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.
[1]: 181 The term was first coined by Alexander von Humboldt [1]: 16 and formalised by the International Botanical Congress in 1910. [1]: 182 [2] An association can be viewed as a real, integrated entity shaped either by species interactions or by similar habitat requirements, or it can be viewed as merely a common point along a continuum.
The classification system has four levels, but only Levels I and III are on this list. Level I divides North America into 15 broad ecoregions; of these, 12 lie partly or wholly within the United States. Fifty Level II regions were created to allow for a narrower delineation of Level I areas. Three level I areas were not subdivided for level 2. [2]
Ecological classification or ecological typology is the classification of land or water into geographical units that represent variation in one or more ecological features. . Traditional approaches focus on geology, topography, biogeography, soils, vegetation, climate conditions, living species, habitats, water resources, and sometimes also anthropic factors.
A plant community can be rare even if none of the major species defining it are rare. [1]: 115 This is because it is the association of species and relationship to their environment that may be rare. [1]: 115 An example is the sycamore alluvial woodland in California dominated by the California sycamore Platanus racemosa.
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.
Community would be the collective dynamics amongst species and the habitat in which they live in. [6] Communities are most closely associated with habitats, which are more intimate than compared to ecosystems. Habitats signify a smaller, more specific region, while an ecosystem is a broader term that can encompass multiple habitats.
In scientific ecology, climax community or climatic climax community is a historic term for a community of plants, animals, and fungi which, through the process of ecological succession in the development of vegetation in an area over time, have reached a steady state. This equilibrium was thought to occur because the climax community is ...
