AWB is aboveground woody biomass; ABP is aboveground biomass production. pd is phylogenetic diversity; mntd is the mean nearest taxon distance; sr is species richness; FEve is functional evenness; FDis is functional dispersion; FDiv is functional divergence. CWM_LC is community-level weighted means of leaf carbon content; CWM_Hmax is community-level weighted means of the maximum tree height; CWM_LA is community-level weighted means of leaf area; CWM_SLA is community-level weighted means of specific leaf area
