Predicted distribution of suitable climate for the North American vaejovid scorpion Pseudouroctonus reddelli, produced by an ensemble of 20 species distribution models. Models were the product of the factorial combination of four modelling algorithms with five sets of uncorrelated variables. Dots indicate the locations of 25 surface occurrences for P. reddelli used to develop distribution models. Colours indicate the number of models that predict the presence of suitable climate at present, as represented in gridded layers from WorldClim (a), and during the Last Glacial Maximum, as represented by the CCSM (b) and MIROC (c) general circulation models.
