This graduate-level course investigates how community properties -- species richness, and abundance distribution -- are influenced by evolutionary history, by landscape phenomena such as dispersal and migration, and by local factors such as the physical environment, disturbance, competition, predation, and mutualism. Mechanistic models of community dynamics, including succession, are discussed. The influence of species diversity on ecosystem function is discussed, and all aspects of the course are related to conservation science. Odd years only.
