  1. 1. Demographic equilibrium modelling of single tree selection stands in Siljansfors : judging the sustainability of single tree selection systems in Sweden

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

    Author : Ludwig Olofsson; [2023]
    Keywords : CCF; continuous cover forestry; single tree selection; equilibrium models; forestry;

    Abstract : 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. The Dynamics of Air Pollution, Socio-Economic Status and Mortality Rate: Panel Study Evidence from Sweden

    University essay from Linnéuniversitetet/Institutionen för nationalekonomi och statistik (NS)

    Author : Uzma Humayun; [2023]
    Keywords : ;

    Abstract : This study investigated the relationship between the mortality rate and air pollution, as well as socioeconomic factors such as education, socioeconomic status, smoking behavior, and unemployment in Sweden using regional data on county level from 2005 to 2021. The study adopted Environmental Justice Theory as the theoretical framework and used fixed effects model to control for unobserved heterogeneity. READ MORE

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

    University essay from Uppsala universitet/Institutionen för medicinsk biokemi och mikrobiologi

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

    Abstract : 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. READ MORE

  5. 4. Population dynamics of the spruce bark beetle Ips typographus in forest conservation areas and the interaction with biodiversity and natural enemies

    University essay from SLU/Dept. of Ecology

    Author : Evelina Andersson; [2023]
    Keywords : spruce bark beetle; population dynamics; conservation areas; biodiversity; natural enemies; species richness; managed forests; woodland key-habitats; nature reserves;

    Abstract : Biodiversity is rapidly decreasing and in need of more conservation efforts. However, the tree-killing European spruce bark beetle, Ips typographus (L.), has made forest conservation controversial by affecting conservation areas and possibly adjoining managed forests, yet is still a keystone species leaving decaying wood promoting biodiversity.

  6. 5. Investigating the influence of the tidal regime on harbour porpoise Phocoena phocoena distribution in Mount’s Bay, Cornwall

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Duncan Jones; [2023]
    Keywords : Geography; Geographical Information Systems; GIS; Habitat Modelling; Harbour Porpoise; MaxEnt; Tidal Processes; Conservation; Earth and Environmental Sciences;

    Abstract : Investigating the influence of the tidal regime on harbour porpoise Phocoena phocoena distribution in Mount’s Bay, Cornwall Abstract Unintentional by-catch in fishing gear is a significant cause of mortality of harbour porpoises in UK waters. Understanding the spatial distribution of harbour porpoises at fine scales and how this changes over time is essential when trying to understand where these lethal interactions might occur. READ MORE
