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.
In ecology, a biological interaction is the effect that a pair of organisms living together in a community have on each other. They can be either of the same species (intraspecific interactions), or of different species (interspecific interactions).

Members of these two plant genera are model systems in community genetics research. Community genetics is a recently emerged [citation needed] field in biology that fuses [clarification needed] elements of community ecology, evolutionary biology, and molecular and quantitative genetics.
This is apparent in whole-community facilitation by a foundation species, such as sediment stabilization in cobble beach plant communities by smooth cordgrass. [6] A facilitating species may also help drive the progression from one ecosystem type to another, as mesquite apparently does in the grasslands of the Rio Grande Plains . [ 18 ]
At the beginning of the section "Communal life of organism" of his later book Ecology of Plants (Warming and Vahl 1909), Warming clearly emphasizes the importance of mutual dependence among coexisting species: "The manifold, complex, mutual relations subsisting among organisms are matters of such profound import to plant-life and plant ...
An ecological metacommunity is a set of interacting communities which are linked by the dispersal of multiple, potentially interacting species. [1] [2] [3] The term is derived from the field of community ecology, which is primarily concerned with patterns of species distribution, abundance and interactions.
In other words, it is an assemblage of fossils or a community of specific time, which is different from "death assemblages" (thanatocoenoses). [2] No palaeontological assemblage will ever completely represent the original biological community (i.e. the biocoenosis, in the sense used by an ecologist ); the term thus has somewhat different ...
