This study investigates the factors limiting the northward spread of invasive knotweed through a transplant experiment, finding that low temperatures reduce below-ground biomass and hinder expansion.

This study uses herbarium records to analyze long-term changes in stomatal and leaf traits of invasive knotweeds over 160 years, finding shifts in stomatal size and shape linked to CO2 levels and climate.

This study examines phenotypic plasticity and population differentiation in Japanese knotweed across Europe using a common garden experiment, finding high plasticity but little local adaptation.

This study uses herbarium genomics to trace the origin and global spread of Japanese knotweed, revealing genetic patterns and hybridization events across its native and introduced ranges.
