  5. 3. 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. Chemical composition of summertime High Arctic aerosols

    Author : Karolina Siegel; Claudia Mohr; Annica Ekman; Ilona Riipinen; Lise Lotte Sørensen; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; aerosol; chemical composition; Arctic climate; atmosfärvetenskap och oceanografi; Atmospheric Sciences and Oceanography;

    Abstract : This thesis presents new insights into the chemical composition of semi-volatile compounds in aerosol samples collected in the central Arctic Ocean close to the North Pole in September 2018. The central Arctic Ocean is an inaccessible location due to the lack of land areas along with heavy pack ice conditions. READ MORE

  7. 5. Small biotopes: Landscape and management effects on pollinators

    Author : Annika Söderman; Biodiversitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Agri-environmnetal scheme; management; agriculture; landscape complexity; heterogeneity; landscape scale; mall biotopes; field boundaries; pollinating insects; pollination; bumblebees; solitary bees; hoverflies;

    Abstract : The intensification of agriculture during the second half of the twentieth century, has caused sever declines of farmland biodiversity, where loss of semi-natural habitats is one of the major drivers. To halt further loss of habitat and biodiversity, agri-environmental schemes (AES) are used to compensate farmers to use methods less harmful to the environment. READ MORE
