  1. 1. Hyperspectral and multispectral satellite data analysis of nitrogen in grazed and ungrazed tundra in Långfjället, Sweden

    Master-uppsats, Göteborgs universitet/Institutionen för geovetenskaper

    Författare :Emma Dahlstedt; [2023-08-18]
    Nyckelord :Hyperspectral imaging; Imaging spectroscopy; Nitrogen; Reindeer; Herbivory; Tundra; Grazing;

    Sammanfattning : Reindeer are a keystone species in the circumpolar north, where they hold great cultural and ecological importance. Continued climate change threatens the long-term sustainability of reindeer husbandry. Reindeer can affect the tundra landscape, influencing the soil nutrient cycling, including the soil nitrogen availability. LÄS MER

  3. 2. INFLUENCE OF TEMPERATURE ON BIOMASS AND GROWTH RATE OF BENTHIC DIATOMS

    Master-uppsats, Göteborgs universitet / Institutionen för biologi och miljövetenskap

    Författare :Evelina Hansson; [2023-06-21]
    Nyckelord :benthic; diatoms; cultivation; thermal performance; photosynthetic pigments;

    Sammanfattning : Temperature has a significant impact on structure and abundance of microalgal community as well as on physiology (Sheehan et al., 2020). LÄS MER

  4. 3. Changes in lake-water organic carbon over recent centuries in northern Sweden, Västerbotten : Past and present mechanisms, and the potential implications on mercury

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

    Författare :Magnusson Petter; [2023]
    Nyckelord :Lake-water TOC; Summer forest farming; traditional agriculture; land-use; geochemistry; mercury;

    Sammanfattning : Due to the current increase in lake water total organic carbon (LW-TOC), many studies have investigated the long-term dynamics using lake sediments. However, these have mainly been focused on Sweden’s south and south-central parts. LÄS MER

  5. 4. Greenhouse gas emissions and carbon burial in a small pond

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Institutionen för geovetenskaper

    Författare :Maria Carlson; [2023]
    Nyckelord :Pond; greenhouse gas; carbon dioxide; methane; nitrous oxide; flux; ebullition; carbon burial; Damm; växthusgas; koldioxid; metan; lustgas; flöde; ebullition; kolbindning;

    Sammanfattning : There are a lot of uncertainties when it comes to global greenhouse gas (GHG) emissions which affects society’s ability to effectively respond to climate change. Small ponds have been found to potentially play a large role in global warming. LÄS MER

  7. 5. Mussel farming along the south-Swedish coasts - a possible solution to eutrophication?

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

    Författare :David Trulsson; [2023]
    Nyckelord :Mussel farming; Aquaculture; Spatial suitability analysis; Eutrophication; Baltic Sea; Biology and Life Sciences; Earth and Environmental Sciences;

    Sammanfattning : The concept of mussel farming as a mitigator to nutrient pollution is steadily spreading. The southernmost part of Sweden borders the Baltic Sea where the water quality differs between the costs, however, all are affected by eutrophication. LÄS MER
