Arctic warming and permafrost loss modify northern ecosystems through soil subsidence, changes in soil hydrology, nutrient availability and vegetation succession. In particular, warming and soil moisture conditions influence Arctic tundra vegetation production and distribution: wetter soil conditions favor sedge expansion and drier soil conditions drive woody shrub expansion.

A l’occasion de la défense de thèse d’Elisabeth Mauclet « Influence of permafrost degradation on the mineral nutrient cycling by Arctic tundra vegetation »  nous avons le plaisir d’accueillir deux membres du jury pour un séminaire et un échange entre 12h30 et 14h le 17 mai dans la salle Océan

Agricultural land use is a major driver of global climate and environmental change. Remote sensing is used to produce wall-to-wall maps of cropland, crop types, and land management indicators across consolidated agricultural systems across the globe.

The quantification and monitoring of soil organic carbon (SOC) in croplands is crucial in a context of effective and precise agricultural management. Conventional methods to assess SOC changes pose some limitations on time and labor consumption to efficiently assess SOC distributions and dynamics in a spatial and temporal context.

The phage replication cycle begins with its adsorption to its host and ends with the release of new virions upon bacterial lysis. These steps are important, not only for the proper conduct of the phage life cycle, but also because proteins mediating attachment and lysis have a significant biotechnological potential.
