Generalist‐pollinated Arabis alpina exhibits floral scent variation at multiple scales
Nordic Journal of Botany, EarlyView.Plants that depend on animals for reproduction often use complex floral traits to attract pollinators. Floral scent is recognized as part of the pollinator attraction module and can be shaped by plant‐pollinator interactions. In recent decades, research has started to reveal the dynamic properties of floral scent, identifying patterns of spatial and ...

Sexual reproduction in invasive Japanese knotweed (Reynoutria japonica) in south Sweden
Nordic Journal of Botany, EarlyView.To understand the potential for northward expansion of knotweeds into currently uninvaded regions, it is crucial to assess the potential for sexual reproduction alongside the ongoing vegetative spread. For that reason, we tested viability in Reynoutria japonica seeds in south Sweden, a region where viable seeds had not been previously reported ...

Oikos, EarlyView.Plant traits and their tradeoffs are major determinants of plant functions. Although trait‐based frameworks should apply to plant functioning at any life stage, they have been primarily established for adult plants. Therefore, we lack comprehensive trait‐based studies of seedlings across multiple species to prove which key dimensions of trait variation
