Communities in Patchy Environments: A Model of Disturbance, Competition, and Heterogeneity

  • Chapter

Part of the Ecological Studies book series (ECOLSTUD,volume 86)

Abstract

All landscapes are to some extent patchy. The biological heterogeneity of communities on patchy landscapes reflects the time scales of local biotic interactions and abiotic disturbance, the time and space scales of dispersal, and (especially) the interaction of these scales. To investigate these factors, we examine here a simple model that provides a framework for building models of patchy communities directly from hypotheses about time scales. The model has numerous applications (Caswell and Cohen, 1991, in preparation); here we focus on the interplay of competition and disturbance as well as the kinds of biological heterogeneity that can be maintained by that interplay.
