Is Antarctica under threat of alien species invasion?

The last decade has seen a rapid development of scientific, logistic and tourist activities, especially in the Antarctic region with the mildest climatic conditions: the Antarctic Peninsula. This region is also exhibiting rapid regional warming and all of the already diagnosed alien species in the Antarctic Treaty Area were found within the Antarctic Peninsula. Identifying potential invasive species that can threaten this pristine area of the Earth helps us to take specific preventive actions.
