PhD project :

In the context of climate change, understanding the basis of local adaptation of species along environmental gradients is essential. During my PhD, I study butterfly adaptation along the altitudinal gradient in Europe. I’m more particularly studying the role of phenology as a response and adaptation factor to climate change with altitude, using a population genomics approach.

A set of twenty target species, that varying in phenology with altitude, are study using population genomics analyses in order to understand how genetic structure, local adaptation, and demographic history of populations vary along the altitudinal gradient.

One of the main hypotheses is that species exhibiting a strong shift in phenology with altitude (change in the number of generations and/or phenology) should present a more restricted gene flow between altitudes due to the time shift in phenology between populations.

Going forward, at high altitude the favorable season is shifted in time and shorter. However, since the photoperiod is constant with altitude, the photoperiod response signals for diapause induction and butterfly emergence should therefore be locally adapted so that butterflies emerge at the beginning of the favorable season and enter diapause at the end. So I expected to find candidate loci, with an higher differenciation with altitude, involved in the determinism of phenology.

During my PhD I do field work, molecular biology, bio-informatics and analysis of population genomics.
