Figure 2
Overview of the study area and sampling localities of three Poecilia species in southern Mexico.
Sampling of P. thermalis, Poecilia mexicana mexicana, and P. sulphuraria in southern Mexico. The colors represent sulfidic (yellow) and non-sulfidic (blue) sites and the numbers represent localities as described in Table 2 of the main manuscript. For orientation purposes, we included black lines representing major roads and gray areas representing major towns in the region.
