  Ecological Anthropology
Ecological anthropology investigates the ways that a population shapes its environment and the subsequent manners in which these relations form the population’s social, economic, and political life (Salzman and Attwood 1996:169).
Ecological anthropology is also a reaction to idealism, which is the idea that all objects in nature and experience are representations of the mind.
Ecological anthropology contributes to the development of extended models of sustainability for humankind.

  Ecology - New World Encyclopedia Preview
Ecological factors that can affect dynamic change in a population or species in a given ecology or environment are usually divided into two groups: biotic and abiotic.
Lastly, an ecological crisis may be local (an oil spill, a fire, or eutrophication of a lake), widespread (the movement of glaciers during an ice age), or global (a rise in the sea level).
Ecological succession is the process by which a natural community moves from a simpler level of organization to a more complex community (e.g., from bare sand, to grass growing on the sand, to grass growing on dirt produced from dead grass, to trees growing in the dirt produced by the grass).

 Society for Ecological Restoration International
Ecological restoration is an intentional activity that initiates or accelerates the recovery of an ecosystem with respect to its health, integrity and sustainability.
Accordingly, it is not surprising that interest in ecological restoration is growing rapidly worldwide and that, in most cases, cultural beliefs and practices are drawn upon to help determine and shape of what is to be performed under the rubric of restoration.
Ecological processes or ecosystem functions are the dynamic attributes of ecosystems, including interactions among organisms and interactions between organisms and their environment.

 ESA journals -- Ecological Applications
Ecological Applications occasionally publishes Forums.  A Forum can take a number of forms but always includes a series of commentaries solicited from a number of experts.  These commentaries represent personal responses to a paper (or papers) considered to be of very broad interest and significance within the field of applied ecology. Special instructions are available.
Ecological Applications seeks to publish papers that will be interesting to a diverse audience including readers from many different subdisciplines of ecology, as well as from related disciplines.
Given the focus of the journal on applications of ecological science to environmental problems, readers also include land managers, environmental consultants, ecologists with state and federal agencies, ecologists working for industry, and many others who are not necessarily heavily involved in doing research themselves.

 NatureServe: A Working Classification of Terrestrial Ecological Systems in the Coterminous U.S.
Ecological systems represent recurring groups of biological communities that are found in similar physical environments and are influenced by similar dynamic ecological processes, such as fire or flooding.
Terrestrial ecological systems are specifically defined as a group of plant community types (associations) that tend to co-occur within landscapes with similar ecological processes, substrates, and/or environmental gradients.
The multiple ecological factors are evaluated and combined in different ways to explain the spatial co-occurrence of plant associations.

 Ecological Footprint -- Revisiting Carrying Capacity: Area-Based Indicators of Sustainability
In ecological terms, all our toys and tools (the "capital" of economists) are "the exosomatic equivalent of organs" (Sterrer, 1993) and, like bodily organs, require continuous flows of energy and material to and from "the environment" for their production and operation.
Ecological Footprint - The corresponding area of productive land and aquatic ecosystems required to produce the resources used, and to assimilate the wastes produced, by a defined population at a specified material standard of living, wherever on Earth that land may be located.
Ecological deficits are a measure of the entropic load and resultant "disordering" being imposed on the ecosphere by so-called advanced countries as the unaccounted cost of maintaining and further expanding their wealthy consumer economies.

 ECOLOGICAL ECONOMICS
Ecological economics is a policy-oriented perspective that addresses the interdependence and coevolution between human economies and their natural ecosystems.
Ecological economics is positive, in its development of understanding of the physical, biological and social structural and functional relations between economies and natural ecosystems.
The ecological economics problem is to address the potential willful capacity of humans to alter their own relatively unknown environment to such an extent that they can adversely impact their own current or future welfare.

 Ministry of Environment - Ecological Reserves
Ecological reserves are areas selected to preserve representative and special natural ecosystems, plant and animal species, features and phenomena.
A full-time ecological reserve coordinator was hired in 1974, regulations related to use and protection of the reserves were enacted in 1975, and a volunteer warden program put into effect in 1980.
Ecological reserves also offer opportunities for a wide range of educational activities ranging from simple observation and nature interpretation to the teaching of complex ecological processes.

 Ecological Effects
This practice is both economically and ecologically unsound, since it would deprive all plants in the area of pollinators and disrupt control of plant pests by their natural enemies.
Long-term studies and monitoring of ecological effects of new and existing chemicals released into the environment are needed in order to create understanding of potential adverse ecological effects and their consequences.
Hence, ecological effects are of serious concern in regulating pollutants and a variety of tests have been devised to help evaluate the potential for adverse ecological effects.

 Circular 1112 -- Ecological Studies
Ecological Studies are an integral part of the approach used by NAWQA to assess water quality.
The unit of sampling for Ecological Studies is the sampling reach, which is a part of the stream where stream, bank, and flood-plain habitat features are representative of the local area, and near the fixed-site location where chemical data are collected.
Priorities for Ecological Synoptic Studies are evaluated based on the potential to address relations among physical, chemical, and biological characteristics; the areal extent of a water-quality problem or biological issue; and the degree to which the design contributes to regional understanding and current National Synthesis topics.

 ecological
A mathematical statement of the ratio between the energy available to an organism or group or group processes, and the energy actually expended.
For example, a bear may use less calories to hunt a rabbit during the summer than the calories gained from the rabbit, but winter hunting expends more than is gained, so it is more ecologically efficient for bears to hibernate.
A 10 percent gain is average, 20 percent very good, 5 percent typical of the top of the food chain.
