Resumen:
Summary1. We provide a brief overview of progress in our understanding of introduced plant species.2. Three main conclusions emerge from our review: (i) Many lines of research, including thesearch for traits that make species good invaders, or that make ecosystems susceptible to invasion,are yielding idiosyncratic results. To move forward, we advocate a more syntheticapproach that incorporates a range of different types of information about the introduced speciesand the communities and habitats they are invading. (ii) Given the growing evidence for theadaptive capacity of both introduced species and recipient communities, we need to consider theimplications of the long-term presence of introduced species in our ecosystems. (iii) Several foundationalideas in invasion biology have become widely accepted without appropriate testing, ordespite equivocal evidence from empirical tests. One such idea is the suggestion that disturbancefacilitates invasion.3. We use data from 200 sites around the world to provide a broad test of the hypothesis thatinvasions are better predicted by a change in disturbance regime than by disturbance per se. Neitherdisturbance nor change in disturbance regime explained more than 7% of the variation in the%ofcover or species richness contributed by introduced species. However, change in disturbance regimewas a significantly better predictor than was disturbance per se, explaining approximately twice asmuch variation as did disturbance.
