Tundra vegetation productivity and composition are responding rapidly to climatic changes
in the Arctic. These changes can, in turn, mitigate or amplify permafrost thaw. In this Review …

Vegetation composition shifts, and in particular, shrub expansion across the Arctic tundra
are some of the most important and widely observed responses of high-latitude ecosystems …

Chapter 2, building on prior assessments, provides a global assessment of the observed
impacts and projected risks of climate change to terrestrial and freshwater ecosystems …

The effects of plants on the biosphere, atmosphere and geosphere are key determinants of
terrestrial ecosystem functioning. However, despite substantial progress made regarding …

In the context of a recent massive increase in research on plant root functions and their
impact on the environment, root ecologists currently face many important challenges to keep …

Under a warming climate, degrading permafrost profoundly and extensively affects arctic
and alpine ecology. However, most existing relevant studies are more focused on the …

Remotely sensed biomass carbon density maps are widely used for myriad scientific and
policy applications, but all remain limited in scope. They often only represent a single …

Global change is altering species distributions and thus interactions among organisms.
Organisms live in concert with thousands of other species, some beneficial, some …

Ecosystem functioning relies heavily on below‐ground processes, which are largely
regulated by plant fine‐roots and their functional traits. However, our knowledge of fine‐root …

Input of labile carbon may accelerate the decomposition of existing soil organic matter
(priming effect), with the priming intensity depending on changes in soil nitrogen availability …
