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.

The valuation of ecosystem services can play an important role in conservation planning and ecosystemâbased management. Unfortunately, gathering primary, siteâspecific data is costly. As a result, a popular alternate method is to conduct a âbenefit transferâ (applying economic value estimates from one location to a similar site in another location). Among the potential pitfalls of such an approach, the correspondence (or lack thereof) between the locations is probably the most important for evaluating the probable validity of the benefit transfer.
Integrating conservation and development in the field: implementing ecosystem service projects
Ecosystem services can bridge biodiversity conservation and development needs, but there is little information available on how conservation organizations implement such projects. We documented 103 ecosystem service projects â from 37 countries â implemented by The Nature Conservancy (TNC) and the World Wildlife Fund (WWF).
Can tropical farmers reconcile subsistence needs with forest conservation?
If tropical farmers cannot be provided with sustainable landâuse systems, which address their subsistence needs and keep them gainfully employed, tropical forests will continue to disappear. We looked at the ability of economic landâuse diversification â with reforestation of tropical âwastelandsâ as a key activity â to halt deforestation at the farm level.
Creating multifunctional landscapes: how can the field of ecology inform the design of the landscape?
The opportunity exists to improve intensively managed landscapes (urban and agricultural areas dominated by human activities) through greater engagement of ecologists in the process of ecological landscape design. This approach encourages exploration of multifunctional solutions to meet the needs of growing populations in many areas around the world, while minimizing the negative impacts of human activities on the environment. This is achieved by incorporating theoretical and applied principles from the fields of landscape ecology, agroecology, and ecological design.
Maximizing water yield with indigenous nonâforest vegetation: a New Zealand perspective
Provision of clean freshwater is an essential ecosystem service that is under increasing pressure worldwide from a variety of conflicting demands. Water yields differ in relation to landâcover type. Successful resource management therefore requires accurate information on yields from alternative vegetation types to adequately address concerns regarding water production. Of particular importance are upper watersheds/catchments, regardless of where water is extracted.
