According to Figure 3 , the PLS-PM analysis results showed that geography (LAT and LON) had a significantly positive correlation (path coefficient=0.37, p=0.07 with a considerable trend toward significance) with leaf stoichiometry (leaf P concentration and N:P ratio), a significantly positive association (path coefficient=0.81, p<0.001) with climate (MAT and MAP), and a significantly positive association (path coefficient=0.75, p<0.001) with soil (TN, TP, and soil N:P ratio).
