Response of temperate grasslands at different altitudes to simulated summer drought differed but scaled with annual precipitation
temperate grasslands simulated summer drought annual precipitation
2010/1/21
Water is an important resource for plant life. Since climate scenarios for Switzerland predict an average reduction of 20% in summer precipitation until 2070, understanding ecosystem responses to wate...
Biodiversity for multifunctional grasslands:equal productivity in high-diversity low-input and low-diversity high-input systems
Biodiversity multifunctional grasslands equal productivity high-diversity low-input
2010/1/20
Modern grassland management seeks to provide many ecosystem services and experimental studies in resource-poor grasslands have shown a positive relationship between plant species richness and a variet...
Biomass production in experimental grasslands of different species richness during three years of climate warming
Biomass production experimental grasslands species richness climate warming
2010/1/15
Here we report on the single and combined impacts of climate warming and species richness on the biomass production in experimental grassland communities. Projections of a future warmer climate have s...
Variability of annual CO2 exchange from Dutch grasslands
Variability annual CO2 exchange Dutch grasslands
2010/1/14
An intercomparison is made of the Net Ecosystem Exchange of CO2, NEE, for eight Dutch grassland sites: four natural grasslands, two production grasslands and two meteorological stations within a rotat...
Community shifts and carbon translocation within metabolically-active rhizosphere microorganisms in grasslands under elevated CO2
Community shifts carbon translocation metabolically-active rhizosphere microorganisms
2010/1/14
The aim of this study was to identify the microbial communities that are actively involved in the assimilation of rhizosphere-C and are most sensitive in their activity to elevated atmospheric CO2 in ...
Long-term steady state 13C labelling to investigate soil carbon turnover in grasslands
Long-term steady state 13C soil carbon turnover grasslands
2010/1/14
We have set up a facility allowing steady state 13CO2 labeling of short stature vegetation (12 m2) for several years. 13C labelling is obtained by scrubbing the CO2 from outdoors air with a self-regen...
