  1. The two climate variables correspond to the first two principal components from a PCA on 19 climate variables from BioClim, which explained 60.0 and 31.0 percent of the variance in the data, respectively (see Additional file 1: Table S5 for loadings and Additional file 3: Fig. S2 for relationships among predictor variables)
