Research and collaboration

Aposematism is an antipredator strategy where a chemically defended (toxic, distasteful etc.) species advertises its unprofitability as prey to potential predators via warning signals such as bright colours. Here at the University of Jyväskylä we work on many different aspects of aposematism. Broadly speaking, we are interested in the initial evolution of aposematism and its maintenance, particularly the maintenance of diverse warning signals. We examine selection pressures acting on aposematic prey, optimal signalling, trade-offs in signal expression, geographic variation in warning signals, and the evolution of Batesian (harmless prey imitates aposematic) and Müllerian (aposematic imitates aposematic) mimicry. In addition to moths and snakes, we have long worked with wild bird predators and artificial prey in the novel world lab. For more information, visit us on https://predatorpreyinteractions.com/
