The model compares the seed floating ability of the non-invasive alien species (‘NIAS’) I. balfourii and the invasive alien species (‘IAS’) I. glandulifera from populations differing in age. The three phases of the experiment are shown: “Second 20”, “Second 960” and “Second 12,480” (see “Materials and methods”)
