Invasive Fishes Interact With Temperature to Reshape Community Size Structure Across Climatic Zones

open access: yesGlobal Change Biology, Volume 32, Issue 4, April 2026.
Non‐native fishes are reshaping lacustrine communities across climatic zones worldwide through trophic‐ and temperature‐dependent pathways that are leading to flatter size spectrum exponents and a decline in the total biomass of the native community.

Cellular responses of Prochilodus lineatus hepatocytes after cylindrospermopsin exposure

open access: yesToxicology in Vitro, 2011
Cylindrospermopsin is a potent toxicant for eukaryotic cells produced by several cyanobacteria. Recently, primary hepatocyte cultures of Neotropical fish have been established, demonstrating to be a quite efficient in vitro model for cellular toxicology studies.

Electrified rhythms: How hydropower infrastructure transforms hydrosocial relations of riverine communities in the Lower Sogamoso River, Colombia

open access: yesPeople and Nature, Volume 8, Issue 3, Page 782-796, March 2026.
Abstract Hydropower dams regulate water flows for millions of downstream inhabitants worldwide, altering water availability. Under a changing climate, flow control is often framed technically and politically as being essential for reducing drought and flood risks. However, it can also disrupt ecological flows, impact livelihoods and erode environmental

Fine‐Scale Genomic Divergence in the Amazonian Pirarucu (Arapaima gigas) Highlights the Need for Local Management Strategies

open access: yesFreshwater Biology, Volume 71, Issue 3, March 2026.
ABSTRACT Freshwater habitats face significant human disturbances globally, impacting food security and ecosystems. Protected areas can mitigate biodiversity loss, but limited data on population connectivity hinders conservation management. This study examines pirarucu (Arapaima gigas), a heavily exploited and threatened Amazonian fish, using genomic ...

Optimizing Total Suspended Solids Mitigation in a Data‐Limited Watershed: A Network‐Based Advection–Reaction Model Applied to the Canal del Dique, Colombia

open access: yesWater Resources Research, Volume 62, Issue 2, February 2026.
Abstract Total Suspended Solids (TSS) significantly degrade water quality by reducing light penetration and oxygen availability, while facilitating the transport of toxic contaminants. Managing TSS in watersheds requires an understanding of both hydrological connectivity and pollutant dynamics; however, these efforts are significantly constrained by ...
