Figure 2.

Distribution of Sargassum muticum multi‐locus genotypes (MLGs) obtained with RAD‐seq loci in the introduction ranges. (a) Minimum spanning network on multi‐locus genotypes (MLGs) detected in the introduced ranges, based on the number of pairwise allelic differences between MLGs, with gray shading of branch inversely proportional to the distance between MLGs, and (b) population level distributions of the 14 MLGs found in the southern NE Pacific and NE Atlantic Group 1 (i.e., NE Atlantic excluding populations no.51 (Thau) & 54 (Porto)). Population private haplotypes are colored in black
