Cephalic Musculature of the Pacman Catfish Lophiosilurus alexandri Steindachner, 1876 (Siluriformes, Pseudopimelodidae). [PDF]

open access: yesJ Morphol
The head of the Pacman catfish (Lophiosilurus alexandri [L. alexandri]) is strongly depressed, broad, and with a large mouth, roughly resembling those of Lophius piscatorius and Chaca bankanensis. Also, they are bottom dwellers and have ambush behavior for fish predation.

Establishing new grid-size-dependent attributes to rank areas of endemism for conservation priorities. [PDF]

open access: yesCladistics
Abstract Delineating Areas of Endemism (AEs) is crucial for identifying priority areas for biodiversity conservation in a spatial planning framework. Endemicity Analysis in the NDM/VNDM software is one of the primary methodologies for its delineation.

Pimelodus heraldoi Azpelicueta, 2001, a junior synonym of Pimelodus microstoma Steindachner, 1877 (Siluriformes: Pimelodidae) [PDF]

open access: yesNeotropical Ichthyology, 2010
The examination of the holotype and 61 of the 64 paratypes of Pimelodus heraldoi, syntypes of P. microstoma and additional specimens from the upper rio Paraná showed that the former species is a junior synonym of the latter.

Hydrological Connectivity Enhances Fish Biodiversity in Amazonian Mining Ponds: Insights From eDNA and Traditional Sampling. [PDF]

open access: yesMol Ecol
ABSTRACT Artisanal and small‐scale gold mining (ASGM) expansion in the Madre de Dios region of the Peruvian Amazon has transformed primary forests into a novel wetland complex of thousands of abandoned mining ponds. Despite their ecological relevance, post‐mining recovery of these systems remains understudied, particularly regarding fish biodiversity ...

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

open access: yesEnvironmental 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

open access: yesEcology 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 ...

Hearing in catfishes: 200 years of research

open access: yesFish and Fisheries, Volume 24, Issue 4, Page 618-634, July 2023., 2023
Abstract Ernst Weber stated in 1819, based on dissections, that the swimbladder in the European wels (Silurus glanis, Siluridae) and related cyprinids serves as an eardrum and that the ossicles connecting it to the inner ear function as hearing ossicles similar to mammals. In the early 20th century, K.
