Invasive Species Have Larger Impact on Biodiversity

Invasive species influence biodiversity across larger spatial extents than previously thought. In a recently published study, researchers from Eawag and the University of Zurich show that the impacts of invasive species extend far beyond the ecosystems they invade and that three mechanisms are primarily responsible for this. These findings are of great importance for the management of ecosystems.

A recent study by researchers from Eawag and the University of Zurich reveals that invasive species have a larger impact on biodiversity than previously believed, affecting ecosystems beyond the ones they invade. Three mechanisms are primarily responsible for these extended impacts.

Invasive species are a major threat to global biodiversity, as they have a profound influence on the ecosystems they invade. Examples of cross-ecosystem impacts of invasive species from around the world have been compiled in a global overview for the first time.

The study highlights the need for a holistic management approach to invasive species. Invasive species can alter the flow of organisms and materials between ecosystems, change the quality of these flows, and create new spatial flows between ecosystems.

The effects of invasive species can extend up to 100 kilometers beyond the invaded ecosystem. The study provides examples, such as rats in the Chagos Archipelago and Himalayan balsam in Switzerland, to illustrate how invasive species can disrupt ecological processes and impact multiple ecosystems.

The importance of considering the broader spatial context when assessing the impacts of invasive species is emphasized, as their management requires a more comprehensive perspective. Understanding how invasive species affect exchanges between ecosystems can help target management efforts to mitigate their effects effectively..
