  1. 1. Reserve selection in boreal forest

    Author : Johanna Lundström; Sveriges lantbruksuniversitet.; [2013]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Abstract : Most boreal forests in North Europe are intensively managed, and the forest landscape is far from its natural stage leading to hundreds of species being threatened in Sweden alone. Reserves are established to protect biodiversity, but since the resources available for conservation do not cover all species in need of protection, effective prioritization is essential. READ MORE

  3. 3. Colonization Patterns of Wood-inhabiting Fungi in Boreal Forest

    University dissertation from Umeå : Ekologi, miljö och geovetenskap

    Author : Jörgen Olsson; Umeå universitet.; [2008]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Wood-inhabiting fungi; colonization; dispersal; restoration fire; saproxylic beetles; conservation; forest management; boreal forest; NATURAL SCIENCES Biology Terrestrial; freshwater and marine ecology Terrestrial ecology; NATURVETENSKAP Biologi Terrestisk; limnisk och marin ekologi Terrestisk ekologi;

    Abstract : 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.

  4. 4. Insect diversity on clearcuts in boreal forest landscapes

    University dissertation from Umeå : Ekologi, miljö och geovetenskap

    Author : Diana Rubene; Sveriges lantbruksuniversitet.; [2014]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Abstract : 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. READ MORE

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

    University dissertation from Stockholm : Department of Ecology, Environment and Plant Sciences, Stockholm University

    Author : Denis Warshan; Stockholms universitet.; [2017]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Cyanobacteria; Feathermosses; Symbiosis; Boreal forest; Gene flow; Proteogenomic; Transcriptomic; Community structure and composition; Dinitrogen fixation; växtfysiologi; Plant Physiology;

    Abstract : 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. READ MORE
