  • Mes recherches se situent à l’interface de la biologie évolutive, de l’écologie comportementale et de la biologie de la conservation. Je m'intéresse à la façon dont l'habitat et les interactions interspécifiques façonnent les réponses écologiques et évolutives de l’échelle de la population à celle de l'espèce. Mon thème de recherche primaire porte sur l'écologie sensorielle et plus particulièrement sur l’évolution des systèmes de communication. Un second axe de recherche concerne la Biologie de la conservation. Une partie des travaux a porté les oiseaux prairiaux dans les plaines inondables. Ces deux axes se fondent dans l’étude des conséquences écologiques et évolutives de deux facteurs contribuant aux changement globaux : les invasions biologiques et la pollution lumineuse.

    My research is at the interface between the fields of Evolutionary Biology, Behavioral Ecology, and Conservation Biology. I am interested in the processes by which habitat and interspecific interactions shape the ecological and evolutionary responses from the population to the species scale. My primary research topic is sensory ecology and, more specifically, the evolution of communication systems. A second research axis focuses on Conservation Biology. Part of former investigated grassland birds in floodplains. These two axes merge to address the ecological and evolutionary consequences of two factors contributing to global changes: biological invasions and light pollution.

    Ecologie visuelle des amphibiens

    Les amphibiens exploitent des habitats aquatiques aux propriétés optiques très variables. En particulier, les longueurs d’onde ultraviolettes sont filtrées en fonction de la concentration des acides humiques issus de la dégradation de la végétation. Malgré la stochasticité de leur environnement visuel, la sensibilité à l’ultraviolet semble largement répandue parmi les urodèles. Chez les Lissotritons elle est impliquée dans la communication sexuelle et la capture de proie. L’expression des photorécepteurs est elle-même modulée par les conditions photiques rencontrées lors du développement. Les travaux portent sur les réponses évolutives de l’ensemble du système de communication à la variation de l’environnement photique et sur les conséquences pour le risque d’hybridation entre espèces.

    Amphibians use aquatic habitats which optical properties are very variable. In particular, ultraviolet wavelengths are filtered according to the concentration of humic acids that originate from vegetation decay. In spite of this high stochasticity of their visual environment, ultraviolet sensitivity seems widespread among urodeles. In Lissotriton newts, it is involved in sexual communication and prey capture. The expression of photoreceptors is also modulated by the photic conditions experienced during development. I investigate the evolutionary response of the whole visual communication system to the variation of the photic environment and the consequences on the hybridization risk between species.



    Pollution lumineuse

    Les éclairages artificiels nocturnes sont principalement générés par les zones urbaines et les routes. La lumière est diffusée dans l’atmosphère et reflétée vers le sol loin de sa source, exposant ainsi de grandes surfaces de territoire. En modifiant la photopériode, ce phénomène altère la physiologie, le comportement des individus, et les interactions entre organismes. Ce phénomène est maintenant reconnu comme une menace globale pour la santé humaine, la faune et les écosystèmes. Cependant, nous manquons encore de données biologiques pour évaluer les effets sur les populations naturelles et modéliser ces effets dans l’espace. Les travaux portent sur ses questions en prenant les amphibiens comme modèle et en combinant mesures in situ, expériences contrôlées en laboratoire et modélisation spatiale par SIG.

    Artificial light at night is mainly generated by urban areas and roads. Light is scattered in the atmosphere and reflected back to the ground away from its source thus effectively exposing large areas. By modifying the photoperiod, this phenomenon alters physiology, behavior of individuals, and interactions between organisms. Artificial light at night is now recognized has a global hazard for human health, wildlife, and ecosystems. However, we still largely lack biological data to assess the effects in natural populations and spatial model of theses effects. This project investigate these issues and focuses on amphibians as model organisms by combinining in situ measurements, controlled experiments in the lab, and GIS modelling.



    Invasions biologiques

    Les invasions biologiques constituent une menace majeure de la biodiversité à l’échelle mondiale. Elles interrogent notre capacité à prédire l’expansion d’une population introduite, son impact sur les écosystèmes colonisés, les processus évolutifs impliqués, et au final à contrôler les populations invasives. Le projet européen Life CROAA "Control strategies of Alien Amphibians" vise à contrôler deux amphibiens majeurs le Xénope lisse Xenopus laevis et la Grenouille taureau Lithobates catesbeianus introduits en France et qui menacent les communautés des zones humides. Ses objectifs de recherche sont de tester des stratégies alternatives de contrôle intégrant des modèles de connectivité, les paramètres démographiques des différents stades et d’améliorer l’efficacité des techniques de capture.

    Biological invasions are now considered as a major threat to Biodiversity across the World. They raise questions about our capacity to predict the spread of an introduced population, the impacts on colonized ecosystems, the evolutionary processes involved, and ultimately to control invaders. The European Life project CROAA "Control strategies of Alien Amphibians" aims at controlling two main invasive amphibians the African clawed frog Xenopus laevis and the Bullfrog Lithobates catesbeianus that threatens wetland communities where they have been introduced in France. Its research objectives are to test alternative control strategies integrating connectivity modeling, demographic parameters of the different life stages, and to improve the efficiency of capture methods.
