Document Summary

Competition and the niche case studies included. Communities: a group of interacting species that co-occur in a particular place. The physical environment affects community composition: direct abiotic. Determined by environmental tolerances of the species. Mediated by interactions with other species that are subject to filtering. Evening primrose has local ecotypes that depend on abiotic conditions: its herbivore community changes depending on ecotype, an indirect filtering effect mediated by the host plant, effects of filtering on one species can ripple through the community. Neutral and niche based models of community assembly. Succession what is it, how to study it. Sere = the series of stages that follow one another in succession. Pioneer community = the first community, in a successional sequence of communities, to be established following a disturbance. Climax community = a community that occurs late in succession whose populations remain stable until disrupted by disturbance.
