  2. Community (ecology) - Wikipedia

    en.wikipedia.org/wiki/Community_(ecology)

    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.

  3. Biocoenosis - Wikipedia

    en.wikipedia.org/wiki/Biocoenosis

    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 ...

  4. Ecological classification - Wikipedia

    en.wikipedia.org/wiki/Ecological_classification

    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.

  5. Ethnoecology - Wikipedia

    en.wikipedia.org/wiki/Ethnoecology

    Ecology is the study of the interactions between living organisms and their environment; enthnoecology applies a human focused approach to this subject. [2] The development of the field lies in applying indigenous knowledge of botany and placing it in a global context.

  6. List of ecoregions in the United States (EPA) - Wikipedia

    en.wikipedia.org/wiki/List_of_ecoregions_in_the...

    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]

  7. Association (ecology) - Wikipedia

    en.wikipedia.org/wiki/Association_(ecology)

    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.

  8. Outline of ecology - Wikipedia

    en.wikipedia.org/wiki/Outline_of_ecology

    Ecology can also be classified on the basis of: . the primary kinds of organism under study, e.g. animal ecology, plant ecology, insect ecology; the biomes principally studied, e.g. forest ecology, grassland ecology, desert ecology, benthic ecology, marine ecology, urban ecology;

  9. Ecological unit - Wikipedia

    en.wikipedia.org/wiki/Ecological_unit

    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.
