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.
Ecological niche. 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 growing when ...
Niche models are a notable class of CRMs which are described by the system of coupled ordinary differential equations, [7] [8] = (), =, …,, = + = (), =, …,, where (, …,) is a vector abbreviation for resource abundances, is the per-capita growth rate of species , is the growth rate of species in the absence of consumption, and is the rate per unit species population that species depletes ...
A GARP model is a random set of mathematical rules which can be read as limiting environmental conditions. Each rule is considered as a gene; the set of genes is combined in random ways to further generate many possible models describing the potential of the species to occur. See also.

This model describes a situation where after initial colonization (or speciation) each new species pre-empts more than 50% of the smallest remaining niche. In a Dominance preemption model of niche apportionment the species colonize random portion between 50 and 100% of the smallest remaining niche, making this model stochastic in nature.

Limiting similarity. Limiting similarity (informally "limsim") is a concept in theoretical ecology and community ecology that proposes the existence of a maximum level of niche overlap between two given species that will allow continued coexistence. This concept is a corollary of the competitive exclusion principle, which states that ...
