RESEARCH
My research is framed around a comparative exploration of the role of multiple environmental drivers in shaping species distributions and diversity at multiple spatial and temporal scales. Most of my research is structured on the combined use of ecoinformatics methods (statistical analysis of large data sets) and naturalist expertise to understand empirical patterns of community composition in space and time. My main active axes of research include :
- functional biogeography of seabirds in the Southern ocean. I try to explain and predict the composition of seabird assemblages with spatial models calibrated with environmental factors, trophic interactions and species traits. The project relies on a large-scale bird counts protocol from ships and statistical model of multiple data types. See the C-BIRDS project and thesis.
- understanding spatial patterns of vertebrates distributions and assemblage compositions. Relying on various opportunistic or protocoled data sources at multiple spatial scales, I investigate the determinants of spatial patterns in vertebrate distributions and assemblage composition through spatial models based on proxies of historical and contemporary processes. See for instance he MALPOLONdatabase.
- Ecoacoustics and community ecology. Several active projects focus on the relationship between bird community composition and the characteristics of soundscapes at multiple spatial and temporal scales, in order to explore the acoustic environment in which species interact and its changes with current land-use and climatic dynamics. See the ACOUCENEproject (2022 - 2025, FRB/CESAB)
COLLABORATIVE WORK
Most of my interactions with biodiversity stakeholders are focused on data analysis to answer questions relative to the monitoring of human impacts on biodiversity at a regional or landscape scale.
- Ecological data analysis. I am involved in initiatives to foster interactions between scientific and non scientific stakeholders with respect to data-based ecological monitoring and expertise. See the website of the CISSTATnetwork.
- Analysis of land use influences on common bird assemblages in southern France. I investigate the impact of land use and habitats on the temporal dynamics of local bird assemblages with opportunistic and protocoled data (collaborations with the Ligue pour la Protection des Oiseaux - PACA).
- Wildlife road casualties. I work with the Ligue pour la Protection des Oiseaux and the CEREMA to explain and predict spatial patterns in road casualites. We exploit jointly multiple sources of protocoled, non-protocoled and citizen science data to identify mortality hotspots and explanatory factors, with the final aim to inform public policies on the mitigation of traffic impact on vertebrates. See the final report of the COCPITT project (2020-2023).
- Interacting imprints of climate change and land use on biodiversity. Using multiple taxa and scales, I investigate how species' responses to historical and present land use change interact with their responses to climate change. See the LANDBIO project (2022 - 2023, OFB - french ministry of ecology)
TEACHING
Most of my teaching activity is embedded within the program of the Ecole Pratique des Hautes Etudes.
- Data analysis for ecologist : a three-weeks course dedicated to biodiversity stakeholders, framed on the practical use of statistical methods and the R software in ecological monitoring.
- Environmental law and policy : I drive a one-week course to introduce environmental public policies to scientific ecologists, involving speakers from various authorities and decision levels and practical training to improve students' written and verbal interactions with non-scientific stakeholders.
- Methods for ecological monitoring : a two-weeks course with Aurélien Besnard, mainly dedicated to master students and biodiversity stakeholders, to improve their skills and critical thinking in advanced numerical methods for ecology, including species distribution modeling, population dynamics, sampling design and analysis of diversity indices.
- Environmental changes and ecological science :I contribute to several courses on global changes and environmental monitoring. My teaching is focused on the interactions between science and society through several lenses including epistemology and governance / spatial planning.
