  2. 6. Impacts of clear-cutting on soil fungal communities and their activities in boreal forests - A metatranscriptomic approach

    Author : Fahri Hasby; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Abstract : Large-scale forestry has reduced and fragmented the area of primary forest and greatly impacted communities of organisms, above and below ground. Fungal com-munities, which are pivotal in boreal forest soil functions, are vulnerable to tree har-vesting. READ MORE

  4. 7. The long-term history of temperate broadleaves in southern Sweden

    Author : Tove Hultberg; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : Temperate broadleaves used to be abundant in the primeval forests in southern Sweden, yet today they cover only fractions of the forest land. Considering the present small area of the forest type, the habitat is of considerable interest for biodiversity, and knowledge about the history of temperate broadleaves is crucial for forest conservation and management.

  5. 8. Strengthening conservation through green infrastructure : linking protected areas, habitats and species

    Author : Ewa Orlikowska; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : The green infrastructure (GI) concept was developed to mitigate habitat fragmentation. The European Union (EU) defines GI as “a strategically planned network of natural and semi-natural areas …designed and managed to deliver a wide range of ecosystem services and to improve connectivity of protected areas in order to promote multifunctional landscapes”.

  6. 9. Anthropogenic Open Land in Boreal Landscapes : Investigations into the Creation and Maintenance of Arable Fields on Swedish Farms

    Author : Lovisa Solbär; Institutionen för kulturgeografi och ekonomisk geografi; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Landscape; timespace; time-geography; farming; boreal land use; time-economy; embedded values;

    Abstract : The human-induced open land (cropland, pasture) in the predominantly forested boreal landscapes relies on arable land use; it thus represents an active intervention to hold back forest regrowth. The thesis investigates the practical management decisions by landholders on discrete farms, which in Sweden often comprise both forest and arable lands. READ MORE

  7. 10. Ecology of lichens in boreal coniferous forests with reference to spatial and temporal patterns

    Author : Per-Anders Esseen; Lars Ericson; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Lichens; epiphytes; Alectoria; Bryoria; Cladonia; Usnea; Picea abies; Pinus sylvestris; dispersal; litterfall; succession; diversity; spatial patterns;

    Abstract : The thesis deals with the ecology of lichens in two contrasting types of forest, epiphytic lichens in old Picea abies forest of the fi re-refugia type and epigeic as well as epixylic lichens in a successional sequence of fire- susceptible Pinus sylvestris forests. Results in five separate papers form the basis for a discussion of general patterns of dispersal, succession and life strategies in lichens. READ MORE
