Given are the sample sizes (n) of the years the Høvblege population could be studied and the total number of alleles (k), mean allelic richness (k') based on 3 independent diploid individuals, expected heterozygosity (He), inbreeding coefficient (F_IS) and the ratio between allele number and allele range (M-ratio) calculated according to Garza and Williamson (2001). Asterisk indicates significance level: * P < 0.05.
