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.

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.

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 ...
Ecosystem model. A structural diagram of the open ocean plankton ecosystem model of Fasham, Ducklow & McKelvie (1990). [1] An ecosystem model is an abstract, usually mathematical, representation of an ecological system (ranging in scale from an individual population, to an ecological community, or even an entire biome), which is studied to ...
Environmental modelling. Environmental modelling is the creation and use of mathematical models of the environment. Environmental modelling may be used purely for research purposes, and improved understanding of environmental systems, or for providing an interdisciplinary analysis that can inform decision making and policy.
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.
