Mobility project

Assessing the efFEct of global change driVERs on multifunctionality in global drylands

The project aims to assess the impact of global change drivers (climate, land use) on multifunctionality (i.e. the ability of an ecosystem to sustain multiple functions simultaneously) in global drylands. Dryland ecosystems are highly vulnerable to desertification and support 38% of the total human population. We will use a trait-based approach with a global database from 236 sites from all continents.  We will (i) quantify the effect of global change on plant and soil functional diversity; (ii) assess how changes in dryland functional diversity impact multifunctionality; (iii) develop process-oriented models to forecast the effect of global change in global drylands.

Biography & research interests

I’m an ecologist interested in the study of biodiversity working at the INRA. My main research area is the study of biotic interactions within and across trophic levels. One of my leading achievements today has been to produce important insights on how biotic interactions (plant-plant and plant-animal interactions) determine the structure of plant communities, species coexistence and feedback on ecosystem functioning. I’m using functional traits as a tool to upscale individual response to biotic interactions at the community and ecosystem levels. I use different approaches including descriptive data on community trait, models and experimentations.

I’m currently working in the AGRIPOP team (USC 1339, CNRS-INRA, CEBC). I’m focusing on how land use intensification at local and regional scale impact functional diversity within plant and animal communities and how these changes feedback on ecosystem functioning and agricultural systems. Other significant working experiences included: (i) a postdoctoral fellowship in New Zealand (supervisor Philip Hulme, Lincoln university, Canterbury) on biological invasion; (ii) a postdoctoral fellowship in Clermont-Ferrand (supervisor Jean-François Soussana, INRA, UREP) on the relationship between plant functional diversity and grassland functioning. I did my PhD at the LECA (University of Grenoble 1) on subalpine grasslands under the supervision of Sandra Lavorel.
