THE INFLUENCE OF HYDRODYNAMICS ON SENSORY INFORMATION AND ORIENTATION BEHAVIOR IN THE CRAYFISH, ORCONECTUS RUSTICUS
 
Many aquatic organisms extract important ecological information from the fine-scale distribution of chemical signals in flowing habitats. This information is used in a number of different behaviors including larval settlement, predator avoidance, mate selection, and foraging behaviors. Information in chemical signals is structured by the hydrodynamics associated with a particular environment. Thus, hydrodynamically-different environments will have different chemosensory information. I will present a series of experiments that investigates how the hydrodynamics of flow associated with different stream habitats determines the chemosensory information available in that habitat. These experiments, coupled with subsequent behavioral trials using the crayfish, Orconectes rusticus, have shown that chemically-mediated behaviors may be altered or constrained in different habitats as a result of changes in the hydrodynamics. These results can be used to further our insight into the interplay between physics of flow, sensory biology, and ecologically-relevant behaviors.
