Summary: | This paper draws to a large extent on the recent benchmark review by Frenot et al. (2005) of the presence and status of non-indigenous (alien) species, carried out under the auspices of the RiSCC (Regional Sensitivity to Climate Change in Antarctica) programme of the Scientific Commitee on Antarctic Research (SCAR). The aim of the review was to document the current state of knowledge on alien species in terrestrial, marine and freshwater ecosystems of continental Antarctica, and the subantarctic in terms of extent, impact and implications, and taking into account contemporary changes in climate and patterns of human activities in these regions.
