Abstract: Local adaptation is a key evolutionary process that allows species to adapt to different habitats across their geographic range and ultimately survive environmental heterogeneity. However, evidences are accumulating that local adaptation is threatened in several species as a result of rapid climate change, which is inducing marginal populations to experience a genetic lag towards the newly established conditions. For this reason, an increasing effort is currently profused by the scientific community to characterize the genes underlying local adaptation in order to devise effective management strategies like assisted gene flow or ad hoc translocations. Among the most promising tools available to characterize adaptive variability is landscape genomics, an integrative approach combining GIS and genomic analysis that is able to associate focal selective pressures to specific genomic regions harbouring genes of adaptive relevance. This webinar will aim to frame the theoretical, statistical and bioinformatic background of landscape genomics, to discuss its current limitations, as well as to overview the ways its findings can be exploited to estimate genetic maladaptation and set priorities for the conservation of local genomic resources
