    My research is centered in the theoretical framework of evolutionary ecology, population biology and behavioural ecology. My projects aim at understanding life history variation in order to determine the adaptive and evolutionary processes that explain and maintain animal diversity. I´m particularly interested by three kinds of life history traits linked to behavior: cooperation, animal communication and maternal invesment. I'm mainly using birds as biological models. I'm mainly using empirical methods, including large-scale experiments and analyses of long-term data sets on different populations of passerine birds in the field.

    I'm currently working on four main projects. 1) Evolution of colour ormentation in birds(with a special focus on female coloration and blue tits) 2) the cause and life history traits consequences of cooperation in sociable weavers ; 3) Sexual and social evolution on islands, and 4) the evolution of weaver nests. I'm also part of  the art-science project Obô.

    * Evolution of female colour ornementation

    In this project we use a combination of empirical and comparative approaches to address three fundamental questions on sexual and social selection in both monomorphic species and dimorphic species in which females present conspicuous traits. Our questions are the following (i) Are female conspicuous traits under sexual /social selection ? (ii) Do female conspicuous traits reflect female quality and which mechanisms maintain signal honesty? (iii) What are the population consequences of female signalling and mutual sexual selection.

     * Evolution of plumage ornement in space and time

    Selection often varies in space and time and long-term research that spans broad spatial scales is needed to understand the factors driving phenotypic variation and to assess the links between traits and fitness.  To assess the importance of spatiotemporal variation  and its consequences on selection estimates, we collected data on two study systems: (i) the blue tit (yellow and UV-blue colorationsmeasured by spectrophotometry since 2005, 600 birds measured each year); (ii) the  size of the sociable weaver melanin patch  since 2010 (the bib patch is photographied each year on 400 individuals)

    The project aims at understanding the fitness bases of cooperation and the consequences of cooperation for population dynamics through its effects on reproductive output, survival and dispersal. Our study model is an endemic passerine bird from southern African passerine. This bird is a cooperative breeder. In cooperatively breeding species, mature individuals called ‘helpers’ assist the breeding pairs by bringing additional food to the nest. We work on the evolution of different cooperative behaviours – cooperative breeding, nest building and predator mobbing and on the relationship between cooperation, fitness, dispersal and long-term population dynamics.

    Currently our project has two main aims: (i) determining whether sexual or social selection play a role in the evolution of cooperation and thus the role of partner choice ; (ii) determining  how presence / absence of co-operators affects maternal effects and parental investments

      3- Evolution on islands

    TEAM:  Rita Covas (CIBIO, Portugal), FitzPatrick Institute, Univ Cape Town), Martim Melo(CIBIO),  Claire Loiseau ( Univ Montpellier), Ana Leitao (Post doc ); Raquel Ponti (Post doc)

    Islands are unique ecosystems sharing a distinctive set of characteristics that make them particularly interesting to study adaptation by organisms. The isolation and reduced area of islands result in simplified ecological ecosystems and an impoverished fauna that are expected to lead to convergent patterns of adaptation (the ‘insularity syndrome’). Our aim is to establish, using comparative work , whether island birds worldwide display such convergent shift for ornamentation, songs, behaviour and morphology. Then we aim at determining which factors lead to those changes and are particularly interested by the role of parasitism and interspecific competition. We worked on data collected in natural history museum and in the field (Sao Tome, Madeira, Gabon, Cameroun).

Cape Town) , Staffan Andersson(Univ.  Gothenburg), Fanny Rybak(Univ. Paris Sud), Doris Gomez(CEFE), Paul Dufour (Univ. Grenoble), Pietro d'Amelio (Post doc)

    Our aim is to work on one of the most spectacular and diverse radiations of extended phenotypes, the intricate and complex nest architectures of weaverbirds (family Ploceidae, 117 species in 16 genera), varying from the exquisite lace-like Malimbusnests to the rough thatch of the communally built sociable weaver nests . Our central aim is to investigate the role of sexual selection on the evolution and diversification of i) nest architecture (the extended phenotype) and ii) nest building behaviour (a potential associated display) and, for both traits, to determine how they relate to the classic ornaments in this group – striking colours, songs, and flight displays.

    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.).

    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).

    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.

    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.
