Thèmes de Recherche.
My research activities mainly focus on documenting genetic diversity to study the evolutionary process shaping the distribution of genetic variation among individuals, populations, and species. I use genetic and genomic approaches to address a variety of questions in evolutionary biology (reproduction system evolution, Invasive biology, conservation genetics, community ecology).
Currently, I work on the ANR project DRIVE (PI E.Pante) which focuses on the unique mitochondria inheritance system in Limecola balthica (Fig1), the double uniparental inheritance (DUI). This sytem could cause mito-nuclear genetic incompatibilities (MNI) which have recently gained recognition as an important cause of hybrid breakdown and reproductive isolation. I will investigate whether DUI can play a significant role in maintaining barriers to gene flow among divergent populations by the way of MNIs

Fig2: Gene maps of Limecola balthica. All genes are encoded on the heavy strand, total genome lengths are reported inside their corresponding genome. Gene colors correspond to functional groups (OXPHOS gene families, tRNAs and rRNAs). Modified from Capt et al. (2020)
