Although both the general-purpose genotype hypothesis and the hypothesis about the evolution of invasiveness predict that invasive species are characterized by particular traits that confer invasiveness, what these traits
A lthough both the generalpurpose genotype hypothesis and the hypothesis about the evolution of invasiveness predict that invasive species are charaeterized by particular traits that confer invasiveness, what these traits are still remains unclear. A theory put forward by a CAS botanist and colleagues suggests that the success of an invasive plant in a new habitat is due to the allocation of more nitrogen to its photosynthesis. As reported in a recent issue of Oecologia, the hypothesis has been supported by their research on the metabolic comparison between an invasive shrub and five native plants.
