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 focuses on the geographic distribution of animal behaviours and traits. By combining ecoinformatics approaches with naturalist expertise, my projects explore an interface between functional ecology, biogeography and behavioural ecology

Main active projects :  

- SONGMAP - acoustic biogeography of the world's passerines. Vocalizations ensure informational connectivity among the individuals of a soniferous species assemblages. In this project, we explore the global diversity of strategies for information coding in Passeriform birds and its community-level consequences. See also the ACOUCENEproject on acoustic connectivity in bird communities (2022 - 2025, FRB/CESAB)

- C-BIRDS - functional biogeography of seabirds in the Southern ocean. Antarctic seabirds exhibit a fascinating range of behavioral and functional strategies to cope with extreme climates and the distribution of resources over the ocean. We adopt a spatial modeling framework to understand the abiotic and biotic factors organizing these strategies across the austral ocean. See the C-BIRDS project and thesis.

- COCPITT - assessing the spatial impacts of the roadkill risk on wildlife. We test the potential of citizen-generated opportunistic wildlife records to assist spatial planning policies through regional-scale biodiversity models, currently using the roadkill risk as a study model with options of extensions to other biodiversity monitoring questions. See the results of the initial COCPITTproject within the ITTECOP program

COLLABORATIONS

I am involved in a range of research projects on various aspects of population, community and ecosystem ecology with both basic and applied outcomes. See for instance : 

- QWERTY project : how fire dynamics impact the distribution of functional strategies in Mediterranean forests

- ECOPHY-ANTAVIA : population ecology of antarctic seabirds

- CISSTAT network : fostering interactions between academic and non scientific stakeholders on data-based ecological monitoring and expertise

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, 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 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.

HDR : Impact des changements globaux sur la biodiversité et le fonctionnement des écosystèmes forestiers - soutenue le 11/2/2021
Lien : HDR Xavier Morin

 

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.

Chercheur en biologie évolutive au CEFE depuis 2000, je m'intéresse à l'évolution des stratégies de reproduction et de laconsanguinité chez les animaux. J'étudie lasélection sexuelle, l'allofécondation, et l'isolement reproducteur, qui sont des stratégies évolutives pour augmenter la valeur sélective des descendants dans différents contextes. Récemment j'ai étendu mes recherches pour comprendre comment l'évolution destraits d'histoire de vie affecte ladiversité et la structure des communautés, à travers lesinvasions biologiques et les mécanismes decoexistence d'espèces dans des communautés spatialement structurées.

J'utilise surtout trois techniques : lagénétique quantitative, les suivis de terrain à long terme, et les marqueurs moléculaires. De temps en temps un peu demodélisation. Mes animaux favoris sont les escargots d'eau douce, de fascinantes petites bêtes avec une étonnante diversité de modes de reproduction. Mais j'ai aussi travaillé avec des bivalves, des mouches, des amphibiens, des plantes (il n'y a pas que les oiseaux et les drosophiles dans la vie !). Je monte des expériences de génétique quantitative à grande échelle dans notre animalerie à mollusques. Je fais aussi un suivi régulier des mollusques invasifs et résidents des communautés aquatiques antillaises (Guadeloupe et Martinique). Ci-dessous plus de détails sur les 2 axes de recherche.

Axe 1: Evolution des stratégies de reproduction et consanguinité

Questions : Tout individu est le produit d'un événement de reproduction. Ces événements s'organisent en réseaux reproductifsou pédigrées de structure souvent non aléatoire. Ainsi les pédigrées peuvent être en partie découpés en parties disjointes (isolement reproductif), le nombre de descendants peut varier beaucoup d'un individu à l'autre (variance du succès reproducteur), des croisements peuvent se produire entre apparentés (consanguinité). Je recherche en quoi la structure des pédigrées affecte la distribution de la valeur sélective dans une population, et interagit avec l'évolution des stratégies de reproduction. Ces dernières sont des traits qui donnent aux individus l'opportunité de modifier la forme du pédigrée de sorte à augmenter la valeur sélective de leurs descendants : évitement des croisements interspécifiques ou consanguins, choix du partenaire.   Modèles Biologiques : J'ai étudié les conséquences de la consanguinitéet de la reproduction croisée sur la valeur sélective, depuis la dépression de consanguinité jusqu'à la dépression hybride, chez plusieurs organismes comme les mollusques bivalves(clams Spisula ovalis; moules Mytilus spp.) les crapauds(Pelodytes punctatus), et l'escargot d'eau doucePhysa acuta. J'ai étudié l'isolement reproductif chez Mytilus, la sélection sexuelle et le choix du partenaire chez les mouches pédonculées(Cyrtodiopsis dalmanni), et les stratégies d'auto ou d'allofécondation chez les escargots d'eau douce(Bulinus truncatus, Physa acuta...) Actuellement je travaille surtout sur l'évolution de l'allocation au sexe et du système de reproduction chez Physa acuta.   Quelques résultats remarquables : - Une série de modèles montrant comment la consanguinité au sens large (autofécondation, réductions de taille ou subdivision des populations) crée des corrélations positives entre l'hétérozygotie moléculaire (microsatellites, allozymes) et la valeur sélective. Ils incluent des méthodes statistiques pour analyser ces corrélations, ainsi qu'une étude de cas sur le bivalve Spisula ovalis. - Plusieurs études de génétique quantitative sur l'effet de la variation environnementale sur les systèmes de reproduction. Tout est une affaire de norme de réaction: l'interaction entre stress environnemental et qualité génétique, qui détermine le développement des ornements sexuels des mâles de mouches pédonculées; la perte, induite par la chaleur, de l'appareil copulateur mâle chez l'escargot Bulinus truncatus; le comportement d'attente de Physa acutaqui repousse sa première ponte (plutôt que de s'autoféconder) quand elle ne trouve pas de partenaire. - Une méthode pour estimer les taux d'autofécondationavec des données de génotypes multilocus dans une population, sans utiliser Fis, et donc sans les biais dûs aux allèles nuls et autres genotypages erronés. Disponible en freeware. - La découverte pour la première fois chez les animaux d'un ADN mitochondrial porteur de stérilité mâle, capable de transformer un hermaphrodite en femelle. Ces femelles coexistent avec des hermaphrodites normaux (gynodioécie) - un phénomène connu jusqu'ici seulement chez les plantes. Nous l'avons trouvé chez l'escargot Physa acuta. Les mitogénomes porteurs de stérilité mâle sont extrêmement divergents des mitogénomes normaux dans la même espèce, suggérant une évolution de type course-aux-armements. L'ADN mitochondrial, transmis uniquement par la mère, a évolutivement intérêt à privilégier la voie femelle au détriment de la voie mâle chez un hermaphrodite, aboutissant à un conflit avec les gènes nucléaires (transmis par les deux sexes). Projets en cours: L'essentiel de mes projets en cours sont sur Physa acutaoù j'étudie l'allocation au sexe, le comportement reproducteuret la sélection sexuelle. J'ai notamment mis en place des protocoles d'évolution expérimentale de l'allocation au sexe (qu'est-ce que cela fait d'arrêter la sélection sur la fonction femelle, ou sur la fonction mâle), de la gynodioécie (évolution de la stérilité mâle). En collaboration avec J. Tonnabel (ISEM), je m'intéresse, après avoir exploré la sélection sexuelle chez les hermaphrodites animaux, à la sélection sexuelle chez les plantes. Enfin, je m'intéresse à la nature de la dépression de consanguinité et au rôle potentiel de l'épigénétique dans son maintien.

Spisula ovalis,espèce où j'ai detecté une corrélation entre hétérozygotie et valeur sélective due à la consanguinité; ceci contredit l'idée que les invertébrés marins à larves dispersant dans le plancton ont des populations parfaitement panmictiques         Bulinus truncatus,individu avec son phallus sorti. Dans cette espèce le développement du phallus est supprimé chez certains individus. La probabilité de perte du phallus augmente avec la température, suivant une norme de réaction propre à chaque génotype Les pédoncules oculaires allongés de ce mâle de mouche pédonculée (Cyrtodiopsis dalmanni) sont un des traits que les femelles utilisent pour choisir les mâles qui donneront de bons gènes aux descendants. Dans les environnements très stressants, les contrastes entre mâles pour ce trait sont renforcés             RMES, pour Robust Multilocus Estimates of Selfing, logiciel libre sous Windows pour estimer sans biais des taux d'autofécondation avec des données de génétique des populations.

Axe 2 : Traits d'histoires de vie, invasions biologiques et communautés

Questions :   Comprendrel'assemblage et la dynamique des communautés d'espèces est un objectif ancien en écologie. La plupart des modèles supposent que les espèces ont des traits fixes, donc que les événements écologiques sont instantanés à l'échelle du temps évolutif. Cependant deux processus évolutifs au moins contribuent à la construction des communautés : la spéciation et l'évolution des traits, qui modifie les interactions entre espèces. Lesinvasions biologiques sont un des processus d'assemblage des communautés. Je cherche à savoir (i)comment les traits évoluent pendant et après l'invasion d'une espèce (ii) si l'invasion est dépendante de certains traits. J'ai aussi travaillé sur les modèles destabilité  évolutive des communautés. Parmi des communautés écologiquement stables, seules quelques-unes sont évolutivement stables (i.e. les traits des espèces ne sont pas sélectionnés pour augmenter ou diminuer). Nous utilisons pour traiter cette question des modèles de trade-off entre traits (compétition et colonisation). Ebnfin je m'intéresse çà la question de l'inférence des mécanismes de coexistence ou d'interactions entre espèce (compétition, niche écologique) dans des métacommunautés : comment à partir de jeux de données observés comprendre les processus qui régissent les distributions (où une espèce est-elle trouvée), les corrélations (quelles espèces trouve-ton ensemble ou pas), les turnovers (comment changent les communautés dans le temps).   Modèles biologiques:   J'ai étudié deux modèles d'étude principaux : lesmouches des fruits (Tephritidae), une série de trois espèces invasives plus une endémique à l'île de La Réunion; et lesescargots d'eau douce aux antilles françaises, à travers l'invasion des rivières de Martinique par des escargots ThiaridésMelanoides tuberculata etTarebia granifera.etla dynamique desméta-communautés de mollusques d'eau douce, à la fois indigènes et introduits, dans un système de rivières et de mares en Guadeloupe.   Quelques résultats remarquables:  - En combinant phylogéographie moléculaire, suivis de terrain, et génétique quantitative, nous avons analysé la diversité des traits d'histoire de vie dans les populations introduites deMelanoides tuberculata. Ce jeu de données constituela démonstration la plus spectaculaire que les populations invasives peuvent accumuler de la diversité génétique pour des traits écologiquement importants grâce à des introductions répétées. Cette diversité est encore augmentée par la production de nouveaux phénotypes par des croisements entre souches introduites. - les modèles spatiaux d'invasion sont classiquement fondés sur des équations de diffusion en paysage continu. Mais beaucoup d'invasions ont lieu dans des habitats fragmentés (par ex. eaux douces).Nous avons mis au point un modèle d'invasion en métapopulation et estimé ainsi des paramètres de colonisation pour un invasion récente : celle de l'escargot Tarebia graniferaen Martinique. Grâce au modèle nous pouvons re-simuler l'invasion, en changeant certains paramètres (densité et taille des sites favorables, point d'introduction etc.) pour comprendre l'effet des caractéristiques du paysage et de la stochasticité sur la dynamique d'invasion. Cette démarche a au fil des années été développée pour estimer simultanément les paramètres de colonisation et d'extinction de toutes les espèces d'une guilde (celle des escargots d'eau douce des mares de Guadeloupe), en prenant en compte leurs différentes "niches" (le fait que les milieux favorables à l'une ne sont pas ceux qui sont favorables à l'autre). Nous arrivons ainsi, pour la première fois, à évaluer la diversité des niches dans une métacommunauté.

La mare de Saint-Félix en Guadeloupe est l'un des200 sites où nous suivons annuellement les communautés de mollusques d'eau douce Melanoides tuberculata.Cette collection de coquilles montre l'étonnante diversité morphologique des souches invasives de cette espèce. Ces souches diffèrent aussi pour des traits d'histoire de vie comme la fécondité ou la taille des juvéniles. [couverture d'un numéro de Current Biol., 2008]               4 espèces de mouche des fruits (Tephritidae), une endémique (haut à gauche) et trois envahisseuses successivement introduites dans l'île de la Réunion (Océan Indien) . L'aptitude à la compétition augmente à chaque nouvel envahisseur.

On a longtemps cherché des traits typiques des espèces invasives. Nous avons émis et validé l'hypothèse quele succès invasif dépend des valeurs de trait relatives d'une espèce par rapport aux espèces locales apparentées avec lesquelles elle est en compétition. Avec des expériences en laboratoire nous montrons que dans une série d'espèces deTephritidae ayant envahi successivement l'île de La Réunion, les plus récentes sont compétitivement dominantes sur les anciennes Contrairement aux hypothèses classiques, les meilleurs envahisseurs ont des taux de croissance intrinsèque (r) relativement faibles. Projets en cours:  Je continue à travailler sur l'analyse statistique de données de terrain (Thiaridés de Martinique, mollusques d'eau douce de Guadeloupe) pour (i) reconstituer les interactions entre espèces (compétition notamment) à partir des dynamiques temporelles d'invasion ou de turnover dans des métacommunautés (ii) comprendre les mécanismes decoexistence des espèces dans les méta-communautés de mollusques de Guadeloupe, et en particulier l'effet de la diversité des traits d'histoire de vie et des systèmes de reproduction sur cette coexistence.

Current Biology, 32(10), 2325-2333.e6 doi : 10.1016/j.cub.2022.04.014 [It is intellectually frustrating when some theory seems to apply only to one group for no particular reason. This was the case of cytonuclear conflict theory: nuclear genes are inherited from both parents, while cytoplasmic genes (such as mitochondrial genes) are usually propagated only through eggs. The two types of genes are therefore exposed to conflicts over how much energy a hermaphrodite should spend producing female versus male gametes. We have lots of examples in plants, where mitochondria capable of suppressing pollen production evolve, triggering counter-adaptation of nuclear genes restoring pollen production. But surprisingly not a single convincing example in animals. Well, until we discovered the first one in my favourite snail, Physa acuta. The story started with an amazingly divergent mtDNA, so much so that it took us lots of double-checks to ascertain it was in the same species as the standard P. acuta mtDNA. Indeed it was, but the snails carrying it turned out to be incapable of inseminating standard P acuta, though they happily received their sperm. They had lost the male function, with practically zero sperm production and no male behavior. Among snails, P. acuta is now definitely my hero: It is the first example of cytoplasmic male sterility in animals, and it has the highest degree of molecular divergence ever observed between two mitogenomes within a eukaryotic species. This coincidence suggests that accelerated evolution has played a role in a potential evolutionary arms-race between mitochondrial and nuclear genes.]

Current Biology, 27 : 237-242 [Some ideas in biology have been repeated over and over with surprisingly little evidence. This is the case of the opinion that selfing species are evolutionary dead-ends as they cannot respond to new selection pressures. We test this idea directly by comparing the reponse to artificial selection for a morphological trait in snail populations under either outcrossing and selfing, and with or without previous experience of self-fertilization. Selfing initially speeds up the response to selection, but then slows it down after a few generations while outcrossing lines continue to respond. This effect, consistent with the dead-end hypothesis, not only reflects an exhaustion of genetic variation but also an increase in nonheritable phenotypic variance under selfing. ]

We review lots of empirical examples of these effects and come up with the idea that, regardless of the type of interaction, extreme impacts arise because of lack of coevolution combined with an invasion filter : non-coevolved species, exotic vs resident, tend to have more extreme interactions on average, in favor of either one or the other, but only when they are favorable to exotics do the latter successfully invade. Consequently, eco-evolutionary immaturity of resident food webs, due to historical isolation, recent eutrophication, lack of top-predators or of important feeding types, or anything that has kept diversity relatively low, make them prone to experience large (and irreversible) impacts of potential invaders. We discuss the potential lessons for remediation / conervation policies]

In this theoretical study, we question this view and show that, under three classical models of species coexistence, diversification is easier when some diversity is already present than when there is only one species.

In addition we did a metanalysis showing that evidence for size-assortative mating tends to exist only in reciprocally-copulating hermaphrodites in which mates play symmetrical roles, and therefore may both be choosy]

Molecular Ecology, 20: 1877-1887 [In this study of heterozygosity-fitness correlations (HFC) in frogs, HFC arises from the mixing of populations with different average heterozygosity and larval growth, rather than from differences among individuals within populations. Therefore, covariation in larval traits and heterozygosity is due to fixation load rather than to within-population polymorphism]

Evolution, 65(5) : 1233-1253 [A big collaborative study to measure selfing rates, waiting times (=reproductive delays when an individual is forced to self-fertilize), and inbreeding depression in a dozen new pulmonate species, and to collect similar published data on other animals. We show that species are either highly outcrossing, with significant waiting time and large inbreeding depression or highly inbred, with no significant waiting time nor inbreeding depression. This generalizes our previous results on Physa acuta (P76, P59, P33, P30) and mirrors previous results obtained in plants, with the difference that mixed-mating systems seem absent]

Molecular Ecology 20: 2044-2072 PDF Download supporting info[This is more than a cautionary note on genome scans ! Very long but worth the effort, it will change the way you think about molecular approaches to adaptation..Population geneticists often use genome scans, looking for molecular markers with exceptional differenciation between two habitats, to map genes with major effects on adaptation to habitat. We show that genes promoting pre or postmating isolation, irrespective of habitat, naturally become coupled with habitat specialization genes, so that clines in allele frequencies come to coincide with habitat boundaries. The abundance of isolation genes in genomes, and their efficiency at maintaining linkage disequilibrium with nearby neutral markers, make it likely that genome scans actually map them rather than habitat adaptation genes. We provide some simulations and convincing examples from the literature to illustrate this process]

[With the advent of microsatellites, years after the golden age of allozymes, we are witnessing a new bloom of studies on heterozygosity-fitness correlations (HFC). Yet lessons from the past (especially from old theory) have been ignored, and recent HFC studies often reveal misunderstandings that sound all too familiar to old - well, let's say middle-aged- population geneticists like myself. Do you want a theoretical summary as well as a practical guide on HFC ? Do you simply want the truth about HFC ? Read this paper...]
