  2. Autogenic succession - Wikipedia

    en.wikipedia.org/wiki/Autogenic_succession

    The plants themselves (biotic components) cause succession to occur. Light captured by leaves; Production of detritus; Water and nutrient uptake; Nitrogen fixation; anthropogenic climate change; These aspects lead to a gradual ecological change in a particular spot of land, known as a progression of inhabiting species.

  3. Biotic homogenization - Wikipedia

    en.wikipedia.org/wiki/Biotic_Homogenization

    Biotic homogenization is the process by which two or more spatially distributed ecological communities become increasingly similar over time. This process may be genetic, taxonomic, or functional, and it leads to a loss of beta (β) diversity. [1]

  4. 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.

  5. Ecosystem - Wikipedia

    en.wikipedia.org/wiki/Ecosystem

    Such disturbances can cause large changes in plant, animal and microbe populations, as well as soil organic matter content. Disturbance is followed by succession, a "directional change in ecosystem structure and functioning resulting from biotically driven changes in resource supply." [2]: 470

  6. Ecological succession - Wikipedia

    en.wikipedia.org/wiki/Ecological_succession

    Like in plants, microbial succession can occur in newly available habitats (primary succession) such as surfaces of plant leaves, recently exposed rock surfaces (i.e., glacial till) or animal infant guts, [29] and also on disturbed communities (secondary succession) like those growing in recently dead trees, decaying fruits, [39] or animal ...

  7. Biological interaction - Wikipedia

    en.wikipedia.org/wiki/Biological_interaction

    Biotic interactions can vary in intensity (strength of interaction), and frequency (number of interactions in a given time). [ 31 ] [ 32 ] There are direct interactions when there is a physical contact between individuals or indirect interactions when there is no physical contact, that is, the interaction occurs with a resource, ecological ...

  8. Primary succession - Wikipedia

    en.wikipedia.org/wiki/Primary_succession

    One example of primary succession takes place after a volcano has erupted. The lava flows into the ocean and hardens into new land. The resulting barren land is first colonized by pioneer organisms, like algae, which pave the way for later, less hardy plants, such as hardwood trees, by facilitating pedogenesis, especially through the biotic acceleration of weathering and the addition of ...

  9. Biocoenosis - Wikipedia

    en.wikipedia.org/wiki/Biocoenosis

    Biotic communities vary in size, and larger ones may contain smaller ones. Species interactions are evident in food or feeding relationships. A method of delineating biotic communities is to map the food network to identify which species feed upon which others and then determine the system boundary as the one that can be drawn through the ...
