AIMS THE EcoLOGIcAL SocIErY OF AMERIcA was founded in 1915 for the purpose of unifying the science of ecology, stimulating
research in all aspects of the discipline, encouraging communication among ecologists, and promoting the responsible application of ecological data and principles to the solution of environmental problems. Ecology is the scientific discipline that is concerned with the relationships between organisms and their past, present, and future environments. These rela- tionships include physiological responses of individuals, structure and dynamics of populations, interactions among species, organization of biological communities, and processing of energy and matter in ecosystems.
