Predator community structure affects how predators select for prey defences
Animals have evolved different defensive strategies to survive predation, among which protective coloration and chemical defences are particularly widespread and diverse. I will present results from the field and lab experiments in wood tiger moths and European adders investigating a hypothesis that such diversity has evolved as a response to multiple enemies. We found that heterogeneity in predator community composition can facilitate the evolution of polymorphic warning signals and a single species can have evolved producing separate chemical defences targeted to different predator types. These results highlight the importance of taking into account complex predator communities in studies on the evolution of prey defence diversity.
