For the interpretation of results (Grace et al., 2016), we conducted
bivariate relationships between aboveground biomass and predictors
(species diversity, DBH variation and CEC). We also test the relationship
of CEC with each of species diversity and DBH variation, according to our
hypothetical paths in SEM. We used boxplots, one-way ANOVA test
with Tukey's test, in order to evaluate the distributions and significant
differences of aboveground biomass, DBH variation and species diversity
among levels of stand quality.
