Biogeography of curimatid fishes reveals multiple lowland-upland river transitions and differential diversification in the Neotropics (Teleostei, Curimatidae). [PDF]

Ecol Evol, 2021
The time‐calibrated molecular phylogeny and geographic range evolution of the Neotropical family Curimatidae show a Late Cretaceous origin in lowland basins of South America with subsequent colonization to upland basins at multiple times during the Cenozoic.

Importance and spatial patterns of invisible fisheries in Amazonian clear-water rivers as revealed by fisher knowledge and collaboration. [PDF]

Conserv Biol
The graphical abstract highlights the research collaboration with fishers through interviews to record fishers' knowledge and participatory monitoring, to provide data on small‐scale fisheries in three clear water rivers (Trombetas, Tapajos and Tocantins).

Deciphering the complex life cycle and partial migration of an ecological engineer and critical Neotropical fishery species, Prochilodus costatus. [PDF]

J Fish Biol
Abstract Understanding complex migration patterns, including drivers of partial migration and habitat use, is challenging but essential for conservation, as it determines a species' adaptative capacity in the face of environmental change and anthropogenic threats.

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

Mol 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 ...

Application of a deep learning image classifier for identification of Amazonian fishes. [PDF]

Ecol Evol, 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.

Atresia of ovarian follicles in fishes, and implications and uses in aquaculture and fisheries. [PDF]

J Fish Dis, 2021
Abstract Atresia of ovarian follicles, that is the degenerative process of germ cells and their associated somatic cells, is a complex process involving apoptosis, autophagy and heterophagy. Follicular atresia is a normal component of fish oogenesis and it is observed throughout the ovarian cycle, although it is more frequent in regressing ovaries ...

Ontogeny of the Skeleton of Leporinus oliveirai (Characiformes, Anotomidae). [PDF]

J Morphol
In this study, we provide the first complete description of the skeleton ontogeny of an anostomid. The developmental sequence of 141 bony elements is described and illustrated. The main discoveries are numerous conical teeth on the premaxilla and dentary that are replaced with three or four large incisiform multicuspid teeth, that become unicuspid in ...

Eugenol as an efficient anesthetic for neotropical fish Prochilodus nigricans (Teleostei, Prochilodontidae) [PDF]

Arquivo Brasileiro de Medicina Veterinária e Zootecnia, 2020
The use of anesthetics in fish farming is essential to reduce stress during management. The present study proposes to evaluate the effect of eugenol as an anesthetic for the management of curimatã (Prochilodus nigricans).
