  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.

  3. 2. Hydraulic Modelling of Eurasian Beaver Structural Modifications: Implications for Evaluating their Contributions to Natural Flood Management in Scotland

    Master-uppsats, Lunds universitet/Avdelningen för Riskhantering och Samhällssäkerhet

    Författare :Maja Christina Pitcairn; [2023]
    Nyckelord :Beaver reintroduction; Scotland; Flood risk; Natural flood management; Hydraulic modelling.; Technology and Engineering;

    Sammanfattning : The concurrent climate and biodiversity crises in Scotland necessitate the exploration of ecosystem-based adaptation to simultaneously address increased flood risk and the loss of native species. This research investigated the contributions of Eurasian beaver reintroductions to natural flood management in Scotland. LÄS MER

  4. 3. Meadowscape : Bring health to ecological systems through actions in the agricultural landscape

    Uppsats för yrkesexamina på avancerad nivå, Umeå universitet/Arkitekthögskolan vid Umeå universitet

    Författare :Anna Östlund; [2023]
    Nyckelord :Actor-network theory; landscape ecology; agriculture; artifacts; patterns;

    Sammanfattning : The physical landscape is a patchwork of different physical and immaterial structures and networks built up through time, where nature and culture cooperate in processes of shaping the landscape. Since the first settlers in Sweden the grass meadow has taken a central part in the agricultural practices, but today little of this landscape remains. LÄS MER

  5. 4. Demographic equilibrium modelling of single tree selection stands in Siljansfors : judging the sustainability of single tree selection systems in Sweden

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

    Författare :Ludwig Olofsson; [2023]
    Nyckelord :CCF; continuous cover forestry; single tree selection; equilibrium models; forestry;

    Sammanfattning : Lately debates have occurred questioning the rotation system, which is the most used silvicultural system in Sweden. Continuous cover forestry (CCF) has therefore been suggested as an alternative management method, due to its environmental benefits such as increased biodiversity and higher resilience against extreme weather which is important with the current climate change.

  7. 5. Shortening the chains : social relations and dynamics of production in Uppland's alternative food networks

    Master-uppsats, SLU/Dept. of Urban and Rural Development

    Författare :Eleni Katsika; [2023]
    Nyckelord :alternative food networks; food commoning; dynamics of production; political ecology; social relations; Sweden;

    Sammanfattning : Current global food systems are characterised by a highly concentrated capitalist market where food is treated as a globalised hyper commodity and small-scale farmers are pushed into the side-line. The need for the transformation of that food system is urgent and acknowledged worldwide. LÄS MER
