The fish genus Astyanax is widespread throughout the Neotropical region and is one of the most species-rich genera of the Characiformes. Cytogenetic studies of Astyanax have revealed marked intra-and interspecific diversity, with the identification o

The fish genus Astyanax represents a suitable model to test the role of chromosomal changes in population structure and speciation. Therefore, we performed a detailed karyotypic analysis of Astyanax aff. fasciatus from rivers in South America with in

Characiformes is the most cytogenetically studied group of freshwater Actinopterygii, but karyotypical data of several taxa remain unknown. This is the case of Nematocharax , regarded as a monotypic genus and characterized by marked sexual dimorphism

In the present work, morphometric and cytogenetic analyses were carried out in populations of the fish Astyanax fasciatus (Characidae) from Contas and Reconcavo Sul River basins (State of Bahia, Brazil), providing new data on the genetic structure of
