Figure S3. Variation partitioning analysis for the relative importance of stand factors vs. diversity in explaining forest biomass (A), productivity (B) and their stability (C and D, respectively). Different from Fig. 1, results here were based on models in Table 3, which differed markedly in sample size among grain sizes. PVE (%), percentage of variations explained; Diver_T, Diver_P, Stand_T and Stand_P, the total and pure effect of diversity indices, and the total and pure effect of stand factors, respectively.
