Population and Community Ecology Program: This program supports fundamental studies in the broadly defined areas of population and community ecology. Topics include the population dynamics of individual species, demography, and fundamental ecological interactions affecting populations, communities, and their environments. Themes include, but are not limited to: population regulation; food-web structure and trophic dynamics; competition, predation, mutualism and parasitism; mechanisms of coexistence and the maintenance of species diversity; community assembly; paleoecology; landscape ecology; conservation and restoration biology; behavioral ecology; and macroecology. The Program particularly encourages studies that can be applied to a wide range of habitats and taxa across multiple spatial and temporal scales.
