Supplementary Table 2. Results of Mantel permutation tests between the Sørensen and Simpson dissimilarity matrices and between the Sørensen and nestedness-resultant component matrices

Results of Mantel permutation tests (Mantel 1967; Manly 2007) between the Sørensen and Simpson dissimilarity matrices (upper table) and between the Sørensen and nestedness-resultant component matrices (lower table). All matrices were computed using the package betapart (Baselga and Orme 2012) in R v.3.0.2. (R Development Core Team, 2010). Only localities with at least 4 species, and clusters with at least 7 species and 3 clades were retained in the analyses. Abbreviations: n, number of taxa; N, number of sites; r, correlation coefficient associated to the Mantel tests; p, p-value associated to the Mantel tests calculated using 1000 permutations.
