  2. Occupancy–abundance relationship - Wikipedia

    en.wikipedia.org/wiki/Occupancy–abundance...

    Niche dynamics assume differences among species in their fundamental niche which should give rise to patterns in the abundance and distribution of species (i.e. their realized niches). In this framework, the abundance and distribution of a single species and hence the emergent patterns across multiple species, are driven by causal mechanisms ...

  3. Ecological niche - Wikipedia

    en.wikipedia.org/wiki/Ecological_niche

    Hutchinson's "niche" (a description of the ecological space occupied by a species) is subtly different from the "niche" as defined by Grinnell (an ecological role, that may or may not be actually filled by a species—see vacant niches). A niche is a very specific segment of ecospace occupied by a single species.

    Realized niche width is a phrase relating to ecology, is defined by the actual space that an organism inhabits and the resources it can access as a result of limiting pressures from other species (e.g. superior competitors).

  6. Niche market - Wikipedia

    en.wikipedia.org/wiki/Niche_market

    A niche market is the subset of the market on which a specific product is focused. The market niche defines the product features aimed at satisfying specific market needs, as well as the price range, production quality and the demographics that it is intended to target. It is also a small market segment. Sometimes, a product or service can be ...

  7. Niche apportionment models - Wikipedia

    en.wikipedia.org/wiki/Niche_apportionment_models

    Mechanistic models of niche apportionment are intended to describe communities. Researchers have used these models in many ways to investigate the temporal and geographic trends in species abundance. For many years the fit of niche apportionment models was conducted by eye and graphs of the models were compared with empirical data. [5]

  8. Niche construction - Wikipedia

    en.wikipedia.org/wiki/Niche_construction

    Niche construction is the ecological process by which an organism alters its own (or another species') local environment. These alterations can be a physical change to the organism’s environment, or it can encompass the active movement of an organism from one habitat to another where it then experiences different environmental pressures.
