The Rediscovery of a Long Described Species Reveals Additional Complexity in Speciation Patterns of Poeciliid Fishes in Sulfide Springs
Figure 3
Body shape variation of Poecilia species in the lateral projection.
Depicted are mean principal component scores along the first two principal component axes for each site for P. thermalis (yellow circles), P. sulphuraria (yellow triangles), as well as sulfidic and non-sulfidic populations of P. mexicana across the 23 study sites in southern Mexico. The thin-plate spline transformation grids represent shape variation along each principal component axis.
