| Abstract: | Background Tectonic, volcanic and climatic events that produce changes in hydrographic systems are the main causes of diversification
and speciation of freshwater fishes. Elucidate the evolutionary history of freshwater fishes permits to infer theories on
the biotic and geological evolution of a region, which can further be applied to understand processes of population divergence,
speciation and for conservation purposes. The freshwater ecosystems in Central Mexico are characterized by their genesis dynamism,
destruction, and compartmentalization induced by intense geologic activity and climatic changes since the early Miocene. The
endangered goodeid Zoogoneticus quitzeoensis is widely distributed across Central México, thus making it a good model for phylogeographic analyses in this area. |
