George A. Feldhamer is an Associate Professor of Zoology, and Coordinator of the Environmental Studies Program, at Southern Illinois University at Carbondale. His research has focused on mammalian populations, ecology, and management, introduced cervid biology, and threatened and endangered species. He is a former Associate Editor of the Wildlife Society Bulletin, and coeditor of Wild Mammals of North America; Biology, Management, and Economics. Dr. Feldhamer has 20 years of experience teaching an upper division mammalogy course.

Lee Drickamer received a PhD in zoology from Michigan State University and is currently teaching at Northern Arizona University. His research interests include population biology, behavioral ecology of rodents, reproductive traits in field mice, comparative mating behavior of stink bugs, and dominance in domestic swine. Lee has been very active in the Animal Behavior Society and the American Society of Zoologists. He also is a member of the American Society of Mammalogists, American Society of Primatologists, British Ecological Society, Ecological Society of America, Illinois Academy of Science, International Society for Behavioral Ecology, Society of American Naturalists, and Wilson Ornithological Society. Lee is lead author of Drickamer et al: Animal Behavior, 4e, also published by WCB/McGraw-Hill.

Stephen H. Vessey is Professor Emeritus of Biological Sciences at Bowling Green State University. His research interests include the behavioral ecology of mammals, especially primates and rodents. He has been studying a population of white-footed mice in northwestern Ohio for more than 25 years. He is a formed associate editor of the Journal of Mammalogy and is a Fellow of the Animal Behavior Society. He has taught mammalogy and animal behavior at Bowling Green for 28 years, and is co-author of Animal Behavior, 4/e with Lee Drickamer.

Balancing breadth and depth of coverage, this text is tailored to a one-semester mammalogy course appropriate for upper level undergraduates and graduate students with a basic background in vertebrate biology.
