Figure 1. 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) at different plot size. For the 400, 800 and 1200 m2 grain size, we reported the mean percentage of variations explained (PVE), and the standard error, during the 200 sampling of 14 subplots (see Methods). The 2500 m2results were based on models in Table 3. Abbreviations: 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.
