River Sand and Gravel Mining: Global Drivers, Impacts, and Pathways for Sustainable Management

Reviews of Geophysics, Volume 64, Issue 3, September 2026.
Abstract River sand and gravel are mined worldwide at volumes that now rival their natural replenishment, yet quantitative knowledge of this mining activity and its consequences lags far behind many other global environmental pressures. We synthesize 411 peer‐reviewed studies published since 1974 within a new Driver‐to‐Management Pathway for ...

High-resolution models better simulate historical snowpack declines in the Upper Colorado River Basin

Environmental Research Letters
The Colorado River supplies water to 40 million people, 4.5 million acres of irrigated land, seven US states, over two dozen federally recognized and sovereign tribes and Mexico. River discharge is strongly controlled by snowpack accumulation and melt in

Information Supply Chain Gaps for Hard‐to‐Reach Communities: A Solution‐Oriented Framework From Weather Service Insights

Community Science, Volume 5, Issue 3, September 2026.
Abstract Despite advancements in forecasting and warning technologies, some communities still face barriers to accessing essential weather and climate information. These gaps disproportionately affect individuals with limited digital access, unstable housing, or limited English proficiency, leading to uneven impacts during high‐impact weather events ...

The Role of Lightning in Atmospheric Chemistry

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 16, 28 August 2026.
Abstract Lightning has important effects on atmospheric constituents in primarily the middle and upper troposphere. We summarize the effects of lightning on atmospheric chemistry that have been published since the last major review in 2007. The estimates of NOx production by lightning (LNOx) are based on five methods: theoretical/laboratory estimates ...

Subsurface Vertical Connectivity Shapes Solute Transport to Montane Streams: Insights From Watershed‐Scale Geophysics‐Informed Modeling

Geophysical Research Letters, Volume 53, Issue 15, 16 August 2026.
Abstract Headwater catchments provide essential water and nutrients to downstream ecosystems. The timing and evolution of their transport is shaped in part by the “invisible” subsurface structure but have been largely unexplored at the watershed scale.

Scaling and Uncertainty in Soil Moisture Modelling: A Probabilistic Deep Learning Perspective

Hydrological Processes, Volume 40, Issue 8, August 2026.
A probabilistic Gaussian Mixture Long Short‐Term Memory framework is used to investigate soil moisture dynamics across the continental United States using meteorological forcings and physiographic attributes. Predictions are evaluated at unseen International Soil Moisture Network sites to ensure realistic regional transfer.

Declining Freshwater Availability in the Colorado River Basin Threatens Sustainability of Its Critical Groundwater Supplies

Geophysical Research Letters
The Colorado River Basin (CRB) is experiencing persistent aridification due to a complex interplay of natural and anthropogenic activities, resulting in significant groundwater depletion across the region. We used over two decades of NASA GRACE and GRACE

Revision of Notropis stramineus (Cope, 1865), descriptions of three new species and comments on the monophyly of Miniellus Jordan, 1882 (Pisces: Cypriniformes: Leuciscidae) [PDF]

Vertebrate Zoology
Combined analyses of molecular and morphological data support a revised classification of Notropis stramineus comprising five distinct evolutionary lineages, two for which names are available, Notropis stramineus (Cope, 1865) and N.

Increasing artificial light at night enhances salmonid predator foraging efficiency in an urbanized lake

Limnology and Oceanography, Volume 71, Issue 8, August 2026.
Abstract Artificial light at night (ALAN) poses a threat to ecosystems globally. It includes both direct and indirect light, or skyglow, which occurs when ALAN scatters in the atmosphere, extending beyond its original source. We analyzed ALAN trends in Lake Washington, WA, from 2014 to 2023 using Visible Infrared Imaging Radiometer Suite (VIIRS ...

Application of an Ensemble Stationary-Based Category-Based Scoring Support Vector Regression to Improve Drought Prediction in the Upper Colorado River Basin

Atmosphere
Recent above-normal temperatures, which exacerbated the impacts of precipitation deficits, are recognized as the primary driver of droughts in the Upper Colorado River Basin (UCRB), USA.
