Genetic characterization of the Neotropical catfish Pimelodus maculatus (Pimelodidae, Siluriformes) in the Upper Uruguay River [PDF]
Genetics and Molecular Biology, 2012 Freshwater fish present unique challenges when one attempts to understand the factors that determine the structure of their populations. Habitat fragmentation is a leading cause of population decline that threatens ecosystems worldwide. In this study, we

DNA metabarcoding assessment of Neotropical ichthyoplankton communities is marker-dependent. [PDF]
Ecol Evol, 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. [PDF]
Fish Fish (Oxf), 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.

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

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

Effect of a fat-free diet and of different dietary fatty acids (palmitate, oleate, and linoleate) on the fatty acid composition of fresh-water fish lipids [PDF]
Journal of Lipid Research, 1963 When fresh-water fish Pimelodus maculatus were fed a fat-deficient diet, the concentration of linoleic and arachidonic acids in glycerides and phospholipids decreased, and the concentration of palmitic, palmitoleic, oleic, and eicosatrienoic acids ...
