2. 1. The threat from non indigenous species - ecosystem vulnerability, global distribution and co-occurrence with other major threats

   Author : Helena Berglund; Biodiversitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; threats; distribution range; isolation; endemism; invasions; invaders; vulnerability; non indigenous species; rarity; threatened species;

   Abstract : 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). READ MORE

6. 4. Global trade, food production and ecosystem support : Making the interactions visible

The general aim of this thesis was to explore the role of individual characteristics in the development of antisocial behaviour and alcohol problems. READ MORE
