Most island vertebrate extinctions could be averted, concludes new study

Eight of every ten species extinctions has occurred on islands, and invasive mammals are the leading reason for those losses. Currently, 40 percent of species at risk of global extinction are island inhabitants. In the most thorough study of its kind, scientists have now analyzed global patterns of island vertebrate extinctions and developed predictive models to help identify places where conservation interventions will provide the greatest benefits to threatened island biodiversity.
