The Rediscovery of a Long Described Species Reveals Additional Complexity in Speciation Patterns of Poeciliid Fishes in Sulfide Springs
Figure 4
Convergent changes in body shape of Poecilia species from sulfidic and non-sulfidic habitats in the lateral projection.
Depicted are the mean divergence scores (± SEM; derived from the H2S term in the MANCOVA) for each site for the three formal species (P. thermalis, P. sulphuraria, and P. mexicana) across the 23 sites in southern Mexico from sulfidic (yellow) and non-sulfidic (blue) populations including. The numbers correspond to sites as described in Table 2.
