Fig. 4 Structural Equation Model-fit path summary relating AGB
to species richness via functional evenness and structural diversity
metrics (Significant paths (P < 0.05) are represented
with solid arrows and non-significant paths (P >
0.05) by dashed arrows. The single-pointed arrows represent causal paths
and double-pointed arrows the residual correlations. The values without
parentheses are the standardized path coefficients. The values with
parentheses are the coefficients of determination. CV DBH: tree diameter
variation; CV Nbp: variation of number of primary branches. Detailed
statistics are shown in Tables 2-3.
