Communication in Complex Communities; Ecology Matters

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. For example, prey with defenses can evolve warning signals to prevent predators from attacking them. Although theory and data show how signals arise in simple interactions between a few species, there are large gaps in our understanding of how communication evolves in the rich communities we find in nature. Even more strikingly, we have little theory and little data on how signaling between species affects the population dynamics of their communities. I am going to dedicate my stay at the Wissenschaftskolleg to advancing our understanding of how communication evolves in communities that feature multiple trophic levels, differences in biodiversity, and how one species indirectly affects another.
