Plant-plant interactions

Plant Community Ecology

Our research focuses on the mechanisms of plant interactions and on their consequences for biodiversity, with emphasis on positive (facilitative) interactions. We use observational and experimental methods and apply trait-based approaches to look into competition and facilitation processes and to investigate their consequences for species coexistence and community assembly. We are particularly interested in niche-based approaches to plant interactions and the potential evolutionary consequences of facilitation for the interacting species. We study plant interactions in alpine, semi-arid and agricultural ecosystems.
