  1. 11. Insect diversity on clearcuts in boreal forest landscapes

    Författare :Diana Rubene; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Sammanfattning : Intensive management and loss of natural disturbance dynamics in boreal forests leads to habitat loss and degradation for forest dwelling species. As a consequence, many species have become threatened, especially those dependent on dead wood. LÄS MER

  3. 12. The forgotten forest : on thinning, retention, and biodiversity in the boreal forest

    Författare :Julian Klein; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Fennoscandia has had a long history of intensive forest management. It can therefore be regarded a trial zone for other boreal regions which are still largely unaffected by forestry. In Fennoscandia, forestry has resulted in many threatened species and methods that maintain biodiversity have therefore been called for. LÄS MER

  4. 13. Improving boreal forest regeneration in a variable climate

    Författare :Bodil Häggström; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Sammanfattning : Regeneration of boreal forests in Sweden mainly involves planting Scots pine (Pinus sylvestris L.) and Norway spruce (Picea abies (L.) Karst.) seedlings on clear-cut areas, although there is an increasing interest in planting broadleaves and in applying continuous cover forestry (CCF). LÄS MER

  5. 14. Cyanobacteria in symbiosis with boreal forest feathermosses : from genome evolution and gene regulation to impact on the ecosystem

    Författare :Denis Warshan; Ulla Rasmussen; Elke Dittmann; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Cyanobacteria; Feathermosses; Symbiosis; Boreal forest; Gene flow; Proteogenomic; Transcriptomic; Community structure and composition; Dinitrogen fixation; Plant Physiology; växtfysiologi;

    Sammanfattning : Among dinitrogen (N2)-fixing some cyanobacteria can establish symbiosis with a broad range of host plants from all plant lineages including bryophytes, ferns, gymnosperms, and angiosperms. In the boreal forests, the symbiosis between epiphytic cyanobacteria and feathermosses Hylocomium splendens and Pleurozium schreberi is ecologically important. LÄS MER

  7. 15. Carbon Balance Implications of Forest Biomass Production Potential

    Författare :Bishnu Chandra Poudel; Inga Carlman; Johan Bergh; Thomas Lundmark; Roger Sathre; Mittuniversitetet; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; forest management; silviculture; clear-cut forestry; continuous-cover forestry; substitution; total carbon; climate benefit; climate change; Forestry and Wood Technology; Skog och träteknik;

    Sammanfattning : Forests in boreal and temperate forest-ecosystems have importance for carbonbalance since they sequester large amount of atmospheric carbon by uptake ofcarbon-dioxide during photosynthesis, and transfer and store carbon in the forestecosystem. Forest material can be used for bio-fuel purposes and substitute fossilfuels, and supply wood products, which can replace carbon-and-energy-intensivematerials. LÄS MER
