  1. 1. Utvärdering av biotopvårdande åtgärder i Grimåsbäcken. En analys av fysikaliska egenskaper och sammansättning av makroevertebrater.

    Kandidat-uppsats, Göteborgs universitet / Instiutionen för biologi och miljövetenskap

    Författare :Björn Andermo; [2024-01-22]
    Nyckelord :Channelized streams; retention; biotope preservation; macroinvertebrates; bottom substrate; woody debris.;

    Sammanfattning : Many streams have been exposed to extensive anthropogenic impact for the benefit of forestry and agriculture. The effects has mainly been channelization characterized by lowered and straightened channels. This homogeneous morphology leads to decreased ability to retain water as well as lost connection to the floodplain. LÄS MER

  3. 2. Optimization of Solid-State Fermentation process for brown seaweed using LAB and characterization of the products

    Master-uppsats, Lunds universitet/Bioteknik (CI); Lunds universitet/Bioteknik (master)

    Författare :Sweta Singh; [2024]
    Nyckelord :lactic acid bacteria; solid-state fermentation; Alaria esculenta; Saccharina latissima; seaweed fermentation; biotechnology; Technology and Engineering;

    Sammanfattning : Fermentation has played a vital role in human history, offering solutions for food preservation, culinary diversity, and the creation of diverse and flavorful foods and beverages. Its importance continues today, both in traditional practices and in modern industrial applications. LÄS MER

  4. 3. Gatuträd för framtidens klimat och infrastruktur : förslag på lämpliga trädarter till ett stadsträdsarboretum i Ultuna

    Uppsats för yrkesexamina på avancerad nivå, SLU/Dept. of Urban and Rural Development

    Författare :Malkolm Bonander; [2023]
    Nyckelord :Stadsträdsarboretum; gatuträd; kolmakadam; växtbädd; spårväg; infrastruktur; klimatförändringar; diversitet; exotiska arter;

    Sammanfattning : Arbetet syftar till att inhämta och analysera aktuell kunskap och forskning för att ange kriterier för lämpliga trädarter och växtbäddar som kan möta infrastruktursatsningar i ett allt varmare klimat i urban miljö. Exploatering med tungt trafikerade gator skapar tuffa levnadsförhållanden för stadens gatuträd. LÄS MER

  5. 4. Impact of forest management on the diversity of wood decaying fungi : A comparison between two closely related forests in southern Sweden

    Kandidat-uppsats, Linköpings universitet/Biologi

    Författare :Johanna Sollén Mattsson; [2022]
    Nyckelord :Biodiversity; Boreal forests; Forest management; Forestry; Natural forests; Wood decaying fungi;

    Sammanfattning : Modern forestry practices have negative effects on many organisms because they change the forest’s disturbance dynamics, makes the forest’s structure less complex, and fragments old-growth forests. This study examined how commercial forestry practices affect the diversity of wood-decaying fungi, by comparing two closely related forests with different management in Östergötland, Sweden. LÄS MER

  7. 5. How hot are retention patches as structural hotspots? : comparing key elements for biodiversity in retention patches and reference forest stands

    Master-uppsats, SLU/Dept. of Wildlife, Fish and Environmental Studies

    Författare :Maja Östlund; [2022]
    Nyckelord :retention forestry; retention patches; deadwood; live conservation trees; retention forestry; biodiversity preservation; substrate diversity;

    Sammanfattning : Sweden’s historical and current forestry regime has created structurally simplified forest stands with little resemblance of boreal old-growth forests, leading to a decline in many forest dwelling species. Retention forestry was introduced to counteract the negative development by retaining biologically important forest elements. LÄS MER
