  1. Data were transformed into Bray–Curtis dissimilarities for analysis. P values for permutational MANOVA and permutation tests for homogeneity of multivariate dispersions are shown. Significant tests (p ≤ 0.05) are indicated in bold.
  2. df degrees of freedom, SS sum of squares, R2 coefficient of determination (proportional explained variation), p p value.
