Summary statistics of predictive accuracy for the different models.

TSS-true skill statistic and AUC-the area under the receiver operating characteristic curve; climate SDM-species-distribution model using only climate variables; edaphic SDM-species distribution model using only edaphic predictors; edaphic-climate SDM-species distribution model using both edaphic and climate predictors. Reported are means for all species for each statistical model type, ± one standard deviation, and percentage of species with a AUC greater than 0.80 or a TSS greater than 0.60; for cross validation models, the mean of each species was first calculated
