Exposure to warming and CO2 enrichment promotes greater above-ground biomass, nitrogen, phosphorus and arbuscular mycorrhizal colonization in newly established grasslands
In view of the projected increase in global air temperature and CO2 concentration, the effects of climatic changes on biomass production, CO2 fluxes and arbuscular mycorrhizal fungi (AMF) colonization in newly es...

Spatial variability and controls over biomass stocks, carbon fluxes, and resource-use efficiencies across forest ecosystems
Stand age, water availability, and the length of the warm period are the most influencing controls of forest structure, functioning, and efficiency.

Article
Nutrient availability and climate as the main determinants of the ratio of biomass to NPP in woody and non-woody forest compartments
Once the effect of stand age has been taken into account, nutrient availability and climate play a crucial role in determining the B:NPPs of woody and non-woody tissues.

Global vegetation’s CO2 uptake
Multiple lines of evidence reveal that annual maximum photosynthesis across the world has been increasing over the past 30 years, adding crucial new information on the processes influencing the land carbon sin...

A meta-analysis of 1,119 manipulative experiments on terrestrial carbon-cycling responses to global change
Direct quantification of terrestrial biosphere responses to global change is crucial for projections of future climate change in Earth system models. Here, we synthesized ecosystem carbon-cycling data from 1,1...

Mesh bags underestimated arbuscular mycorrhizal abundance but captured fertilization effects in a mesocosm experiment
Ingrowth bags are widely used to estimate mycorrhizal growth and dynamics. However, it remains unclear to what extent they reflect the surrounding soil, and how this varies with environmental conditions.

A systemic overreaction to years versus decades of warming in a subarctic grassland ecosystem
Temperature governs most biotic processes, yet we know little about how warming affects whole ecosystems. Here we examined the responses of 128 components of a subarctic grassland to either 5–8 or >50 years of...

Post-drought rewetting triggers substantial K release and shifts in leaf stoichiometry in managed and abandoned mountain grasslands
When soil is rewetted after drought, typically a transient pulse of mineralization and other microbial processes occur. This “Birch effect” translates into a temporarily elevated soil carbon dioxide efflux (SC...

Open AccessRegulation of nitrogen fixation from free-living organisms in soil and leaf litter of two tropical forests of the Guiana shield
Biological fixation of atmospheric nitrogen (N2) is the main pathway for introducing N into unmanaged ecosystems. While recent estimates suggest that free-living N fixation (FLNF) accounts for the majority of N f...

Increased tree growth following long-term optimised fertiliser application indirectly alters soil properties in a boreal forest
It is well established that nutrient addition influences ecosystem features such as productivity, carbon storage, soil acidification and biodiversity. Less studied are long-term effects of sustained fertiliser...

Open AccessField experiments underestimate aboveground biomass response to drought
Researchers use both experiments and observations to study the impacts of climate change on ecosystems, but results from these contrasting approaches have not been systematically compared for droughts. Using a...
