Bioclim 1- Bioclim 19 = Bioclimatic variables as per definition on http://www.worldclim.org/bioclim (see Table 2); ns = non-significant; levels marked with different letters indicate significant difference among cluster averages (p<0.05) based on the Tukey HSD test. Numbers in brackets after p values indicate the two clusters being compared.
