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 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 ...
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.
Ecology overlaps with the closely related sciences of biogeography, evolutionary biology, genetics, ethology, and natural history. Ecology is a branch of biology, and is the study of abundance, biomass, and distribution of organisms in the context of the environment.
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 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.
Ecological facilitation or probiosis describes species interactions that benefit at least one of the participants and cause harm to neither. [1] Facilitations can be categorized as mutualisms, in which both species benefit, or commensalisms, in which one species benefits and the other is unaffected.
