  1. N: number of individuals sampled, Nf:Nm: number of females divided by number of males, Ar: allelic richness, HO: mean observed heterozygosity, HE: mean unbiased expected heterozygosity, FIS: mean individual inbreeding coefficient. HO, HE and FIS are followed by their 95% confidence interval. HWE deviations: number of deviations from Hardy–Weinberg equilibrium out of the 18 loci tested, after false discovery rate correction. Ne: effective population size estimated by the linkage disequilibrium method, lowest frequency used 0.05, CI95%: Jack knife confidence interval, ∞: infinite value
