  • Study Notes

    • Predicting the spread of alien species is an urgent challenge.
    • Most predictions use models of ecological niche but may have limited accuracy.
    • An alternative approach is based on environmental resistance of the landscape.
    • This approach uses gradients of biotic similarity to predict likely routes of spread.
    • Environmental resistance predicts patterns of spread better than null or climate matching models.
    • The approach can be used to simulate future spread and reveal regional differences in invasion risk.
    • Invasion risk is shaped by proximity to existing hotspots and gradients in environmental resistance.
    • Environmental resistance provides a complementary approach for predicting invasion risk.
    • The approach can be rapidly deployed even when information on niche or identity of invaders is unknown.
    • The study focused on the global alien avifauna.
