Expanding the invasion toolbox: including stable isotope analysis in risk assessment

Species introductions are a major concern for ecosystem functioning, socio-economic wealth, and human well-being. Preventing proved to be the most effective management strategy, various tools such as species distribution models risk assessment protocols have been developed or applied this purpose. These approaches use information on predict its potential invasiveness impact in case of introduction into new area. At same time, much biodiversity has lost due multiple drivers. Ways determine successful reintroductions once native but now extinct well assisted migrations yet missing. Stable isotope analyses commonly used reconstruct species’ feeding ecology trophic interactions within communities. Recently, method potentially arising absence target species. Here we propose implementation stable analysis an approach schemes increase accuracy predicting invader impacts success migrations. We review discuss possibilities limitations methods usage, suggesting promising useful applications scientists managers.
