First record of megaleporinus piavussu (characiformes: anostomidae) from Argentina
(Peces Criollos, 2020-03)
Megaleporinus obtusidens and M. macrocephalus were known to be the only representatives of the genus in Argentina and the former was also the only species recorded from the Paraná river in the country. Recent collection ...
Chromosomal locations of U2 snDNA clusters in Megaleporinus, Leporinus and Schizodon (Characiformes: Anostomidae)
(2018-03-01)
The U small nuclear RNA (U snRNA) genes comprise a multigene family and are required for splicing of pre-mRNA. In this paper, we aimed to study the chromosomal location of the U2 snRNA gene in Megaleporinus, Leporinus and ...
Energy and protein ingredients for use in piapara (Megaleporinus obtusidens) diets: Nutritive value and intestinal morphometryIngredientes energéticos e proteicos para uso em dietas da piapara (Megaleporinus obtusidens): valor nutricional e morfometria intestinal
(2021-06-22)
The apparent digestibility coefficients for crude protein (ADCCP), dry matter (ADCDM), and gross energy (ADCGE) of ingredients were determined for piapara (Megaleporinus obtusidens). Test diets were formulated to contain ...
Association of epistylis spp. (ciliophora: Peritrichia) with parasitic crustaceans in farmed piava megaleporinus obtusidens (characiformes: Anostomidae)Associação de Epistylis spp. (Ciliophora: Peritrichia) com crustáceos parasitas em piava Megaleporinus obtusidens de cultivo (Characiformes: Anostomidae)
(2018-07-01)
Parasitic diseases have caused significant problems to global aquaculture production. These studies will further our knowledge of this complex problem and help implement adequate prevention measures and control strategies. ...
Satellitome landscape analysis of Megaleporinus macrocephalus (Teleostei, Anostomidae) reveals intense accumulation of satellite sequences on the heteromorphic sex chromosome
(2019-12-01)
The accumulation of repetitive DNA sequences on the sex-limited W or Y chromosomes is a well-known process that is likely triggered by the suppression of recombination between the sex chromosomes, which leads to major ...
Differentiation and Evolution of the W Chromosome in the Fish Species of Megaleporinus (Characiformes, Anostomidae)
(2018-06-08)
The W chromosome of Megaleporinus trifasciatus was isolated in order to analyze its behavior in the karyotype of this and other species of the family, including forms with differentiated and undifferentiated sex chromosomes. ...
Genomic Differences Between the Sexes in a Fish Species Seen Through Satellite DNAs
(2021-09-30)
Neotropical fishes have highly diversified karyotypic and genomic characteristics and present many diverse sex chromosome systems, with various degrees of sex chromosome differentiation. Knowledge on their sex-specific ...
