  1. 1. Diving Deep: Seabird foraging tactics and local prey field

    Master-uppsats, SLU/Dept. Of Aquatic Resources

    Författare :Elin Andersson Sjöholm; [2024]
    Nyckelord :Common Guillemot; Uria aalge; Optimal Foraging theory; Hydroacoustic data; resource selection;

    Sammanfattning : Foragers in patchy environments need to decide what patches to use and how to allocate their time between them. Optimal foraging theory describes these choices through the relationship between energy expenditure and energy gain. LÄS MER

  3. 2. Headfirst into shallow water - Wetland restoration and its contribution to the Habitats Directive

    Master-uppsats, Uppsala universitet/Växtekologi och evolution; Uppsala universitet/Institutionen för biologisk grundutbildning

    Författare :Elin Brandt Korall; [2024]
    Nyckelord :Wetlands; GIS; Restoration; Rewetting; Ecology; LONA; Habitats Directive; Natura 2000; Nature conservation; Våtmarker; GIS; Geografiska informationssystem; Restaurering; Återvätning; LONA; Art- och Habitatsdirektivet; Natura 2000; Naturvård;

    Sammanfattning : Located in the borderland between aquatic and terrestrial environments, the wetlands cover a wide spectrum of habitats and enable living standards for a great variety of organisms. Although important habitats, a great extent of the original wetlands have disappeared in Europe and Sweden due to anthropogenic disturbances. LÄS MER

  4. 3. THE FIRST ACTIVE ACID SULFATE SOIL FOUND OUTSIDE THE BALTIC BASIN, IN VISKA VALLEY WEST COAST OF SWEDEN

    Master-uppsats, Göteborgs universitet/Institutionen för geovetenskaper

    Författare :Johanna Bergström; [2023-09-15]
    Nyckelord :Acid sulfate soil; AS soil; ERT measurements; resistivity; Baltic basin; Swedish west coast; acidification; Tapes transgression;

    Sammanfattning : Acid sulfate (AS) soils are naturally formed but are responsible for environmental problem due to its low pH. Drainage of active AS soils can lead to mobilization of harmful metals and a severe pH drop in nearby aquatic environments, which in turn may harm the ecological conditions. LÄS MER

  5. 4. Sensitivity of Norway Spruce (Picea abies) to inundation.

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

    Författare :Whitney Cleopatra Vlahakis; [2023]
    Nyckelord :Inundation; riparian zone; spruce seedlings; restoration; mortality;

    Sammanfattning : Alteration of river flow regimes due to dams result in modifications of riparian ecosystem, with impacts on vegetation, landforms, and habitats. A key characteristic that differentiates riparian zones from adjacent aquatic and terrestrial environments is the event of periodic flooding and water logging. LÄS MER

  7. 5. Microplastics in Scanian wetlands : Sege river & Kävlinge river

    Kandidat-uppsats, Malmö universitet/Institutionen för Urbana Studier (US)

    Författare :Ludvig Stoltz; Pernilla Leijon; [2023]
    Nyckelord :plastic pollution; wetlands; microplastics; Scania; density separation; plastföroreningar; våtmarker; mikroplaster; Skåne; flotteringsmetod;

    Sammanfattning : It is estimated that 75 million tons of plastics waste is currently in the ocean and expects to increase in line with plastic consumption. Plastic items in natural or aquatic environments are fragmented into smaller pieces called microplastics. Microplastics can enter rivers and lakes through sewage water to end up in wetlands where they sediment. LÄS MER
