As the Arctic continues to warm faster than the rest of the planet, evidence mounts that the
region is experiencing unprecedented environmental change. The hydrological cycle is …

Abstract The Late-Quaternary climate of Beringia remains unresolved despite the region's
role in modulating glacial-interglacial climate and as the likely conduit for human dispersal …

Shrub recruitment, a key component of vegetation dynamics beyond forests, is a highly
sensitive indicator of climate and environmental change. Warming-induced tipping points in …

Willows (Salix) are some of the most abundant shrubs in cold alpine and tundra biomes. In
alpine regions, seed dispersal is not limiting upwards willow expansion, so the upslope shift …

Excessive concentration of greenhouse gases in atmosphere emitted from human activities
has been considerably changing the world's climate, especially in the last 50 years …

Radial tree growth is sensitive to environmental conditions, making observed growth
increments an important indicator of climate change effects on forest growth. However …

Biodiversity is declining globally in response to multiple human stressors, including climate
forcing. Nonetheless, local diversity trends are inconsistent in some taxa, obscuring …

Aim Plant growth and phenology respond plastically to changing climatic conditions in both
space and time. Species‐specific levels of growth plasticity determine biogeographical …

Shrubs are expanding across a warming Arctic, evident from range expansion and
increases in biomass, stature and cover. This influences numerous aspects of Arctic …

Broad‐scale changes in arctic‐alpine vegetation and their global effects have long been
recognized and labeled one of the clearest examples of the terrestrial impacts of climate …
