A complex interplay of genetic introgression and local adaptation during the evolutionary history of three closely related spruce species.

ABSTRACT: As climate change triggers unprecedented ecological shifts, it becomes imperative to understand the genetic underpinnings of species' adaptability. Adaptive introgression significantly contributes to organismal adaptation to new environments by introducing genetic variation across species boundaries. However, despite growing recognition of its importance, the extent to which adaptive introgression has shaped the evolutionary history of closely related species remains poorly understood. Here we employed population genetic analyses of high-throughput sequencing data to investigate the interplay between genetic introgression and local adaptation in three species of spruce trees in the genus Picea (P. asperata, P. crassifolia, and P. meyeri). We find distinct geneti
