Vegetation and channel adjustment trajectories in cold regions: The effects of ice disturbances in two Gaspesian rivers

Earth Surface Processes and Landforms, Volume 50, Issue 5, April 2025.
This study explores the role of ice jam regimes on the biogeomorphological dynamics of two cold‐climate rivers. The analysis of vegetation and channel planform adjustments on a 60‐year timescale showed that the ice jam regime had notable impacts on vegetation successional dynamics, which further modulate geomorphological changes.

Linking Surface Processes, Solute Generation, and CO2 Budgets Across Lithological and Land Cover Gradients in Rocky Mountain Watersheds

Water Resources Research, Volume 61, Issue 4, April 2025.
Abstract Chemical weathering in mountain critical zones controls river chemistry and regulates long‐term climate. Mountain landscapes contain diverse landforms created by geomorphic processes, including landslides, glacial moraines, and rock glaciers. These landforms generate unique flowpaths and water‐rock interactions that modify water chemistry as ...

Climate Adaptation for a Natural Atoll Island in the Maldives ‐ Predicting the Long‐Term Morphological Response of Coral Islands to Sea Level Rise and the Effect of Hazard Mitigation Strategies

Earth's Future, Volume 13, Issue 4, April 2025.
Abstract Coral atoll islands, common in (sub)tropical oceans, consist of low‐lying accumulations of carbonate sediment produced by fringing coral reef systems and are of great socio‐economic and ecological importance. Previous studies have predicted that many atoll islands will become uninhabitable before the end of this century due to sea level rise ...

Deep learning selection of analogues for Mars landing sites in the Qaidam Basin, Qinghai-Tibet Plateau [PDF]

arXiv
Remote sensing observations and Mars rover missions have recorded the presence of beaches, salt lakes, and wind erosion landforms in Martian sediments. All these observations indicate that Mars was hydrated in its early history. There used to be oceans on Mars, but they have now dried up.

Construction of Ultraslow‐Spreading Oceanic Crust: New Insights on Volcanic Processes and Deposits From High‐Resolution Mapping at the Mohns Ridge

Geochemistry, Geophysics, Geosystems, Volume 26, Issue 4, April 2025.
Abstract The volcanic activity at ultraslow‐spreading ridges is less understood compared with that at faster‐spreading ridges. Studies of year‐to‐year changes along the faster‐spreading ridges have provided important information regarding the size and frequency of eruptions.

Use of Water Quality Index and Pesticides‐Related Human Health Risk Assessment for Evaluating the Surface Water Sustainability Status of the Kakia‐Esamburmbur Agricultural Watershed, Narok County, Kenya

GeoHealth, Volume 9, Issue 4, April 2025.
Abstract The increase in water contaminants threatens ecosystems and human health, underscoring the need for effective water quality (WQ) control. This study assessed the Kakia‐Esamburmbur catchment's water sustainability status for drinking purposes by analyzing water samples from the catchment.

The Rise and Fall of Marpha Lake, a Late Quaternary Dammed Lake in the Himalayan Rain‐Shadow With Implications to Landscape Evolution and Sediment Dynamics

Journal of Geophysical Research: Earth Surface, Volume 130, Issue 4, April 2025.
Abstract Understanding landscape evolution history and sedimentary dynamics in high mountainous regions is tampered by rapid erosion of the sedimentary archives. Naturally dammed lakes provide unique snapshots of these processes and enable evaluating these processes under climatic conditions different from the present.

Urban planning for wildlife connectivity: A multispecies assessment of urban sprawl and SLOSS renaturalization strategies

Journal of Applied Ecology, Volume 62, Issue 4, Page 1007-1023, April 2025.
Notably, smaller but widely distributed natural areas can serve as a practical and effective management strategy for balancing the trade‐offs among economic costs, urban expansion and habitat conservation. To effectively support biodiversity conservation goals, such as the 30 × 30 target, these smaller natural areas should ideally be connected to ...
