THÈMES DE RECHERCHE

Écologie des sols

Les flux d’énergie et le cyclage d’éléments nutritifs sont deux aspects fondamentaux du fonctionnement des écosystèmes terrestres. Le sol représente une "zone chaude" d'activités biologiques où se couple les métabolismes autotrophes et hétérotrophes. Dans mon laboratoire, on s’intéresse principalement aux cycles du carbone et de l'azote, à la nutrition minérale et organique des végétaux, à l'activité et la diversité des communautés microbiennes du sol, à la rhizosphère, aux mycorhizes et à certains groupes fauniques du sol. Ces divers volets de recherche cadrent dans un plus large contexte qui est de décrire les effets des perturbations naturelles et anthropiques sur la succession des écosystèmes forestiers. Ces travaux visent donc à faire évoluer les concepts et les modèles théoriques de la succession écologique qui pourraient éventuellement nous aider à mieux gérer nos forêts.

Ce programme de recherche consiste en un travail d'équipe avec les étudiants gradués de l’université de Sherbrooke, misant sur la collaboration de partenaires québécois et canadiens des secteurs publics et privés.

Je suis aussi un membre du Centre de recherche en écologie terrestre de l'Université Sherbrooke  et membre associé au Centre de recherche interinstitutionnel en amélioration végétale (SÈVE)
