Figure 2.

Standardized effect size (SES) of T‐statistics (see figure legend) of LMA along the (A) vegetation and elevation gradients for (B) sun and (C) shade leaves. Here, for each community or plot, we report three observed and null T‐statistics: (1) the ratio of the trait variance of individuals in species groups to the trait variance of individuals in the local community (T_ip.ic, dark shaded box); (2) the ratio of trait variance of individuals in the local community to the trait variance of the individual in the whole regional pool (T_ic.ir, striped dark gray box); and (3) the ratio of the species trait variance in the local community to the species trait variance in the regional pool (T_pc.pr, solid light gray box). Each filled dot represents the mean SES value for one community (plot) compared to the null model expectation. Boxes indicate the confidence interval of the null model for each T‐statistic. The SES are significantly different from the null distribution if not embedded within the box. The lower the SES value compared to the null model, the stronger the filter.
