The leading text in the field shows how researchers use scientific logic to study the underlying mechanisms and evolutionary bases of behavior, with emphasis on how evolutionary theory unifies the various sub-disciplines within animal behavior. It is a comparative and integrative overview of how and why animals as diverse as insects and humans behave the way that they do, linking behaviors to the brain, genes, and hormones, as well as to the surrounding ecological and social environments. The new edition, now in enhanced e-Book format, brings animal behavior and research to life like never before. The leading text in the field, Animal Behavior shows how researchers use scientific logic to study the underlying mechanisms and evolutionary bases of behavior, now with a streamlined presentation and Enhanced e-Book Dustin Rubenstein is Professor of Ecology at Columbia University and an integrative behavioral and evolutionary ecologist who studies (1) the evolution of complex animal societies and (2) how organisms adapt to and cope with environmental change.
