Figure S1 Results from the PCA of climate variables and altitude. The first axis (PC1) explains 50.36% of
the variance and reflects a gradient of aridity, while the second one (PC2) explains 32.26% and
reproduces a thermicity gradient. Codes of climate and altitude variables used in the PCA to define
principal climate trends are listed below the scatterplot. The codes for monthly average temperatures and
precipitation are followed by the number of the given month (i.e, 1 for January, 2 for February, etc.).
