| Summary: | This study maps and evaluates the impact of invasive alien species (IAS) across mountain ranges worldwide, identifying areas of high impact and problematic taxa. We hypothesise that elevation, IAS richness, and biogeographic location drive variability in the cumulative impact of IAS in mountain ranges, measured using an adapted version of the CIMPAL index. Tweedie's compound Gamma-Poisson models show significant effects of these variables on standardised CIMPAL scores. Mapped CIMPAL scores reveal spatial heterogeneity and distinct hotspots, notably in the Alps, French Massif Central, Appalachians, Rocky Mountains, and Taiwan. Key IAS consistently contribute to high impacts. |
