Document Summary
Invasive species were shown to have higher trait means than non-invasive species for traits related to physiology, leaf-area allocation, shoot allocation, growth rates, size and fitness. Factors: propagule pressure, time since introduction, habitat type. The ability of a species to become invasive was not only determined by the characteristics of native distribution, but also directly by species life form and strategy (+ more) Traits that offer an advantage at a given stage in a particular habitat may be neutral or even detrimental at another phase and/or a different habitat: 2. Comparisons of alien species differing in the degree of invasiveness in the introduced range are the most direct test of determinants of invasiveness: 3. Absence of data on some traits important for sexual reproduction, yet it is these traits that are highlighted as important in some studies. Studies using those rarely available traits are also usually constrained by a limited number of species: 4.
