Molecular organization of 5S rDNA in fishes of the genus Brycon.
TLDR
5S rDNA sequencing and chromosomal localization permitted the characterization of Brycon spp. Expand
Distribution of sex chromosome mechanisms in neotropical fish and description of a ZZ/ZW system in Parodon hilarii (Parodontidae)
TLDR
A review of the sex chromosome of neotropical fish is presented and some aspects of their differentiation are discussed, with emphasis on the family Parodontidae. Expand
Population Substructuring in a Migratory Freshwater Fish Prochilodus argenteus (Characiformes, Prochilodontidae) from the São Francisco River
TLDR
FST estimates showed a significant population differentiation between the two sites, indicating the possible existence of distinct gene pools in Prochilodus argenteus, and could provide very important information for fisheries management, aquaculture and conservation of the stocks of this species. Expand
Organization of 5S rDNA in species of the fish Leporinus: two different genomic locations are characterized by distinct nontranscribed spacers.
TLDR
The nucleo- tide sequence and organization array of 5S rDNA were investigated in the genus Leporinus, a representative freshwater fish group of South American fauna and it was found that the NTS-I sequence was variable among Leporine spp. Expand
Organization of 5S rDNA in species of the fish Leporinus: two different genomic locations are characterized by distinct nontranscribed spacers.
TLDR
The nucleotide sequence and organization array of 5S rDNA were investigated in the genus Leporinus, a representative freshwater fish group of South American fauna to address understanding the organization of the5S rRNA multigene family in the fish genome. Expand
Characterization of Eight Species of Anostomidae (Cypriniformes) Fish on the Basis of the Nucleolar Organizing Region
SUMMARYThe present study shows the distribution of nucleolar organizing regions (NORs) in eight species of fresh-water fish of family Anostomidae belonging to the genera Leporinus, Leporellus andExpand
A new genus of Anostomidae (Ostariophysi: Characiformes): Diversity, phylogeny and biogeography based on cytogenetic, molecular and morphological data.
TLDR
A time-calibrated phylogenetic and biogeographical analysis of the new genus suggests that speciation in the proto-Amazon-Orinoco lineage was primarily driven by paleogeographic processes, such as the formation of the Orinoco and Tocantins basins. Expand
Evidence of lack of population substructuring in the Brazilian freshwater fish Prochilodus costatus
TLDR
Fish from the three sites had quite similar genetic diversity levels and no genetic differentiation was detected, suggesting that P. costatus might represent a single reproductive unit in the studied area, and the present study was not able to detect putative coexistent and comigrating populations along the main channel river. Expand
Genetic population structure of two migratory freshwater fish species (Brycon orthotaenia and Prochilodus argenteus) from the São Francisco River in Brazil and its significance for conservation
TLDR
The genetic structure of Brycon orthotaenia and Prochilodus argenteus, two commercially important species in the Sao Francisco River Basin (Brazil), was revisited using microsatellites to provide information for knowledge regarding geneticructure of migratory fish species. Expand
