Findings From the Pearl River Basin: Dissolved Oxygen Dominates Functional Trait Filtering and Diversity Patterns in Urban Rivers [PDF]
Ecology and Evolution, Volume 16, Issue 4, April 2026.Urbanization reshapes fish communities via environmental filtering. Surveying 44 sites across an urban (Huadi) and a relatively natural (Zengjiang) river in the Pearl River Basin (2024), we linked environmental variables to fish functional traits using RLQ and SEM, finding that dissolved oxygen is the dominant filter in urban reaches—selecting low ...

Genomic Insights Into Carnivorous Fish in the Characiformes [PDF]
Ecology and Evolution, Volume 16, Issue 4, April 2026.This study employed comparative genomic approaches using 12 high‐quality Characiformes genomes (covering nine subfamilies) with zebrafish as an outgroup to explore the molecular mechanisms underlying the carnivorous adaptation of Characiformes. Expanded gene families, positively selected genes, and rapidly evolving genes in carnivorous species were ...

Draft genome assembly for the colombian freshwater bocachico fish, Prochilodus magdalenae [PDF]
Frontiers in Genetics, 2023 We report the first draft genome assembly for Prochilodus magdalenae, the leading representative species of the Prochilodontidae family in Colombia. This 1.2-Gb assembly, with a GC content of 42.0% and a repetitive content of around 31.0%, is in the ...

Hybridization, Maternal Inheritance, and Evolutionary Time of Divergence of Endangered Species of Hypancistrus (Siluriformes: Loricariidae) in the Xingu River [PDF]
Ecology and Evolution, Volume 16, Issue 5, May 2026.We uncover recent hybridization dynamics among three endemic Hypancistrus species from the Xingu River, including the critically endangered H. zebra. Mitogenomic analyses reveal unidirectional maternal inheritance and recent evolutionary radiation (< 0.5 Ma), explaining their retained reproductive compatibility.

Spatial and temporal population genetic analysis of Semaprochilodus insignis (Prochilodontidae), an overexploited fish from the Amazon basin [PDF]
PeerJ, 2023 Background Semaprochilodus insignis is a migratory fish of commercial and subsistence importance to communities in the Amazon. Despite the high intensity of exploitation, recent studies have not been carried out to assess the genetic status of its stocks.
