  1. Total PERMANOVA model including the three groups (North, Center, and South groups) and pairwise comparisons between groups. Table include degrees of freedom (DF), sum of squares (SS), mean of squares (MS), Pseudo-F ratio and p-values. P-values were calculated with 9999 permutations of the residual model [48]. * significant values
