The total of a species’ use of biotic and abiotic resources is called the species’ ecological niche . An ecological niche can also be thought of as an organism’s ecological role. No two species can have the same ecological niche. The niche is affected by biotic and abiotic factors. Many of them are also animated. Ecological niche modeling (and the related species distribution modeling) represents an effort to estimate dimensions of the fundamental ecological niche, and therefore, it can predict the probability of environmental suitability for a species in an area (Cardona and Loyola 2008, Peterson et al.
