Fig. 2. The best-fit SEM relating aboveground biomass to stand quality, CEC, DBH variation,
and species diversity. Solid arrows represent significant (P b 0.05) paths and dashed
arrows represent non-significant paths (P N 0.05). For each path the standardized
regression coefficient is shown. R2 indicates the total variation in a dependent variable
that is explained by the combined independent variables. The model fit statistics
summary is provided.
