Biological invasions are a main cause of biodiversity loss, prompting international agreements and national policies aimed at preventing and managing the introduction, establishment, spread, and impacts of alien species. However, whether these measures have effectively reduced invasions remains uncertain. In this study, we compared the absolute number of established alien species and changes in invasion rates, ...
Biological invasions are a major threat to global biodiversity with particularly strong implications for island biodiversity. Much research has been dedicated towards understanding historic and current changes in alien species distribution and impacts on islands and potential changes under future climate change. However, projections of how alien species richness and impacts on islands might develop in the futur...
