  1. 1. Can precommercial thinning be used to create more diversity after planting spruce?

    Master-uppsats, SLU/Southern Swedish Forest Research Centre

    Författare :Astrid Bygge; [2024]
    Nyckelord :Forestry; pre-commercial; stand structure; heterogeneity; silviculture; mixed forests; monoculture; Picea abies; Betula spp.;

    Sammanfattning : Mixed forests will harbour other ecosystem services than a planted coniferous monoculture. This study used early results from a long-term experiment to examine if different precommercial thinning treatments can be used to increase diversity in planted stands of Norway spruce (Picea abies) mixed with high densities of natural regeneration of birch (Betula spp. LÄS MER

  2. 2. PERCEPTION OF URBAN TREES AND THEIR ECOSYSTEM SERVICES

    Master-uppsats, Göteborgs universitet / Institutionen för biologi och miljövetenskap

    Författare :Emma Dalros Sköld; [2023-08-03]
    Nyckelord :perceptions; tree preferences; urban trees; ecosystem services;

    Sammanfattning : Global urbanization is one of the most wide-ranging, irreversible, and rapid land-use changes in modern history. Natural elements, such as trees, should be incorporated into cities to produce sustainable urban environments. LÄS MER

  3. 3. Norrbacka 1 : den glömda trädgården

    Kandidat-uppsats, Göteborgs universitet/Institutionen för kulturvård

    Författare :Victoria Palm; [2023-05-03]
    Nyckelord :cultural history; inventory; valuation; garden illustration; garden; kulturhistoria; inventering; värdering; trädgårdsillustation; trädgård;

    Sammanfattning : The left garden of Norrbacka 1, today Domprostegården 5:1, is an interesting place where plants of older varieties may be found. It´s important that places like this will be noticed so the society does not miss out on historical knowledge and plants that can matter to maintain biodiversity. LÄS MER

  4. 4. Trends in mountain birch seed abundance and its relation to temperature and moth abundance: a ten-year study from Swedish Lapland

    Kandidat-uppsats, Göteborgs universitet / Instiutionen för biologi och miljövetenskap

    Författare :Frida Gustafsson; [2023-02-09]
    Nyckelord :Betula pubescens; climate change; seed production; Epirrita autumnata; Operophtera brumata; subarctic ecology; folivory; larval abundance;

    Sammanfattning : Boreal forest is the world’s largest terrestrial biome. Being one of the most ubiquitous and coldtolerant tree species in Sweden, the mountain birch forms a unique deciduous treeline and marks the forest-tundra ecotone. LÄS MER

  5. 5. 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
