  1. 1. Effect of stand age on soil respiration in managed vs unmanaged Scots pine stands

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

    Författare :Richard Engholm; [2024]
    Nyckelord :chronosequence; soil respiration; total respiration; autotrophic respiration; heterotrophic respiration; forestry;

    Sammanfattning : How the forests in Sweden and around the world have been, and are still today, managed is a hot debate. The rotation forestry that is commonly used in Sweden has been the focus of debate regarding whether it is a sustainable management method, and whether it should be changed. LÄS MER

  3. 2. Influence of different carbon sources on methane fluxes in sediments of eelgrass beds and unvegetated areas: a case study on the Swedish west coast

    Kandidat-uppsats, Göteborgs universitet / Institutionen för biologi och miljövetenskap; Göteborgs universitet / Institutionen för biologi och miljövetenskap

    Författare :Hampus Holmberg; [2023-06-22]
    Nyckelord :;

    Sammanfattning : One of the best ways to mitigate climate change is through natural carbon sequestration. An efficient way to mitigate climate change is through carbon sequestration from coastal habitats. LÄS MER

  4. 3. Evaluating a new hydraulic implementation in LPJ-GUESS for three sites in north Europe

    Master-uppsats, Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Författare :Carl Holmquist; [2023]
    Nyckelord :Physical Geography and Ecosystem analysis; LPJ-GUESS; drought; sensitivity analysis; evapotranspiration; gross primary production; hydraulic parameters; boreal forest.; Earth and Environmental Sciences;

    Sammanfattning : Drought is projected to increase in frequency and intensity and impacts trees with increased water stress and increased mortality rate. Water stresses can cause hydraulic failure-related mortality or carbon starvation due to tree species having different strategies to deal with water stresses. LÄS MER

  5. 4. Towards climate optimised riparian buffer zones in boreal forests

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

    Författare :Alice Falk; [2022]
    Nyckelord :Forestry; Biogeochemical hotspots; Carbon dioxide; Methane;

    Sammanfattning : Boreal forests have the potential to mitigate the increased concentrations of greenhouse gases (GHGs) in the atmosphere. However, forestry alters the soil biogeochemical processes which can cause an increase in GHG emissions from nearby water bodies, soil and vegetation. LÄS MER

  7. 5. Effects of vegetation and nutrients on methanotroph abundance and methane emissions from constructed wetlands

    Master-uppsats, SLU/Dept. of Aquatic Sciences and Assessment

    Författare :Klara Yngve; [2022]
    Nyckelord :Diffusive flux; Ebullition; Dissolved CH4; CH4 oxidation; Phosphorous;

    Sammanfattning : Agriculture is the largest anthropogenic source of nitrogen and phosphorous (P) leakage to Swedish coastal seas, causing eutrophication which threatens marine ecosystems. Constructing wetlands is one way to improve nutrient retention in the modern agricultural landscape. However, constructed wetlands can emit substantial amounts of methane (CH4). LÄS MER
