Chercheur postdoctoral / Postdoctoral researcher

J'étudie les mécanismes de la répartition spatiale des grands herbivores, des grands carnivores et des oiseaux marins dans le but d'approfondir nos connaissances sur les interactions prédateur-proies (jeu spatial prédateur-proie, stratégie d'alimentation, stratégie de recherche des prédateurs, stratégie anti-prédatrice des proies) et d'améliorer les mesures de gestion et de conservation de la faune.

Post-doctorante – CNRS & OFB

My profile lies at the interface between scientific research and management in the field of ecology. My subjects of study mainly concern ecology of large predators (wolf, jaguar, lynx) but also of fauna linked to agriculture landscapes (Eurasian hamster, bee). The tools I use are derived from biostatistics and mainly from modelling: point process methods, individual-based modelling, spatial capture-recapture, occupancy, kernel density estimation.

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.

Mots-clés : bousiers, taons, agropastoralisme, région paléarctique, approche multi-taxons & multi-scalaire

PhD thesis subject (2024-2027): Drought effects on carbon assimilation and allocation in living tree biomass in forests

Supervisors: Jean-Marc Limousin (CNRS-CEFE) and Maxime Cailleret (INRAE-RECOVER)

Forests are a major player in the global carbon (C) cycle and at the heart of the climate change mitigation initiatives of the 2015 Paris Agreement, but models strongly disagree on the projection of this C sink under future climate change. Our current understanding of climate change effects on forest’s carbon sequestration is limited by uncertainties around the allocation of carbon among the different tree organs and the link between carbon photosynthetic assimilation and sequestration in perennial tree biomass.

The main objectives of this PhD thesis are to quantify how the C allocation in tree biomass changes among the different organs (wood, roots, leaves and reproductive organs) in response to increasing water stress and decreasing C assimilation. The research project will use both the results of five long-term rainfall manipulation experiments set in different forest ecosystems (three Mediterranean forests in Southern France, one temperate forest in North-Eastern France, and one eucalypt plantation in Brazil), and of carbon fluxes measured by eddy covariance in different forest sites within the ICOS network, to study the experimental and inter-annual effects of changing water availability. It will involve the analysis and synthesis of existing data and the collection of new data using homogenized and innovative protocols in every site, especially regarding the belowground compartment that is generally understudied in forest ecosystems.

The thesis will be articulated around three main research axes: i) improve our understanding of the link between photosynthetic C uptake and wood stem growth; ii) investigate the effects of drought on tree architecture and C allocation among the different aerial tree organs; iii) quantify belowground C allocation and its response to drought.

Current Research

I work to reveal how animals perceive and adjust to their environment, and why this matters for populations and ecosystems. My model of choice: large herbivores. Because you can (relatively) easily monitor their behaviour in natura, and they have important ecosystem effects. Some have high societal and economical values, so my research sometimes matter beyond basic science. We (as humans) are making the world's climate different. How this affects organisms in the hottest applied ecological question. I do my share to bring an answer to it

My principal area of research is Evolutionary genetics and evolutionary ecology. I have a broad expertise in evolutionary biology, genetics and ecology.

I have been working on adaptation and mutation, local adaptation, evolution of genetic systems (sex, recombination, sex chromosomes), evolution of gene duplicates, speciation, genetic conflicts, dispersal, biotic interactions (parasites, microbiota), statistics and fitness measures. I have been working with many empirical systems (vertebrates, insects, crustaceans, fungi, plants, helminths, bacteria), in the lab and in the field.

Currently, my scientific activity rests on three axes: first I do theoretical work (theoretical population genetics, statistics, and bioinformatics development). I am particularly interested currently on the evolution of gene expression (on sex chromosomes or in asexuals). Second, I work on small crustaceans Artemia and Daphnia. I’m particularly interested currently on sex-asex transitions, biotic interactions and adaptation to temperature. Third, I do experimental evolution on E. coli. I'm particularly interested on testing fitness landscape models, adaptation to different doses of antibiotics, and coevolution of species coexisting by frequency dependence.
