Illegal Gold Mining in the Brazilian Amazon: Environmental Degradation in Yanomami Indigenous Lands, and Regulatory Failures

open access: yesSustainable Development, Volume 34, Issue 7, Page 9232-9246, November 2026.
ABSTRACT Illegal gold mining has emerged as a major sustainability threat in the Amazon, eroding Indigenous rights, forest integrity, and climate mitigation efforts. This study examines how international market incentives relate to the expansion of illegal mining and associated deforestation within the Yanomami Indigenous Territory (YIT) from 2008 to ...

The Amazon River‐Breeze Circulation Limits Detection of Aerosol‐Cloud Interactions in Warm Clouds

open access: yesAGU Advances
Increased aerosol concentrations can brighten low‐level clouds and extend their lifetimes, but aerosol–cloud interactions (ACI) remain highly uncertain and difficult to quantify. We show that part of this uncertainty is caused by topographical influences

Oxidative Stress Biomarkers in the Shrimp Macrobrachium amazonicum (Heller, 1862): Assessment in an Environmental Preservation Area in the Brazilian Amazon

open access: yesEnvironmental Toxicology, Volume 41, Issue 11, Page 1289-1298, November 2026.
ABSTRACT Anthropogenic activities generate a significant amount of pollutants that are released into the environment, causing physiological and ecological disturbances. Among the xenobiotics present in aquatic ecosystems, numerous chemical and organic compounds have oxidative potential or are metabolized through oxidative processes, which may amplify ...

An Unstructured Voronoi Mesh Framework for Large‐Scale Hydrologic and Land Surface Models

open access: yesJournal of Advances in Modeling Earth Systems, Volume 18, Issue 11, November 2026.
Abstract Accurate representation of river networks and land surface heterogeneity is crucial for improving the performance of continental‐to‐global hydrologic and land surface models. Traditional approaches rely on either coarse‐resolution grids, which may oversimplify complex terrain and limit the accurate representation of key processes, or ...

Hydraulic Control of Fish Distribution at Large River Confluences: Evidence for Cross‐Sectional Flow Organization

open access: yesWater Resources Research, Volume 62, Issue 11, November 2026.
Abstract Confluences are among the most hydrodynamically complex environments within fluvial networks and are widely recognized as ecological hotspots. Effective management of fish assemblages in such systems requires a mechanistic understanding of hydrodynamic‐ecological coupling.
