Eco‐Friendly Surfactants From Pithecellobium dulce: Extraction, Characterization and Surface Activity

Journal of Surfactants and Detergents, EarlyView.
Schematic representation of the comprehensive analysis of saponins extracted form of Pithecellobium dulce (Roxb.) Benth. ABSTRACT The widespread use of synthetic surfactants in industrial and domestic applications has raised environmental concerns due to their biodegradability and ecological issues.

Insights From Two Decades of Seismicity at Columbia Glacier

Geophysical Research Letters
We use Columbia Glacier as a case study to demonstrate how seismically cataloged calving events in Alaska can track glacier evolution over two decades. By combining this catalog—a serendipitous byproduct of earthquake monitoring—with terminus positions ...

Using PlanetScope-derived time-series elevation models and orthophotos to track glacier 3D dynamics in mid-latitude mountain regions

GIScience & Remote Sensing
Assessing glacier surface height changes provides crucial insights into glacier mass loss and the impact of climate variability. Remote sensing images play a vital role in providing data points for monitoring.

Phenolic profile of selected grape (Vitis vinifera L.) varieties in the course of ripening and Botrytis cinerea infections

Journal of the Science of Food and Agriculture, EarlyView.
Abstract BACKGROUND Grapevine phenolic compounds play key roles in plant defense and wine quality. Composition depends on factors such as maturity and infections such as grey mold caused by Botrytis cinerea. Grapevines respond to infections by actively modifying their phenolic profile.

The art of avoidance: bedsite use, antipredator strategies, and predation risk in white‐tailed deer fawns

The Journal of Wildlife Management, EarlyView.
Horizontal visibility, rather than concealment cover, drove fawn bedsite use and predation risk. Greater field of view decreased the odds of coyote predation, likely by facilitated by early detection. As fawns transitioned from hiders to followers, they shifted from using dense overstory concealment to more open overstory that favored improved escape ...

Greening and Divergent Stability Responses in Central Asian Mountain Grasslands Under the Grassland Ecological Compensation Policy of China

Land Degradation &Development, EarlyView.
ABSTRACT Mountain grasslands of Central Asia, recognized as a globally significant biodiversity hotspot and a vital pastoral resource, are presently experiencing profound transformations driven by climate change and evolving grazing practices. This study investigated the multidimensional dynamics of ecosystem stability in the Bayinbuluk grassland of ...

Muon tomography for melting glaciers monitoring [PDF]

This thesis presents the development of an innovative detector for muography, aimed at monitoring glacier melting. The process of glacier melting is not completely understood and is considered a crucial parameter in view of the global warming. Muography is a widely used technique, that takes advantages of the muon flux reaching Earth surface, employed ...

Discriminating Arid Ecosystems and Tracking Desertification Dynamics: Evidence From Grain‐Size End‐Member in the Manas River Basin, Northern Tianshan Mountains

Land Degradation &Development, EarlyView.
ABSTRACT The ecosystem of the Manas River Basin, composed of mountains, oases, and deserts, constitutes an ideal natural laboratory for investigating surface processes and environmental evolution in arid regions. Elucidating the provenance, transport dynamics, and climate response mechanisms of surface sediments in this system is critical for advancing

Updating Norway’s glacial lake extents in 2023–2024 using Sentinel-1 & Sentinel-2 data and machine learning

Journal of Glaciology
Glacial lakes are increasing in number and size worldwide, posing growing risks for outburst floods. Norway’s last glacial lake inventory used semi-automatic mapping on Sentinel-2 imagery from 2018–19.

The Aridity Threshold of Soil Organic Carbon Density Along the Climate Aridity Gradient in the Alpine Ecosystem of the Qinghai‐Tibetan Plateau

Land Degradation &Development, EarlyView.
ABSTRACT Soil organic carbon density (SOCD) is a key indicator for evaluating the stability of soil carbon pools, especially in alpine ecosystems that are sensitive to climate change. However, research on the response of SOCD to different aridity gradients is still limited. Therefore, we conducted extensive sampling along different aridity gradients of
