Fig. 2

Individual based assignments of nuclear genotypes by STRUCTURE and population-based PCA. a Average admixture coefficient among populations, for K = 6; circle sizes are proportional to sample sites; the red line shows the shoreline at the Last Glacial Maximum; b individual assignment with K = 6; c Individual assignments of continental green toads with K = 2, distinguishing the lineages of viridis (green) and variabilis (blue); d First two axes of the population PCA. Triangles and circles discriminate between insular and continental localities, respectively Major islands are encircled. Colors correspond to the clustering of STRUCTURE
