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.
Microplastics are tiny plastic fragments resulted from runoff and weathering breakdown of larger plastics debris. They represent an emerging concern for marine ecosystems. Microplastics impacts on aquatic life are little studied. These small particles coul ...
Within the benthic realm life carpets the sedimentary surface of all aquatic ecosystems including the oceans, lakes, rivers and streams. Microorganisms of all types, bacteria, archaea and eukaryotes, inhabit these environments and through their metabolic a ...
Floating macrophytes, including water hyacinth (Eichhornia crassipes), are dominant invasive organisms in tropical aquatic systems, and they may play an important role in modifying the gas exchange between water and the atmosphere. However, these systems a ...
Introduction-Thermal pollution can have considerable influence on water temperature in freshwater systems notably affecting stratification [Kirillin et al., 2013]. Consequences can be seen across the entire aquatic food web [Barnett, 1971; Cairns, 1971; Sy ...
Sorption of organic molecules to mineral surfaces is an important control upon the aquatic carbon (C) cycle. Organo-mineral interactions are known to regulate the transport and burial of C within inland waters, yet the mechanisms that underlie these proces ...
Water retention in reservoirs and concentrated turbine operations allow electricity to be produced on demand. Sudden opening and closing of the turbines can produce highly unsteady flow conditions in the river downstream of the tailrace channel, the so-cal ...
Most microorganisms live in environments where nutrients are limited and fluctuate over time. Cells respond to nutrient fluctuations by sensing and adapting their physiological state. Recent studies suggest phenotypic heterogeneity(1) in isogenic populatio ...
Viruses are ubiquitous in aquatic ecosystems where they significantly contribute to microbial mortality. In glacier-fed turbid lakes, however, viruses not only encounter low host abundances, but also a high number of suspended mineral particles introduced ...
The fragility of thin Clark-type glass microelectrodes used in aquatic eddy covariance measurements of benthic oxygen fluxes is a challenge when using this powerful technique. This study presents a new fast-responding dual oxygen-temperature sensor for edd ...
Species declines due to changing environmental conditions or anthropogenic influences such as fisheries harvest as well as species introductions probably have consequences beyond the species by also altering their food webs. The scope of the effect on the ...
