Wood anatomical traits of xylem are the characteristics of tree rings at cellular and
subcellular scales providing important insights on structural features and their linkage to the …

Wildfires are relatively rare in subarctic tundra ecosystems, but they can strongly change
ecosystem properties. Short-term fire effects on subarctic tundra vegetation are well …

Arctic and alpine ecosystems are strongly affected by rapidly changing environmental
conditions, resulting in profound vegetation shifts, which are highly heterogeneous and hard …

Widespread shrubification across the Arctic has been generally attributed to increasing air
temperatures, but responses vary across species and sites. Wood structures related to the …

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 …

Abstract Background and Aims Trees adjust the configuration of their conductive system in
response to changes in water availability, maximizing efficiency in wet environments and …

Warming may lead to a cover increase of tundra shrubs and a north‐and upward shift of
treelines. The latter may be inhibited by a densification of shrub stands. However, the …

Introduction Mean xylem vessel or tracheid area have been demonstrated to represent
powerful proxies to better understand the response of woody plants to changing climatic …

Vegetation is changing across the Arctic in response to increasing temperatures, which may
influence archaeological sites in the region. At the moment, very little is known about how …

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