nuc = number of nucleotides in analysis block; n = sample size; S = number of segregating sites; Nh = number of unique haplotypes; h + SD = Haplotype diversity and standard deviation (Nei 1987, equations 8.4 and 8.12 but replacing 2n by n); π = nucleotide diversity (Nei 1987, eq. 10.5); K = nucleotide divergence (Nei 1987, eq. 10.20), θ = pop mutation rate /site/generation (Nei 1987, equation 10.3); TajimaD = gene neutrality test (Table 2 in Tajima 1989)

* significant p < 0.05;

NRB = number of non-recombining blocks (Hudson and Kaplan 1985)

Species: Sa–S. auriculatus, Sc–S. caurinus, Sm–S. maliger. Populations (pop): Co–coast, and SS–Salish Sea
