- Title
Spatially heterogeneous refugia and predation risk in intertidal salt marshes.
- Authors
Lewis, David B.; Eby, Lisa A.
- Abstract
In many ecosystems, including intertidal zones, habitat structure may vary spatially, profoundly affecting interactions between predators and prey. Spatial heterogeneity in habitat structure dictates a need to examine how interactions between predators and prey vary across the landscape. Landscape-level heterogeneity may generate distinct subpopulations of prey, with consequences for the stability of predator-prey systems. A single population existing on a homogeneous landscape may be driven extinct by environmental stochasticity or overly strong biotic coupling. The spatial distributions of real populations, however, are often patchy.
