Importance of the selected variables in the PCA ordination axis 1 vs. 2. BIO1 = Annual Mean Temperature (T); BIO2 = Mean Diurnal Range (Mean of monthly (max temp - min temp)); BIO3 = Isothermality (BIO2/BIO7) (×100); BIO5 = Max Temperature of Warmest Month; BIO6 = Min Temperature of Coldest Month; BIO7 = Temperature Annual Range (BIO5–BIO6); BIO8 = Mean Temperature of Wettest Quarter; BIO9 = Mean Temperature of Driest Quarter; BIO10 = Mean Temperature of Warmest Quarter; BIO11 = Mean Temperature of Coldest Quarter; BIO12 = Annual Precipitation (P); BIO15 = Precipitation Seasonality (Coefficient of Variation); BIO16 = Precipitation of Wettest Quarter; BIO17 = Precipitation of Driest Quarter; BIO18 = Precipitation of Warmest Quarter; BIO19 = Precipitation of Coldest Quarter; nfd = number of frost days; dws = drought of the warm season (0BIO18/BIO10); Tp = positive temperature (Rivas-Martínez); Pp = positive precipitation (Rivas-Martínez); Io = (Pp/Tp) × 10 Ombrothermic index by Rivas-Martínez; CI = Coldness Index (Kira).
