Abstract

Forest ecosystems are key for human society, but their structure and functioning could be greatly impaired by climate change, which is expected to strengthen the loss of biodiversity, and to generate an upward and northward climatic niche shift. Forest trees are long-lived and sessile organisms, whose migration potential and long-term genetic adaptation are likely too slow to face climatic change. Nevertheless, populations will be able to survive in their present locations only if they are equipped with adaptive capacity to future changes. The project will focus on a conifer species, Pinus pinaster, widespread in the Mediterranean area. Genotyping data will be used to infer overall population properties (such as effective population size, frequency of deleterious alleles, frequency of loci under selection) that allow to describe a populations' adaptive potential but at the same time do not require intensive sampling and deep sequencing, so to keep costs low (this is an important matter for the implementation of end-user compliant methods) ("capturing and characterising the genetic diversity in germplasm and revealing novel information").
