  1. 1. 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

  3. 2. Plant-soil feedbacks in boreal tree species

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

    Författare :Kailey Tentis; [2023]
    Nyckelord :plant-soil feedback; plant economic spectrum; biotic feedback; abiotic feedback; sterilization-inoculation experiment; conspecifics and heterospecifics;

    Sammanfattning : Plant-soil feedback (PSF) is important for understanding how plants influence the composition and abundance of soil biota and nutrients and how this affects plant growth. The plant economic spectrum (PES) also plays a role. LÄS MER

  4. 3. Förekomst och spridning av hänglavar från äldre skogar till unga tidigare avverkade områden i Västerbottens inland

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

    Författare :Emma Maksimova; [2023]
    Nyckelord :Lichens; Dispersal; Picea abies; Pinus sylvestris; Epiphytic; Hair lichens; Alectoria; Bryoria; Usnea;

    Sammanfattning : The Swedish forestry and the use of clearcutting models has resulted in great losses of older forests in Sweden, resulting in several species being affected negatively. Hair lichens are important organisms that are providing several ecological functions in forest ecosystems and are declining due to being associated with older forests with high continuity. LÄS MER

  5. 4. The modern folkhem

    Master-uppsats, Lunds universitet/Industridesign

    Författare :Maritina Klaesson; [2023]
    Nyckelord :Arts and Architecture; Technology and Engineering;

    Sammanfattning : ”Most of Sweden’s surface is covered by forest, 68 percent is woodland; the built-up and landscaped land does not make up more than 3 percent of Sweden’s total land area. About 50% of the forest land is made of pine (Pinus sylvestris), making it the most common tree species in the country’s forests. LÄS MER

  7. 5. Scots pine (Pinus sylvestris L.) morphological variation in the Massif Central region, France. : A study of differences in traits between populations.

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

    Författare :Amanda Johansson; [2023]
    Nyckelord :;

    Sammanfattning : Scots Pine (P. sylvestris L.) has one of the largest distributions among trees in Eurasia. It is important both economically and ecologically, with a dominant role in forests ecosystems. LÄS MER
