  2. Ecological niche - Wikipedia

    en.wikipedia.org/wiki/Ecological_niche

    Ecological niche. Appearance. The flightless dung beetle occupies an ecological niche: exploiting animal droppings as a food source. In ecology, a niche is the match of a species to a specific environmental condition. [ 1 ][ 2 ] It describes how an organism or population responds to the distribution of resources and competitors (for example, by ...

  3. Generalist and specialist species - Wikipedia

    en.wikipedia.org/wiki/Generalist_and_specialist...

    A benefit of a specialist species is that because the species has a more clearly defined niche, this reduces competition from other species. On the other hand, generalist species, by their nature, cannot realize as much resources from one niche, but instead find resources from many. Because other species can also be generalists, there is more ...

  4. Niche construction - Wikipedia

    en.wikipedia.org/wiki/Niche_construction

    Niche construction. Beavers hold a very specific biological niche in the ecosystem: constructing dams across river systems. 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 ...

  5. Interspecific competition - Wikipedia

    en.wikipedia.org/wiki/Interspecific_competition

    The two species share the same ecological niche, and are thus in competition with each other. Interspecific competition, in ecology, is a form of competition in which individuals of different species compete for the same resources in an ecosystem (e.g. food or living space). This can be contrasted with mutualism, a type of symbiosis.

  6. Realized niche width - Wikipedia

    en.wikipedia.org/wiki/Realized_niche_width

    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). An organism's ecological niche is determined by the biotic and abiotic factors that make up that specific ecosystem that ...

  7. Relative species abundance - Wikipedia

    en.wikipedia.org/wiki/Relative_species_abundance

    Relative species abundance is a component of biodiversity and is a measure of how common or rare a species is relative to other species in a defined location or community. [1] Relative abundance is the percent composition of an organism of a particular kind relative to the total number of organisms in the area. [citation needed]

  8. Species distribution modelling - Wikipedia

    en.wikipedia.org/wiki/Species_Distribution_Modelling

    Species distribution modelling (SDM), also known as environmental (or ecological) niche modelling (ENM), habitat modelling, predictive habitat distribution modelling, and range mapping[1] uses ecological models to predict the distribution of a species across geographic space and time using environmental data.

  9. Ecotype - Wikipedia

    en.wikipedia.org/wiki/Ecotype

    An ecotype is a variant in which the phenotypic differences are too few or too subtle to warrant being classified as a subspecies. These different variants can occur in the same geographic region where distinct habitats such as meadow, forest, swamp, and sand dunes provide ecological niches. Where similar ecological conditions occur in widely ...
