  1. 1. Effects of organic matter depletion on fungal communities in a reconstructed boreal forest podzol system

    Master-uppsats, SLU/Dept. of Forest Mycology and Plant Pathology

    Författare :Katharine Alice King; [2020]
    Nyckelord :ectomycorrhizal fungi; fungal community structure; fungal diversity; high throughput sequencing; podzol; soil horizons;

    Sammanfattning : The boreal forest biome serves as a valuable resource, both as a source of wood, pulp and biofuel, and as a sink of atmospheric carbon (C). A large proportion of C is sequestered to the soil of the boreal biome, however belowground processes are still poorly understood. LÄS MER

  3. 2. Analyzing microplastics in soils : Evaluating canola oil extractions

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

    Författare :Anna Bottone; [2019]
    Nyckelord :Microplastics; extraction recovery; OEP method; organic-rich soils;

    Sammanfattning : Small fragments of artificial polymers (microplastics, MPs) has been reported for multiple environmental matrices from our planet. The omnipresent existence of these microplastics even in remote polar areas have raised concern about their potential environmental impacts and created a need for effective and standardized analytical methods targeting their detection in environmental samples.

  4. 3. Microbial communities in a boreal forest podzol profile and responses to the presence of Pinus sylvestris seedling roots

    Magister-uppsats, SLU/Dept. of Forest Mycology and Plant Pathology

    Författare :Johanna Jernberg; [2013]
    Nyckelord :Archaea; Bacteria; Boreal forest; DGGE; Fungi;

    Sammanfattning : The boreal biome consists of coniferous forests that cover much of the northern hemisphere, and constitute an important natural resource for the forest industry, but has also gained attention in the light of global warming in acting as potential sinks of atmospheric carbon dioxide. Both forest production and carbon sequestration are closely connected to the activities of soil microorganisms, which play major roles in nutrient cycling and decomposition of plant biomass. LÄS MER

  5. 4. The Effect of Parent Material on Ectomycorrhizal Community Composition and Diversity

    Master-uppsats, Lunds universitet/Examensarbeten i biologi

    Författare :Abdallah Awad; [2012]
    Nyckelord :ectomycorrhizal fungi; granite; serpentinite; amphipolite; community composition; diversity; organic horizon; mineral horizon; Biology and Life Sciences;

    Sammanfattning : Abstract Nutrient availability is one of the most important components of soil chemistry, and has Been shown to strongly impact ectomycorrhizal community composition and diversity. Phosphorous, magnesium, and potassium are important macronutrients for plant growth. LÄS MER

  7. 5. Markbehandling på boreal skogsmark med fokus på markberedning : en litteraturöversikt

    L3-uppsats, SLU/Dept. of Silviculture

    Författare :Eric Lammi; [2006]
    Nyckelord :markbehandling; markberedning; sådd; naturlig föryngring; hyggesbränning; nyrisplantering;

    Sammanfattning : Syftet med föreliggande arbete är att utreda några markbehandlingsmetoders för och nackdelar, samt när och var de bör användas. De markbehandlingsmetoder som behandlas är plöjning, högläggning, harvning, fläckmarkberedning, inversmarkberedning, ångbehandling, mikropreparering, nedmyllning av frön samt grönrisplantering.
