DNA metabarcoding of mock communities highlights potential biases when assessing Neotropical fish diversity

Environmental DNA, Volume 5, Issue 6, Page 1351-1361, November 2023., 2023
The performance of a taxonomy‐free approach using ASV/MOTUs was not as precise as assigning DNA reads to species using a curated 12S library that includes approximately 100 fish species since more than one ASV/MOTU was observed for the same specimen.

DNA metabarcoding assessment of Neotropical ichthyoplankton communities is marker‐dependent

Ecology and Evolution, Volume 13, Issue 10, October 2023., 2023
DNA metabarcoding has been applied as a rapid, cost‐effective, and accurate taxonomy tool, allowing the identification of multiple individuals simultaneously. The combined use of the three markers increased the genera detection rates by 25%–87.5%, allowing an increased taxonomic coverage and robust taxonomic identification of complex Neotropical ...

Karyotypic variation in the long-whiskered catfish Pimelodus blochii Valenciennes, 1840 (Siluriformes, Pimelodidae) from the lower Tapajós, Amazonas and Trombetas Rivers

Comparative Cytogenetics, 2018
The genus Pimelodus LaCépède, 1803 comprises 35 formally recognized species distributed along the major neotropical river basins. Despite conservatism in diploid number with 2n=56, an intense variation of chromosomal morphology (karyotypic formula) has ...

A new species of the genus Pimelodus La Cépède, 1803 from the rio Iguaçu basin and a reappraisal of Pimelodus ortmanni Haseman, 1911 from the rio Paraná system, Brazil (Ostariophysi: Siluriformes: Pimelodidae)

Neotropical Ichthyology
A new species, Pimelodus britskii, is described from the rio Iguaçu in the rio Paraná drainage, on the border of Paraná and Santa Catarina states, Brazil. Specimens of this species were wrongly included in the type series of Pimelodus ortmanni. Pimelodus
