Soil carbon breakdown
Model projections of future climate are highly sensitive to the assumed response of organic matter decomposition to changes in temperature. Incubation experiments on North American soils suggest that the decis...

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...

Climate extremes and the carbon cycle
The effects of climate extremes such as droughts or storms on the carbon cycle of ecosystems are investigated; such extremes can decrease regional carbon stocks.

Asymmetric effects of daytime and night-time warming on Northern Hemisphere vegetation
Correlations between the maximum and minimum daily temperatures and a vegetation index in the Northern Hemisphere suggest that asymmetric diurnal warming (faster warming of the land surface during the night th...

Human-induced nitrogen–phosphorus imbalances alter natural and managed ecosystems across the globe
The availability of carbon from rising atmospheric carbon dioxide levels and of nitrogen from various human-induced inputs to ecosystems is continuously increasing; however, these increases are not paralleled ...

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.

Open AccessLeaf onset in the northern hemisphere triggered by daytime temperature
Recent warming significantly advanced leaf onset in the northern hemisphere. This signal cannot be accurately reproduced by current models parameterized by daily mean temperature (Tmean). Here using in situ obser...

Open AccessAre variations in heterotrophic soil respiration related to changes in substrate availability and microbial biomass carbon in the subtropical forests?
Soil temperature and moisture are widely-recognized controlling factors on heterotrophic soil respiration (Rh), although they often explain only a portion of Rh variability. How other soil physicochemical and mic...

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.

Open AccessRemotely-sensed detection of effects of extreme droughts on gross primary production
Severe droughts strongly impact photosynthesis (GPP), and satellite imagery has yet to demonstrate its ability to detect drought effects. Especially changes in vegetation functioning when vegetation state rema...

Icelandic grasslands as long-term C sinks under elevated organic N inputs
About 10% of the anthropogenic CO2 emissions have been absorbed by northern terrestrial ecosystems during the past decades. It has been hypothesized that part of this increasing carbon (C) sink is caused by the a...

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...

Nitrogen and phosphorus constrain the CO2 fertilization of global plant biomass
Elevated CO2 (eCO2) experiments provide critical information to quantify the effects of rising CO2 on vegetation1–6. Many eCO2 experiments suggest that nutrient limitations modulate the local magnitude of the eCO

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...
