Global threats from invasive alien species in the twenty-first century and national response capacities

摘要: Invasive alien species (IAS) threaten human livelihoods and biodiversity globally. Increasing globalization facilitates IAS arrival, environmental changes, including climate change, facilitate establishment. Here we provide the first global, spatial analysis of terrestrial threat from in light twenty-first century evaluate national capacities to prevent manage invasions. We find that one-sixth global land surface is highly vulnerable invasion, substantial areas developing economies hotspots. The dominant invasion vectors differ between high-income countries (imports, particularly plants pets) low-income (air travel). Uniting data on causes introduction establishment can improve early-warning eradication schemes. Most have limited capacity act against In particular, reveal a clear need for proactive strategies with high poverty levels, low historical levels invasion.
