  1. 1. Surface and Subsurface Flow Connection and Dominating Runoff Mechanism in Hillslope of Tarfala, Northern Sweden.

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

    Författare :Namika Maharjan; [2023]
    Nyckelord :Advanced Terrestrial Simulator ATS ; hillslope connectivity; tracer test; hydrological modeling; parameter analysis; sub artic regions; hillslope hydrology;

    Sammanfattning : The Sub artic regions are becoming increasingly important due to the effects of climate change. In northern Sweden, thawing of permafrost has led to significant increases in annual minimum flows in several catchments. LÄS MER

  3. 2. Wetland restoration on Öland : a short-term evaluation of vascular plant community composition after topsoil removal and reinstated grazing

    Master-uppsats, SLU/Dept. of Ecology

    Författare :Marta Holmlund; [2023]
    Nyckelord :wetland restoration; vegetation; biodiversity; topsoil removal; Ellenberg indicator values;

    Sammanfattning : Wetlands are recognized as important types of ecosystems, inhabiting rich biodiversity and performing multiple ecosystem services. However, many have been lost because of anthropogenic activities and a majority of the remaining wetland habitats are in bad conditions, displaying both loss of functionality and biodiversity.

  4. 3. LFA support in a changing climate : the interaction between the LFA support and drought periods on the use of agricultural land in Sweden

    Kandidat-uppsats, SLU/Dept. of Economics

    Författare :Ella Jennersjö; [2023]
    Nyckelord :CAP; LFA; climate change; drought; agricultural land use;

    Sammanfattning : With climate change follows an expectation of more extreme weather events, such as droughts, floods and change in seasonal shifts. How climate variability might impact Swedish agriculture and interact with existing policy aiming at keeping agricultural land in production is not well understood. LÄS MER

  5. 4. Minskning av palsmyrar som resultat av klimatförändringar i norra Sverige mellan 1960–2020

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

    Författare :My Apelkvist; [2023]
    Nyckelord :palsmyrar; palsar; norra Sverige; carbon feedback; klimatförändringar;

    Sammanfattning : The climate is changing at a rapid rate. This causes both an increase in temperature and precipitation in the northern high latitudes. Subarctic peatlands contain 30% of the carbon storage in the northern permafrost zone. LÄS MER

  7. 5. Optimal foraging in an Arctic herbivore : How does the foraging behaviour of Svalbard reindeer (Rangifer tarandus platyrhynchus) respond to seasonal changes from summer through autumn of the Arctic tundra?

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

    Författare :Emma Limosa Djurberg; [2023]
    Nyckelord :foraging behaviour; phenology; ungulate; Arctic; Rangifer tarandus platyrhynchus;

    Sammanfattning : Foraging decisions of large herbivores can be affected by many factors and have great effect on both above- and below-ground ecosystems. Here, I determine to which degree temporal (seasonality), or spatial (habitat) factors influence the foraging behaviour of Svalbard reindeer (Rangifer tarandus platyrhynchus) and asses if small-scale foraging behaviour correlates with an animals’ patch residence time.
