We are the ‘Predator-Prey Interactions’ research group, led by Johanna Mappes, at the University of Jyväskylä, Finland. Our research examines how the interactions between predators and prey alter the co-evolutionary dynamics between antagonists. Most of our research is done using the wood tiger moth, Arctia plantaginis, as a study system. We investigate different aspects of its behaviour, genetics, and anti-predator defences in order to understand the processes enabling signal polymorphism (within-population signal variation), as well as divergence between populations. Currently we are focused on studying the causes and consequences of variation in chemical defences in aposematic insects, how predator and prey communities can influence selection on signaling prey, and how prey can defend themselves against multiple types of predators. We occasionally address some of these questions in vipers and poison frogs too.
