Thème de Recherche:

Mes travaux traitent principalement des conséquences de la sécheresse sur le fonctionnement, la vulnérabilité et les réponses fonctionnelles des arbres et des écosystèmes forestiers méditerranéens. Mon objectif est d’anticiper les effets des changements climatiques en cours sur la durabilité et le fonctionnement des forêts, et sur les mécanismes de survie ou de mortalité des arbres à l’échelle individuelle. J’aborde cette thématique principalement par une approche expérimentale in situ qui relève à la fois de l’écologie fonctionnelle, de l’écophysiologie et de l’écohydrologie. J’utilise en particulier des expériences de manipulation des précipitations qui permettent de modifier l’apport d’eau à l’échelle de l’écosystème, et que je complète par des observations à long-terme et le long de gradients climatiques régionaux.

Mes recherches visent principalement à mieux comprendre :

-          Le fonctionnement des écosystèmes forestiers soumis aux contraintes climatiques

-          La régulation des échanges gazeux d’eau et de carbone entre les arbres et l’atmosphère

-          La plasticité et la mortalité des arbres face à la sécheresse

Research interest

My research focuses on the consequences of drought on the functioning, the vulnerability and the functional responses of trees and Mediterranean forest ecosystems. I study the effects of the on-going climate changes on the sustainability and functions of forests and on the survival and mortality of trees. My approach relies simultaneously on functional ecology, plant ecophysiology and ecohydrology. I work mainly with in situ rainfall manipulation experiments in order to modify the water availability in the field, but I am also interested in using long-term observations and regional environmental gradients to understand and forecast how forests may respond to drier climate.

My main resarch interests are:

-          The water and carbon fluxes in forest ecosystems facing water limitations

-          The physiological responses of trees to water stress

-          The mechanisms leading to acclimation or mortality of trees under global-change type drought
