Research
Current research topics
I am applying molecular biological techniques and methods in population and quantitative genetics to questions in evolutionary ecology and conservation biology. I am interested in the evolutionary and ecological mechanisms (neutral or selective) that shaped the genetic and phenotypic variation within wild populations living in human-dominated landscapes marked by spatial trade-offs between risk avoidance and resource acquisition.
My previous research at INRAE CEFS (Toulouse) was focused on the genetic architecture and evolution of morphological, life history and behavioural traits (movement tactics and land use) in wild ungulate populations. My main research interest in Rennes is on the genetic and environmental determinants of the intra-specific variation in diet and foraging strategy of top predators and consequences on ecosystem functioning: I study how individual diet vary depending on their genetic/ecological characteristics and biotic and abiotic environmental conditions. The challenge is to assess the interplay between plastic and evolutionary responses to human-induced environmental perturbations. To this end, I develop a wild quantitative genetic approach based on genomic relatedness data. At the community level, I am also interested in the cascade effects of this intraspecific variation in diet of predators on the structure of trophic networks.
I dedicate a large part of my time to the development of eDNA approaches (DNA metabarcoding from water, feces or gut samples) to characterize fish and invertebrate composition in rivers/lakes, survey invasive species/pathogens or study interactions between predators and prey communities in freshwater or marine, tropical or temperate ecosystems in complement to isotope analysis (project REZOFLEUVE, LAMINET).
