  1. MAT was mean annual temperature; MAP was mean annual precipitation; Anomaly MAT and Anomaly MAP were glacial-interglacial anomaly in MAT and MAP; ALT Range was altitudinal range; Plant SR was plant species richness. r2 and coefficients (Coef) of ols, Akaike’s information criterion (AIC) and Coef of sar were listed. *p < 0.05, **p < 0.01
