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 ...

Disorder‐Induced Extremely Low Thermal Conductivity of Graphite Fluoride

Advanced Science, Volume 13, Issue 44, 7 August 2026.
This article investigates the effect of fluorination on the thermal conductivity of graphite fluoride, demonstrating the relationship between structural modification and thermal conductivity in an extreme case. The record‐low through‐plane thermal conductivity measured in exfoliated graphite fluoride flakes was found to correlate with the wide ...

Association of Left Angular Gyrus‐Right Middle Frontal Gyrus Functional Connectivity With Insomnia Severity in Major Depressive Disorder: Evidence From the DIRECT Consortium

CNS Neuroscience &Therapeutics, Volume 32, Issue 8, August 2026.
Preferential alterations in insomnia‐related AG–MFG connectivity in MDD highlight sleep‐associated neural mechanisms, although disentangling these connectivity changes from depression severity remains challenging. Local aberrations in regional brain function primarily differentiate patients with MDD from healthy controls.

Shifts in Southeastern Bat Communities Driven by Landscape Composition Rather Than Ecological Release

Ecology and Evolution, Volume 16, Issue 8, August 2026.
Using 25 years of capture data from Fort Campbell Military Installation, we evaluated whether white‐nose syndrome (WNS)‐driven declines in susceptible bats were followed by increases in non‐susceptible species (ecological release) versus shifts driven by land use change, at the installation and site specific spatial scales.

Flume experiments on macro‐roughness elements: Hydraulic response and potential influences on flood risk and habitat diversity

Earth Surface Processes and Landforms, Volume 51, Issue 8, August 2026.
Physical modelling of macro‐roughness elements for river restoration showed that backwater rise depends mostly on the relative structure width and approaching flow Froude number, with only minor differences among designs. Internal geometry modulated turbulent kinetic energy and flow partition between gap and wake.

Modelling Flood‐Induced Riparian Vegetation Disturbance and Hydro‐Morphodynamic Feedbacks

Earth Surface Processes and Landforms, Volume 51, Issue 8, August 2026.
A process‐based framework links flood‐induced vegetation disturbance to hydro‐morphodynamic feedback by separating mechanical failure from postfailure outcomes, explaining spatial distribution patterns of washout, burial and localized embankment erosion during the 2019 Chikuma River flood.

Hydraulic reconstruction of catastrophic drainage from the Late Glacial, Lake Fraser, British Columbia, Canada

Journal of Quaternary Science, Volume 41, Issue 6, Page 873-887, August 2026.
ABSTRACT Glacial Lake Fraser, which formed in British Columbia against the retreating Cordilleran Ice Sheet, stored ~520 km3 of water before its near‐total drainage into the Salish Sea during an outburst flood event. Despite the impact of the outburst flood on sediment transport and landscape evolution in the Fraser River valley, its peak discharge and

Detecting social‐ecological fit in Natura 2000 governance and management: Evidence from LIFE projects focused on forest protected habitat types

People and Nature, Volume 8, Issue 8, Page 2521-2540, August 2026.
Abstract Protected areas represent complex social‐ecological systems that require governance and management approaches that valorise and enhance positive relationships between people and nature. This study analyses the alignment between social and ecological systems to detect the social‐ecological fit of projects focused on biodiversity conservation ...
