Extended Data Fig. 5: Comparison between predicted θ with field-based studies.
From: Drought resistance enhanced by tree species diversity in global forests
The blue bars show the number of sites using δ13C change to measure drought resistance at both tree and ecosystem levels (Δδ13C), using changes in annual tree rings to measure drought resistance at the tree level (Growth, Tree level) and using changes in annual tree rings at the ecosystem scale (Growth, Ecosystem level). The red bars show the number of sites where the sign of predicted θ is consistent with that of documented species diversity effect from field studies. The data used in this plot are listed in Supplementary Table 2.
