Recherche My research focuses on the evolutionary effects of the environment. It articulates through the study of genetic data from (i) natural and (ii) experimental systems, to tackle the effects of (iii) climate, (iv) habitat loss and fragmentation, and (v) landscape components, whether they are (vi) human-driven or (vii) from natural origin. In that respect, I use phylogeography, population and landscape genetics at various temporal and spatial scales. I take advantage of the exceptional natural evolution laboratory that Madagascar offers to study at the country/island level, the evolutionary mechanisms that drove large radiations such as nocturnal cryptic lemur genera (Lepilemur and Microcebus) or endemic Malagasy olive trees (genus Noronhia). At lower temporal and spatial scales, using a semi-natural experimental facility (Metatron, France) and wild populations (Common lizards, Malagasy olive trees, lemurs), I assess the effects of climate change, habitat loss/expansion, and fragmentation and attempt disentangling their relative confounded effects.
