    The long history of human land use have had a strong influence on ecosystems and landscapes in the boreal forest region of Northern Europe and created semi-natural habitats of high conservation value. In this study, we ...
  • Rekdal, Silje Larsen (Doctoral thesis / Doktoravhandling, 2020)
    All organisms need to fight pathogens to avoid infectious diseases. In vertebrates, two classes of polymorphic genes from the major histocompatibility complex (MHC) are crucial for triggering immune responses against ...
