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

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

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

    Abstract : 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. READ MORE

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

    University essay from Umeå universitet/Institutionen för ekologi, miljö och geovetenskap

    Author : Sara Andersson; [2023]
    Keywords : stable isotopes; snow; precipitation; hydrology; orography; earth science;

    Abstract : 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.

    University essay from Göteborgs universitet / Instiutionen för biologi och miljövetenskap

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

    Abstract : 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. READ MORE

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

    University essay from Uppsala universitet/Luft-, vatten- och landskapslära

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

    Abstract : 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. READ MORE

  6. 5. Cryptic refugia vs. Tabula Rasa: Boreal trees in glacial Fennoscandia : Plant growth during the Weichselian glaciation and the early Holocene in northern Europe

    University essay from Umeå universitet/Institutionen för ekologi, miljö och geovetenskap

    Author : Anne van Woerkom; [2016]
    Keywords : boreal trees; Fennoscandia; cryptic refugia; Weichselian; glacial survival;

    Abstract : Recent studies applying innovative technologies, such as genetic analysis and carbon dating, contradict the palynological based assumption that Scots pine (Pinus sylvestris) and Norway spruce (Picea abies) vanished from Fennoscandia during the Last Glacial Maximum (c. 20.000 yrs BP) and re-colonized after the cold Younger Dryas (c. 12.
