Total number of sampled colonies (N), number of NF-types (NNF), average number of alleles per locus (A), expected (HE) and observed (HO) heterozygotisy. Bold FIS-values indicate a significant departure from Hardy-Weinberg equilibrium (p < 0.01). The four groups of populations included in the AMOVA are MMP 1–4, PEM 1–4, MAF 1–4 and MTW 1–4.
