Structure of Fundulus populations. (A) Population structure as assessed by STRUCTURE. Bar plot was generated by DISTRUCT and depicts the classifications of the populations with the highest probability under the model. K indicates the number of clusters that maximized the probability of the model. Each individual is shown as a vertical bar. (B) Principal components PC1, PC2 and PC3 from all SNPs (as calculated in JMP Genomics 3.2) among all individuals. Species are separated from each other as well as northern and southern F. heteroclitus populations. Colors represent different species. (C) Principal components PC1, PC2, and PC3 from all SNPs among F. heteroclitus individuals. Colors represent different populations.
