| Abstract | Grass shrimp, Palaemonetes pugio, when exposed to sublethal concentrations of methyl or ethyl parathion, become more susceptible to predation by gulf killifish, Fundulus grandis. An increase in spontaneous activity renders them more easily detected by a predator, and they fatigue more quickly when being pursued. Such changes in a multi-prey community could result in altered predator preferences and subsequently could change community structure and trophic relationships.
