Eco-evolutionary factors that influence its demographic oscillations in Prochilodus costatus (Actinopterygii: Characiformes) populations evidenced through a genetic spatial-temporal evaluation. [PDF]
Evol Appl, 2023 Abstract The human activity impact on wild animal populations is indicated by eco‐evolutionary and demographic processes, along with their survival and capacity to evolve; consequently, such data can contribute toward enhancing genetic‐based conservation programs.

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

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 ...
