Alien species in Norway: Results from quantitative ecological impact assessments
Abstract 1 . Due to globalisation, trade and transport, the spread of alien species is increasing dramatically. Some alien species become ecologically harmful by threatening native biota. This can lead to irreversible changes in local biodiversity and ecosystem functioning, and, ultimately, to bioti...
