Richard W. Hill is Professor in the Department of Zoology at Michigan State University and a frequent Guest Investigator at Woods Hole Oceanographic Institution. He received his Ph.D. in Zoology from the University of Michigan. Apart from Sinauer Associates' editions of "Animal Physiology", Dr. Hill has authored two other books on the subject (the second with Gordon Wyse), as well as numerous articles for scientific journals, encyclopedias, and edited volumes. Among the awards he has received are the Outstanding Faculty Award (Michigan State University Senior Class Council) and election as Fellow of the American Association for the Advancement of Science. He was a U.S. Senior Fulbright Scholar in 2000-2001. His research interests include: temperature regulation and energetics in birds and mammals, especially neonates; and environmental physiology of marine tertiary sulfonium and quaternary ammonium compounds, especially in the contexts of biogeochemistry and animal-algal symbioses.

Gordon A. Wyse is Professor of Biology Emeritus and Lecturer at the University of Massachusetts, Amherst. He completed his Ph.D. at the University of Michigan, then did postdoctoral and sabbatical work at Stanford University and Harvard Medical School. Dr. Wyse helped found the graduate program in Neuroscience and Behavior at UMass Amherst. He has served on the Editorial Board of "Advances in Physiology Education" and as Associate Dean of Natural Sciences and Mathematics. His research interests include the neural control of feeding behavior and other behavior patterns.

Margaret Anderson is Professor of Biological Sciences at Smith College. After completing her Ph.D. at Stanford University, she undertook postdoctoral studies at the Universidad Cat#lica de Chile, Harvard University, and the University of Puerto Rico. At Smith, Dr. Anderson has served as an Academic Dean, Director of the Program in Neuroscience, and premedical advisor. She is one of six founding members of the Consortium of Medical Schools and Women's Colleges, and she contributes to several efforts that encourage women and minorities in the sciences. Her research interests include the functional properties of excitable cells.

Animal Physiology presents all the branches of modern animal physiology with a strong emphasis on integration among physiological disciplines, ecology, and evolutionary biology. The book takes an entirely fresh approach to each topic. Its full colour illustration program includes many novel, visually effective features to help students learn. Each of the 28 chapters starts with a brief animal example to engage student interest and demonstrate the value of the material that will be learned. The book includes five entire chapters that apply students' newfound physiological knowledge to curiosity provoking and important topics, including diving by marine mammals, the mechanisms of navigation, and training/disuse effects in muscle. The book is committed to a comparative approach throughout. While mammalian physiology is consistently treated in depth, emphasis is also given to the other vertebrate groups, arthropods, molluscs, and as appropriate additional invertebrates. Concepts and integrative themes are emphasized while giving students the specifics they need. The whole animal is the principal focus of this book. The pages are filled with information on everything from knockout mice and enzyme chemistry to traditional organ physiology, phylogenetic analysis, and applications to human affairs. Always, the central organizing principle for the array of topics presented is to understand whole animals in the environments where they live. Concepts from chemistry, physics, and mathematics are explained so the book will be accessible to science students at the sophomore or higher level. Neurophysiological principles are developed clearly and carefully, to help students understand important concepts in sufficient depth without being overwhelming. Pedagogical aids include embedded summaries throughout chapters, lists of key terms, study questions, partially annotated reference lists, an extensive glossary, and appendices on topics such as units of measure and logarithms. For all three authors, teaching physiology to undergraduate students has been a lifelong priority. The opening three chapters provide background material on physiological basics, cell molecular concepts, transport of solutes and water, ecology, and evolutionary biology. The remaining chapters are organized into five sections: Food, Energy, and Temperature Integrating Systems Muscle and Movement Oxygen, Carbon Dioxide, and Internal Transport Water, Salts, and Excretion
