  1. 1. Changes in July albedo and its relationship with EVI over the last two decades in the Swedish alpine region

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

    Författare :Vera Grönvik Hende; [2023]
    Nyckelord :Shortwave albedo; Enhanced Vegetation Index EVI ; Alpine vegetation; Scandes; Surface albedo feedback; MODIS; Earth and Environmental Sciences;

    Sammanfattning : Vegetation in the subarctic is expected to respond to climate warming as its growth becomes less temperature limited. This has previously been recorded in the form of treeline advances and increasing shrub cover. Changes in vegetation cover may accelerate warming due to a decrease in summer albedo, in what is termed surface albedo feedback. LÄS MER

  3. 2. Investigating surface spring snow : Changes in the isotopic composition and conductivity along an orographic precipitation gradient in northern Fennoscandia

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

    Författare :Sara Andersson; [2023]
    Nyckelord :stable isotopes; snow; precipitation; hydrology; orography; earth science;

    Sammanfattning : Stable isotopes of oxygen (O18) and hydrogen (H2) are used as proxies of past climates when ice preserved in the polar icecaps. The main assumption when doing paleoclimatic reconstructions using these isotopes is that the isotopic composition of the snow that turned into ice reflect the present temperature of the planet during deposition.

  4. 3. MOUNTAIN ROADS AND THE HOMOGENIZATION OF PLANTS. A study on plant communities and their traits along the elevational gradient.

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

    Författare :Violetta Chernoray; [2022-09-28]
    Nyckelord :anthropogenic disturbance; spatial ecology; Northern Scandes; functional traits; roadsides; beta-diversity.;

    Sammanfattning : Overexploitation, land use, and other anthropogenic disturbances have increased in recent years, and are expected to increase even further. A very common anthropogenic disturbance, that can be seen even as far as in mountain regions, is roads. LÄS MER

  5. 4. Precipitation variability modulates the terrestrial carbon cycle in Scandinavia

    Master-uppsats, Uppsala universitet/Luft-, vatten- och landskapslära

    Författare :Ella Ek; [2021]
    Nyckelord :Terrestrial carbon cycle; NDVI; Precipitation variability; EOF analysis; Scandinavia; Terrestra kolcykeln; NDVI; Nederbördsvariation; EOF analys; Skandinavien;

    Sammanfattning : Climate variability and the carbon cycle (C-cycle) are tied together in complex feedback loops and due to these complexities there are still knowledge-gaps of this coupling. However, to make accurate predictions of future climate, profound understanding of the C-cycle and climate variability is essential. LÄS MER

  7. 5. Den alpina trädgränsen i ett föränderligt klimat - Studie över trädgränsen i de svenska fjällen

    Kandidat-uppsats, Lunds universitet/Miljövetenskaplig utbildning

    Författare :Julia Johansson; [2019]
    Nyckelord :Trädgräns; klimatförändringar; kalfjäll; Sverige; Earth and Environmental Sciences;

    Sammanfattning : As temperatures on Earth are rising, the Polar regions experience most rapid climatic changes. In the Swedish Scandes, the alpine tree line is considered as one of the most sensitive indicators of climate change. Therefore, the aim of this study is to study the most important abiotic factors driving position change of the alpine tree line. LÄS MER
