Population genomic and historical analysis suggests a global invasion by bridgehead processes in Mimulus guttatus
Abstract Imperfect historical records and complex demographic histories present challenges for reconstructing the history of biological invasions. Here, we combine historical records, extensive worldwide and genome-wide sampling, and demographic analyses to investigate the global invasion of Mimulus...
