Genomic vulnerability assessment reveals the potential benefits of adaptive introgression by mitigating the maladaptive risk of admixed populations.

ABSTRACT: As climate change accelerates, plant species largely rely on genetic variation to adapt and survive when they fail to track their ecological niches through range shifts. Predicted genomic vulnerability is able to identify populations lacking the necessary genetic variation for climate change adaptation. However, the role of introgression in genomic vulnerability remains poorly explored. Here, we used the dove tree (Davidia involucrata), a relict species native to southwestern China, to test whether introgression may reduce genomic vulnerability. By integrating population genomics and environmental data collected from 196 individuals of 18 populations, we identified 747 strictly climate-associated loci across the distribution range of D. involucrata, 138 of which were recovere
