Chromosomal analysis of Centromochlus heckelii (Siluriformes: Auchenipteridae), with a contribution to Centromochlus definition [PDF]

Neotropical Ichthyology, 2020
ABSTRACT Historically, there are divergences in the species allocation between Centromochlus and Tatia. This study aimed to generate the first cytogenetic data about Centromochlus and, by analyzing a population of Centromochlus heckelii from the Amazon River basin, to contribute as evidence to a historical taxonomic dilemma.

Hearing in catfishes: 200 years of research

Fish 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.

A molecular assessment of species diversity in Tympanopleura and Ageneiosus catfishes (Auchenipteridae: Siluriformes) [PDF]

Journal of Fish Biology, 2019
AbstractIn order to test the congruence of genetic data to the morphologically defined Neotropical catfish genera Tympanopleura and Ageneiosus and explore species diversity, we generated 17 DNA barcodes from five of six species of Tympanopleura and 12 of 13 species of Ageneiosus.

Application of a deep learning image classifier for identification of Amazonian fishes

Ecology and Evolution, Volume 13, Issue 5, May 2023., 2023
To address the growing prevalence of large ecological datasets combined with a need for rapid species identification tools, we describe a novel application of a computer vision model, which is built to rapidly identify Amazonian fishes from captured image data.

New phylogenetic insights into the African catfish families Mochokidae and Austroglanididae

Journal of Fish Biology, Volume 100, Issue 5, Page 1171-1186, May 2022., 2022
Abstract Several hundred catfish species (order: Siluriformes) belonging to 11 families inhabit Africa, of which at least six families are endemic to the continent. Although four of those families are well‐known to belong to the ‘Big‐Africa clade’, no previous study has addressed the phylogenetic placement of the endemic African catfish family ...

Conservation threats and future prospects for the freshwater fishes of Ecuador: A hotspot of Neotropical fish diversity

Journal of Fish Biology, Volume 99, Issue 4, Page 1158-1189, October 2021., 2021
ABSTRACT Freshwater fish communities in Ecuador exhibit some of the highest levels of diversity and endemism in the Neotropics. Unfortunately, aquatic ecosystems in the country are under serious threat and conditions are deteriorating. In 2018–19, the government of Ecuador sponsored a series of workshops to examine the conservation status of Ecuador's ...

Auchenipteridae Bleeker 1862

, 2009
Auchenipteridae There are six auchenipterid species inhabiting the upper rio Paraná, distributed in the genera Ageneiosus, Auchenipterus, and Trachelyopterus. Two Ageneiosus species colonized the upper Paraná after the Itaipu impoundment: A. inermis (formerly called A. brevifilis) and A. ucayalensis.
