| Abstract |
The oceans surrounding Antarctica represent one of the last pest-free regions of the world. However, climate change is breaking down the barriers to invasion, putting these ecosystems at risk. This work represents the first comprehensive risk assessment for the threat of marine invasive species to nearshore environments around Australia’s Antarctic research bases and subantarctic islands. The overall risk of marine invasive species is high, due to the potential for invasive species to plausibly cause native species extinctions in the study locations. Strengthening invasive species policy at national and international levels will help to reduce this threat to these locations. |
