Invasive non-native species likely to threaten biodiversity and ecosystems in the Antarctic Peninsula region.

摘要: The Antarctic is considered to be a pristine environment relative other regions of the Earth, but it increasingly vulnerable invasions by marine, freshwater and terrestrial non‐native species. Peninsula region (APR), which encompasses Peninsula, South Shetland Islands Orkney Islands, far most invaded part Antarctica continent. risk introduction invasive species APR likely increase with predicted increases in intensity, diversity distribution human activities. Parties that are signatories Treaty have called for regional assessments risk. In response, taxonomic experts undertook horizon scanning exercise using expert opinion consensus approaches identify present highest biodiversity ecosystems within over next 10 years. One hundred three species, currently absent APR, were identified as relevant review, 13 presenting high invading APR. Marine invertebrates dominated list flowering plants also represented; however, vertebrate thought unlikely establish year timeframe. We recommend (a) further development application biosecurity measures all stakeholders active including surveillance such those during this exercise, (b) use methodology across Antarctica. Without appropriate measures, rates introductions increase, resulting negative consequences whole continent, introduced spread due climate change increasing activity.
