  1. 1. 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

  3. 2. Trait variation in Lodgepole Pine : do populations differ in traits depending on if they are invasive or in their home range?

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

    Författare :Lisa Lindberg; [2021]
    Nyckelord :Invasive species; traits; introductions; native; Pinus contorta; Lodgepole pine;

    Sammanfattning : As a result of the global world we today live in, species are transported outside of their native range to new areas. Some of these species becomes invasive, which can cause a variety of negative effects. Traits are often thought to play an important role in invasion success. LÄS MER

  4. 3. Hur påverkas skogslevande myror av den introducerade contortatallen?

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

    Författare :Mattias Andreasson; David Karlsson; [2020]
    Nyckelord :Pinus sylvestris; Pinus contorta; tall; Formicidae; myror; biodiversitet; boreal; skog;

    Sammanfattning : I Sverige finns det intresse för nyintroducerade trädarter inom skogsbruket s.k. exoter. Exoterna kan påverka skogens biodiversitet negativt. LÄS MER

  5. 4. Reforestation in the far north : comparing effects of the native tree species Betula pubescens and the non-native Pinus contorta in Iceland

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

    Författare :Elin Fries; [2017]
    Nyckelord :Iceland; non-native tree species; understory vegetation; P. contorta; B. pubescens;

    Sammanfattning : The use of non-native tree species in forestry is both praised and questioned. Foresters have often promoted their use, mainly because of higher growth rates, resilience to pests and diseases and improved survival under harsh conditions. LÄS MER

  7. 5. Förutsättningar för naturhänsyn i bestånd med contortatall (Pinus contorta)

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

    Författare :Elisabet Ekblad; [2015]
    Nyckelord :Pinus contorta; naturhänsyn; naturvärde; biologisk mångfald; Forest Stewardship Council; svensk skogsvårdslagstiftning; environmental consideration; high conservation value; biodiversity; the Swedish Forestry Act;

    Sammanfattning : Det främmande trädslaget P. contorta (Pinus contorta) infördes storskaligt till Sverige på 1970-talet i syfte att motverka en befarad virkessvacka under 2000-talet. Idag finns uppskattningsvis 600 000 ha contortaskogar i Sverige och delar av dessa arealer närmar sig gallrings- och avvecklingsläge. LÄS MER
