Invasive non-native species in Brazil: an updated overview.

Invasive non-native species (invasive species, henceforth) across all taxonomic groups are spreading globally, with numbers projected to continue growing in the future. It is difficult for governments and managers to handle this issue when the identity of invasive species or the areas of occurrence of biological invasions are not known. Here, we provide an updated list of invasive animals, plants and algae in Brazil that is fully integrated and based on the same criteria and lexicon to define invasive species across all plant and animal taxa and habitats. We list 444 invasive non-native species: 254 animals, 188 plants and 2 algae. Some of the invasive species have been present in Brazil since the beginning of the European colonization in the 1500 s, but the majority of first records in Brazil were made in the last century, with copious first records after the year 2000. The list of invasive species presented here represents the most comprehensive attempt thus far to catalog all invasive non-native species at a continental-scale for a megadiverse country. Brazil has published a national strategy with the objective of improving mechanisms and partnerships for invasive non-native species prevention, early detection and rapid response. We believe that the current list of invasive species will provide technical and scientific support for the implementation of effective measures in the management of biological invasions.
