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.
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.
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).
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. The environmental data are most ...
Developmental niche, a concept for understanding the cultural context of child development Ecological niche , a term describing the relational position of an organism's species Niche differentiation , in ecology, the process by which competing species use the environment differently in a way that helps them to coexist
The most notable definition of a vacant niche is that of the ecologist K. Rohde, who has suggested that a vacant niche can be defined as the possibility that in ecosystems or habitats more species could exist than are present at a particular point in time, because many possibilities are not used by potentially existing species.
The Eltonian niche is an ecological niche that emphasizes the functional attributes of animals and their corresponding trophic position. This was the definition Eugene Odum popularized in his analogy of the niche of a species with its profession in the ecosystem as opposed to the habitat being its address.
In an influential paper, Wiens and Donoghue [3] laid out how phylogenetic niche conservatism might help explain the latitudinal diversity gradient.While support for the hypothesis that niche conservatism drives latitudinally structured variation in species richness has been found in some clades, [11] overall, phylogenetic niche conservatism has not received strong support as the underlying ...
