Forensic identification of the guitarfish species Rhinobatos horkelli, R-percellens and Zapteryx brevirostris using multiplex-PCR
(Molecular Ecology Resources, 2010-01-01) [Resumo]
Rhinobatos percellens, Rhinobatos horkelli and Zapteryx brevirostris, known as guitarfish, are commonly found inshore and caught by trawl nets. Recently, these species have been suffering sharp population declines. One of ...

Molecular identification of hybrids between Neotropical catfish species Pseudoplatystoma corruscans and Pseudoplatystoma reticulatum
(Aquaculture Research, 2011-11-01) [Artigo]
Cytogenetic analysis of B chromosomes in one population of the fish Moenkhausia sanctaefilomenae (Steindachner, 1907) (Teleostei, Characiformes)
(Comparative Cytogenetics, 2012-01-01) [Artigo]
The aim of this study was to characterize cytogenetically one population of the fish Moenkhausia sanctaefilomenae (Steindachner, 1907), with emphasis on the analysis of B chromosomes. The nucleolar activity in the B ...
Genetic markers for the identification of hybrids among catfish species of the family Pimelodidae
(Journal of Applied Ichthyology, 2013-06-01) [Artigo]
Fish hybrids provide genetically manipulated products of excellent value for the commercial aquaculture industry. However, if handled or marketed incorrectly, they can cause great financial loss to producers as well as ...
Delimiting the Origin of a B Chromosome by FISH Mapping, Chromosome Painting and DNA Sequence Analysis in Astyanax paranae (Teleostei, Characiformes)
(PLOS ONE, 2014-04-15) [Artigo]
Supernumerary (B) chromosomes have been shown to contain a wide variety of repetitive sequences. For this reason, fluorescent in situ hybridisation (FISH) is a useful tool for ascertaining the origin of these genomic ...
First cytogenetic characterization of the giant Amazonian catfish Brachyplatystoma filamentosum (Siluriformes, Pimelodidae)
(Caryologia, 2014-06-01) [Artigo]
In contrast to the enormous variability of Neotropical fish species, genetic information about many groups is not yet available. Chromosomal studies have greatly contributed to the characterization of several species, ...
B-chromosome frequency stability in Prochilodus lineatus (Characiformes, Prochilodontidae)
(Genetica, 2010-03-01) [Artigo]
The genus Prochilodus includes individuals ranging in size from medium to large, being highly relevant for commercial and subsistence fishing. Prochilodus species have a diploid number of 2n = 54 chromosomes and up to seven ...
B chromosomes in the species Prochilodus argenteus (Characiformes, Prochilodontidae): morphologicalidentity and dispersion
(Comparative Cytogenetics, 2015-01-01) [Artigo]
B chromosomes have attracted the attention of Neotropical fish cytogeneticists in recent years, both for their remarkable occurrence in this group and also because of the interest in studies of the genetic structure and ...
