  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. Implementation of Level of Development for BIM Collaboration in Timber Building Subsystems Design: A Case Study of I-Joist Construction Elements

    Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

    Författare :Isabell Gustafsson; [2024]
    Nyckelord :BIM; I-Joist; LOD; Level of Development; Timber Building Subsystems;

    Sammanfattning : Due to time, cost, and environmental challenges, wood has become a more common building material even for more complex buildings. Implementing the concept of Level of Development (LOD) on timber structures could provide a tool for BIM collaboration that may save cost and time, and in the early stages mediate wood as an available building material.

  4. 3. Vedlevande skalbaggar 10–20 år efter brand i tallskog : en jämförelse mellan hällmark och produktiv mark

    Kandidat-uppsats, SLU/Dept. of Wildlife, Fish and Environmental Studies

    Författare :KajsaLisa Olsson; [2024]
    Nyckelord :Tallimpediment; biologisk mångfald; vedlevande skalbaggar; naturvårdsbränning; Pinus sylvestris;

    Sammanfattning : The Swedish boreal forests have changed drastically in the last century. Intensive forestry with clear-cuttings and fire-prevention, cause a lack in dead wood diversity and volume. The current research on forests mainly focuses on productive forests and there is a knowledge gap regarding the importance of low-productive forest for biodiversity. LÄS MER

  5. 4. Hägnaders roll i det historiska kulturlandskapet - En studie av hägnaders utveckling och funktion på den bohuslänska ön Orust

    Kandidat-uppsats, Göteborgs universitet/Institutionen för kulturvård

    Författare :Julia Olsson; [2023-05-03]
    Nyckelord :Landscape heritage; historical maps; fence; photographs; Orust; Swedish west coast; Landskapsvård; historiska kartor; hägnad; gärdesgård; fotografi; Bohuslän;

    Sammanfattning : Over the years, fences have served a variety of purposes. They have also been built in different types of materials such as stone, wood, peat and soil. Depending on the material used, there are a varying number of fences left today. LÄS MER

  7. 5. Analys av föda för vitryggig hackspett och rödlistade vedlevande skalbaggar : utvärdering av tre olika behandlingar

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

    Författare :Emma Mattsson; Lena Ostermann; [2023]
    Nyckelord :Vitryggig hackspett; vedlevande skalbaggar; paraplyart; rödlista; biologisk mångfald; död ved; restaurering;

    Sammanfattning : Den vitryggiga hackspetten har sedan 1950-talet blivit en sällsynt art i det svenska landskapet. Nedgången beror främst på det moderna skogsbruket där barrskog till stor del har ersatt blandbestånd och gammal lövskog. LÄS MER
