Abstract
Mediterranean and Alpine forests are among the most sensitive ecosystems to climate change. Significant progresses have been made in the prediction of their future response by the development of statistical and process-based models integrating functional traits. However, these approaches do not take the evolutionary potential of species into account. This project aims to fill this gap by assessing in-situ the adaptive potential - usually measured by common garden experiments - of four of the most abundant alpine tree species. To depict the potential response of these key species to selective pressure induced by climate change, individuals will be sampled along a large environmental gradient in plots with various diversity, and genotyped using SNP markers. Candidate SNPs for the local adaptation of trees will be detected with genome scans. Ultimately, these SNPs will allow detecting patterns of multigenic selection in response to critical local conditions impacted by climate change, either abiotic (aridity) or biotic (species richness).
