  2. Ecological niche - Wikipedia

    en.wikipedia.org/wiki/Ecological_niche

    Once a niche is left vacant, other organisms can fill that position. For example, the niche that was left vacant by the extinction of the tarpan has been filled by other animals (in particular a small horse breed, the konik). Also, when plants and animals are introduced into a new environment, they have the potential to occupy or invade the ...

  3. Competition (biology) - Wikipedia

    en.wikipedia.org/wiki/Competition_(biology)

    An example among animals could be the case of cheetahs and lions; since both species feed on similar prey, they are negatively impacted by the presence of the other because they will have less food, however, they still persist together, despite the prediction that under competition one will displace the other. In fact, lions sometimes steal ...

  4. Interspecific competition - Wikipedia

    en.wikipedia.org/wiki/Interspecific_competition

    Niche separation of species, local extinction and competitive exclusion are only some of the possible effects. In addition to these, interspecific competition can be the source of a cascade of effects that build on each other. An example of such an effect is the introduction of an invasive species to the United States, purple-loosestrife. This ...

  5. Ecosystem diversity - Wikipedia

    en.wikipedia.org/wiki/Ecosystem_diversity

    An example of ecological diversity on a global scale would be the variation in ecosystems, such as deserts, forests, grasslands, wetlands and oceans. Ecological diversity is the largest scale of biodiversity, and within each ecosystem, there is a great deal of both species and genetic diversity .

  6. Niche construction - Wikipedia

    en.wikipedia.org/wiki/Niche_construction

    Niche construction can also generate co-evolutionary interactions, as illustrated by the above earthworm, beaver and yeast examples. The development of many organisms, and the recurrence of traits across generations, has been found to depend critically on the construction of developmental environments such as nests by ancestral organisms.

  7. Competitive exclusion principle - Wikipedia

    en.wikipedia.org/wiki/Competitive_exclusion...

    For example, a slight modification of the assumption of how growth and body size are related leads to a different conclusion, namely that, for a given ecosystem, a certain range of species may coexist while others become outcompeted. [10] [11] One of the primary ways niche-sharing species can coexist is the competition-colonization trade-off ...

  8. 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.

  9. Character displacement - Wikipedia

    en.wikipedia.org/wiki/Character_displacement

    For example, Joseph Grinnell, in the classic paper that set forth the concept of the ecological niche, stated, "It is, of course, axiomatic that no two species regularly established in a single fauna have precisely the same niche requirements."
