Evolutionary history of the fish genus Astyanax Baird & Girard (1854) (Actinopterygii, Characidae) in Mesoamerica reveals multiple morphological homoplasies

BMC Evolutionary Biology, 2008
Background Mesoamerica is one of the world's most complex biogeographical regions, mostly due to its complex geological history. This complexity has led to interesting biogeographical processes that have resulted in the current diversity and distribution

Hybridization, Maternal Inheritance, and Evolutionary Time of Divergence of Endangered Species of Hypancistrus (Siluriformes: Loricariidae) in the Xingu River

Ecology and Evolution, Volume 16, Issue 5, May 2026.
We uncover recent hybridization dynamics among three endemic Hypancistrus species from the Xingu River, including the critically endangered H. zebra. Mitogenomic analyses reveal unidirectional maternal inheritance and recent evolutionary radiation (< 0.5 Ma), explaining their retained reproductive compatibility.
