BACKGROUND Cichlid fishes have been the subject of increasing scientific interest because of their rapid adaptive radiation which has led to an extensive ecological diversity and their enormous importance to tropical and subtropical aquaculture. To increase our understanding of chromosome evolution among cichlid species, karyotypes of one Asian, 22 African,(More)
Among multigene families, ribosomal RNA (rRNA) genes are the most frequently studied and have been explored as cytogenetic markers to study the evolutionary history of karyotypes among animals and plants. In this report, we applied cytogenetic and genomic methods to investigate the organization of rRNA genes among cichlid fishes. Cichlids are a group of(More)
Hypostomus is a species-rich genus of fish with unclear systematics and phylogenetic relationships. Ten species of Hypostomus (H. albopunctatus, H. ancistroides, H. cochliodon, H. commersoni, H. faveolus, H. hermanni, H. aff. paulinus, H. regani, H. strigaticeps and H. topavae) were cytogenetically analyzed through Giemsa staining and silver nitrate(More)
Correction After the publication of our work [1], we detected that one of the species analyzed in the study, Astatotilapia latifasciata (Figure 1), was erroneously identified as Haplochromis obliquidens. This species was described as Haplochromis latifasciatus [2] and later ascribed to the genus Astatotilapia [3]. Our mistake comes from the fact that this(More)
