Research

Current Research Topics

My research aims at identifying how to maintain biodiversity and associated ecological functions face to changes in agricultural landscapes. Therefore I focus on the links between biodiversity, management practices and landscape heterogeneity in space and time. More specifically, my approach consists in:

• Evaluating the effect of landscape heterogeneity and management practices on biodiversity
• Characterizing changes in biodiversity and its drivers (such as management practices and landscape structure) through time.
