Modeled Subsidence of Permafrost Terrain 2025–2050: North‐Central Alaska

Permafrost and Periglacial Processes, EarlyView.
ABSTRACT A large fraction of the Alaska terrain is underlain by regolith that contains excess ice (ice that in volume exceeds the natural pore space). Possible loss of excess ice would lead to ground subsidence, which in turn would disturb and destabilize the ground surface.

Disposition Model for Permafrost Degradation in Mountainous Regions

Permafrost and Periglacial Processes, EarlyView.
ABSTRACT Permafrost is a widespread thermal phenomenon in Arctic and high mountain regions that, in combination with steep terrain, exerts a key control on slope stability. Its degradation in response to climatic warming can modify the likelihood and timing of rockfall, debris flow and related mass movements. Robust information on the current state and

Depositional and Hydrological Relationships Between Buried Dead Ice and the Active Layer in the McMurdo Dry Valleys, Antarctica: A Study of Sediment Geochemistry and Cation Concentrations

Permafrost and Periglacial Processes, EarlyView.
ABSTRACT The McMurdo Dry Valleys, the largest ice‐free region in Antarctica, are home to a cold‐desert hydrologic system of glaciers, snowbanks, streams, and lakes. Freshwater is also stored as dead glacial ice, which is poorly constrained in terms of ion concentrations and interactions with both in situ and overlying sediments.

Integrating SfM, LiDAR and TLS for High‐Resolution Monitoring of Palsa Surface Changes and Degradation Dynamics

Permafrost and Periglacial Processes, EarlyView.
ABSTRACT Understanding fine‐scale surface changes is crucial for quantifying ecosystem dynamics and detecting landscape changes. Palsas, comparably small peatland elevations with an ice‐rich permafrost core, undergo natural cycles of growth and degradation. They can also serve as indicators of climate change in subarctic regions. Because they typically

Conservation gap analysis for wild grapevines (Vitis L.) of the Americas

PLANTS, PEOPLE, PLANET, EarlyView.
Wild grapevines (Vitis L.) native to the Americas are ecologically and culturally important plants that are also critical to the global cultivated grape industry as sources of traits for crop innovation, but many of these species are poorly documented and insufficiently conserved.

Enhance food plant diversity conservation and use through greater coordination between genebanks and botanic gardens

PLANTS, PEOPLE, PLANET, EarlyView.
Food plants are vital to human and planetary health, but their diversity is threatened, making food security, nutrition, and environmental goals more difficult to achieve. Food plant diversity conservation, research, and education can be enhanced through collaboration between sectors, including genebanks and botanic gardens, which possess complementary

A Scalable Large Language Model‐Aided Approach for Mining Plant‐Compound Pairs From Scientific Literature

PLANTS, PEOPLE, PLANET, EarlyView.
Understanding plant chemicals is vital for medicine and agriculture, but global data remain fragmented and biased. We developed an AI‐powered tool to automatically extract plant‐compound information from scientific literature at scale and low cost. Our analysis revealed significant knowledge gaps, particularly in the Southern Hemisphere. By efficiently

Climate‐smart land management: Greenhouse gas outcomes and social and economic pathways to adoption

PLANTS, PEOPLE, PLANET, EarlyView.
Climate change poses one of the greatest threats to natural and working lands, reducing the resilience of agricultural and forest productivity. Because land management is a leading source of greenhouse gas (GHG) emissions, climate‐smart management practices are being implemented to reduce net emissions while sustaining yields.
