Research questions
How ecological processes and human activities affect biodiversity and ecosystem functioning?
To address this question, I assemble approaches from community ecology, functional ecology and quantitative ecology. I mainly focus on cultivated ecosystems and their associated plant communities, including both cultivated and wild species (i.e. arable weeds).
My researches hinge on three particular thematics:
1) Plant invasion: Which ecological processes drive plant invasion success? How invaded species affect local plant communities?
2) Weed community ecology: How stochastic and deterministic ecological processes shape weed community assembly in arable fields? Are weeds ecological outliers?
3) Biodiversity-ecosystem functioning: How the different facet of plant diversity (eg: species richness, functional diversity, species relative density) affect ecosystem functioning? How the diversity of cultivated species can be manipulated to increase yield stability?
