  1. 1. Riparian plant biodiversity and community composition of ditches and straightened streams : identifying key environmental drivers in a boreal forest setting

    Master-uppsats, SLU/Dept. of Forest Ecology and Management

    Författare :Rasmus Staaf; [2024]
    Nyckelord :artificial waterways; riparian zone; novel ecosystems; ; forestry; ditch network maintenance; species richness; hill-diversity; drainage ditches; coarse woody debris; ditch cleaning; ecology;

    Sammanfattning : Modified ecosystems are typically seen as degraded and having no ecological value. In many cases, the modification of the ecosystem was done more than 100 years ago and may have had time to recover and become a refugia for species that were once more common in the landscape.

    Master-uppsats, Uppsala universitet/Institutionen för ekologi och genetik

    Författare :Gustaf Dahlstrand; [2021]
    Nyckelord :konnektivitet; fiskvandring; dammrivning; avsänkning; batymetri; elfiske; biotopkartering; HEC-RAS; hydraulisk modellering; fiskväg; vandringshinder;

    Sammanfattning : I Sverige finns i dagsläget närmare 10 000 dammar i våra vattendrag. Dammar som har varit en viktig del i den svenska historien men som nu utgör ett hot mot att uppsatta miljömål nås.

  4. 3. En giftfri konstgräsplan

    Kandidat-uppsats,

    Författare :Ville Nyström; Kajsa Odelgard; Clara Pierrou; Andreas Eriksson; Alexander Eriksson; [2017]
    Nyckelord :Artificial turf; granules; EPDM; R-EPDM; SBR; VOC; oral intake; health;

    Sammanfattning : EPDM and R-EPDM granules are used as infill on all of the artificial football fields in Uppsala. The aim of the study was to establish possible health risks related to the infill for players on artificial turf in Uppsala. Furthermore the aim was to investigate the possible ecotoxicological effect on surrounding waterways by the infill material. LÄS MER

    Nyckelord :Trichoptera; light attraction; artificial light; biodiversity; insects;

    Sammanfattning : Artificial light is an important and necessary part of our urban environment, but has become a threat to biodiversity. It can have substantial direct and indirect effects on populations of all kinds of organisms. LÄS MER
