Fig. 2From: Multiple waves of freshwater colonization of the three-spined stickleback in the Japanese ArchipelagoMaximum likelihood phylogenetic tree of non-hybrid individuals from Japan based on 1919 concatenated SNPs. Bootstrap values (> 60%) are shown. Individuals from native freshwater populations of Gasterosteus aculeatus are highlighted in blue and those from non-native populations of G. aculeatus are highlighted in grey. Non-native population names are marked with asterisks. Blue arrowheads indicate monophyletic freshwater populations and a group of freshwater populations in vicinityBack to article page
