  1. Genetic diversity and allelic richness observed and estimated from rarefaction algorithm calculated over the nine loci for the ten study populations and their temporal samples (codes are given in Table 1), as well as level of relatedness rxy [63], estimated based on mean (Mrxy) and variance (Vrxy) of the distribution of pairwise relatedness index, calculated for each temporal samples from each location and across temporal samples for each location (see main text for additional details)
  2. A = number of alleles observed per population; A r = allelic richness per population based on rarefaction algorithm; He = non-biased expected heterozygosity; Hobs = observed heterozygosity (with standard deviations = SD); the FIS = fixation index values with their significances after sequential Bonferroni correction; Test significance: *P < 0.05, ** P < 0.01, *** P < 0.001.
