The Rediscovery of a Long Described Species Reveals Additional Complexity in Speciation Patterns of Poeciliid Fishes in Sulfide Springs
Figure 9
Genetic structure among populations based on microsatellites analysis in N = 272 individuals from 10 populations.
The top panel is a bar plot showing the assignment scores of individuals by STRUCTURE with K = 2 with yellow representing P. thermalis and P. sulphuraria as a cluster from the Puyacatengo and Pichucalco sulfidic drainages and blue representing P. m. mexicana from non-sulfidic sites in the same drainage. The bottom panel is a bar plot showing the assignment scores clustering at K = 7, the second most likely number of distinct groups.
