Although there is wide consensus thatbiodiversity is threatened worldwide by human activities,the role that alien invasive species (AIS) play in this processis controversial. Many reports have addressed thisissue, but their conclusions differ widely. Disagreementsare partly due to the fact that drivers of species declinesand extinctions are multiple and concurrent, and unevenlydistributed among taxa and geographic regions, but con-icting interpretations of the same sources of informationseem to play an important role as well. These discrepanciesunderscore our poor understanding of the role of AIS inthe declines and extinctions of native organisms, hinderingdecisions associated with resource allocation for managementactions.
