Hydrological controls on diurnal ice flow variability in valley glaciers [PDF]

open access: yes, 2005
This paper uses a combination of field data and three-dimensional modeling to investigate the spatial variability in basal conditions required to induce observed fluctuations in diurnal ice velocity at Haut Glacier d'Arolla, Switzerland.

Atmospheric Water Harvesting Through Polymer Hydrogel Sorbents: Materials Chemistry, Design Strategies, and Applications

open access: yesAdvanced Science, EarlyView.
Polymer‐based hydrogels have emerged as promising materials for atmospheric water harvesting (AWH) due to their high water affinity, tunable network structure, and excellent moisture adsorption‐desorption performance. Functional hydrogel systems enable efficient water capture and controlled release under low‐energy conditions, offering a sustainable ...

Management of the Tongass National Forest in Southeast Alaska increases extinction risk of island endemics

open access: yesGlobal Ecology and Conservation
After decades of clearcut logging the most productive old-growth forests, the Tongass National Forest developed a new forest plan in 1997 with expectations of maintaining viable populations of native wildlife species.

Black bear density in Glacier National Park, Montana

open access: yesWildlife Society Bulletin, 2014
We report the first abundance and density estimates for American black bears (Ursus americanus) in Glacier National Park (NP), Montana, USA. We used data from 2 independent and concurrent noninvasive genetic sampling methods—hair traps and bear rubs ...

An Optimized Freeze‐Dry Multimodal Workflow for Sequential Micro‐CT Imaging, Histology, and Molecular Profiling: A Use Case in Human Liver Fibrosis

open access: yesAdvanced Science, EarlyView.
Optimized freeze‐drying and eosin staining deliver artifact‐free micro‐CT images of liver tissue at near‐histological detail, then hand the same specimen back for sectioning, staining, and sequencing. Fibrotic volume distinguishes normal liver from cirrhosis, while preserved RNA reveals inflammatory gene upregulation—one biopsy, three dimensions, and a

Nonlinear threshold effects of environmental drivers on vegetation cover in mountain ecosystems: From constraint mechanisms to adaptive management

open access: yesEcological Indicators
Based on a nonlinear theoretical framework, this study systematically reveals the spatiotemporal evolution characteristics of fractional vegetation cover (FVC) in the Qilian Mountains and its environmental constraints, providing scientific support for ...

Freestanding Hierarchical‐Porous BCZT Thin Films Enable Efficient Ultrasonic Energy Harvesting in Soft Tissue

open access: yesAdvanced Science, EarlyView.
Freestanding hierarchical‐porous BCZT thin films integrate a compliant porous surface with a dense piezoceramic backbone to balance mechanical reliability, voltage sensitivity, and acoustic coupling. The films enable stable wearable pulse‐wave monitoring and enhanced tissue‐coupled ultrasonic energy harvesting, offering a promising route toward soft ...

Revising the tectonic chronology of East–West Antarctica since the breakup of East Gondwana

open access: yesNature Communications
East–West Antarctic separation from ~43–11 Ma is well-documented through marine magnetic anomalies in the western Ross Sea, yet multiple lines of evidence suggest earlier extension, including Victoria Land uplift (~55–50 Ma) and reconstruction gaps ...

Global glacier changes

open access: yes, 2008
Changes in glaciers and ice caps provide some of the clearest evidence of climate change, and as such they constitute key variables for early detection strategies in global climate-related observations.
