The regression lines between PC2 scores and bioclimate variables: the mean temperature of the coldest quarter (BIO 11) and mean precipitation of the wettest quarter (BIO 16). The color map of the cranial surface at the top of the graph indicates vertices highly correlated with PC2. Virtual shapes with PC2 scores of ± 3 SD are also shown. The scale is given as a green colored sphere with a diameter of 50 mm. Abbreviations: see Tables 1 and 2.
