The results summarize a linear ANCOVA model relating the predicted to the observed values in stem density, basal area and species density in each site, based on the best-fit nonlinear model (Eq. 2c), and including plot as a covariate. Reported are the range in the estimated slopes relating observed to predicted values for each plot, the number of slopes that were significantly positive, significantly negative, and nonsignificantly different from zero. The numbers in parentheses refer to the number of plots included in this analysis for each site.
