General increase in assemblage dissimilarity by the inclusion of exotic species into indigenous assemblages.

β indicates the averaged values of the species replacement index calculated per each considered habitat category and for the whole epigean arthropod assemblages (All), and indigenous species alone. Averaged Wilcoxon Z values for the 10 rarefied matrices and numbers of cases (Nc) in which the similarity values of the whole assemblages and the indigenous species alone are statistically different (P < 0.05, SD is indicated for the β and Z values) are indicated. All cases of significant differences indicate that the inclusion of exotic species into the indigenous assemblages (All) increased the dissimilarity of the whole assemblages, with the exception of four cases in native forests indicating an increase in assemblage similarity or biotic homogenisation (see Table H in S3 File, for the Z values of the ten rarefied matrices).
