Summary of genetic diversity statistics in 19 populations of Sargassum horneri in Korean waters as well as the East China Sea (ECS) at seven microsatellite markers. N: sample size, N_A: mean number of alleles across loci, H_E: expected heterozygosity, H_O: observed heterozygosity, AR: allelic richness, HWE: P values for multilocus tests for Hardy-Weinberg Equilibrium.

Four populations (KF17a-1, KF17a-5, KF17b-1 and K1) with insufficient sample sizes (N < 10) were excluded from some of the genetic diversity statistics (e.g. AR, HWE). Population abbreviations as in Table 1. *P < 0.05 after a Bonferroni correction applied; NS: not significant.
