Heavy Metals in Soils: An Investigation of the Contaminated Floodplains Around the Sinu River, Colombia

GeoHealth, Volume 10, Issue 3, March 2026.
Abstract Heavy metal contamination in rivers mostly originates from anthropogenic sources such as industrial activities, mining, agriculture, and urban runoff. These metals accumulate in river sediments and impact living organisms and the surrounding ecosystem. Historically, some rivers in Colombia have faced issues related to heavy metal contamination,

Conservation evidence is biased but can support decision‐making for prevalent and severe threats in tetrapods

Journal of Applied Ecology, Volume 63, Issue 3, March 2026.
Despite taxonomic and spatial biases, substantial conservation evidence is available to support decision‐making by practitioners, particularly for the most prevalent and severe threats. Given the current biodiversity crisis, it is critical that this information is more widely used and that coordination among academic and practitioner partners is ...

CORPORATE FUTURES, ENERGY TRANSITION, AND NATURAL PROSTHETICS IN COLOMBIA'S CESAR MINING CORRIDOR

Cultural Anthropology, Volume 41, Issue 1, Page 134-162, February 2026.
ABSTRACT This essay examines the socioecological transformations of mining and post‐mining landscapes in the mining corridor of the Cesar Department, northern Colombia. When an open pit mine is about to close or has recently closed, companies promote post‐mining strategies framed as ecosystem restoration and social compensation.

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

Earth'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.

Plate tectonics and the origin of the Juan Fernández Ridge: analysis of bathymetry and magnetic patterns

Latin American Journal of Aquatic Research, 2014
Juan Fernández Ridge (JFR) is a cα. 800 km long alignment of seamounts and islands which is thought to be fed by a deep mantle plume. JFR includes the Friday and Domingo seamounts in the western active edge close to the active hotspot, and the O'Higgins ...

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

Water 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 ...
