Table 1.
Within-locality genetic diversity indices for 11 Saccharina latissima localities genotyped with single nucleotide polymorphisms (SNPs) and 10 localities genotyped with genomic and ESTderived microsatellites (SSRs). N—number of genotyped samples, HO—observed heterozygosity, HE—expected heterozygosity, FIS—inbreeding coefficient (significant values (p-value < 0.05) marked with *), Ar—allelic richness (for the SNPs the alleles were rarefied down to ten alleles and for the SSRs the alleles were rarefied down to 44 alleles), and Pr Allele %—percentage of the total number of private alleles (total of 2337 private alleles for SNPs, and 37 private alleles for SSRs). SE—standard error. NA—the analyses were not performed. CAS—Castelo do Neiva, POR—Portiño de Dexo, LOC—Locmariaquer, STG—St. Guenolé, LAN—Lanildut, LEZ—Lézardrieux, FER—Fermanville, AUD—Audresselles, HEL—Helgoland, ELL—Ellenabeich, NYA—Ny-Ålesund.
