Figure 2From: Multilocus dataset reveals demographic histories of two peat mosses in EuropeGeographic distribution of S. squarrosum haplotypes and the corresponding maximum parsimony networks. In each haplotype network, letters in circles represent haplotypes found. Missing haplotypes are marked with black dots and lines connecting haplotypes denote one mutational change. Well-differentiated clades are shown within red, green and blue ellipses. Letters on the map have the colour of the corresponding genetic clade.Back to article page
