Cytogenetic analysis of three sea catfish species (Teleostei, Siluriformes, Ariidae) with the first report of Ag-NOR in this fish family
(Sociedade Brasileira de Genética, 2010-01-01)
Despite their ecological and economical importance, fishes of the family Ariidae are still genetically and cytogenetically poorly studied. Among the 133 known species of ariids, only eight have been karyotyped. Cytogenetic ...

Extensive spreading of interstitial telomeric sites on the chromosomes of Characidium (Teleostei, Characiformes)
(Springer, 2015-06-01)
Characidium comprises several species of small freshwater fish that display conserved diploid chromosome numbers and karyotypic formulae. In this study, a comparative cytogenetic analysis using telomeric DNA probes was ...

The Antarctic and South American species of Deschampsia: phylogenetic relationships and cytogenetic differentiation
(Cambridge University Press, 2021-03)
Deschampsia P. Beauv. is a cosmopolitan grass genus, which grows in cold and temperate regions, including about 15 species growing in South America and Antarctica. The species delimitation is difficult due to the high ...
Cytogenetic characterization of Hoplias malabaricus (Bloch, 1794) from the Ctalamochita River (Córdoba, Argentina) : first evidence for southernmost populations of this species complex and comments on its biogeography
(Pensoft, 2017-01-09)
Hoplias malabaricus (Bloch, 1794), a predatory freshwater fish with a wide distribution throughout South America, represents a species complex with seven well characterized karyomorphs at the cytogenetic level. Although ...
