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 ...
Methane (CH4) is a major greenhouse gas whose global warming potential is 23 times more important than carbon dioxide (CO2). CH4 concentrations have steadily increased since the beginning of the industrial era, reaching an unprecedent level (almost 1800 pp ...
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 ...
CNS regeneration is limited by lesion-induced neuronal apoptosis and an environment inhibiting axonal elongation. Inhibition of ROCK has been previously shown to promote regeneration in retinal ganglion cells (RGC) whereas Cdk5 inhibition mainly promoted s ...
Due to human activities, organic pollutants are spilled to the environment where they threaten public health, often as contaminants of soil or groundwater. Living organisms are able to transform or mineralize many organic pollutants, and bioremediation tec ...
This study investigates the influence of petroleum hydrocarbons on a microbial community in the vadose zone under field conditions. An artificial hydrocarbon mixture consisting of volatile and semi-volatile compounds similar to jet-fuel was emplaced in a p ...
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 ...
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 ...
Phytoextraction is an in situ decontamination technique using metal accumulating plants and appropriate soil amendments to transport and concentrate metals from the soil into the aboveground parts of plants, which are harvested with conventional agricultur ...
The study was performed in the Sahelian part of Burkina Faso. The country is subject to difficult climatic conditions, a strong demographic growth and a continuous decrease in soil fertility. The resulting degradation affects the processes which govern eco ...
