This study uses genome-wide data to investigate the colonization history and genetic structure of the invasive plant Cotula coronopifolia, revealing multiple lineages, high selfing rates, and the role of dispersal in its spread.

The paper uses genomic, cytometric, and morphometric data to clarify taxonomic relationships in the Juncus bufonius complex, finding that polyploids and diploids are distinct taxa, and morphometric characters are not reliable for species delimitation.
