones--a synthesis designed to make it easier for graduate students and researchers to appreciate the excitement, engage in such integrative thinking, and understand the primary literature. Throughout, Elizabeth Adkins-Regan emphasizes concepts and principles, hypothesis testing, and critical thinking. She raises unanswered questions, providing an unparalleled source of ideas for future research. The chapter sequence is by levels of biological organization, beginning with the behavior and hormones of individuals, proceeding to social relationships and systems, and from there to development, behavioral evolution over relatively short time scales, life histories and their evolution, and finally evolution over longer time scales. The book features studies of a wide variety of wild and domestic vertebrates along with some of the most important invertebrate discoveries.
"Elizabeth Adkins-Regan takes the reader sledding from brain behavior and from hormones to gene expression, up and down through levels of analysis that often change within a single sentence."--Ellen D. Ketterson, Science "Hormones and Animal Social Behavior masterfully achieves Adkins-Regan's goal of integrating behavioral endocrinology with ecological and evolutionary studies... I predict that this outstanding book will soon become a classic in behavioral biology."--Randy J. Nelson, BioScience "Adkins-Regan's book is a timely and very welcome contribution that will be hoped to set the standards for the study of the neuroendocrinological basis of behavior in the wild."--Aldo Poiani, Austral Ecology
