Abstract excerpt
The Neotropical catfish family Callichthyidae is characterized by wide karyotype variation, although reports are restricted to a few species/populations. This work provides new chromosomal information in two populations of armoured catfish (Callichthys callichthys) within the Atlantic forest boundaries in northeastern Brazil. Both populations of C. callichthys presented 2n=54 (16 metacentric, 24 submetacentric, 6...
