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.

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 ...

Fisheries in a border area of the Moxos Lowlands (Bolivia) after invasion of Arapaima gigas
Aquaculture, Fish and Fisheries, Volume 3, Issue 2, Page 196-210, April 2023., 2023 We characterized fisheries in the area of the port city of Riberalta (upper Madeira River basin) and evaluated the contribution of an invasive species (Arapaima gigas) to the landings. A. gigas represented 57.6% of the overall economic value of fish in the region.

Pimelodus maculatus Lacepede 1803
, 2018 Pimelodus maculatus. The diploid number of this species was also 56 chromosomes (24 m + 20 sm + 6 st + 6 a) (Fig. 1c). The AgNORs were located in the terminal region of the long arm of a pair of subtelocentric chromosomes 23 (Fig. 1c, box). C-banding revealed the existence of pale heterochromatin in the region of the telomeres of some chromosomes, with
