Values are weighted means of Bray–Curtis dissimilarities (low values = high overlap).

Superscripts reflect significant pairwise differences in intraspecific variation, measured as dispersion (occurrence-based permutation test, F_6,285 = 16.94, P ≤ 0.001; RRA-based permutation test F_6,285 = 12.88, P ≤ 0.001).
