  1. 1. 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.

  3. 2. Characterization of Antigenic Properties of Two Immunogenic Proteins of Streptococcus pneumoniae 

    Master-uppsats, Uppsala universitet/Institutionen för medicinsk biokemi och mikrobiologi

    Författare :Mawj Jasimalsalih; [2023]
    Nyckelord :Immunogenic Proteins; PrsA; MalX; Membrane Vesicles; Protein Properties; Streptococcus pneumoniae virulence factors;

    Sammanfattning : The bacterium Streptococcus pneumoniae (pneumococcus), is considered to be a leading cause of morbidity and mortality globally, particularly in infants and the elderly. It is one of the most frequent causes of respiratory tract infections, which sporadically have the potential to develop into serious invasive symptoms including sepsis and meningitis. LÄS MER

  4. 3. Exploring the factors affecting tree establishment after wildfire in a boreal forest in Sweden

    Master-uppsats, Uppsala universitet/Institutionen för biologisk grundutbildning

    Författare :Robert Pim; [2023]
    Nyckelord :tree regeneration; tree establishment; wildfire; boreal forests; disturbance; sapling regeneration; generalized linear mixed models;

    Sammanfattning : The factors affecting tree establishment in boreal forests after fire will help determine the community composition of the regenerating forest. These may have large consequences on the community dynamics for years after the fire disturbance. LÄS MER

  5. 4. Estimation of Site-Specific Biomass and Leaf Area Index in a Young Scots pine Stand in Southern Sweden

    Master-uppsats, SLU/Southern Swedish Forest Research Centre

    Författare :Olamide Michael Adu; [2023]
    Nyckelord :Scots pine; Biomass estimation; Leaf area index; Model validation; Site-specific models;

    Sammanfattning : Accurate biomass and leaf area index (LAI) estimation are crucial for understanding forest productivity and carbon dynamics. Models are crucial to estimating forest biomass and LAI. This study aimed to estimate site-specific aboveground biomass and LAI in a young Scots pine stand in southern Sweden. LÄS MER

  7. 5. Growth of Silver birch (Betula pendula) & Downy birch (Betula pubescens) established in four different initial densities on one site in central Sweden

    Master-uppsats, SLU/Southern Swedish Forest Research Centre

    Författare :Edvards Romans; [2023]
    Nyckelord :Betula pendula; Betula pubescens; plantation; initial spacing; simulation; management;

    Sammanfattning : Nowadays, there is an increased demand for timber resources and more sustainable forest management, starting from the establishment phase of the forest, e.g., planting. Depending on the management goals, number of seedlings planted and thus initial spacing can be adjusted in order not to waste resources. LÄS MER
