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.

Je m’intéresse à l’écologie de la pollinisation, à l’évolution des interactions plantes-insectes et à la conservation de ces communautés. Mes travaux concernent surtout les figuiers en milieu tropical et les orchidées en milieu méditerranéen et ils portent sur la compréhension fondamentale de ces interactions et l’opérationnalité de leur conservation.

 

I am interested in pollination ecology, in the evolution of plant-insect interactions and in the conservation of these communities. My studies concern tropical figs and Mediterranean orchids and they are focused on the fundamental understanding of these interactions and using fundamental insights for operational conservation.

 

Thématique

L’environnement et l’interaction homme-nature sont en profonde mutation du fait des changements globaux actuels. Il est essentiel d’adopter une approche pluridisciplinaire dans l’évaluation des impacts de ces changements sur la biodiversité et de ses capacités d’adaptation, ainsi que d’intégrer des bases objectives et scientifiques dans les processus de décisionpour l’établissement des stratégies de conservation. Dans ce contexte, l’analyse de la dynamique des systèmes écologiques implique la compréhension des interactions entre espèces, sensibles à ces modifications environnementales. Les tropiques et la Méditerranée sont des chantiers pertinents représentant à la fois des points-chauds de biodiversité de par leur diversité spécifique et leur endémisme mais aussi des zones parmi les plus menacées au monde par différentes composantes de ces changements globaux (anthropisation, changement d’utilisation des terres et des pratiques agricoles, arrivée d’espèces envahissantes …etc).

Dans ce contexte de crise environnementale, mes problématiques de recherche concernent d’une part la compréhension de la dynamique des systèmes écologiques autour de la pollinisation des plantes par les insectes, qu’elle soit spécifique et obligatoire comme chez les figuiers ou diversifiée du mutualisme au parasitisme comme chez les orchidées. D’autre part, ces informations alimentent mes travaux en écologie de la conservation centrés sur les orchidées méditerranéennes ainsi qu’une recherche impliquée combinant le transfert vers les acteurs de la conservation par le biais de thèses Cifre et de multiples collaborations et la diffusion de l’information scientifique au sein du monde de la recherche à celui du grand public. Ma recherche trouve sa cohérence dans l’adoption une approche pluridisciplinaire en écologie de la pollinisation et l’implication sociétale en écologie de la conservation. Elle a comme fil rouge la communication, l’interaction qu’il s’agisse de relations entre plantes et insectes et de celles avec leur environnement, ou de médiation auprès des différents partenaires de la conservation, ou encore de diffusion scientifique vers différents publics.

Mon parcours de recherche a débuté sur l’écologie comportementale de la recherche et de l’exploitation des ressources alimentaires chez plusieurs espèces de fourmis, puis s’est poursuivie sur l’écologie comportementale et chimique du mutualisme de protection plantes-fourmis (voir HDR). Mon activité actuelle de recherche concerne l’écologie de pollinisation, centrée sur la comparaison entre pollinisation spécialisée (figuiers) et pollinisation diversifiée (orchidées). Elle s’étend également par une recherche impliquée en écologie de la conservation des orchidées méditerranéennes en intégrant les problématiques associées aux changements globaux et à l’évolution de la relation Homme-Nature. L’ensemble de mon activité est également associée à une activité de transfert vers les acteurs associatifs, privés et publics de la conservation, et de communication de l’information scientifique.

 

Écologie d’une pollinisation spécialisée : le cas des figuiers

Chacune des 800 espèces de figuiers est engagée dans un mutualisme de pollinisation spécifique et obligatoire avec un hyménoptère agaonide grâce à une médiation chimique. Coévolué depuis environ 80 millions d’années, ce mutualisme figuier – pollinisateur est aussi au centre d’un réseau complexe d’interactions directement ou indirectement liées à la pollinisation du figuier. En effet, deux autres acteurs principaux (hyménoptères parasites spécifiques et fourmis prédatrices opportunistes) sont aussi à ce mutualisme car ils utilisent à leur compte cette médiation chimique. Spécificité des parasites, séparation temporelle de leur moment d’intervention, détection (après apprentissage) du moment de réceptivité des figues par les fourmis prédatrices sont autant de processus structurant la communauté des hyménoptères associés aux figuiers et impliquant la médiation chimique. Ils seraient même un facteur important de la dynamique évolutive de ce mutualisme, avec par exemple certaines fourmis prédatrices qui auraient un effet positif sur ce mutualisme au point que quelques figuiers présentent des lieux de nidification (domaties). C’est par l’étude comparative de plusieurs espèces de figuiers qu’il sera possible d’établir un scénario général des relations existant entre figuiers, pollinisateurs, parasites et fourmis prédatrices.

 

Écologie d’une pollinisation diversifiée : le cas des orchidées

Les orchidées se sont diversifiées très récemment (ces dernières 10 millions d’années) dans un monde où les insectes sont déjà présents. Cette diversification est fulgurante au point qu’elles représentent aujourd’hui environ 10% des espèces à fleur et la première famille végétale en nombre d’espèce. Caractérisée par la présence de pollinies se collant sur les insectes pollinisateurs, une seule visite est suffisante pour emporter tout le pollen d’une fleur ; cette particularité favorise la multiplicité des stratégies d’attraction des pollinisateurs et explique l’importance relative des stratégies de tromperie (visuelle et sexuelle) dans cette famille. Ces stratégies se traduisent par des variations importantes et des associations particulières entre les différents caractères (odeur, couleur, morphologie, phénologie de floraison, présence de nectar) constituant le syndrome de pollinisation de ces espèces. Il existe plus de 300 espèces d’orchidées autour de la Méditerranée qui présentent une diversité de stratégies de pollinisation : elles constituent un modèle biologique idéal pour l’étude de l’écologie comportementale et chimique des relations établies avec leurs pollinisateurs.

 

Écologie de la conservation des orchidées méditerranéennes

L’écologie des orchidées (dépendance aux pollinisateurs et aux champignons symbiotiques, dépendance plus ou moins marqué à des habitats particuliers, faible aptitude à la compétition, faible densité de présence) en font des espèces souvent sensibles aux différents aspects des changements globaux, et ainsi des modèles pertinents en écologie de la conservation pour établir et évaluer les stratégies de protection. J’aborde leur conservation par une approche pluridisciplinaire en considérant différents aspects associant écologie de pollinisation et de conservation : compréhension de la phylogéographie de l’orchis bouc, analyse de la différenciation de la génétique et de la niche écologique au sein du groupe de l’ophrys mouche, étude de l’hybridation chez les orchis, influence du syndrome de pollinisation sur le taux de pollinisation chez les espèces utilisant la tromperie visuelle. Une autre approche consiste à déterminer les variations diachroniques de présence des orchidées et de leurs habitats en France méditerranéennes (LR, Corse et Paca) afin d’identifier les traits biologiques des espèces ainsi révélées sensibles. Cette approche est aussi couplée à l’étude de la variation de présence de plusieurs autres groupes d’espèces (oiseaux, amphibiens, reptiles, insectes) en région méditerranéenne (ex : Pic St-Loup), et à une analyse comparative avec la variation de présence de champignons (ectomycorhiziens et décomposeurs) également en région méditerranéenne. Enfin, la conservation des orchidées est aussi abordée sous l’angle de sa gouvernance pour une analyse critique de leur protection actuelle en France associée une proposition de leursstatuts de protections nationale et régionale.

 

Collaborations autour de la conservation

Ce thème implique une étroite collaboration avec différents acteurs associatifs, privés et publics de la conservation. Je suis ainsi membre de la SFO (Société Française d’Orchidophilie), pour laquelle je suis responsable du groupe « Relations insectes-orchidées ». Je do-dirige (avec Franck Richard) actuellement la thèse cifre d’Hélène Vogt-Schlib impliquant l’entreprise Biotope sur la conservation de la biodiversité méditerranéenne, et (avec Edmond Dounias) la thèse cifre d’Ameline Lehébel-Péron impliquant le Parc National des Cévennes sur la conservation d’une apiculture traditionnelle en tant que patrimoine naturel et culturel cévenol. Plusieurs collaborations ont également été établies avec Parc National des Cévennes, les Parcs Naturels Régionaux (des grands Causses, des monts d’Ardèche et de Corse), les Conservatoires botaniques Nationaux (de Corse, de Porquerolles, etdes Pyrénées et de Midi-Pyrénées, l’Office de l’Environnement de Corse, etl’Université Saint-Denis de la Réunion et l’Herbier de La Réunion. Expert auprès de l’ANR et de l’AERES, je suis aussi membre du conseil d’administration des écologistes de l’Euzière, des conseils scientifiques du Parc National des Cévennes, de la réserve MAB du Fango (Corse) et de l’entreprise Biotope au niveau national, et, au niveau international, membre de la SCB (Society for Conservation Biology) et expert pour l’UICN sur le ‘Mediterranean Species Programm’.

 

Diffusion de l’information scientifique

Après avoir été coorganisateur des séminaires en écologie du CEFE, mon activité de correspondant communication pour ce laboratoire (le plus gros en écologie en France) consiste à diffuser en interne les informations venant de l’extérieur (actualités scientifiques, archivage…) et à organiser la communication vers l’extérieur (site web, contact presse, événements comme les 50ans du CEFE, fête de la biodiversité …). Je favorise également les liens entre le CEFE et différentes structures impliquées dans la gestion de l’environnement (entreprise Biotope, bureau d’étude EcoMed, Ecologistes de l’Euzière). J’interviens comme enseignant ponctuel dans différents masters liés à la gestion de la biodiversité (IEGB, DAIT), je participe à l’organisation des colloques nationaux (SMPE, SFO, IUSSI) et internationaux (ISE, ISCE, ISBE) d’école thématique (écologie chimique) et d’expositions nationales (Cité des Sciences, Paris). Mon activité de recherche est également diffusée dans différentes revues régionales, nationales et internationales et lors de conférences grand public. Je suis également auteur de différents chapitres d’ouvrage et co-éditeur d’ouvrage (dont ‘Le Génie de la Nature’ et ‘Stratégie végétales’).

I study visual communication at various scales: color perception, role of coloration in communication/camouflage, informative content of signals, evolution of signal design at large evolutionary scale. At the frontier between biology and physics, I study complex optical phenomena in birds and butterflies.

RESEARCH

I am interested in coloration and visual communication at various evolutionary scales. I characterize coloration and model its perception to assess the informative content of coloration, and identify the potential receivers of the communication process. I manipulate color signals in experiments to understand how receivers use coloration to reach their decision, in relation to other sensory modalities. At a larger evolutionary scale, I run comparative analyses to understand the parts of shared ancestry and selection in driving the evolution of coloration, to ultimately determine the adaptive functions that are fulfilled by coloration. I use different approaches (correlative and experimental designs, comparative analyses) and various biological models (birds, insects, mammals, amphibians) to answer functional and evolutionary questions.

At the interface between physics and biology, my recent work aims to understand the functions and evolution of transparency in butterflies and iridescence in birds. 

I study visual communication at various scales: color perception, role of coloration in communication/camouflage, informative content of signals, evolution of signal design at large evolutionary scale. At the frontier between biology and physics, I study complex optical phenomena in birds and butterflies.

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.

Research questions

How do different facets of biodiversity affect the functioning and stability of (agro)ecosystems?

What are the roles of plant-plant interactions and functional traits in determining (agro)ecosystem functioning?

What are the drivers of the global distribution of crop species diversity ?

Can plant functional traits predict the multifunctionality of (agro)ecosystems ?

To address these questions, I assemble concepts, theories and tools from functional ecology, biogeography, agronomy and quantitative ecology. I mainly focus on cultivated ecosystems and their associated plant communities, including crop and weed species. My researches cover a range of spatio-temporal scales, from very local (e.g. plant-plant interactions) to global (e.g. global distribution of crop) and pluriannual (e.g. long-term ecosystem stability) scales.

Mes recherches portent sur les interactions interspécifiques, plus particulièrement entre plantes et insectes. Mes projets de recherche s´intègrent dans le domaine de l´écologie chimique. En favorisant une approche interdisciplinaire combinant la chimie analytique, l’écologie comportementale, la physiologie sensorielle et la biologie évolutive, j’ai étudié le rôle de la médiation chimique, particulièrement via les composés organiques volatils (COVs), dans le fonctionnement d’interactions de différents types : pollinisation, herbivorie, parasitisme et reconnaissance entre partenaires sexuels. Je travaille aussi bien dans des écosystèmes méditerranéens que tropicaux.

Favoring an interdisciplinary approach combining analytical chemistry, behavioral l ́ecology, sensory physiology and evolutionary biology, I have studied the role of chemical mediation, particularly via volatile organic compounds (VOCs), in the functioning of different types of interactions: pollination, herbivory, parasitism and recognition between sexual partners. I work in both Mediterranean and tropical ecosystems.

Thématiques français

Je consacre une partie de mes activités de recherche à la caractérisation des mécanismes évolutifs impliqués dans la nature des messagers chimiques ainsi que la détection de ces composés dans les interactions plantes-pollinisateurs. L’autre axe de mes recherches porte sur l ́impact des changements environnementaux globaux, principalement climatiques et de concentrations en polluants atmosphériques, sur la communication chimique plantes-pollinisateurs. Ces deux axes de recherches sont abordés de manière originale et intégrative car je m’intéresse aussi bien aux pressions de sélections qu’aux sources de variations proximales qui peuvent affecter l’émission des COVs, leur stabilité dans l’atmosphère que leur détection par les pollinisateurs. Une originalité forte de mon approche est que je cherche à connecter différentes disciplines afin d’étudier conjointement les deux fonctions principales des COVs émis par les plantes : défenses contre des stress (abiotiques et biotiques) et reproduction.

 

Anglais

I dedicate part of my research activities to characterizing the evolutionary mechanisms involved in the nature of chemical messengers and the detection of these compounds in plant-pollinator interactions. The other part of my research focuses on the impact of global environmental changes, mainly climatic and atmospheric pollutant concentration changes, on plant-pollinator chemical communication. These two areas of research are approached in an original and integrative way, as I am interested in both selection pressures and sources of proximal variations that can affect the emission of VOCs, their stability in the atmosphere and their detection by pollinators. A strong originality of my approach is that I attempt to connect different disciplines in order to jointly study the two main functions of VOCs emitted by plants: defense against stresses (abiotic and biotic), and reproduction.

 

Projects since 2019

POLLURISK project, MUSE (Montpellier University of Excellence): Impact of ozone POLLUtion, in the context of climate change, on plant-pollinator chemical communication: RISQue pour la résilience des services écosystémiques (2018-2022, 150 k€, PI).

ExpOz project, ANSES: Determination of ozone exposure threshold values for the resilience of plant-insect chemical communication (2019-2022, 200 k€, PI).

Partners: IMBE; LCE; LBVpam; FLP-UAE (Morocco).

The aim of these two projects was to characterize the effect of ozone pollution (O₃) on chemical communication in two types of plant-pollinator interactions: the highly specialized and obligatory interaction between the cultivated fig tree and its pollinating wasp, and the generalist interaction between lavender and the honey bee. At the end of this project, we will define tolerance thresholds for the resilience of these two interactions to a major pollutant.

IRP Chine MOST project, CNRS-INEE: "Figs and fig-wasps: a model system to investigate biotic interaction network responses to global change" (2018-2022 then 2025-2029, 100 k€, PI). Partners: XTBG ; SCBG.

The aim of the IRP was to generate basic knowledge on the impact of increasing levels of carbon dioxide (CO₂) and O₃on the stability of interaction networks and, more specifically, on the ecosystem services of pollination. For this, we used a model system, the specific mutualism between Ficus and fig insects. We studied how insects' attraction to the VOCs produced by their specific host plant was affected by high concentrations of O₃and CO₂through comparative studies conducted between three regions with high and variable tropospheric O₃ concentrations, southern France, southern Yunnan and Guangdong.

Chime2 project, PRIME 80 CNRS-INEE-IC: Biochemical constraints and ecological selection pressures in the evolution of volatile organic compounds responsible for pollinator attraction (2019-2022, 150 k€, PI) Partners: XTBG; LBVpam ; ICN.

The main objective of this project was to understand the evolutionary dynamics of floral VOC emission. Using fig trees, the aim was to understand the involvement of biochemical constraints, linked to volatile biosynthesis pathways, as well as ecological selection pressures in the establishment of VOCs responsible for attracting specialized pollinators. This approach will enable more general conclusions to be drawn on the mechanisms of co-evolution and co-adaptation at the level of chemical communication in plant-pollinator mutualistic interactions.

ASPI project, ANSES: Wild bees in the city: effects of urban pollutants on insect health and plant-pollinator interactions (2020-2024, 200 k€, WP manager). Partners: EEP; University of Mons (Belgium).

Thisproject aims to understand the effects of exposure of wild pollinators to urban pollutants (PAHs and phthalates), by combining several approaches. This will involve: (Axis 1) determining the nature and levels of contamination of wild bees living in cities (Axis 2) exploring the effects of living in low vs. highly polluted sites on pollinator health, the attractiveness of floral resources and the quality of pollen produced (Axis 3) characterizing the individual and colonial effects of exposure under controlled conditions to realistic mixtures of families of these contaminants.

COMIX project, French Embassy in China: Comparative study of the effect of O₃ concentration on the behavior of different species of fig tree pollinators (2019-2020, 13 k€, PI). Partners: XTBG; SCBG (China).

The aim of the project was to compare the sensitivity of different species of fig pollinators to different concentrations of O₃.

PolluCom project, ANR: "Effects of ozone pollution on plant-pollinator chemical communication under global warming, consequences for their interactions" (2023-2026, 702 k€, PI) Partners: LBVpam; IEES and Ecotron de Montpellier.

The aim of this project is to test the individual and combined effects of the two stress factors, O₃and temperature, on two pollination systems with different levels of specialization and with a focus on studying the mechanisms of action of O₃, using a broadly interdisciplinary approach. Both environmental stressors are expected to have an impact on plant and pollinator physiology, affecting, respectively, the emission of VOCs and their perception. These effects would emerge in particular from changes in the expression of genes involved in VOC biosynthesis and olfaction. We predict that these changes will disrupt plant-pollinator chemical communication and thus their interaction, with the generalist pollination system being more resilient than the specialist.

BeeMed project, ANSES: Resilience of bees to global changes through the prism of self-medication (2023-2025, 200 k€, P). Partners: ECOBIO; IMBE.

This project aims to define the capacity of different wild bee species to adapt to air pollution and climate change. More specifically, we will test the nutritional and self-medication resilience of bees by considering the spatiotemporal heterogeneity of environmental stressors and characterizing antioxidant resources within flowering plant pollen.

IRP Thailand SPECIFLY, CNRS-INEE project: "Characterization little-known of biodiversity: Ecology and evolution of specialized pollination by flies" (2023-2027, 10k€/year P). Partner: Chulalongkorn University.

This project aims to compare pollinator attraction strategies in two phylogenetically distant plant genera,Ceropegia (Thailand) andAristolochia (France), some of whose species have converged on the same deceptive pollination strategy. In addition to establishing a solid collaboration with the Thai team, this project opens up new prospects for understanding the factors governing the evolution of floral specialization.

Air pollution project, CAS: "Effects of air pollution on chemical communication between species - a case study of figs and fig wasps".  (2023-2026, 400 k€/ WP manager).  Partner: SCBG.

The aim of the project is to provide basic knowledge on the impact of air pollution on the stability of the interaction network between insects and plants. To this end, the effects of major pollutants (O₃, NO_X) on fig odor and the response of fig wasps to this variation in the Guangdong-Hong Kong-Macao Bay regionwill be investigated.

IRN China project, Virtual Institute on Biodiversity, CAS-CNRS (2024-2028, 15k€/year PI). Partners:  researchers from 25 different units.

The virtual institute comprises a steering committee and around 15 pairs of principal investigators from CAS and CNRS institutes. The main objective of this IRN is to strengthen and develop Franco-Chinese collaboration on various aspects of biodiversity research through a network of scientists from both countries, and to set up an educational program for young scientists.

Blastosome project, Exposome-CNRS: A novel component of the fig exposome: its pollinator, the blastophage (2025-2026, 25k€ PI). Partners CRBM Montpellier (CNRS-INSB).

Our project is to study the disruptive effect of ozone pollution and rising temperatures on fig tree-blastophaga-Wolbachia-nematode interactions. We will draw on the complementary skills of a CNRS Biology team specializing in Wolbachia, nematodes and insect reproduction, and a CNRS Ecology & Environment team specializing in the chemical ecology and evolutionary biology of the Ficus-pollinator system.

I study the evolution of adaptive diversity, using colour patterns in butterflies as a model. In my group, we integrate many different approaches, including ecology, genetics, and modelling, to try and untangle how multiple factors influence the evolution and maintenance of diversity and polymorphisms.

I am a PhD candidate studying scavenger communities and their responses to anthropic pressures. To do so I focus on different levels of organisation. More precisely, I study how climate change modified the repartition of the living prey and feeding events of a facultative scavenger, spotted hyaena (Crocuta crocuta); how increased abundance of elephant carrion may have impacted predator prey coupling of the population dynamics of the spotted hyaena and its usual linving preys ; and how land-use and forest loss impact the structure of scavenger communities and scavenging process.

Thèmes de recherche

(English follows)

Mes travaux cherchent à parvenir à une meilleure compréhension du déterminisme de la diversité végétale aux différentes échelles spatiales et temporelles, sa réponse aux changements futurs, et son rôle dans le fonctionnement des écosystèmes forestiers. En particulier, je cherche donc à comprendre et prédire comment la biodiversité des écosystèmes forestiers s’organise selon différentes échelles spatiales, comment elle sera modifiée par les changements globaux, et quelles en seront les conséquences sur le fonctionnement de ces écosystèmes. Pour ce faire j’essaie de développer une approche intégratrice basée sur les processus. Mes travaux se focalisent principalement sur les espèces d'arbres et arbustes. Pour mener à bien ces objectifs, j’utilise aussi bien des résultats issus d’expérimentation, d’observations le long de gradients écologiques in situ, et de modélisation.
