Hotspots of plant invasion change from subtropical towards temperate regions
An international research team led by the University of Vienna has produced, for the first time, high-resolution global maps of invasion risk for thousands of alien plant species under current conditions and future climate and land use scenarios. Their results show that global hotspots of plant invasion risk will shift geographically, with temperate regions facing increasing risks, while risks may decline in some subtropical areas. The study was published in Nature Ecology & Evolution.
