Symposium 14: Ant communities and biodiversity: community ecology
A central goal of ecology is to understand how interactions among species shape the structure of communities. Due to their abundance in terrestrial habitats, ants have been among the most important subjects for studies of species coexistence, biodiversity, and community organization. This symposium will present recent work from around the world on how biotic interactions and abiotic factors shape the organization of communities in natural and agricultural ecosystems. Particular topics will include the effects of competition on species assemblages, community development, ant-plant interactions, and the causes of numerical dominance.
