Studies have shown that invasive alien species (IAS) are responsible for a fifth of animal extinctions for which the causes are well-known, but are invasive species a treat to global biodiversity? In this paper, researchers assessed the spatial and taxonomic relationship between IAS and threatened vertebrates worldwide.
