Biological invasions have steadily increased over recent centuries. However, we still lack a clear expectation about future trends in alien species numbers. In particular, we do not know whether alien species will continue to accumulate in regional floras and faunas, or whether the pace of accumulation will decrease due to the depletion of native source pools. Here, we apply a new model to...

Biological invasions are a global consequence of an increasingly connected world and the rise in human population size. The numbers of invasive alien species – the subset of alien species that spread widely in areas where they are not native, affecting the environment or human livelihoods – are increasing. Synergies with other global changes are exacerbating current invasions and...

According to the most recent (2005) compendium on the history of the European hedgehog (Erinaceus europaeus) in New Zealand, this small insectivorous mammal was first brought from Europe to the South Island in the 19th century. This introduction has been presumed to be the source of hedgehogs that subsequently spread to the North Island. This view was informed by the absence of hedgehogs in...
