  1. 21. Exploring the factors affecting tree establishment after wildfire in a boreal forest in Sweden

    Master-uppsats, Uppsala universitet/Institutionen för biologisk grundutbildning

    Författare :Robert Pim; [2023]
    Nyckelord :tree regeneration; tree establishment; wildfire; boreal forests; disturbance; sapling regeneration; generalized linear mixed models;

    Sammanfattning : The factors affecting tree establishment in boreal forests after fire will help determine the community composition of the regenerating forest. These may have large consequences on the community dynamics for years after the fire disturbance. LÄS MER

  3. 22. Olika skötselalternativs påverkan på kolinlagringen i boreala skogar : jämförelse mellan fyra olika skötselalternativ som används i svenskt skogsbruk

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

    Författare :Cornelia Samuelsson; Johan Andersson; [2023]
    Nyckelord :kolbalans; klimatmål; hyggesfritt; trakthyggesbruk; Heureka;

    Sammanfattning : Politiken är tydlig i vad som måste hända för att motverka en global klimatkris; utsläppen måste minska och inlagringen måste öka. De antagna målen är satta i etapper där det sista innebär ett nettonollutsläpp till 2045, och efter det ska Sverige vara en kolsänka. LÄS MER

  4. 23. How is carbon stored in boreal forest soils? - A method development which investigates at what protein concentration ferrihydrite and goethite are saturated.

    Kandidat-uppsats, Lunds universitet/Centrum för miljö- och klimatvetenskap (CEC)

    Författare :Louise Berild; [2023]
    Nyckelord :Soil nitrogen; soil carbon; boreal forest; ectomycorrhizal fungi; decomposition; adsorption; ferrihydrite; goethite; Earth and Environmental Sciences;

    Sammanfattning : Boreal forests store the majority of their carbon in the soil and play an important role in the global carbon cycle. However, the mechanisms that control carbon storage in boreal soils are not well understood. LÄS MER

  5. 24. 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.

  7. 25. Soil Carbon Stocks in Old Growth Forest : Drivers of variability in soil organic carbon stocks in old growth boreal forests

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

    Författare :Elis Ingvarsson; [2023]
    Nyckelord :old growth forest; boreal; soil organic carbon stocks; climate gradient;

    Sammanfattning : Soil organic carbon (SOC) is the largest carbon pool in terrestrial ecosystems, which plays an important role in climate change by regulating atmospheric carbon dioxide. Sweden’s forest management has led to a decrease in old growth forests. This change in land use can affect SOC levels in these forests. LÄS MER
