Contrasting patterns and processes of biological invasions in
blue versus green ecosystems

This project contributes to the Blue Green Biodiversity Research Initiative – an Eawag-WSL collaboration focusing on Biodiversity at the interface of aquatic and terrestrial ecosystems.

We compare invasions in aquatic and terrestrial ecosystems primarily at large (national) spatial scales and among several higher-level taxa (insects, molluscs, crustaceans, all major vertebrate classes, and plants). We calculate native-exotic richness ratios and test the biotic resistance hypothesis while simultaneously accounting for other potential factors that could influence invasiveness and invasibility (i.e., species traits, propagule pressure, and the size of species pools).
