Principaux thèmes de recherche:
Mes travaux se situent à l'interface entre le fonctionnement des espèces et ceui des écosystèmes. Plus précisement, je m'intéresse à la recherche des compromis auxquels font face les végétaux durant leur croissance et les conséquences de ces compromis pendant et après la sénescence des plantes.
Les principaux objectifs de mon travail sont :
• Caractériser la réponse des composantes de performance des espèces (croissance, reproduction) et des stratégies écologiques des espèces aux gradients de facteurs du milieu (abandon, intensification cultural, pâturage, fertilisation, pollution de sol par les métaux lourds, gradient d'intensité de gestion des cultures pérennes tels que les vignes ou les oliveraies).
• Les relations entre les traits fonctionnels et le fonctionnement des écosystèmes (décomposabilité des litières, digestibilité de biomasse) mais aussi avec la pollinisation et les régulations biotiques.
• Caractériser les réponses des communautés des adventices (richesse spécifique, abondance, diversité fonctionnelle) aux différents systèmes de culture innovants. Notre modèle d’étude est l’enherbement permanent des vignes.
Dans ce contexte, les principales questions abordées se répartissent sur les 3 axes suivants :
-Quelles sont les stratégies adaptatives des espèces qui décrivent le fonctionnement des végétaux le long des gradients de perturbation et de niveaux de ressources ?
-Quelles sont les conséquences des pratiques de gestions sur la structure fonctionnelle des communautés à différentes échelles spatiote-mporelles ?
-Quels sont liens entre diversité fonctionnelle communautés végétales-pollinisateurs-herbivores et organismes du sol ?
Research interests:
My research is focused on the analysis of the ecological consequences on the variability of species functioning via the use of plant functional traits.
More precisely the main objectives of my research are:
-Characterize species responses (growth, performance) and species ecological strategies across environmental gradients (cultural abandon cultural intensification, grazing, fertilization, concentration on heavy metals on soil)
-Description of the links between species functional traits and ecosystem functioning (litter decomposition, biomass digestibility) in a context of land use change. Especially, I am interested to determine the links between species traits and their palatability and digestibility.
-Identify the above-belowground linkages in response to herbivory: test the after-life hypothesis in different contexts and with different herbivores (mammals, mollusks, insects). Identify is the same traits protecting leaves against herbivory are affecting their rate of decomposition.
-Characterize communities responses to different innovate agricultural systems and especially in vineyards.
