Predation is one of the most dramatic processes in ecology and the benefits of avoiding it are some of the major drivers of evolution in prey species. However, appropriate responses to predation rely on the ability of prey to detect and correctly interpret information on their immediate level of risk. This information can mean drastically different things to different individuals – from “extreme danger” to “meal time!” – and can be destroyed or altered by environmental conditions. I will share some recent findings about how individuals respond differently to information on risk, how pollution has affected information use in freshwater systems, and how impacted Atlantic salmon may be adapting to predation in the presence of pollutants.
