    J'étudie le rôle de la médiation chimique dans le fonctionnement de différents types d´interactions plantes-arthropodes. J'ai pour objectif de caractériser l´impact de l’augmentation de polluants atmosphériques sur la rencontre entre espèces dans les interactions plantes-insectes et donc sur la résilience de ces interactions. J'étudie également les mécanismes évolutifs expliquant la nature des signaux chimiques ainsi que la détection de ces signaux dans les interactions plantes-pollinisateurs.

     

    I study the role of chemical mediation in the functioning of different types of plant-arthropod interactions. I aim at characterising the impact of increasing concentrations of atmospheric pollutants on the encounter between species in plant-insect interactions and hence on the resilience of these interactions. I also investigate the evolutionary processes explaining the nature of the chemical signals and how they are detected in plant-insect interactions.

    Title:Pest Management Across Scales: Insight From Mountainous Tropical Agroscapes.

    Context: the tropical Andes is a world full of gradients that occur at several spatial scales. At the crop scale, a mosaic of spatial and temporal microclimates exists due to the high diversity of crop plants and the diel temperature changes. At the landscape scale, the diversities of land-management and land-use produce a gradient of landscape complexity. Finally, at the human-community scale, there is a wide diversity and combinations of human cultures related to historical contingency. This combination of abiotic-, biotic- and human-related gradients makes the tropical Andes an attractive playground for ecologists who are interested in understanding the effects and interactions of these drivers on agroecosystems.

    Goal: I aim at identifying the drivers of pest control across these three spatial scales in order to propose practical solutions for the local farmer communities. Each chapter focuses on a specific scale, with its particular set of drivers of pest control.

    Chapter 1: At the crop scale, temperatures vary tremendously both spatially and temporally, which impacts the development and emergence of pests. To cope with this highly fluctuating environment, we expect species to have developed a variety of developmental and phenological adaptations. We integrated, for the first time, slow-fast thermal strategies into a mechanistic predictive framework. The model calibrated with the observed individual thermal strategies showed a high accuracy in phenological predictions. This model can therefore be used to accurately predict the emergence of pests in the Andean context. Read more...

    Chapter 2: At the landscape scale, we aim at identifying potential trade-offs and synergies between landscape characteristics and agrochemical use on insect diversity and functions. We are especially interested in the potentially opposite effect of these two drivers on arthropod pests and pollinators, which both ultimately influence crop yield.

    Chapter 3: At the human-community scale, we aim at assessing whether agrochemical resellers are responsible for pesticide overuse in the Andes. Reseller knowledge on common pests and the quality of their recommendations will be evaluated.

    Chapter 4: At the human-community and landscape scale, we aim at understanding how the perception of ecosystem services and the landscape can be influenced by the traditional knowledge of indigenous and non-indigenous farmers.

    Altogether, these different chapters will provide new insights in several areas of natural and human sciences, along with practical solutions to be included into an integrated pest management program.

    Sujet de thèse :

    Qui coexiste avec qui ? Qui est en compétition avec qui ? Qui coopère avec qui ? Les interactions écologiques sont des processus majeurs qui influencent la coexistence des espèces et le fonctionnement des écosystèmes. Pour autant, les caractères phénotypiques qui confèrent aux espèces (ou aux génotypes) une aptitude à la compétition (ou à la coopération) élevée restent mal connus. C’est en particulier le cas pour les végétaux, tant sur les espèces sauvages que cultivées.

    De plus, la simplification des agrosystèmes couplée à l’utilisation massive d’intrants lors de la révolution verte a engendré une hausse sans précédent des rendements qui a permis de répondre aux besoins alimentaires des populations des pays industrialisés.

    Une des solutions envisagées pour limiter l’usage d’intrants, tout en maintenant des niveaux de production acceptables, est de réintroduire de la diversité dans les systèmes cultivés. Cette diversification des agrosystèmes peut se faire à l’échelle interspécifique comme dans les systèmes de culture associées (Bedoussac et al., 2015) mais aussi à l’échelle intraspécifique en cultivant des génotypes d’une même espèce en association au sein d’une parcelle.Cependant, augmenter la diversité dans une culture n’est pas toujours synonyme d’un meilleur fonctionnement de cette dernière. Les recherches doivent donc être poursuivies afin de concevoir des mélanges variétaux permettant d’assurer une productivité suffisante dans des agrosystèmes durables (Litrico & Violle 2015).

    Mon projet de thèse vise à comprendre par des approches comparatives en écologie fonctionnelle, qui s’appuie sur l’étude les variations de caractères, l’adaptation des plantes à leur environnement ainsi que les interactions qu’elles mettent en place. L’utilisation des traits fonctionnels est une manière d’appréhender la question de façon générique sous l’hypothèse que des traits candidats sont valides quelle que soit l’espèce (ou le génotype) considéré. J’étudie les interaction mises en place entre différents génotypes de blé dur afin de comprendre quels sont les mécanismes écologiques qui sous-tendent la relation diversité – productivité au sein de couverts monospécifiques. Je m’intéresse particulièrement aux traits racinaires qui restent encore peu étudiés à l’échelle des plantes cultivées.

    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.

    Intérêts personnels
    Mes travaux portent sur les réponses adaptatives des plantes herbacées pérennes aux sécheresses estivales sévères de type méditerranéen. Avec des approches écophysiologiques et agronomiques (menées à l’INRA), ce travail se positionne en collaboration étroite avec l’écologie fonctionnelle (Forecast - CNRS). L’objectif principal est d’analyser le fonctionnement des espèces et communautés herbacées sous contrainte hydrique forte dans le cadre du changement climatique. Un cadre conceptuel et terminologique unifié des stratégies adaptatives des plantes à la sécheresse a été proposé en 2018. Les études portent notamment sur la stratégie de dormance estivale et plus largement sur la généricité du compromis fonctionnel entre potentiel de croissance et survie au stress.

    Personal interests

    As an ecophysiologist, my research is focused on the adaptive responses of perennial herbaceous plants to severe summer droughts as occurring in Mediterranean and semi-arid areas. I have particularly analysed the adaptive strategies to cope with severe water deficit, such as summer dormancy. I am now developing collaborative research projects with geneticists and ecologists to understand plant traits and strategies associated with drought survival with application to plant breeding in forage species for better adaptation to increasing aridity under climate change.
