  1. Three tests were used; MRPP, multi-response permutation procedures; Adonis, permutational multivariate analysis of variance using distance matrices; and ANOSIM, analysis of similarity. Results are based on distance matrices calculated with Bray-Curtis index, but Sørenson was also used and generated similar outcomes
