  1. 11. Forest regeneration and edge effects : an ecophysiological analysis after gap-cutting

    Master-uppsats, SLU/Dept. of Forest Ecology and Management

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

    Sammanfattning : 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. LÄS MER

  3. 12. Hänglavsförekomst i olika kantzoner : En studie i skogarna kring Fällfors, Skellefteå kommun

    Kandidat-uppsats, Umeå universitet/Institutionen för ekologi, miljö och geovetenskap

    Författare :Sara Persson; [2023]
    Nyckelord :Epiphytic lichen; Edge effects; Forest fragmentation; Alectoria; Bryoria; Usnea; Canopy opening;

    Sammanfattning : Epiphytic lichens require an even climate (no major changes in temperature and humidity) and continuity in the forest to thrive and grow, but forestry and its clear cutting destroys these habitats. The consequences are particularly serious when it occurs in forests with a high degree of management continuity. LÄS MER

  4. 13. Riparian vegetation ecology : an observational study into the effects of forest management on understory vegetation communities along boreal headwaters

    Master-uppsats, SLU/Dept. of Forest Ecology and Management

    Författare :Ruben Jonathan Baan Hofman; [2023]
    Nyckelord :riparian forest; forest management; understory vegetation; headwater streams; community ecology;

    Sammanfattning : Riparian forests along headwater streams have long been recognized for their role as an interface between the terrestrial and aquatic ecosystem. The over- and understory vegetation performs essential ecological and biochemical functions, which are important for stream functions. LÄS MER

  5. 14. Evaluation of the variation in albedo over snow-covered forest in Northern Sweden and Finland

    Master-uppsats, Göteborgs universitet/Institutionen för geovetenskaper

    Författare :Klara Hugosson; [2022-05-20]
    Nyckelord :;

    Sammanfattning : The effect of albedo variability induced by meteorological parameters in snow-covered forested areas at local scale is poorly known. Few meteorological stations measure albedo, even though the effect on albedo caused by land use changes is well known. LÄS MER

  7. 15. Architecture and the spatial fluidity of daylight

    Magister-uppsats, KTH/Ljusdesign

    Författare :Yun Long; [2022]
    Nyckelord :KTH; Stockholm; Architecture; Lighting design;

    Sammanfattning : “In the life of man, the house thrusts aside contingencies, its councils of continuity are unceasing.” (Gaston Bachelard, 1957) More than 20 cities have more than 10 millions inhabitants nowadays, and in the past few years, people have spent more time in residences (Hesam Kamalipour, 2020) finding the method to optimize the daylight without compromising spatial characteristics and human well-being is a task for architects and engineers.
