A bear with a salmon. Interspecific interactions such as predation are a key aspect of community ecology.. In ecology, a community is a group or association of populations of two or more different species occupying the same geographical area at the same time, also known as a biocoenosis, biotic community, biological community, ecological community, or life assemblage.
Community ecology is the study of the interactions among a collection of species that inhabit the same geographic area. Community ecologists study the determinants of patterns and processes for two or more interacting species. Research in community ecology might measure species diversity in grasslands in relation to soil fertility. It might ...
According to a widespread narrative, the ideas of a holistic ecological community were introduced by plant ecologist Frederic Clements in 1916, and countered by Henry Gleason in 1917, when he proposed the individualistic/open community concept (in applications to plants). [1] However, this seems to be wrong in at least two essential respects:

Human ecology is an interdisciplinary and transdisciplinary study of the relationship between humans ... Polis stems from its Greek roots for a political community ...
Cultural ecology as developed by Steward is a major subdiscipline of anthropology. It derives from the work of Franz Boas and has branched out to cover a number of aspects of human society, in particular the distribution of wealth and power in a society, and how that affects such behaviour as hoarding or gifting (e.g. the tradition of the potlatch on the Northwest North American coast).
In phytosociology and community ecology an association is a type of ecological community with a predictable species composition and consistent physiognomy (structural appearance) which occurs in a particular habitat type.
A plant community is a collection or association [1] [page needed] of plant species within a designated geographical unit, which forms a relatively uniform patch, distinguishable from neighboring patches of different vegetation types. The components of each plant community are influenced by soil type, topography, climate and human disturbance ...
