  1. *After excluding two outlier SNPs and three mitochondrial SNPs (see text for details). n, sample size; AR, allelic richness or number of alleles corrected for a minimum sample size of 76 diploid individuals; HE, unbiased expected heterozygosity; HWE, goodness-of-fit to Hardy-Weinberg Equilibrium expectations. §E = early migrants; L = late migrants. MBEA = mainland beach; IBEA = island beach; TRIB = tributary. Historical dates of peak spawning activity.
