    @Th_Lenormand

    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.

    Research interests by keywords
    adaptation, local adaptation, migration, speciation, (sex) chromosomes, clines, sex, parthenogenesis, meiosis, recombination, epistasis, dominance, mutations, resistance, duplications, modifiers, mating systems, sexual conflicts, parasites, microbiota.

    Personal interests

    As an ecophysiologist, my research is focused on the adaptive strategies of plants under drought (Volaire, 2018, Global Change Biology). I have particularly analysed the adaptive strategies to cope with severe water deficit, such as summer dormancy (Volaire & Norton, 2006, Annals of Botany). I also investigate the  dehydration tolerance and embolism resistance of perennial herbaceous plants under severe summer droughts as occurring in Mediterranean and semi-arid areas.  We proposed a critical view of the so called 'functional' traits that are increasingly challenged as unsuitable to fully understand plant and communities functioning (Volaire et al., 2021 Ecology and Evolution). As a consequence, I highlight the importance of seasonal phenological adaptations across species and types to survive dehydration stress (drought, frost), based on the important framework in ecology, the 'growth-stress survival' tradeoff' (Volaire et al., 2022 Annals of Botany). I am 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.

    Intérêts personnels
    Mes travaux portent sur les stratégies adaptatives des plantes à la sécheresse. Je travaille notamment sur les espèces herbacées pérennes sous sécheresses estivales sévères de type méditerranéen. Je couple des approches en écophysiologie, agronomie et écologie fonctionnelle. 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. Une revue multi-espèces et multi-stress a été publiée en 2023 dans Annals of Botany qui propose de considérer mieux la phénologie des plantes au travers d'un 'Plant economics spectrum' saisonnier.
