Thématique de recherche

 

alt

 

Je développe un travail d’écologie évolutive qui vise à analyser les traits d'histoire de vie chez les plantes (systèmes de reproduction, traits floraux, dispersion). L’accent est mis l'accent sur l'importance de la dynamique écologique (dynamique des métapopulations, démographie) comme un processus de sélection dans l'évolution contemporaine. Mon approche combine (1) Analyse des patrons d’adaptation et méthodes d’inférence des traits d’histoires de vie dans les métapopulations de plantes, en milieu naturel (2) élaboration de modèles formels en écologie évolutive (3) expérimentations et tests d’hypothèses en conditions contrôlées.
