  1. 1. A bear-y strong comeback: Investigating temporal genomic consequences of a recent demographic bottleneck in the Scandinavian brown bear

    Master-uppsats, Uppsala universitet/Institutionen för biologisk grundutbildning

    Författare :Amanda Lindahl; [2023]
    Nyckelord :Evolutionary biology; ancient DNA; bottleneck; whole-genome sequencing;

    Sammanfattning : The Scandinavian brown bear went through a severe bottleneck due to human actions in the early 1900’s that reduced the population to low numbers. After protective measures were taken, the population recovered and today it consists of around 3000 individuals. LÄS MER

  3. 2. Fjällräven i ett föränderligt klimat

    Kandidat-uppsats, SLU/Dept. of Animal Environment and Health

    Författare :Emma Marander; [2022]
    Nyckelord :fjällräv; vulpes lagopus; klimatförändringar;

    Sammanfattning : Climate change is an ongoing threat to the world´s biodiversity, and has an alarming effect on the Arctic. One species that can only be found in this particular habitat is the arctic fox, whose future is threatened by the aversive effects of global warming. The aim of this study was to investigate how climate change is affecting the arctic fox. LÄS MER

  4. 3. Population genetic analyses inform conservation of the endangered Clouded Apollo (Parnassius mnemosyne) butterfly in Sweden

    Master-uppsats, Uppsala universitet/Institutionen för biologisk grundutbildning

  7. 5. Conservation Genomics of the Long-tailed Duck

    Master-uppsats, Uppsala universitet/Institutionen för biologisk grundutbildning

    Författare :Brynhildur Magnúsdóttir; [2021]
    Nyckelord :Long-tailed duck; migration; conservation; population structure; genome;

    Sammanfattning : With increasingly warming climate, many bird species have been forced to respond to environmental changes, and the long-tailed duck (Clangula hyemalis) is no exception. The populations of the long-tailed duck have been in decline the past few decades and the species is classified as globally vulnerable and near threatened in both Iceland and Sweden. LÄS MER
