  1. 1. Identification of restoration hotspots in landscape-scale green infrastructure planning based on model-predicted connectivity forest

    Master-uppsats, Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Författare :Xiaoming Wang; [2023]
    Nyckelord :boreal forest; conservation; restoration; connectivity; green infrastructure; GIS; Sweden; Earth and Environmental Sciences;

    Sammanfattning : Boreal forest landscapes have undergone severe anthropogenic fragmentation and their enormous values concerning, e.g., ecosystem service, biodiversity and culture are hazarded. LÄS MER

  3. 2. Lavar i skogsöar i en fragmenterad skogsmiljö

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

    Författare :Christian Mendez From; [2023]
    Nyckelord :Boreal forest; Fragmentation; Habitat; Lichenes; Island biogeography; Species-area concept.;

    Sammanfattning : Epiphytic lichens are important species in the forest ecosystem. The Swedish forestry model affects them by fragmenting large old continuous forests. These fragments could be used as islands in a test of MacArthur and Wilsons theory of island biogeography. LÄS MER

  4. 3. Habitat types in relation to bird diversity in boreal forestry landscapes in Sweden

    Master-uppsats, Uppsala universitet/Institutionen för biologisk grundutbildning

    Författare :Engla Grönvall; [2023]
    Nyckelord :Biodiversty; Forestry; Bird diversity; Habitat types; Species Richness;

    Sammanfattning : Boreal forests in Europe are intensively managed for timber and pulp production, resulting in decreased biodiversity, and in the long-term leading to a reduced number of functioning ecosystem services. To develop a more sustainable forest management it is important to investigate what features and habitat types are needed to preserve a high diversity of species within the forestry landscapes.

  5. 4. Älgens och skogshönsens nyttjande av ett två år gammalt brandfält

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

    Författare :Alice Kårehagen; Hannah Sophie Jakob; [2022]
    Nyckelord :älg; Alces alces; skogshöns; Tetraoninae; brand; skogsbrand; älgbete; Ljusdal;

    Sammanfattning : Forest fires have had an extensive impact on our landscapes. Natural forest fires are especially important for the regeneration of pine and nutrition cycle in the boreal zone. LÄS MER

  7. 5. Forest Ditches As Habitat For Aquatic Macroinvertebrate In Boreal Landscapes

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

    Författare :Lara Sánchez Calderón; [2022]
    Nyckelord :aquatic macroinvertebrates; drainage ditches; Sweden; mineral soil; peat soil; forestry;

    Sammanfattning : Large areas of northern Sweden have been ditched to promote forest growth by draining wet soils and peatlands. These ditches have greatly added to length of Sweden’s stream and river network, but the ecological properties of these man-made aquatic environments is poorly understood. LÄS MER
