Animal courtship is a process that results in two mature members of a species becoming a couple, usually with the intent to mate and produce offspring. Different species of bugs, birds, fish, reptiles, amphibians, and mammals have their unique sets of courtship rules and rituals. In Animal Courtship, learn the various ways species attract mates, including by singing, dancing, glowing, and even attacking.
Studies of animal behavior often assume that all members of a species exhibit the same behavior. Geographic Variation in Behavior shows that, on the contrary, there is substantional variation within species across a wide range of taxa. Including work from pioneers in the field, this volume provides a balanced overview of research on behavioral characteristics that vary geographically. The authors explore the mechanisms by which behavioral differences evolve and examine related methodological issues. Taken together, the work collected here demonstrates that genetically based geographic variation may be far more widespread than previously suspected. The book also shows how variation in behavior can illuminate both behavioral evolution and general evolutionary patterns. Unique among books on behavior in its emphasis on geographic variation, this volume is a valuable new resource for students and researchers in animal behavior and evolutionary biology.
