Explain the Ecological niche modelling?

The geographic range of organisms frequently reflects their fundamental niche, the range of physical conditions where they can live. Quantitative biologists should applied genetic algorithms, a comparatively new statistical method, to synthesize large data sets that contain the locations and physical conditions where a specific species has ever been found and come up with rules for extrapolating these requirements across space and time. These techniques can be used to infer where populations of a given species may be found; to predict the ultimate limits of invading species; or to predict the modifications in geographic range with future natural or anthropogenic climate change.
