Sampling sites and bootstrapped unrooted NJ tree for stickleback from 73 freshwater lake populations and 4 marine ones from four countries on two continents, based on 11,266 genetic markers for 1,380 individuals. All nodes shown have bootstrap support of at least 80 (other nodes were collapsed). Freshwater branches are coloured by the radiation to which they belong. Marine branches are black with the tips coloured according to radiation. Tips represent individual fish, which were generally tightly clustered by population (small labels). Stars represent lakes sampled.
