Figure 2 in Phylogeographic patterns in attached and free-living marine macroalga Fucus vesiculosus (Fucaceae, Phaeophyceae) in the Baltic Sea

Figure 2: Haplotype network analysis of Fucus vesiculosus using (A) concatenated-barcode mtDNA intergenic spacer (IGS) and 23S, and (B) mtDNA polymorphic region-intergenic spacer (pr-IGS). Circle size is proportional to the haplotype frequency. A branch represents a genetic distance and hash marks represent a single mutation. Branches drawn in broken grey lines represent genetic distances between non-linked haplotypes [not shown in (B)]. All undrawn branches between non-linked haplotypes within B equal <2 mutations. Segment colouration indicates the geographic origin of each haplotype whilst ellipses represent the coverage of each geographic region within the network.
