Table 1.

Minimal mixed-effects models (with standard errors, degrees of freedom, t and P values) for (a) herbivore damage, (b) relative growth rates (RGR) of tree height (mean per species and plot) and (c) RGR of ground diameter (mean per species and plot) across the two sites of the large-scale tree diversity experiment in subtropical China. Estimates were standardized; thus, their magnitude is proportional to the effect size in the final model
