	Ecology - Wikipedia, the free encyclopedia
		Ecology, or ecological science, is the scientific study of the distribution and abundance of living organisms and how the distribution and abundance are affected by interactions between the organisms and their environment.
		Ecosystem ecology studies the flows of energy and matter through the biotic and abiotic components of ecosystems.
		The ecosystem is composed of two entities, the entirety of life, the biocoenosis and the medium that life exists in the biotope.

	Ecosystem ecology - Wikipedia, the free encyclopedia
		Ecosystem ecology is the study of the movement of energy and matter through ecosystems.
		It is one of the fundamental disciplines of ecology.
		Ecosystem ecology operates at a scale above that of communities but it is defined more by subject matter than by scale.

	Institute of Ecosystem Studies Definition of Ecology (Site not responding. Last check: 2007-11-04)
		Ecology is the scientific study of the processes influencing the distribution and abundance of organisms, the interactions among organisms, and the interactions between organisms and the transformation and flux of energy and matter.
		In an ordination based on spatial scale, landscape ecology might appear between the biome scale at which "macroecology" is practiced, and the watershed scale (Likens 1992) at which ecosystem ecology is often practiced.
		Ecology is shown as a continuum of specialties ordered by increasing proportion of attention devoted to the physical environment compensated for by decreasing focus on biotic features.

	Ecosystem Ecology
		The ecosystem is affected by energy flow and chemical cycling.
		In agricultural ecosystems, a large amount of nutrients are removed from the area in the crop biomass.
		Combustion of fossil fuels is the main cause of acid precipitation The burning of fossil fuels releases sulfur oxides and nitrogen that react with water in the atmosphere to produce sulfuric and nitric acids.

	Ecology
		Contemporary ecology consists of a patchwork of sub-disciplines including population ecology, community ecology, conservation ecology, ecosystem ecology, metapopulation ecology, metacommunity ecology, spatial ecology, landscape ecology, physiological ecology, evolutionary ecology, functional ecology, and behavioral ecology.
		Ecosystem enthusiasts follow a long holistic tradition in natural history that tends to deify complexity and deny the possibility of explaining wholes in terms of their parts.
		In the type of population ecology that was discussed earlier (in Section 2), populations were characterized by their state variables, parameters such as size or density describing the population as a whole and—with two exceptions—ignoring individual differences.

	Association Ecosystem : Field Ecology Education
		Association "Ecosystem" was founded in 1994 by a group of young biologists and educators, the former participants of the biological school group of the state Darwin Museum in Moscow.
		The main activity of "Ecosystem" is an introduction of outdoor ideology and approach into the environmental education system, emphasizing children's involvement with concrete research work and nature conservation through different types of outdoor activities.
		Nowadays "Ecosystem" is an instructive-methodical center for the environmental education of school-children.

	ECOSYSTEM ECOLOGY
		Ecosystems are conceived as units of nature that control and regulate energy flow and nutrient availability.
		Often we hear that ecosystems need to be studied with a "holistic" approach (meaning they need to be studied as intact units rather than using procedures that take them apart and study them piece by piece).
		In this course I hope to introduce you to the ecosystem concept, the problems encountered in studying "ecosystems" and some of the approaches that have been taken to address these problems.

	3.4. Ecosystem Ecology (Site not responding. Last check: 2007-11-04)
		An ecosystem is the community of organisms in an area and their non-living environment (Figure 1).
		The concept of communities interacting with their physical environment such as dead matter, minerals, water; and energy is the basis of ecology.
		The goal of crop production is to maximize ecosystem energy into a harvestable product; utilization of plant energy by pests is undesirable as it takes away from crop production.

	ecology: The Ecosystem
		An ecosystem may be as small as a tidal pool or a rotting log or as large as an ocean or a continent-spanning forest.
		Each ecosystem consists of a community of plants and animals in an environment that supplies them with raw materials for life, i.e., chemical elements and water.
		The ecosystem is delimited by the climate, altitude, water and soil characteristics, and other physical conditions of the environment.

		Thus, Eugene was exposed to ecology from the start, and the large group of graduate students in the department provided the opportunity to discuss the most exciting ideas of the time.
		Odum later remarked that his transition from the physiology of the individual to ecosystems was a natural one, since as he put it, its not such a big step to go from physiology on one level to physiology on the ecosystem level.
		Bormann and Likens showed that big time ecology could be done without having to have a large infrastructure, and that for studies concerned with biogeochemical cycling, that the watershed was the ideal unit.

		Ecosystem ecologists are interested in two main topics: the flow of energy through ecosystems and the cycling of nutrients.
		Ultimately, all ecosystems depend on the sun for energy.
		Ecosystems do not usually have more than five levels because little energy is available to support fifth-level consumers (because 10% is lost at each level).

	Origins of Ecosystem Ecology - Part2 (Site not responding. Last check: 2007-11-04)
		Hutchinson thought that ecology encompassed a variety of subjects, ranging from the biological to the purely physical, and that a biogeochemical approach was one way to unify these two poles of research, coupled with a demographic approach, which concentrated on population dynamics and the factors regulating them.
		What Tansley proposed in his ecosystem concept can be broken down into three major parts: 1) it is an element in a hierarchy of physical systems, 2) it is the basic unit of ecology, and 3) composed of both the organism-complex and the physical-environmental complex.
		During the conceptualization of his Ph.D. thesis, Lindemann concluded that the lake was an ecosystem in the sense that Tansley meant it to be used.
