This first book-length exploration of behavioral mechanisms in evolutionary ecology illuminates long-standing questions about cause-and-effect relations between an animal's behavior and its environment. By focusing on biological mechanisms - the sum of an animal's cognitive, neural, developmental, and hormonal processes - leading researchers demonstrate how more integrated research can yield an enriched understanding of behavior. With studies of species ranging from insects to primates, the contributors examine the way various animals identify and use environmental resources and deal with ecological constraints, as well as the roles of learning, communication, and cognitive aspects of social interaction in behavioral evolution. Taken together, the chapters demonstrate how the study of internal mechanistic foundations of behavior in relation to their ecological and evolutionary contexts and outcomes provide new insights into such behaviors as predation, mating, and dispersal. Behavioral Mechanisms in Evolutionary Ecology shows how a mechanistic approach unites various levels of biological organization to provide a broader understanding of the biological bases of behavioral evolution.
