    Research interests

    Soil scientist fascinated by plant ecophysiology, my research focusses on soil-plant interactions in both natural and controlled conditions. I am particularly interested in silicon (Si), a major component of the Earth’s crust and soils, that is increasingly considered as a key element in plant ecology and agriculture through the fantastic process of biosilicification (mineral deposits in plant organs as seen on the left).

     

     

    Research thematic

    I combine expertise in soil science and plant ecophysiology to work on three different research axes:

    • The influence of soil properties, and in particular their evolution over time through the use of long-term chronosequences, on silicon cycling (e.g., soil Si pools and fluxes, Si availability for plants, Si uptake by plants and silicification, biological versus lithological control on Si cycling)
    • The control of overlooked biotic factors on soil-plant Si mobility (e.g., soil microorganisms, large herbivores, root exudates), and how they could be leveraged to increase crop Si status through specific agricultural practices.
    • Developing functional trait-based approaches to better understand the role and functions of Si and silicification in plant ecophysiology, and how it aligns with major ecological theories (plant growth/defense tradeoff, plant economics spectrum, resource availability hypothesis, etc.).

    I study how variation in signal production and perception influences (i) the evolution of signals in multiple sensory modalities (acoustic, visual and chemical domains) and (ii) the adaptation (through phenotypic plasticity and/or genetic variability) to different environments, a topic for which there is nowadays a growing interest in the new field of sensory ecology, notably to understand how species cope with their rapidly changing environment due to anthropogenic activities.

    Current Research

    I work to reveal how animals perceive and adjust to their environment, and why this matters for populations and ecosystems. My model of choice: large herbivores. Because you can (relatively) easily monitor their behaviour in natura, and they have important ecosystem effects. Some have high societal and economical values, so my research sometimes matter beyond basic science. We (as humans) are making the world's climate different. How this affects organisms in the hottest applied ecological question. I do my share to bring an answer to it

    @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.

    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.
