Genetic structure and its spatial distribution of P. latipinna genetic clusters. (a) Membership-coefficient plot with STRUCTURE results with optimal k = 6 inferred by Bayesian analysis. Each bar represents an individual genotype ordered by sampling location. Distinct colors indicate the relative cluster membership probability. (b) Sampling area, palaeodrainage reconstruction, and geographical distribution of genetic clusters found in Sailfin mollies. Pie charts colors represent the average membership proportion for all genetic clusters within a sampling site. Colors in the continent (and palaeodrainages) represent river basins reconstructed via palaeodrainage reconstruction (see Methods below). Dark solid line represents current coastline (0 m above sea level); dashed white line denotes sea level at the last glacial maximum (125 m below current sea level.) Orange cluster: west of Alabama; Red cluster: northwest Florida; Green cluster: Florida west coast; Light-blue cluster: Florida east coast; Dark-blue cluster: Florida inland; Yellow cluster: South Carolina
