Résumé :
Diplômé d’un doctorat en écologie, le cherche à mieux comprendre les effets qu’induisent les modifications de l’environnement à différentes échelles – du paysage à la parcelle - sur les communautés, les populations et les traits des invertébrés du sol. J’analyse les effets des changements d’occupation du sol, comme l’urbanisation, sur les communautés et les interactions. Je m’intéresse fortement aux problématiques d’agroécologie, dans les paysages ruraux mais aussi urbains.J’ai des compétences fortes dans l’intégration de la dynamique spatiale des processus, dans la détermination d’invertébrés. je fais partie d’un collectif « art-science » qui vise à sensibiliser le public à la protection des sols.

Mots-clés :

My research focuses on the developmental cycle and the ecological niche of extra-tropical forest trees, both of which are currently challenged by climate change. Identifying the key traits that allow a particular species adapting to its environment and the identifying the constraints on their genetic evolution are the key motivating forces behind my research, which lies at the interface between functional ecology and evolutionary ecology.

I have initiated pioneering work on process-based species distribution models for plants, which I use to study the evolvability of the ecological niche of tree species. My work is deeply concerned by climate change and the models I develop are also used to provide accurate forecast of trees’ distribution for the upcoming centuries.

I am using a combination of modelling (PMP, PHENOFIT), experimental work in both field and controlled conditions, as well as long term monitoring of natural populations to feed my research. I have also founded a national research group on phenology whose main achievements are an open database, a national observatory and the Citizen Science program Observatoire Des Saisons.

For master students : your applications are very welcome. Note that I am trying to mentor a maximum of 2 students per year in order to warrant my implication in your projects. I am therefore unlikely to accept applications outside a project that I have advertised myself, without fundings, or without a clear match with one of my research interests. Therefore, please read cautiously the description of my research below before getting in touch, and join a letter explaining precisely which of my projects is of highest interest to you and why. In 2022, I will supervise two Msc students (M2), with projects on island bird biogeography and vertebrate road casualties. My preference will be directed towards students with good records in ecology and biodiversity management, with a strong interest for statistical data analysis. Projects will be released between july and october 2022.

RESEARCH

My research is focused on 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.   

- Composition and diversity of insular avifaunas. I use a framework based on ecological traits to understand the relative influences of landscape structure, habitat, and exotic species in shaping the current structure of bird communities on oceanic islands. 

- Influence of landscape and habitat on the distributions of mediterranean reptiles. Relying on opportunistic data from the regional participative database Malpolon, maintained  by the Ecole Pratique des Hautes Etudes since the 1980's, I investigate the determinants of spatial patterns in reptile distributions and diversity along regional gradients of climate, land use and land abandonment.

- 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. 

COLLABORATIVE WORK WITH STAKEHOLDERS

Most of my interactions with biodiversity stakeholders are focused on data analysis to answer questions relative to the monitoring of human impacts on biodiversity.

- Influence of management practices on waterbirds. In collaboration with the natural reserve of Hyères saltpans, I investigate the impact of water management practices on the temporal dynamics of waterbird species. 

- Faunistic 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. 

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. 

- 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.

Je cherche à mieux comprendre l'écologie d'insectes associés au pastoralisme pour pouvoir optimiser les pratiques de gestion (préservation de la biodiversité et des fonctionnalités écologiques, limitation des nuisances). J'étudie, en parallèle, des espèces auxiliaires et nuisantes pour mieux comprendre les relations ambivalentes que l'Homme entretient avec les espèces sauvages au sein des écosystèmes anthropisés. La perception de ces taxons fait partie de mes questions de recherche.

Je développe enfin des méthodologies pour évaluer l'état de conservation de l'entomofaune, à l'échelle des populations et des peuplements.
