Research themes

        The central topic of my research consists in the study of the genetic polymorphism of
natural populations in order to infer their past and present history and functionning.
These studies are motivated by questions related to evolutionary biology as well as
conservation biology. They have been conducted on various organisms (marine gastropods,
terrestrial mammals...) and in different ecological situations.
My past and actual researches are more precisely related to the following topics:

Estimation of dispersal rates and gene flow
Estimation of dispersal rates and modalities (sex-biased, age-classes…) - Inferences on
gene flow, delimitation of populations in equilibrium and non-equilibrium situations -
Comparison of „population based‟ and „individual based‟ methods.

Understanding and managing biological invasions
Determination of colonisation scenarios - Genetic monitoring of eradication campaigns using
microsatellite markers - Genetic definition of eradication units - Evaluation of an eradication

Past and present estimations of population sizes using molecular markers
Comparison of instant and temporal estimations of population size. Comparison of genetic
based and field based (capture) estimations of population size. Detection of bottleneck using
genetic polymorphism.

Linking local population functioning to phylogeographic patterns
Analysis of population structure and history using both mtDNA haplotypes and
microsatellites markers - test of biogeographic barriers.

Influence of larval development on genetic differentiation in marine species
Comparison of population structure and differentiation in planctotrophic vs non-
planctotrophic species of gastropods - Linking dispersal abilities to genetic differentiation and
ultimately, to speciation speeds.

> Ongoing collaborations:

ecological population structure of Norway rats (Rattus norvegicus) on a small and recently
invaded island.

- with Sarah Samadi and Michel Pascal, Natural History Museum of Paris and National
Institute for Agronomical Research of Rennes, France: Genetic structure and
phylogeography of insular populations of the lesser white-toothed shrew (Crocidura
