Journal ArticleDOI
Three sympatric karyomorphs in the fish Astyanax fasciatus (Teleostei, Characidae) do not seem to hybridize in natural populations
Maressa Ferreira-Neto,Roberto Ferreira Artoni,Marcelo Ricardo Vicari,Orlando Moreira Filho,Juan Pedro M. Camacho,Mohammed Bakkali,Claudio Oliveira,Fausto Foresti +7 more
TL;DR: The findings strongly suggest the presence of three separate species easily diagnosed on the basis of differences in the diploid chromosome numbers and other chromosomal markers in characid fish Astyanax fasciatus.
Journal ArticleDOI
Comparative cytogenetics in Astyanax (Characiformes: Characidae) with focus on the cytotaxonomy of the group
Renata Cristina Claudino de Oliveira Tenório,Carla A. Vitorino,Issakar Lima Souza,Claudio Oliveira,Paulo Cesar Venere +4 more
TL;DR: The results show an interesting karyotypic diversity in Astyanax and indicate the need of a review of the group referred as A. bimaculatus and the description ofAstyanax sp.
Journal ArticleDOI
A ZZ/ZW sex chromosome system in Imparfinis mirini (Pisces, Siluriformes)
TL;DR: The karyotype, the number and position of the nucleolus organizer region (NORs) and the pattern of distribution of constitutive heterochromatin in chromosomes of males and females of Imparfinis mirini are described.
Journal ArticleDOI
Genetic variability of two populations of Pseudoplatystoma reticulatum from the Upper Paraguay River Basin
Marcia Matos de Abreu,Luiz Henrique Garcia Pereira,Vilma Barretto Vila,Fausto Foresti,Claudio Oliveira +4 more
TL;DR: The results obtained present evidence of genetic structuring in a P. reticulatum population and the division of the fishes into two groups was confirmed by microsatellite multi-locus Bayesian assignment testing.
Journal ArticleDOI
Molecular Identification of Mullet Species of the Atlantic South Caribbean and South America and the Phylogeographic Analysis of Mugil liza
TL;DR: The results indicated the existence of eight groups among the authors' Atlantic samples, and two of them are possibly new species, and it was concluded that M. liza has a wide distribution in the Atlantic coast of the South Caribbean and South America and that all specimens analyzed of this species belong to a single population.
