Enhanced Trophic Transfer of Chlorpyrifos from Resistant Hyalella azteca to Inland Silversides (Menidia beryllina) and Effects on Acetylcholinesterase Activity and Swimming Performance at Varying Temperatures
This excel workbook contains data from a study of trophic transfer of radiolabeled (C-14) chlorpyrifos from organophosphate-resistant Hyalella azteca to a known predator, the Inland silverside Menidia beryllina. Fish were fed 15 dosed (~ 1 ng/animal) or control H. azteca for 7 days at two temperatures, 18 and 23°C, to simulate changes anticipated under global climate change (GCC). Following feeding, fish were analyzed for critical swimming speed (Ucrit) and brain acetylcholinesterase (AChE) activity. Total chlorpyrifos concentrations, as well as percent parent compound as a a measure of biotransformation, were measured in both H. azteca and M. beryllina.
