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

    University essay from Göteborgs universitet / Institutionen för biologi och miljövetenskap

    Author : Linnéa Eriksson; [2023-04-20]
    Keywords : 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;

    Abstract : 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. READ MORE

  3. 2. Sortase A coupling of the recombinant partial silk proteins 4Rep-Srt and G-/G5-CT to understand the structure of silk fiber

    University essay from KTH/Proteinvetenskap

    Author : Ellen Adlerz; [2023]
    Keywords : 4RepCT; 4Rep-Srt; G- G5-CT; Sortase A coupling; recombinant silk protein; 4RepCT; 4Rep-Srt; G- G5-CT; Sortase A-koppling; rekombinant silkesprotein;

    Abstract : Spindelsilke är ett intressant material på grund av dess biokompatibilitet och därav användning som biomaterial. Det är jämförbart med konstgjorda material när det gäller styrka och elasticitet, och i kombination med biokompatibiliteten, är spindelsilke eftertraktat inom det medicinska området. READ MORE

  4. 3. N2 fixation of three legume species in an agroforestry system

    University essay from SLU/Dept. of Soil and Environment

    Author : Hsiang-Ju Fan; [2023]
    Keywords : nitrogen; dinitrogen fixation; legumes; groundnut; stylo; pinto peanut; understorey crop;

    Abstract : Due to the strong soil erosion caused by agricultural activities and sloping landscape, agroforestry has been introduced as a potentially sustainable cropping practice in the mountainous NW Vietnam. Using legumes as understorey crops in these systems has a potential to limit erosion and smother weeds, as well as provide additional nitrogen (N) to the system. READ MORE

  5. 4. Forest regeneration and edge effects : an ecophysiological analysis after gap-cutting

    University essay from SLU/Dept. of Forest Ecology and Management

    Author : Tyra Tornberg; [2023]
    Keywords : Regeneration; Edge effects; Edge zone; Continuous cover forestry; Gap-cutting; Isotope analysis; 15N; Nitrogen; Carbon;

    Abstract : As continuous cover forestry is an ongoing topic in todays forest debate, questions are raised about eventual issues connected to the management. It is known that seedling performance can be poor near the edge of harvested areas, and around retained trees. This is a critical issue in transitioning toward continuous cover forestry. READ MORE

  6. 5. Explicit consideration of microbes in quantification of gross N rates based on N-tracing model

    University essay from Göteborgs universitet/Institutionen för geovetenskaper

    Author : Tsai-wei Tang; [2022-01-26]
    Keywords : N-tracing model; microbial biomass; gross N quantification; organic N; mineralization; immobilization;

    Abstract : When studying the nitrogen cycle in soils, the principle of 15N isotope dilution and enrichment is commonly used to measure gross N transformation rates. The measuring data of both organic and inorganic nitrogen substrates are therefore be analysed by Ntrace model. READ MORE
