John H. Christy

I am an evolutionary biologist with primary interests in animal behavior. My research includes the natural history, behavior and ecology of crabs and other intertidal animals; sexual selection; animal communication, particularly courtship and including deception, coercion and harassment; the evolution of mate preferences; reproductive timing by intertidal animals, its patterns and consequences for the survival of eggs and larvae, and predation and predator avoidance behavior. I study the immediate social and ecological consequences of behavior and how they affect individual survival and reproductive success in the field. I believe that the adaptive function of a behavioral trait is best understood through combined study of its design, history, the current contexts in which it is expressed and selected, and the mechanisms that produce it.
