Coexistence in a metapopulation model with explicit local dynamics
Many patch-based metapopulation models assume that the localpopulation within each patch is at its equilibrium and independent of changesin patch occupancy. We studied a metapopulation model that explicitly incorporates the local population dynamics of two competing species. The singularperturbation...

| Summary: | Many patch-based metapopulation models assume that the localpopulation within each patch is at its equilibrium and independent of changesin patch occupancy. We studied a metapopulation model that explicitly incorporates the local population dynamics of two competing species. The singularperturbation method is used to separate the fast dynamics of the local competition and the slow process of patch colonization and extinction. Our resultsshow that the coupled system leads to more complex outcomes than simplepatch models which do not include explicit local dynamics. We also discussimplications of the model for ecological systems in fragmented landscapes. |
