Data from: Correlation of native and exotic species richness: a global meta-analysis finds no invasion paradox across scales
Support for the “biotic resistance hypothesis,” that species-rich communities are more successful at resisting invasion by exotic species than are species-poor communities, has long been debated. It has been argued that native-exotic richness relationships (NERR) are negative at small spatial scales...
