Johanna Mappes explores interspecies interactions, particularly the evolution of warning signals and mimicry among prey with chemical defences but also the evolution of sexual and asexual reproduction, and bacterial virulence. From the simplest cells to the complex societies of bees or humans, life thrives on communication. Often, the fate of organisms hinges upon communicating with other species. Organisms communicate with predators, parasites and herbivores, for instance, through colour and chemical defences, and with their fellow organisms through pheromones. Although theory and data show how signals arise in simple interactions between few species, we have little theory and little data on how signalling between species affects the population dynamics of their communities.
Mappes is an esteemed evolutionary ecologist who works at the Department of Biological and Environmental Science of the University of Jyväskylä. The American Academy of Arts and Sciences, one of the oldest learned societies in the world, invited Mappes as a Foreign Honorary Member on 18 April 2018. Mappes also served as Academy Professor in 2009–2013. She headed the Centre of Excellence in Biological Interactions Research in 2012–2017.
