Study of hydrothermal processes in ice-layers subgrade under constant temperature and dynamic loading

Scientific Reports
The presence of ice-layers in the subgrade soils makes the hydrothermal state of road subgrade built in island permafrost regions more susceptible to external environmental influences.

Influence of Geomorphic Disturbance on Phenotypic Species Plasticity and Vegetation Cover in High‐Elevated Belts

Ecology and Evolution, Volume 16, Issue 3, March 2026.
Climate change increases geomorphological disturbances, which in turn affect vegetation establishment in high‐elevation areas; understanding species' responses to such disturbances is essential. We analysed vegetation across disturbed and undisturbed alpine sites to identify environmental drivers and assess species trait plasticity.

On the Limits of Alpine Plants: A Systematic Review of the Factors Behind Species' Elevational Range Limits

Ecology and Evolution, Volume 16, Issue 3, March 2026.
This systematic review of 107 studies on the factors behind the elevational range limits of alpine vascular plants shows a persistent emphasis on upper limits and abiotic factors, especially temperature, while work at lower limits is more evenly distributed across water availability, plant–plant interactions, and selection/local adaptation.

Long‐Term Effects of Freeze–Thaw Events on Ecosystem Carbon Exchange

Ecology and Evolution, Volume 16, Issue 3, March 2026.
In this work, we utilized 24 long‐term (over 10 years) observed flux tower sites to analyze the impact of freeze–thaw events on net ecosystem carbon exchange (NEE) and ecosystem respiration (RE), and explored the resistance of ecosystem carbon exchange to freeze–thaw events.

Moss diatoms show regional structuring, high potential endemism, and an inverse latitudinal diversity gradient in the Arctic

Ecography, Volume 2026, Issue 3, March 2026.
Microorganisms perform essential functions in Arctic terrestrial ecosystems. Yet, their ecology and biogeography are poorly understood, despite being necessary to predict microbial responses to future climate change. Here, we provide the first large‐scale floristic and biogeographic study of the moss diatom flora in the tundra regions of the North ...

Dendrochronology and remote sensing reveal beaver occupancy and colonization dynamics in an expanding Arctic population

Ecosphere, Volume 17, Issue 3, March 2026.
Abstract The North American beaver (Castor canadensis) is expanding its distribution in the Arctic tundra. Due to the species' capacity to engineer ecosystems, they can transform surface water dynamics and biogeochemistry, permafrost stability, vegetation composition, and impact Indigenous subsistence practices.

Alpha diversity patterns are unmatched by beta diversity across productivity gradients of the subarctic

Ecosphere, Volume 17, Issue 3, March 2026.
Abstract The mechanisms linking productivity to patterns of species richness, species prevalence, and beta diversity remain contested and may be scale‐dependent. We address productivity–diversity relationships in arthropod communities across two subarctic landscapes.

Enhanced Ultramicropore of Biomass‐Derived Porous Carbon for Efficient and Low‐Energy CO2 Capture: Integration of Adsorption and Solar Desorption

ENERGY &ENVIRONMENTAL MATERIALS, Volume 9, Issue 2, March 2026.
By increasing the ultramicropore volume of biomass‐derived porous carbon through mechanical compression and utilizing its photothermal properties, this study achieves high CO2 adsorption capacity and solar‐driven regeneration with low energy consumption, providing a novel strategy for high‐efficiency carbon capture technology.

Permafrost

, 1978
The map shows the location of the continuous permafrost zone and the discontinuous permafrost zone including areas of wide spread permafrost, areas of scattered permafrost and permafrost areas in the Cordillera. The map also indicates for six locations (Inuvik, Yellowknife, Thompson, Resolute, Rankin Inlet and Schefferville) the thickness of permafrost
