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.

Ecology is a new science and considered as an important branch of biological science, having only become prominent during the second half of the 20th century. [1] Ecological thought is derivative of established currents in philosophy, particularly from ethics and politics.
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 ...
In historical ecology, the landscape is defined as an area of interaction between human culture and the non-human environment. The landscape is a perpetually changing, physical manifestation of history. [17] Historical ecology revises the notion of the ecosystem and replaces it with the landscape.

Population, community, and physiological ecology provide many of the underlying biological mechanisms influencing ecosystems and the processes they maintain. Flowing of energy and cycling of matter at the ecosystem level are often examined in ecosystem ecology, but, as a whole, this science is defined more by subject matter than by scale.
