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.
My research focuses on interspecific interactions, particularly between plants and insects. My research projects are in the field of chemical ecology. 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, NOX) 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.
