Description du projet
Contribution du microbiote karstique au cycle mondial du carbone
Les écosystèmes karstiques sont considérés comme des puits rapides de méthane atmosphérique (CH4) ou des sources alternatives de CO2. Des recherches avancées laissent entendre que l’action microbienne peut avoir un rôle central dans l’absorption, la fixation ou la production de CO2 et de CH4, mais également déterminer les changements des principaux bilans de gaz à effet de serre dans les écosystèmes karstiques. Le projet MIFLUKE, financé par l’UE, entend créer un modèle biogéochimique des processus microbiens afin d’éclaircir le rôle du microbiote karstique dans les principaux gaz à effet de serre (CO2 et CH4). Les résultats du projet feront la lumière sur la contribution exacte des écosystèmes karstiques au cycle mondial du carbone, répondant ainsi à la priorité de l’UE concernant l’action climatique, mise en place par le programme Horizon 2020.
Objectif
The assessment of carbon cycle in the Earth-climate system is one the highest challenge in science nowadays. It still remains some key knowledge gaps and uncertainties concerning the budgets of greenhouse gases (GHGs) at ecosystem scale and the key role of microbial communities. Karst ecosystems cover up to 25 % of the land surface and they are acting as rapid CH4 sink and as alternately CO2 source or sink. Pioneer results point to microbial action must be playing a crucial role in CO2 and CH4 uptake, fixation or production and maybe determining the strong variations of these major GHGs in karst ecosystems.
MIFLUKE will elucidate, for the first time, the role of karst microbiota in the main GHGs -CO2 and CH4- content and fluxes in underground vadose atmospheres, as a key challenge to clarify the accurate effective contribution of karst ecosystems to the global carbon cycle. By applying an innovative and multidisciplinary combination of a broad suite of advanced tools and cutting-edge technologies from very different research areas -GHGs flux monitoring, isotopic geochemical tracing, biogeochemistry, metagenomics, etc.- a biogeochemical model of microbial processes will be developed. This project will combine the expertise of a multidisciplinary group of leading researchers on ecosystem functioning, GHGs and biogeochemistry modelling, with the extraordinary resources including analytical facilities and training support in PLECO (Univ. Antwerp, Belgium).
The proposal represents an exceptional opportunity the candidate to acquire the essential skills that will open new career avenues and will convert her into a highly competitive European researcher. In turn, the fellow will bring specific expertise to PLECO that will open a new and promising research field.
This proposal directly addresses the cross-cutting priority of climate action established by H2020 Work Programme and will reinforce the already large European competitiveness in GHGs research and management.
