The evolution of mutualism between host and symbiont communities plays an essential role in maintaining ecosystem function and should therefore have a profound effect on their range expansion dynamics. In particular, the presence of mutualistic symbionts at the leading edge of a host-symbiont community should enhance its propagation in space. I will present a theoretical framework that captures the eco-evolutionary dynamics of host-symbiont communities, and allow us to investigate how the evolution of resource exchange may shape community structure during range expansion.
