  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. Greenhouse gas emissions from peat soil thawing in spring : a comparison between fertilized and unfertilized soil

    Master-uppsats, SLU/Dept. of Soil and Environment

    Författare :Fanny Otterlin Karlsson; [2024]
    Nyckelord :agricultural soil; carbon dioxide; freeze-thaw cycles; nitrous oxide; soil temperature; water content;

    Sammanfattning : Peat soils drained for agriculture and forestry contribute to a significant amount of greenhouse gas emissions. Nitrous oxide is a greenhouse gas with high warming potential and agriculture in general accounts for about 70 % of nitrous oxide emissions. LÄS MER
