Species distribution models (SDMs) are numerical tools that combine observations of species occurrence or abundance with environmental estimates. They are used to gain ecological and evolutionary insights, predict distributions across landscapes and sometimes are extrapolated in space and time. SDMs are now widely used in terrestrial, freshwater, and marine ecological studes. Differences in methos among disciplines reflect both differences in species mobility and in ´established use´. Model realism and robustness are influenced by selection of relevant predictors (climatic variables, geological substrate, slope and orientation, etc.), by modeling method (usually MaxEnt program, but other models are also used), spatial scale considered (region, country, continent), and the extent of extrapolation (i.e., how far we extrapolate from the sites where the data we colllected). Biologically speaking, SDMs enable the prediction of the occurrence of a species based on a set of GPS coordinates of known sites and a set of biotic and abiotic characteristics of these sites.
