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.).

Directeur de Recherche ( DR1)/Directeur du CEFE

Mes travaux portent sur la compréhension de la régulation du fonctionnement des écosystèmes terrestres en terme de flux de matière (eau, carbone, nutriments…). Initialement centrées sur les écosystèmes méditerranéens, mes activités ont été élargies à d’autres écosystèmes subissant de très fortes contraintes (les hauts plateaux andins). 

My research focuses on the understanding of terrestrial ecosystems functioning in terms of fluxes (water, carbon, nutrients...). Initially centered on Mediterranean ecosystems, my research activities have been extended to the Andean highlands).

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.

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.
