Using stable isotopes to analyse extinction risks and reintroduction opportunities of native species in invaded ecosystems

Abstract Invasive non-native species have pervasive impacts on native biodiversity, including population extirpations and species extinctions. Identifying reasons why a population of a native species is extirpated following an invasion often relies on literature-based results of anecdotal observatio...
