  1. 1. Effects of natural warming and snow on grass phenology and fitness

    Master-uppsats, Uppsala universitet/Institutionen för biologisk grundutbildning

    Författare :Sanne Welin; [2022]
    Nyckelord :Ecology; Climate change; Iceland; Grass; Festuca rubra;

    Sammanfattning : Organisms respond to changes in their environment using different strategies. Understanding how species deal with changes expected due to ongoing climate change is important for making accurate predictions about their effect on ecosystems. LÄS MER

  2. 2. Effects of climate change on freezing damage in three subarctic bryophyte species

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

    Författare :Marlene Kassel; [2017]
    Nyckelord :freezing damage; bryophytes; subarctic; climate change;

    Sammanfattning : Climate change is expected to have a strong impact on subarctic ecosystems. Increased temperatures as well as altered precipitation and snow cover patterns are predicted to change species distribution and affect biogeochemical processes in the subarctic tundra. LÄS MER

  3. 3. The impact of permafrost degradation on methane fluxes : a field study in Abisko

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

    Författare :Andreas Dahlbom; [2016]
    Nyckelord :Physical Geography and Ecosystem analysis; methane; chamber technique; permafrost; Abisko; Earth and Environmental Sciences;

    Sammanfattning : All over the arctic and sub-arctic region global warming is affecting permafrost. When permafrost thaws, organic material becomes available for decomposition, hence an increase of greenhouse gas emissions to the atmosphere. In the northernmost of Sweden, on a mire close to Abisko, a snow manipulation project is ongoing. LÄS MER

  4. 4. Climate change effects on freezing damage in three subarctic bryophytes : A snow manipulation field experiment in a tundra ecosystem in Abisko, Sweden

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

    Författare :Kristel van Zuijlen; [2015]
    Nyckelord :freezing damage; bryophytes; tundra; climate change; snow manipulation experiment;

    Sammanfattning : Climate change is expected to have a large impact on northern ecosystems. Increased temperatures and altered precipitation and snow cover patterns will have a great impact on subarctic tundra. Bryophytes form an important component of tundra ecosystems because of their high abundance and their importance in many ecological processes. LÄS MER

  5. 5. The potential impact of changing vegetation on thawing permafrost : effects of manipulated vegetation on summer ground temperatures and soil moisture in Abisko, Sweden

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

    Författare :Eric Torkelsson; John Bengtsson; [2012]
    Nyckelord :vegetation manipulation experiment; permafrost; climate change; physical geography; geography; Abisko; sub-arctic; naturgeografi; geografi; klimatförändring; manipulation av vegetation; subarktis; Earth and Environmental Sciences;

    Sammanfattning : The Arctic region has experienced significant warming in the past decades and according to predictions further increases in air temperatures and precipitation will occur during the 21st century. Recent changes in climate have had widespread implications for the permafrost around the Arctic. LÄS MER
