Posez n’importe quelle question sur les cours, conférences, exercices, recherches, actualités, etc. de l’EPFL ou essayez les exemples de questions ci-dessous.
AVERTISSEMENT : Le chatbot Graph n'est pas programmé pour fournir des réponses explicites ou catégoriques à vos questions. Il transforme plutôt vos questions en demandes API qui sont distribuées aux différents services informatiques officiellement administrés par l'EPFL. Son but est uniquement de collecter et de recommander des références pertinentes à des contenus que vous pouvez explorer pour vous aider à répondre à vos questions.
Near natural floodplain ecosystems are not only stressed by frequent inundations over a year but also by periodical droughts in summer due to their reduced water retention capacity. To maintain floodplain habitats as biodiversity hotspots, a stable soil st ...
Although stream ecosystems are recognized as an important component of the global carbon cycle, the impacts of climate-induced hydrological extremes on carbon fluxes in stream networks remain unclear. Using continuous measurements of ecosystem metabolism, ...
Petroleum is produced by thermal decay of buried organic material over millions of years. Petroleum oilfield ecosystems represent resource of reduced carbon which favours microbial growth. Therefore, it is obvious that many microorganisms have adapted to h ...
Although stream ecosystems are recognized as an important component of the global carbon cycle, the impact of climate-induced hydrological changes on carbon fluxes in stream networks remain unclear. We will discuss the effects of changes in snowmelt hydrol ...
The movement of water, matter, organisms, and energy can be altered substantially at ecohydrological interfaces, the dynamic transition zones that often develop within ecotones or boundaries between adjacent ecosystems. Interdisciplinary research over the ...
In the context of climatic uncertainty and potential climatic change, incorporating climatic variability and change in eco-hydrological analysis, as well as understanding the impact of such variability on ecosystems, is of crucial importance. The latter is ...
Scaling aquatic ecosystem processes like nutrient removal is critical for assessing the importance of streams and rivers to watershed nutrient export. We used pulse NH4+ enrichment experiments and measured net NH4+ uptake in 7 streams throughout a mountain ...
Tropical forest conversion to agricultural land leads to a strong decrease of soil organic carbon (SOC) stocks. While the decrease of the soil C sequestration function is easy to measure, the impacts of SOC losses on soil fertility remain unclear. Especial ...
Analysis of chlorophyll-a map from remote sensing satellite data (MERIS) showed a consistent low concentration biomass in the middle of Lake Geneva for about two weeks in autumn 2009. A three dimensional hydrodynamic model (Delft3D-flow) validated with tem ...
Stream ecosystem metabolism modulates organic carbon (OC) cycling in rivers and regulates downstream OC fluxes. Climate-change scenarios predict precipitation to shift from snow towards rain in alpine ecosystems, however consequences of this shift to strea ...
