Pensoft Publishers) Alien species management in cities can be a difficult and costly endeavour. In their study, published in the open-access journal Neobiota, scientists present a new tool developed to identify non-native species likely to become the next big invader. By using this approach, species considered of particular risk are to be taken measure of well before they have established. The prioritisation tool could be customised to answer the specific needs of different cities around the world.
