Switzerland has about 6,000 shooting ranges, of which 2,000 are still in use. These activities generate a significant lead pollution. FOEN estimated 200 tons of lead is fired each year. This Master Project has been realized with the consultancy office CSD ...
We present analyses of new and previously published estimates of total (vegetation plus soil) carbon storage on exposed continental shelves during the LGM. Carbon stock estimates from environmental reconstructions vary from 113 to 202 Pg C. Estimates from ...
Since a few decades, the balance of the nitrogen (N) cycle has been deeply disturbed by human activies. The global impact of these activities on the N cycle can be described as a doubling of the transfer from the vast and unreactive atmospheric pool to bio ...
Theoretical advances and short-term experimental studies have furthered our understanding of how ecosystems respond to perturbation. However, there are few wellreplicated experimental studies that allow an assessment of long-term responses. Results from a ...
In temperate forests, soils are the main sink for atmospheric N deposition. The main processes proposed for N retention are microbial and abiotic immobilization in soil organic matter. The relative importance of these processes as well as the kind of resul ...
In temperate forest ecosystems, soil acts as a major sink for atmospheric N deposition. A 15N labeling experiment in a hardwood forest on calcareous fluvisol was performed to study the processes involved. Low amounts of ammonium (15NH4 +) or nitrate (15NO3 ...
Cutover peatlands cover large surfaces of high potential value for biodiversity and carbon sequestration function if successfully restored but the evaluation of restoration success is not straighforward. We assessed the bioindicator value of organic mat ...
We examine the effect of natural differences in soil temperature at two locations distant by approximately 500 m in the frozen scree of La Plagne en Chartreuse (Savoy, France). We determined humus properties, soil organisms and biologically mediated soil-f ...
Increased demand for biofuels is expected to produce changes in the present land-use configuration. Furthermore there is a growing concern about the effect of land-use change on biodiversity, food supply, soil and water quality. Biofuels production on curr ...
Understanding and forecasting changes in plant communities, ecosystem properties, and their associated services requires a mechanistic link between community shifts and modifications in ecosystem properties. In this study, we test the hypothesis that plant ...
