Abstract Grasslands on the Qinghai–Tibetan Plateau (QTP) foster biodiversity, store carbon,
maintain productivity and support pastoral livelihoods. These systems are being altered by …

Aim Soil nitrogen (N) cycling is critical to the productivity of terrestrial ecosystems. However,
the impact of global change factors (GCFs) on the microbial mediators of N cycling pathways …

Global climate warming may induce a positive feedback through increasing soil carbon (C)
release to the atmosphere. Although warming can affect both C input to and output from soil …

Nutrient enrichment is a major global change component that often disrupts the relationship
between aboveground biodiversity and ecosystem functions by promoting species …

Arbuscular mycorrhizal fungi (AMF) significantly contribute to plant resource acquisition and
play important roles in mediating plant interactions and soil carbon (C) dynamics. However …

Despite the increasing impact of atmospheric nitrogen (N) deposition on terrestrial
greenhouse gas (GHG) budget, through driving both the net atmospheric CO2 exchange …

Global potent greenhouse gas nitrous oxide (N2O) emissions from soil are accelerating, with
increases in the proportion of reactive nitrogen emitted as N2O, ie, N2O emission factor (EF) …

Anthropogenic nitrogen (N) input has overtaken natural N fixation as the leading source of
reactive N, and can profoundly alter the structure and functions of terrestrial ecosystems. N …

Ecosystem functions, such as soil nitrogen cycling, are being altered by climate change. The
responses of soil (de) nitrification to climate change are different and sometimes opposite …

Multiple lines of existing evidence suggest that increasing CO2 emission from soils in
response to rising temperature could accelerate global warming. However, in experimental …
