The concerted emergence of well-known spatial and temporal ecological patterns in an evolutionary food web model in space

Abstract Ecological systems show a variety of characteristic patterns of biodiversity in space and time. It is a challenge for theory to find models that can reproduce and explain the observed patterns. Since the advent of island biogeography these models revolve around speciation, dispersal, and ex...
