These maps show how the introduction of additional non-native species would affect biodiversity patterns at the global scale. According to all our scenarios taxonomic similarity among fish faunas would strongly increase in the future, and the Southern Hemisphere, which is currently the less affected by taxonomic homogenization, shows the steepest forecasted changes.
