How does chronic exposure to pharmaceuticals impact crayfish behavior and physiology

Project Overview
Project Abstract: 
A significant and increasing contributor to pollution is pharmaceutical compounds. These compounds typically serve to modify the physiology or behavior, of the intended target system, without killing the organism. The wide range of entry points into freshwater systems reaffirms that animals living within those habitats face continuous exposure to pharmaceuticals, even if only at low doses. Crayfish will be exposed to a common over the counter medication (aspirin) in environmentally relevant doses ( 0.5, 1.5 ug/L) for a 7 day period in flow through experimental streams. They will undergo a behavioral assay every day and at the end of the 7 day period, be sacrificed in order to extract tissue samples. Mass spectrometry will be performed on all tissue samples in order to assess physiological impacts.
