Evolutionary Ecology of Social and Sexual Systems

Crustaceans are used as model systems for studying behavioral and physiological processes common to many animals. Crustaceans are especially attractive to neuroethologists since most of their behavioral repertoire is controlled by a nervous system of relatively low complexity readily accessible for a variety of experimental techniques. Many basic neural mechanisms were first discovered in crustacean preparations and have then been generalized to many other organisms. In several taxa of social crustaceans, communication signals of different modalities are exchanged between conspecifics. Incoming signals are received, relayed, and sometimes integrated by the peripheral nervous system. The underlying mechanisms have been intensively studied and are reasonably well understood. Presently, the experimental transition from research on the peripheral nervous system to the central brain areas of higher order processing has begun. This will significantly improve our understanding of how signals are integrated into adaptive behavioral responses, thus illustrating how nervous systems shape communication.
