  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. Impact of nitrogen availability and nitrogen structural composition on fungal enzymatic activity and growth : how nutrient availability governs response and development of three saprotrophic Basidiomycetes

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

    Författare :Bella Strid; [2024]
    Nyckelord :nitrogen; tannins; condensed tannins; MnP; manganese peroxidase; peptidase; saprotrophic basidiomycetes;

    Sammanfattning : Fungi excrete a wide variety of extracellular enzymes to scavenge for nutrients, such as the often scarce yet essential nutrient nitrogen. All fungi produce highly specialized hydrolytic enzymes, e.g. peptidases, that depolymerize organic molecules. LÄS MER

  4. 3. SOIL GROSS NITROGEN MINERALISATION AND FOREST GROWTH IN FOUR HEMIBOREAL FOREST STANDS IN SOUTHWEST SWEDEN

    Master-uppsats, Göteborgs universitet / Institutionen för biologi och miljövetenskap

    Författare :Linnéa Eriksson; [2023-04-20]
    Nyckelord :soil C:N; forest production; 15N isotope dilution; gross N mineralisation; ammonium; soil carbon; soil nitrogen; root exudates; stoichiometric decomposition; boreal forests; priming; microbial C limitation;

    Sammanfattning : Boreal and temperate forests together make up the largest terrestrial net C sink in the world. They take up carbon dioxide (CO2) from the atmosphere and store it in plant biomass and soil as they grow, making them crucial in mitigating global climate change. LÄS MER

  5. 4. Effects of tillage and straw treatments on earthworm abundance : study in two Swedish long-term field trials

    Uppsats för yrkesexamina på avancerad nivå, SLU/Dept. of Soil and Environment

    Författare :Fredrik Ahlberg; [2023]
    Nyckelord :anecic; conventional tillage; endogeic; no-tillage; reduced tillage;

    Sammanfattning : Earthworms have several functions in the soil, for instance redistribution of organic matter and enhancing plant available nutrients. Earthworms are divided into three ecological groups, with different functions in the soil. The groups are: anecic, endogeic and epigeic. LÄS MER

  7. 5. En hållbart intensifierad slåttervall med vitklöver : en litteratursammanställning

    Kandidat-uppsats, SLU/Dept. of Crop Production Ecology

    Författare :Johanna Forss; [2023]
    Nyckelord :etablering; kväve; skördesystem; Trifolium repens; vall; vitklöver;

    Sammanfattning : Fördelarna med att inkludera vall i växtföljden är många, till exempel kolinlagring, markförbättrande egenskaper och ogräsbekämpning. Intresset för odling av vall ökar när det finns fler avsättningsmöjligheter och ses som ett medel för att uppnå en hållbar intensifiering av odlingssystemet. LÄS MER
