Table 1 General linear model analysis for a mixed model nested ANOVA-type design, testing for the effects of forest type (Np mixed forests dominated by Nothofagus pumilio, M mixed forests with similar proportion of N. pumilio and N. betuloides, Nb mixed forests dominated by Nothofagus betuloides) and sites (COA coast, MOU mountain) as fixed factors, and replica as random factor, on the forest structure of the study areas in Tierra del Fuego. BA basal area, TD tree density, DBH diameter at breast height, DH dominant height, L litterfall. F (p) Fisher statistic with probability in parentheses. Different letters show differences by Tukey test at p < 0.05
