  1. 1. Loess as an Environmental Proxy for Reconstruction of Palaeoclimate in the High Arctic

    Kandidat-uppsats, Uppsala universitet/Institutionen för geovetenskaper

    Författare :Sara Rognås; [2023]
    Nyckelord :aeolian transport; loess; grain size analysis; loss on ignition; palaeoclimate; Svalbard; Holocene; vindtransporterat material; lössjord; kornstorlek; loss on ignition; paleoklimat; Svalbard; Holocen;

    Sammanfattning : We are currently speeding towards significant changes in the climate of the earth which, if ignored, will lead to severely altered climatic conditions with serious consequences for several species and ecosystems. The polar regions especially are very sensitive to climate changes, and the changes these regions undergo affect the climate on a global scale. LÄS MER

  3. 2. Reconstructing Mid-Late Holocene Arctic Climate Using Loess Deposits From Kangerlussuaq, Greenland

    Kandidat-uppsats, Uppsala universitet/Institutionen för geovetenskaper

    Författare :William Mörtsjö Zung; [2023]
    Nyckelord :;

    Sammanfattning : The current geological epoch, the Holocene, began 11,700 years ago. During this time, a thermal maximum in temperature was reached somewhere during the early-middle stage at 8-5 kyrs ago which was followed by a period of neoglacial cooling, culminating in the little ice age (LIA).

  4. 3. Feasibility of reintroduction of European Bison (Bison bonasus) to Sweden with focus on traffic accidents

    Master-uppsats, SLU/Southern Swedish Forest Research Centre

    Författare :Michael Topszewski; [2023]
    Nyckelord :wildlife-vehicle collision; risk prediction; reintroduction feasibility; european bison; Bison bonasus; moose; Alces alces; Human-wildlife conflict;

    Sammanfattning : The historical occurrence of European bison (Bison bonasus) in Sweden during the early Holocene emphasizes the ecological significance for a potential reintroduction. The European bison, the largest herbivore on the European continent, is a keystone species with a significant influence on ecosystem dynamics. LÄS MER

  5. 4. Holocene vegetation change and its correlates in fennoscandia

    Master-uppsats, Göteborgs universitet / Institutionen för biologi och miljövetenskap

    Författare :Raphaela Infanger; [2022-10-21]
    Nyckelord :Fennoscandia; Holocene; human impact; climate impact; vegetation change; fossil pollen;

    Sammanfattning : Climatic and anthropogenic legacy has differently impacted vegetation and its community composition. To determine the extent and origin of changes across Fennoscandia, representative regions were defined that entailed sufficient spatial and temporal data. LÄS MER

  7. 5. Marine Geology and Holocene Paleoceanographyof the Southern Quark, Baltic Sea

    Master-uppsats, Stockholms universitet/Institutionen för geologiska vetenskaper

    Författare :Anton Wagner; [2022]
    Nyckelord :Bottom currents; Sortable silt; Radiocarbon dating; Baltic Sea stages; Estuarine circulation; Marine sediment cores; Marine geophysical mapping;

    Sammanfattning : The Understen-Märket trench is located in the Southern Quark and is the only deep-water connection between the Baltic Propper and the Gulf of Bothnia. Bathymetric mapping reveals a number of eroded channels and drift deposits exists on the seafloor, indicating that the area is heavily affected by current activity. LÄS MER
