Failure to invest below-ground may limit the Northern expansion of invasive knotweed: lessons from a two-phase transplant experiment

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.

Long-term stomatal and leaf trait dynamics in invasive knotweeds in Europe - insights from 160 years of herbarium records

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.

Phenotypic plasticity of invasive knotweed across Europe: a distributed common garden experiment

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.

Bird population trend analyses for a monitoring scheme with a highly structured sampling design

The paper develops a GAMM-based workflow to analyze bird population trends from structured monitoring data, addressing spatial bias, observer variation, and zero-inflation, and validates it against existing methods.

General purpose genotypes and evolution of higher plasticity in clonality underlie knotweed invasion

The paper examines phenotypic variation in Reynoutria japonica across native and introduced ranges, finding higher clonality and plasticity in introduced populations compared to native Chinese populations.
