Recherche

Ma recherche porte sur les interactions entre les espèces (interactions biotiques) et la dynamique des limites de la répartition des espèces. Une grande partie de mes recherches est basée sur le terrain; je mène des expériences à grande et petite échelle dans des environnements naturels pour tester et affiner des idées théoriques en écologie et en évolution qui ont une pertinence pratique pour la conservation. Je m'intéresse particulièrement à l'adaptation des populations à la limite des aires de répartition, aux interactions entre les fleurs et leurs visiteurs et au rôle que les interactions biotiques jouent dans la répartition géographique des espèces.
