  1. 1. Do OTC warming effects on ecosystem processes depend on moss species identity, precipitation, and moss removal?

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

    Författare :Alexina Brännlund; [2023]
    Nyckelord :Experimental warming; Subarctic tundra mosses; Productivity; Ecosystem respiration; Decomposition;

    Sammanfattning : Long-term warming experiments in arctic tundra have resulted in reduced moss cover and increased vascular plant cover. As mosses have a major impact on microclimatic conditions, changes in community composition can potentially alter direct and indirect drivers of productivity and decomposition, which are low in arctic ecosystems.

  3. 2. Applying LPJ-GUESS on the Arctic: A model evaluation and benchmarking study

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

    Författare :Margot Jeanne Knapen; [2023]
    Nyckelord :Physical Geography and Ecosystem Analysis; LPJ-GUESS; Arctic; FLUXNET; Gross Primary Productivity; Ecosystem Respiration; Permafrost; Active Layer Thickness; Snow Depth; Earth and Environmental Sciences;

    Sammanfattning : Warming in the Arctic occurs at a much higher rate than the global average, which has a considerable impact on the Arctic terrestrial carbon cycle. Permafrost thawing can release substantial amounts of carbon, whilst tundra shrubification and tree-line advance, on the other hand, may compensate for this. LÄS MER

  4. 3. Potential for Enhanced Biological Phosphorus Removal in an activated sludge system for greywater

    Master-uppsats, Lunds universitet/Kemiteknik (CI)

    Författare :Mehrzad Ghassemi; [2022]
    Nyckelord :Greywater; EBPR; Phosphorus; Biological treatment; Water and environmental engineering; Technology and Engineering;

    Sammanfattning : As the world's population grows, concerns about water scarcity and rising pollution such as phosphorus and nitrogen have increased significantly. Greywater has been considered by researchers as an ideal alternative to fresh water for decades, and several projects have been implemented to treat and recycle it for various reuse purposes.

  5. 4. Kognitiva nedsättningar som faller mellan stolarna: vilken betydelse har premorbid nivå för bedömning av kognitiv funktion vid utmattningssyndrom?

    Master-uppsats, Umeå universitet/Institutionen för psykologi

    Författare :Alva Holmgren; Rebecca Sommarlund; [2022]
    Nyckelord :stress; exhaustion disorder; cognitive impairment; work ability; idiographic approach; normative approach; cut-offs; stress; utmattningssyndrom; kognitiv nedsättning; arbetsförmåga; ideografisk ansats; normativ ansats; gränsvärden;

    Sammanfattning : Stressrelaterad ohälsa är en av de vanligaste sjukskrivningsorsakerna i västvärlden. I Sverige diagnostiseras vanligen långvarig stressrelaterad ohälsa som utmattningssyndrom. Vid utmattningssyndrom är kognitiva besvär ett framträdande symptom som kan vara långvarigt. LÄS MER

  7. 5. Influence of permafrost disintegration on wetland carbon fluxes in Abisko, Sweden

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

    Författare :Aida Esmailzadeh Davani; [2021]
    Nyckelord :Physical Geography; Ecosystem Analysis; Permafrost; CH4 flux; CO2 flux; Abisko; Wetlands; Earth and Environmental Sciences;

    Sammanfattning : The northern permafrost regions are experiencing a rapid warming as surface temperatures are rising, causing a disintegration of permafrost and a deepening of the active layer (AL). This releases previously frozen carbon, making it available for decomposition by microbes. LÄS MER
