摘要: Ecological systems show a variety of characteristic patterns biodiversity in space and time. It is challenge for theory to find models that can reproduce explain the observed patterns. Since advent island biogeography these revolve around speciation, dispersal, extinction, but they usually neglect trophic structure. Here, we propose study spatially extended evolutionary food web model allows us large spatial with several layers. Our computer simulations gives rise simultaneously time, from species abundance distributions waxing waning geographic ranges. We position network plays crucial role when it comes time evolution range sizes, because context restricts occurrence survival especially on higher levels.
