  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. Can the disappearance of the forest orchid Goodyera repens be linked to clearcutting? : a spatial analysis using citizen science data from southern Sweden.

    Master-uppsats, SLU/Southern Swedish Forest Research Centre

    Författare :Ines Diaz Garcia; [2024]
    Nyckelord :Goodyera repens; knärot; Artportalen; forestry; clearcut; citizen science; southern Sweden; conservation;

    Sammanfattning : Habitat transformation through forestry has an impact on boreal species in northern Europe. In Sweden, even-aged plantations with clearcut harvesting are forestry practices that affect the understory vegetation. This study focuses on the red-listed Goodyera repens, a rhizomatous evergreen orchid. LÄS MER

  4. 3. 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. 4. 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

  7. 5. The restoration period : a new era in forestry

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

    Författare :Ester Andersson; [2023]
    Nyckelord :historical forest management; past logging; restoration;

    Sammanfattning : In the last 200 years the boreal forests of Sweden have undergone a dramatic transformation. After a long history of high grading the largest trees foresters grew increasingly concerned about the state of logged over forests. The big question was how to regenerate and increase the productivity of sparse forests. LÄS MER
