Speciation, environmental gradients and hybrid zones : the case of the Mascarene grey White-eye Zosterops borbonicus

 

Thèmes de recherche

During my PhD, I worked on the diversification of an island bird : the Mascarene Grey White-eye (Zosterops borbonicus). This species, endemic to the island of Réunion (Indian Ocean), represents an extreme case of within-island diversification. I used population genetic tools and hybrid zone theory in order to decipher the relative roles of historical, environmental and neutral factors in the emergence and maintenance of this diversity. I was particularly interested in the dynamics of the different hybrid zones which are found between each of the geographical colour form of the species.

For my postdoctoral project, I am working in quantitative genetics on a long-term dataset collected in wild populations of Blue Tit (Cyanistes caereleus) in Southern France and Corsica. I aim to understand how the interplay between selection, migration and G matrix affect differentiation among populations. I am using different approaches such as multivariate QST – FST comparison and comparison of genetic (co)variances and heritabilities for various traits (morphology and life history traits) across populations experiencing contrasted environmental conditions.
