Research interests
Keywords : community, citizen science, indicators, biodiversity monitoring, traits, interactions, multi-taxa, management, landscape, birds, mammals, France, Europe
My scientific interests are united under the theme of conservation biology ; both its ecological basis (ex. population and community ecology) and its practical application. Since my Ph-d, I develop researches on animal and plant communities in the context of urban and agricultural environments.
I particularly interested in understanding patterns of biodiversity in response to main drivers linked to human activities (ex. land use changes), and how changes in biodiversity retroactively affect ecosystems function and human life. To this regard, I develop collaborations with social sciences for interdisciplinary researches. I mainly study birds and mammals, from local (ex. a cropped field, an urban green area) to national (France) and continent scale (Europe). I’m also interested in mechanisms explaining patterns and especially interactions between individuals within and between species.
My current projects are about ‘predictability of food and foraging behavior of birds’, ‘traits to explain animal vulnerability to pesticides’, ‘role of urban green areas and citizen science programs to conserve common birds’, ‘impact of CAP land-use changes on birds’, ‘restoration of food chain in agricultural systems by changing farming practices and restoring natural habitat around fields’, etc.
As a birder, I love doing fieldwork (bird watching, ringing, camera trapping) for my researches and my own curiosity. I am also engaged in the development of citizen science project like BirdLab (birds at feeders).
Teaching
Since 2013, I teach ecology for Engineers and Master students (urban ecology, agroecology, field ecology) in close connection with my research topics. My courses address both theoretical and finalized dimensions of ecology in relation to these issues. They are therefore relatively transversal navigating between biological and social sciences, and between scientists, stakeholders, farmers, and other professionals.
