The Ecological Society of America The Ecological Society of
America (ESA) is a nonpartisan, nonprofit organization of
scientists founded in 1915 to: - promote ecological science by
improving communication among ecologists; - raise the public’s
level of awareness of the importance of ecological science; -
increase the resources available for the conduct of ecological
science; and - ensure the appropriate use of ecological science
in environmental decision making by enhancing communication
between the ecological community and policy-makers. Ecology is
the scientific discipline that is concerned with the
relationships between organisms and their past, present, and
future environments. These relationships 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.
ESA’s over 10,000 members conduct research, teach, and use
ecological science to address environmental issu
