FORMATION

• B.Sc. (Botany), McGill University, Canada (2002)

THÈMES DE RECHERCHE

Nous étudions les traits fonctionnels des plantes afin de mieux comprendre et de prédire la distribution des espèces végétales le long de gradients environnementaux. L’emphase est sur la fertilité des sols et les traits fonctionnels reliés à l’acquisition et l’utilisation des éléments nutritifs. En particulier, nous étudions les interactions entre plantes et sols et les conséquences qu’ont ces interactions sur la biodiversité végétale et le fonctionnement des écosystèmes terrestres. Les connaissances obtenues s’appliquent entre autres au niveau de la restauration d’écosystèmes dégradés.

Le programme de recherche porte sur les interactions entre plantes et les propriétés abiotiques et biotiques des sols afin de mieux comprendre:

1. l'influence de la fertilité des sols sur la biodiversité végétale;
2. le développement d'écosystèmes terrestres, incluant la succession primaire;
3. les traits fonctionnels des plantes expliquant la distribution d'espèces le long de gradients édaphiques.

La recherche permet d'améliorer la gestion des écosystèmes naturels et d'optimiser les stratégies de restauration écologique d'écosystèmes dégradés.

Champs d'expertise

• Écologie végétale
• Écologie fonctionelle
• Interactions plante-sol

DISTINCTIONS REÇUES

• Décembre 2016 - Étienne Laliberté remporte The New Phytologist Tansley Medal : The New Phytologist Tansley Medal is awarded annually in recognition of an outstanding contribution to research in plant science by an individual in the early stages of their career (including students and any researcher with up to five years’ experience since gaining/defending their PhD). The winner recives a prize of £2000 (GBP) and authors a short review, published in New Phytologist, accompanied by an Editorial. The winner of the 2016 Tansley Medal for excellence in plant science is Étienne Laliberté, of the University of Montreal, Canada.
