Table 1.

Results of single variable OLS and SAR for the river valley flora and the subnival flora. R2 (or pseudo R 2) and regression coefficients (Coef) are given. Alt_SD = topographic heterogeneity, Cvar_pre = climatic gradient, Modern climate: MAT_pre = annual mean temperature and MAP_pre = annual precipitation, Vel_MAT = climatic fluctuation. ∗P < 0.05, ∗∗P < 0.01, ∗∗∗P < 0.001.
