Ecosystems generate services on which humans depend directly or indirectly, such as biomass production, climate regulation, pollination, and biotic control. One challenge is to understand and predict how biodiversity changes will affect the delivery of these ecosystem services. I am interested in unraveling the dynamics of the relationships between biodiversity and ecosystem functioning. I also study synergies and trade-offs between multiple ecosystem services, e.g. crop production, crop pollination and biodiversity, in heterogeneous landscapes. This framework is applied to find solutions to our current agricultural system so that food production, biodiversity and biodiversity-based ecosystem services can be simultaneously promoted.
