3. The threat from non indigenous species - ecosystem vulnerability, global distribution and co-occurrence with other major threats
Sammanfattning : We live in a globalised world where people and goods travel large distances. Various species are brought along on these journeys, intentionally or as hitchhikers. Some of these species establish populations in regions to which they could not have spread without human assistance, and where they are considered to be non indigenous species (NIS). LÄS MER
