Abstract:
Invasive alien species are increasingly being recognized as important drivers of ecological change. We have advanced a dynamical model of exotic invasion based on competition and dispersal trade on. The effects of the competition and dispersal abilities on invasion,and the responses of exotic invasion to habitat destruction have been simulated in this paper. The results show that: ( 1) The introductions of alien species will threaten the species with similar competition first,and then the poorer competitors. ( 2) The order of extinction induced by invasive species will rank from the best to the poorest. ( 3) The responses to habitat destruction will vary according to the odd-ranked and even-ranked species.
