My Marie Curie project

The majority of the Earth’s terrestrial carbon (C) is stored in the soil as organic carbon, at quantities more than three times the size of the atmospheric carbon pool. The response of this vast reservoir of C to climate change is highly uncertain. This EUsoil-C-FLUX project will focus on soil exoenzymes thermal adaptation to better understand Rsoil response to climate warming at the European scale. We will use cutting edge and interdisciplinary technology (the European Ecotron of Montpellier, isotope labeling, high throughput DNA sequencing) to provide a detailed mechanistic understanding of Rsoil responses to warming. New findings will be incorporated into the latest mechanistic C models to better predict Rsoil response to climate change, a prerequisite to fulfill a key priority of the European Union in reducing greenhouse gas emissions.

Key words : soil carbon; climate change; enzymes; microorganisms; decomposition; biogeochemistry; agricultural intensification
