AimAssessing the consequences of a future increase in non-native species introductions and native species extirpations on taxonomic similarity among fish faunas. LocationWorld-wide. MethodsWe designed 42 scenarios of future species introductions and extirpations to simulate future fish composition for 1054 river basins. Using these simulated future compositions, we computed the change in taxonomic similarity among pairs of fish faunas from historical to future situation at the river basin, biogeographic realm and world scales. ResultsAccording to all our scenarios, taxonomic similarity among fish faunas will strongly increase in the future at the three spatial scales considered. Fish faunas from the Southern Hemisphere, which are currently the less...
