OEcology \[OE]*col"o*gy\ ([-e]*k[o^]l"[-o]*j[y^]), n. [Gr. o'i^kos house + -logy.] (Biol.) The various relations of animals and plants to one another and to the outer world; -- now more commonly spelled ecology. [Also spelled ecology.]


ecology \ecology\ ([-e]*k[o^]l"[-o]*j[y^]), n. [Gr. o'i^kos house + -logy.] (Biol.) the branch of biology concerned with the various relations of animals and plants to one another and to their surrounding environment.

Douglas Harper's Etymology Dictionary

1873, oecology, "branch of science dealing with the relationship of living things to their environments," coined in German by German zoologist Ernst Haeckel (1834-1919) as Ökologie, from Greek oikos "house, dwelling place, habitation" (see villa) + -logia "study of" (see -logy). In use with reference to anti-pollution activities from 1960s.


n. The branch of biology dealing with the relationships of organisms with their environment and with each other.

  1. n. the environment as it relates to living organisms; "it changed the ecology of the island"

  2. the branch of biology concerned with the relations between organisms and their environment [syn: bionomics, environmental science]

Ecology (disciplines)

Ecology is a broad biological science and can be divided into many sub-disciplines using various criteria. Many of these fields overlap, complement and inform each other, and few of these disciplines exist in isolation. For example, the population ecology of an organism is a consequence of its behavioral ecology and intimately tied to its community ecology. Methods from molecular ecology might inform the study of the population, and all kinds of data are modeled and analyzed using quantitative ecology techniques.

When discussing the study of a single species, a distinction is usually made between its biology and its ecology. For example, " polar bear biology" might include the study of the polar bear's physiology, morphology, pathology and ontogeny, whereas "polar bear ecology" would include a study of its prey species, its population and metapopulation status, distribution, dependence on environmental conditions, etc. In that sense, there can be as many subdisciplines of ecology as there are species to study.

Ecology (journal)

Ecology is a scientific journal publishing research and synthesis papers in the field of ecology. It was founded in 1920, and is published by the Ecological Society of America. It is currently ranked 15th out of 136 journals in the category "ecology" according to the Journal Citation Reports.

Ecology (album)

Ecology is the third studio album by classic rock band Rare Earth. It was released in 1970 on Rare Earth Records.

Ecology (disambiguation)

Ecology is the scientific study of the distribution and abundance of organisms and their interactions with their environment.

Ecology or may also refer to:


Ecology (from , "house", or "environment"; -λογία, "study of") is the scientific analysis and study of interactions among organisms and their environment. It is an interdisciplinary field that includes biology, geography, and Earth science. Ecology includes the study of interactions organisms have with each other, other organisms, and with abiotic components of their environment. Topics of interest to ecologists include the diversity, distribution, amount ( biomass), and number ( population) of particular organisms, as well as cooperation and competition between organisms, both within and among ecosystems. Ecosystems are composed of dynamically interacting parts including organisms, the communities they make up, and the non-living components of their environment. Ecosystem processes, such as primary production, pedogenesis, nutrient cycling, and various niche construction activities, regulate the flux of energy and matter through an environment. These processes are sustained by organisms with specific life history traits, and the variety of organisms is called biodiversity. Biodiversity, which refers to the varieties of species, genes, and ecosystems, enhances certain ecosystem services.

Ecology is not synonymous with environment, environmentalism, natural history, or environmental science. It is closely related to evolutionary biology, genetics, and ethology. An important focus for ecologists is to improve the understanding of how biodiversity affects ecological function. Ecologists seek to explain:

  • Life processes, interactions, and adaptations
  • The movement of materials and energy through living communities
  • The successional development of ecosystems
  • The abundance and distribution of organisms and biodiversity in the context of the environment.

Ecology is a human science as well. There are many practical applications of ecology in conservation biology, wetland management, natural resource management ( agroecology, agriculture, forestry, agroforestry, fisheries), city planning ( urban ecology), community health, economics, basic and applied science, and human social interaction ( human ecology). For example, the Circles of Sustainability approach treats ecology as more than the environment 'out there'. It is not treated as separate from humans. Organisms (including humans) and resources compose ecosystems which, in turn, maintain biophysical feedback mechanisms that moderate processes acting on living ( biotic) and non-living ( abiotic) components of the planet. Ecosystems sustain life-supporting functions and produce natural capital like biomass production (food, fuel, fiber, and medicine), the regulation of climate, global biogeochemical cycles, water filtration, soil formation, erosion control, flood protection, and many other natural features of scientific, historical, economic, or intrinsic value.

The word "ecology" ("Ökologie") was coined in 1866 by the German scientist Ernst Haeckel (1834–1919). Ecological thought is derivative of established currents in philosophy, particularly from ethics and politics. Ancient Greek philosophers such as Hippocrates and Aristotle laid the foundations of ecology in their studies on natural history. Modern ecology became a much more rigorous science in the late 19th century. Evolutionary concepts relating to adaptation and natural selection became the cornerstones of modern ecological theory.
