Population genomic and historical analysis suggests a global invasion by bridgehead processes in Mimulus guttatus

Vallejo-Marín et al. combine historical records, extensive worldwide and genome-wide sampling, and demographic analyses to investigate the global invasion of Mimulus guttatus from North America to Europe and the Southwest Pacific. They found that M. guttatus was first likely introduced to the Britis...

Description
Summary:Vallejo-Marín et al. combine historical records, extensive worldwide and genome-wide sampling, and demographic analyses to investigate the global invasion of Mimulus guttatus from North America to Europe and the Southwest Pacific. They found that M. guttatus was first likely introduced to the British Isles from the Aleutian Islands (Alaska), followed by admixture from multiple parts of the native range, and hypothesise that populations in the British Isles then served as a bridgehead for vanguard invasions worldwide.
