Fire regime shift reveals 17th century socio‐ecological change in the Rio Grande del Norte National Monument, New Mexico

Ecosphere, Volume 17, Issue 9, September 2026.
Abstract Humans have influenced ecosystems for millennia, and social changes can have notable ecological effects. Recent human influence on ecosystems is exemplified by the collapse of fire regimes circa 1900 in the western United States due to increased grazing, fire suppression, and declining Indigenous fire use.

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 ...

The muskox (Ovibos moschatus) in Sweden: update on a small wild population with an uncertain fate

Polar Research
Once widespread across the Holarctic region, the iconic and pre-historic muskox (Ovibos moschatus) has seen a significant range reduction, with endemic populations now restricted to North America and scattered populations introduced throughout Eurasia ...

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).

Shared and divergent rates and trajectories of Arctic vegetation community reorganization after fire and fertilization

Arctic Science
Climate warming and increasing fire frequency are reshaping Arctic vegetation communities through changes in disturbance and nutrient availability, yet whether fire and nutrient enrichment drive similar or distinct pathways of vegetation reorganization ...

Patterned-ground facilitates shrub expansion in Low Arctic tundra

Environmental Research Letters, 2013
Recent expansion of tall shrubs in Low Arctic tundra is widely seen as a response to climate warming, but shrubification is not occurring as a simple function of regional climate trends.

Climate Warming Promotes Carbon Sequestration and Weathering in Tundra Landscapes and Alters Carbon Chemistry of Subarctic Lakes in Scandinavia

Global Change Biology Communications, Volume 1, Issue 3, September 2026.
Climate‐induced vegetation greening (NDVImax) stimulated C‐sequestration in subarctic catchments by 10%–85% during the last decades. Increases in weathering and declines in non‐marine SO4 atmospheric deposits were identified as the main drivers of decadal increases in inorganic C (ICalk) run‐off to subarctic lakes.

Research Priorities for Robust Climate Assessments in the United States

Earth's Future, Volume 14, Issue 9, September 2026.
Abstract Scientific assessments play a critical role in synthesizing evidence to support evidence‐based decision‐making in many sectors and topics. For climate change, large‐scale assessments like the Intergovernmental Panel on Climate Change (IPCC) and the United States (U.S.) National Climate Assessment (NCA) reports help many different users—from ...

Long-term alpine summit vegetation cover change: Divergent trajectories driven by climate warming and fire

Arctic, Antarctic, and Alpine Research
Alpine summit vegetation, the highest point of species geographical distributions, is vulnerable to climate change (thermal niche contraction), and there is evidence of change in Northern Hemisphere summits. However, summits are experiencing multifaceted

Local Species Loss and Retraction Across the Alps and Apennines: Recent Thermophilization and Diversity Changes of the Alpine Flora

Journal of Biogeography, Volume 53, Issue 9, September 2026.
ABSTRACT Aim The European alpine life zone is a recognized biodiversity hotspot, currently impacted by warming temperatures.
