Background Knowledge of biological and climatic controls in terrestrial nitrogen (N) cycling
within and across ecosystems is central to understanding global patterns of key ecosystem …

The pattern of a few abundant species and many rarer species is a defining characteristic of
communities worldwide. These abundant species are often referred to as dominant species …

Nitrogen (N) and phosphorus (P), either individually or in combination, have been
demonstrated to limit biomass production in terrestrial ecosystems. Field studies have been …

Carbon storage in vegetation and soil underpins climate regulation through carbon
sequestration. Because plant species differ in their ability to capture, store and release …

Climate change is expected to cause extensive vegetation changes in the Arctic: deciduous
shrubs are already expanding, in response to climate warming. The results from transect …

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 …

Climate warming is leading to shrub expansion in Arctic tundra. Shrubs form ectomycorrhizal
(ECM) associations with soil fungi that are central to ecosystem carbon balance as …

Aims Co-limitation of ecosystem productivity by nitrogen (N) and phosphorus (P) is gaining
increasing recognition, but how co-limitation through N and P interactions differs among …

Fire causes dramatic short-term changes in vegetation and ecosystem function, and may
promote rapid vegetation change by creating recruitment opportunities. Climate warming …

Growing season conditions are widely recognized as the main driver for tundra shrub radial
growth, but the effects of winter warming and snow remain an open question. Here, we …
