¹Departures of within-population inbreeding coefficients (f) from HWE were not detected; ²A population is considered to have undergone a bottleneck if its M-ratio value falls below the lower threshold of critical M-ratio (Mc = 0.625) showed on Table 4; ³No bottlenecks detected.
Populations sampled, number of alleles (A), number of private alleles (PA), allelic richness (AR), private allelic richness (PAR), expected heterozygosity (H_E), the within population inbreeding coefficient f and the M-ratio values for six nuclear loci.
