Climate and Hydrogeological Controls on Water Tracks in Permafrost Landscapes

Reviews of Geophysics
AbstractClimate change drives disturbance in hydrology and geomorphology in terrestrial polar landscapes underlain by permafrost, yet measurements of, and theories to understand, these changes are limited. Water flowing from permafrost hillslopes to channels is often modulated by water tracks, zones of enhanced soil moisture in unchannelized ...

Global threats, local opportunities: ice‐related landforms provide refugia for high‐elevation plants and arthropods

Ecography, Volume 2026, Issue 9, September 2026.
Ice‐related landforms in mountain areas have been hypothesized to play a key role in the survival of cold‐adapted species threatened by climate change. However, our understanding of such landforms acting as refugia remains speculative. Here we analyse occurrence data, collected through a standardized sampling at 471 sampling points across the European ...

Resilience or reassembly: Wildfire–vegetation dynamics in rapidly warming subarctic forests of northwestern Canada

Ecosphere, Volume 17, Issue 9, September 2026.
Abstract Climate‐induced shifts in disturbance regimes are reshaping northern forest ecosystems, where tree species are at their geographic range limit. Northern Canada has warmed over twice as much as the mean global increase since 1950, providing a critical context to study climate–fire–vegetation interactions under rapid warming.

Ecological stability of zooplankton communities in changing arctic lakes over three decades

Ecology, Volume 107, Issue 9, September 2026.
Abstract In the Arctic, rapid warming is altering disturbance regimes, creating an urgent need to assess the ecological stability of these relatively pristine ecosystems. The Arctic landscape has thousands of lakes that are experiencing both gradual, persistent disturbances (e.g., warming) and increased frequency and intensity of pulse disturbances (e ...

Proximate Climate Drivers of Beaver Pond Occupancy and Range Expansion in Arctic Alaska

Global Change Biology Communications, Volume 1, Issue 3, September 2026.
To understand why beavers are colonizing the Arctic, we evaluated which climate drivers underpin beaver pond dynamics. Warm Junes, mild winters, green summers, and wet springs facilitate pond establishment. Rapid improvement in these conditions across recent decades provides mechanistic support that climate change is driving beaver colonization of the ...

Warming‐Induced Shifts in Relative Humidity Reshape Global Soil Organic Carbon Storage

Global Change Biology Communications, Volume 1, Issue 3, September 2026.
We developed a four‐dimensional deep learning framework for predicting global soil organic carbon (SOC). It generates spatially explicit, soil depth‐resolved, and temporally connected SOC estimates. ABSTRACT Soil organic carbon (SOC) underpins food production, ecosystem functioning, and climate regulation.

Woody Vegetation Dynamics Beyond the Treeline: Identifying Limiting Processes and Their Tipping Points

Global Change Biology Communications, Volume 1, Issue 3, September 2026.
Illustration of temporal trends in Arctic and alpine woody vegetation under changing growth conditions (summer temperature and winter snowpack). Upper panel: example of shrub expansion in southern France (photograph included). Greening is detected via increasing NDVI (Normalized Difference Vegetation Index).

Spatial Patterns of Soil Properties Affect Potential Range Shifts of Temperate Forest Biodiversity Under Climate Change

Global Change Biology Communications, Volume 1, Issue 3, September 2026.
Integrating edaphic properties in species distribution models reveals that climate‐driven projections may overpredict suitable habitat and range shifts of forest species. Soil heterogeneity reduces suitable habitats, suggesting more conservative responses to future warming for many species across elevational gradients.
