Influence of the fast-slow continuum, biomes, and leaf habit on NSC concentrations of (A) roots, (B) stems, (C) branches, and (D) leaves of tropical and temperate tree species. Phylogenetic hierarchical Bayesian models were fitted to examine variation in NSC concentration; points are medians and whisker bars are 80% and 95% credible intervals. Continuous variables were z-transformed prior to analysis to facilitate comparisons (within and across tree organs). Fast-slow PC 1 and fast-slow PC 2 are the first two axes of a principal component analysis of fast-slow plant functional traits. LTF, lowland tropical rainforest; UMF, upper montane forest; and DTF, deciduous temperate forest. Supplementary Table 3 shows trait abbreviations.
