Chromosomal differentiation between populations of Oligosarcus hepsetus (Teleostei, Characidae) from small tributaries at opposite margins of the Paraíba do Sul river (Brazil)

Cytogenetic analyses were carried out in two populations of Oligosarcus hepsetus from tributaries at opposite margins of the Paraíba do Sul river. The same diploid number was observed in both populations (2n=50), but they showed remarkable differences related to karyotype formula and distribution of...
