Abstract
Abstract
Populations are constantly perturbed, both in time and in space. In this talk, I will consider communities living in patchy environments coupled by dispersal, where each patch experiences its own environmental fluctuations, a setting often referred to as a fitness seascape. I will show that the combination of temporal fluctuations and dispersal changes the conditions for coexistence, and allows diverse communities to persist even when species compete for a single limiting factor. This behavior stems from a basic property of geometric Brownian motion, where the typical growth of a population differs from its average growth.
