  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. 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

  3. 3. Comparison of Gap-Cutting and Clear-cutting Management and Their Ecosystem Services : a Simulation Study

    Master-uppsats, SLU/Southern Swedish Forest Research Centre

    Författare :Mary Motunrayo Ogunleye; [2023]
    Nyckelord :ecosystem services; gap-cut management; Scots pine; clear-cut; forest management;

    Sammanfattning : Forests as a natural ecosystem provide many functions and services that contribute to livelihood. Moreover, to provide multifaceted services, the forest management strategy employed is vital in establishing desired ecosystem services. LÄS MER

  4. 4. Beetle Diversity – Land Sparing or Land Sharing? : the effects of timber extraction and restoration method on saproxylic beetle assemblages in mature managed pine forests

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

    Författare :Ella Amnéus; Sebastian Hjelström; [2023]
    Nyckelord :Saproxylic Beetles; Ecological Restoration; Deadwood; Biodiversity; Boreal Forest; Fire Ecology; Land-sparing; Land-sharing; Conservation Management;

    Sammanfattning : The impoverishment of saproxylic beetle communities is a growing concern for management of boreal forest biodiversity. Past research has found active restoration methods, such as creating deadwood and conducting prescribed burnings, to have a short-term positive effect on the species richness and compositional diversity of saproxylic beetle assemblages.

  5. 5. Beware of your neighbour : the effects of intraspecific interactions and CO2-level on the plant growth of two Barley cultivars

    Kandidat-uppsats, SLU/Dept. of Plant Protection Biology

    Författare :Nadja Nyberg; [2023]
    Nyckelord :Barley; Salome; Fairytale; cultivar mixture; pure stand; intraspecific competition; plant-plant interactions; competitive ability; elevated CO2;

    Sammanfattning : Plants have evolved several ways to sense what is going on around them. They can detect possible competitors by picking up on airborne Volatile Compounds emitted from neighbouring plants. The cues can induce growth responses that enhances the competitive ability of the receiver. LÄS MER
