A novel dual-polarization SAR-based method for high-accuracy 768 km river mapping in steep mountainous regions

open access: yesInternational Journal of Applied Earth Observations and Geoinformation
Accurate river mapping in steep mountains is essential for disaster warning, water resources, and ecological management, yet remains challenging due to complex terrain and dynamic hydrology.

Effects of Climate Change on Avalanche Accidents and Survival

open access: yesFrontiers in Physiology, 2021
Avalanches are major natural hazards in snow-covered mountains, threatening people and infrastructure. With ongoing climate change, the frequency and types of snow avalanches may change, affecting the rates of avalanche burial and survival. With a wetter

Historical data reveal earlier flowering under environmental change

open access: yesNordic Journal of Botany, EarlyView.
Global temperatures have risen ~ 1.1°C since the 1800s and the mean annual air temperature in the Arctic has increased by nearly four times the global average. Temperature has a significant effect on fundamental life‐cycle events of flora and fauna. With temperatures increasing, Arctic plants are expected to shift their active periods accordingly, with

Evaluating the Sensitivity of Polarimetric Features Related to Rotation Domain and Mapping Chinese Fir AGB Using Quad-Polarimetric SAR Images

open access: yesRemote Sensing, 2023
Unaffected by cloud cover and solar illumination, synthetic aperture radar (SAR) images coupled with quad-polarimetric techniques have significant potential for mapping forest aboveground biomass (AGB) in the mountains of southern China.

The epigenetic landscape of plant defense: Unlocking nature's toolkit for new plant protection

open access: yesNew Plant Protection, EarlyView.
This review examines how epigenetic mechanisms regulate plant immune gene activation, repression, and priming, then links these natural regulatory layers to emerging epigenetic editing, discussing their potential for precise, heritable crop protection and the challenges.

Identification of initial vegetation and habitat changes in small temperate fens using remote sensing

open access: yesRemote Sensing in Ecology and Conservation, EarlyView.
Temperate fens with only incipient, subtle signs of deterioration can be reliably identified using Sentinel‐2 and aerial imagery, which sensitively detect early productivity‐related structural changes. Abstract Small temperate fens rank among the most endangered habitats in temperate Europe.

Improved Cerrado Wetland Mapping Through Seasonal Moisture Metrics, Terrain Information and Semantic Segmentation

open access: yesRemote Sensing in Ecology and Conservation, EarlyView.
Brazil's Cerrado valley wetlands—swamp savanna and gallery forest—are highly important for the biome's water cycle and carbon storage and are susceptible to degradation from the impacts of land use expansion and the climate crisis. In support of their detailed monitoring and assessment, we developed and tested a transferable mapping approach that ...

HLA‐A*11:01 Identifies Patients at Risk for Persistent Viraemia and Advanced Fibrosis in HDV Infection

open access: yesAlimentary Pharmacology &Therapeutics, EarlyView.
The HLA‐A*11:01 allele is associated with persistent viraemia and advanced liver fibrosis in HDV infection. HLA‐A*11:01 carriers exhibit a reduced T‐cell repertoire, suggesting a narrower T‐cell response to the infection. ABSTRACT Background Hepatitis delta virus (HDV) infection causes the most severe form of viral hepatitis, with highly heterogeneous ...
