  1. 1. Geographical expansion rate of a brown bear population in Fennoscandia and the factors explaining the directional variations

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

    Författare :Lisbet Hougaard Baklid; [2022]
    Nyckelord :Geography; GIS; brown bear; expansion rate; Ursus arctos; Fennoscandia; Sweden; barrier; Earth and Environmental Sciences;

    Sammanfattning : The brown bears, Ursus arctos L., in the Scandinavian peninsula were distributed in almost all counties before aimed reduction during the 1700-1900s (Swenson et al. 1995). From 1981-2013 the population increased more than five times (Chapron et al. LÄS MER

  3. 2. Comparing crossbred and purebred dairy cows for economically important traits

    Master-uppsats, SLU/Dept. of Animal Breeding and Genetics

    Författare :Sofie Liedgren; [2022]
    Nyckelord :Crossbreed; Holstein; Montbéliarde; Jersey; Fertility; Production;

    Sammanfattning : The use of dairy x dairy crossbreeding as a breeding strategy has increased in Sweden, which has led to an increase of Brown Swiss, Jersey and Montbéliarde crosses. Multiple studies have been done on Montbéliarde and Jersey crossbreds in the USA but to our knowledge, no such study has been done on Swedish data. LÄS MER

  4. 3. Surface crevasses on Svalbard: Spatial Distribution Analysis with Focus on the Lomonosovfonna Ice Cap

    Master-uppsats, Uppsala universitet/Institutionen för geovetenskaper

    Författare :Monika Hawrylak; [2021]
    Nyckelord :crevasses; spatial distribution; model; glacier velocity; Lomonosovfonna; Svalbard;

    Sammanfattning : Understanding the formation mechanics of glacial crevasses is crucial in a variety of glacial applications. Besides being a serious safety hazard during field campaigns, crevasses influence calving rates, mass balance, and the hydrological network of glaciers. LÄS MER

  5. 4. Modelling the effects of climate change on ice dynamics at Kangerlussuaq Glacier, Greenland

    Master-uppsats, Stockholms universitet/Institutionen för naturgeografi

    Författare :Jamie Barnett; [2021]
    Nyckelord :Glacier; Greenland; Ice Sheet; Outlet; Discharge; Sea level; Kangerlussuaq; calving; ice mélange; melt; retreat;

    Sammanfattning : A consequence of climate change is rising global sea levels, predicted to bring increased socio-economic and environmental impacts to coastal communities. The Greenland Ice Sheet has become a prominent contributor to rising sea levels, a consequence of the Arctic warming at twice the rate of the global average. LÄS MER

  7. 5. Impact of different atmospheric forcings on surface mass balance estimates in Greenland

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

    Författare :Stina Olandersson; [2018]
    Nyckelord :Physical Geography and Ecosystem analysis; surface mass balance; Greenland; climate models; numerical weather prediction models; surface energy balance; Arctic; climate change; Earth and Environmental Sciences;

    Sammanfattning : The Greenland Ice sheet (GIS) is the second largest ice sheet on Earth and thus stores a large amount of Earths freshwater. Because of climate change and the Arctic amplification, GIS is experiencing changes and increased melt rates. The total mass budget determines the amount of sea level rise caused by input from freshwater from the GIS. LÄS MER
