"The book reveals a richly illustrated panoramic view of animal behavior and, where it can, it also provides examples of the physiological, neurobiological and molecular genetic mechanisms that may underlie it. . . . Dugatkin's text . . . can be enjoyed by anyone who has an interest in the beauty of animal behavior. . . . Excellent."--Times Higher Education, on the second edition "Up to date, highly integrative, and richly illustrated. It thus merits serious consideration by anyone looking for a textbook to support undergraduate offerings in animal behavior or behavioral ecology. . . . Principles of Animal Behavior is comprehensive and readable, summarizing not only what is well documented but more importantly where integrated understanding is lacking, and thus where further research will prove most profitable."--Animal Behavior, on the first edition
