Recent years have seen a steep rise in invasions of non-native species in virtually all major ecoregions on Earth. Along with this rise has come a realization that a rigorous scientific understanding of why, how, when, and where species are transported is the necessary foundation for managing biological invasions.

Invasive Species presents extensive information and new analyses on mechanisms of species transfer, or vectors, as the latest contribution from the Global Invasive Species Programme (GISP).
