Shrubs have increased in abundance and dominance in arctic and alpine regions in recent
decades. This often dramatic change, likely due to climate warming, has the potential to alter …

Recent research using repeat photography, long-term ecological monitoring and
dendrochronology has documented shrub expansion in arctic, high-latitude and alpine …

Deciduous shrubs are expected to rapidly expand in the Arctic during the coming decades
due to climate warming. A transition towards more shrub-dominated tundra may have large …

The circumpolar expansion of woody deciduous shrubs in arctic tundra alters key ecosystem
properties including carbon balance and hydrology. However, landscape‐scale patterns …

In order to characterize shrub response near the treeline in Eastern Nunavik (Québec), a
region under extensive warming since the 1990s, we compared two series (1964 and 2003) …

The effects of climate change on Arctic ecosystems can range between various
spatiotemporal scales and may include shifts in population distribution, community …

Enhanced shrub growth and expansion are widespread responses to climate warming in
many arctic and alpine ecosystems. Warmer temperatures and shrub expansion could …

Enhanced shrub growth in a warming alpine climate has potential far-reaching implications,
including soil nutrient cycling, carbon storage, or water and surface energy exchanges …

Arctic ecosystems are important carbon sinks. Increasing temperatures in these regions
might stimulate soil carbon release. Evidence suggests that deciduous shrubs might …

Iceland, located in the climatologically sensitive subarctic zone, is one of the key areas for
studying climate change and the current Arctic warming. Poor and rich heathland covers …
