  1. The mean number of genotyped individuals per locus (Mean_N), allelic richness (Ar), expected heterozygosity (He), inbreeding coefficient FIS (with the R package DiveRsity, populations with evidence for inbreeding are indicated in bold) and the estimated effective population size (Ne) of the sampled locations. Ne is estimated in the program Colony2 while using the Random Mating model (RM) together with a 95% confidence interval (95%CI, L  lower limit, U  upper limit)
