PhD Subject : Extinction or persistence of warm drylands tree species face to global change ? Biogeographic modelling approach and conservation genomics applied to dragon trees.

My PhD project aims to decipher the role of biological, ecological, and evolutionary factors on tree species vulnerability face to global change in warm and arid environments. Firstly, my work focuses on climate change vulnerability of hundreds of tree species in the future at global scale, accounting for both sensitivity and exposure, using online big data bases and climatic niche analysis. Secondly, a study case is developed on Macaronesian dragon trees (Dracaena draco sensu lato), using genomic tools, to address mechanisms at a finer scale.

Key words : biogeography - conservation biology - niche ecology - global change - spatial analysis - big data - phylogeography - phylogenetics - genomics
