    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Coarse woody debris; Dead wood; Dendrochronology; Fire history; Forest conservation; Forest structure; Log; Meta-analysis; Pine heath forest; Prescribed burning; Saproxylic fungi; Saproxylic beetles; Snag; Wood-inhabiting fungi; Aktiv skötselmetod; Bevarandebiologi; Brandhistorik; Dendrokronologi; Död ved; Hällmarkstallskog; Lågproduktiv skog; Meta-analys; Naturvård; Naturvårdsbrand; Skogsstruktur; Solbelyst död ved; Stock; Torraka; Vedlevande svamp; Vedlevande insekter; Åldersstruktur;

    Sammanfattning : In today´s intensively managed landscape, very few forests with old-growth characteristics and little human impact exist. One of the rare exceptions is pine forests on rocky soils, a forest type which has probably escaped extensive human use because of its low productivity. LÄS MER

  3. 2. Occurrence patterns of dead wood and wood-dependent lichens in managed boreal forest landscapes

    Författare :Måns Svensson; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Dead wood is a key resource for biodiversity, on which thousands of forest organisms are dependent. Because of current forest management, there has been a large-scale change in dead wood amounts and qualities, and consequently, many wood-dependent species are threatened. LÄS MER

  4. 3. De hädangångnas heraldik : En studie av broderade begravningsfanor ca 1670-1720

  7. 5. Colonization Patterns of Wood-inhabiting Fungi in Boreal Forest

    Författare :Jörgen Olsson; Lars Ericson; Jørund Rolstad; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Wood-inhabiting fungi; colonization; dispersal; restoration fire; saproxylic beetles; conservation; forest management; boreal forest; Terrestrial ecology; Terrestisk ekologi;

    Sammanfattning : Forest management practices have changed the over-all structure of the Fennoscandian forest landscape resulting in a lack of suitable substrates for many wood-inhabiting species. The objectives of this thesis was to describe the colonization patterns of wood-inhabiting fungi, including the potential role of beetles as dispersal vectors, on different types of dead wood substrate and assess the importance of active measures in the forest landscape in order to restore biodiversity i.
