(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2018)
    The evolutionary history of the wolf-like canids of the genus Canis has been heavily debated, especially regarding the number of distinct species and their relationships at the population and species level [1, 2, 3, 4, 5, ...

    The terrestrial environment of the High Arctic consists of a mosaic of habitat types. In addition to the natural habitat diversity, various human-influenced types may occur. For the resident invertebrate fauna, these ...
  • Johnsen, Arild; Pauliny, Angela; Lifjeld, Jan Terje; Blomqvist, Donald (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2017)
    Telomere length is related to aging in many eukaryotes and the rate of telomere attrition has been suggested to reflect individual genetic quality. Telomere length could thus have implications for mate choice. We investigated ...
