Habitat patchiness
WebAbstract. Mathematical models 1-3, field observations 4,5, and laboratory studies 6 all suggest that habitat patchiness (or 'fragmentation') profoundly affects species interactions. One especially widely cited idea is that patchiness stabilizes predator-prey dynamics 7,8.I performed the first test of this idea in a natural community by experimentally … WebMay 5, 2015 · Recent work has clarified how the effects of competition are influenced by body size (stage structure), order of arrival on the reef (priority effects), predator and prey behavior (in the case of competition for refuges), the spatial configuration of the reef habitat (patchiness), habitat quality (cryptic density dependence), and the spatial ...
