Hybrid Glacio‐Hydrological Modeling Reveals Contrasting Runoff Changes in Western Patagonia Over the 21st Century

open access: yesEarth's Future, Volume 13, Issue 11, November 2025.
Abstract Climate change poses a serious risk for the freshwater ecosystem of Western Patagonia and threatens glacial and non‐glacial water resources. Here, we model the historical glacio‐hydrology of 2,236 catchments across the Western Patagonia, and project climate change impacts through the 21st century.

Assessing Structural Geological Controls on Groundwater Processes in Mountain Settings: Insights From Three‐Dimensional Numerical Modeling

open access: yesWater Resources Research, Volume 61, Issue 8, August 2025.
Abstract Mountains play a critical role in the hydrological cycle by transferring heavy precipitation to lowland aquifers. However, their complexity and remoteness limit our understanding of groundwater flow, particularly the influence of faults. To fill the gap, semi‐idealized 3D numerical models calibrated using the mountain river network and the ...

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

open access: yesMolecular Ecology, Volume 34, Issue 11, June 2025.
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 ...
