Spatial resource heterogeneity stabilizes local and regional predator-prey dynamics in ecologically realistic networks.

ABSTRACT: Spatial resource heterogeneity (SRH; the variable spatial distribution of resources) is a surprisingly understudied component of oscillatory predator-prey dynamics. SRH may be particularly important in large, ecologically realistic networks where different patterns of resource distribution can manifest, which have important implications for spatial synchrony. Here, we explore how SRH in large spatial networks influences both local and regional predator-prey stability. To do so, we employ a spatially explicit Rosenzweig-MacArthur model and vary resource distribution accordingly: homogeneously distributed resources of low, medium, and high productivity and heterogeneously distributed resources. The latter includes networks with SRH of random variability in productivity ("random networks") or
