The introductions of non-native fish species affect the isotopic structure of recipient communities across the globe
Multiple anthropogenic pressures including the widespread introduction of non-native species threaten biodiversity and ecosystem functioning. Non-native species have been reported to induce ecological impacts across levels of biological organization ranging from genes to ecosystems, yet our understanding of how they affect recipient communities is still limited. Once introduced, non-native species interact with native organisms notably through competition and predation, potentially modifying the network of interactions between coexisting species and the trophic structure of recipient communities.
