Table 3. The mean ± standard deviation of the percent of contribution and permutation importance of the explanatory variables to the SDMs of each species and subspecies. The percent of contribution is the gain of the model by including a given environmental covariate at each step of the Maxent algorithm. The permutation importance is the influence of each environmental covariate on the final model, measured through the random permutation of the values of such covariate among the training points and measuring the resulting decrease in the training area under the curve.
