• Positioning of aquatic animals based on time-of-arrival and random walk models using YAPS (Yet Another Positioning Solver) 

      Baktoft, Henrik; Gjelland, Karl Øystein; Økland, Finn; Thygesen, Uffe Høgsbro (Journal article; Peer reviewed, 2017)
      Aquatic positional telemetry offers vast opportunities to study in vivo behaviour of wild animals, but there is room for improvement in the data quality provided by current procedures for estimating positions. Here we ...
    • Potential natural immunization against atherosclerosis in hibernating bears 

      Samal, Shailesh Kumar; Fröbert, Ole; Kindberg, Jonas; Stenvinkel, Peter; Frostegård, Johan (Peer reviewed; Journal article, 2021)
      Brown bears (Ursus arctos) hibernate for 5–6 months during winter, but despite kidney insufciency, dyslipidemia and inactivity they do not seem to develop atherosclerosis or cardiovascular disease (CVD). IgM antibodies ...
    • Redefining the oceanic distribution of Atlantic salmon 

      Rikardsen, Audun H.; Righton, David; Strøm, John Fredrik; Thorstad, Eva Bonsak; Gargan, Patrick G.; Sheehan, Timothy F.; Økland, Finn; Chittenden, Cedar; Hedger, Richard David; Næsje, Tor; Renkawitz, Mark; Sturlaugsson, Johannes; Caballero, Pablo; Baktoft, Henrik; Davidsen, Jan Grimsrud; Halttunen, Elina; Wright, Serena; Finstad, Bengt; Aarestrup, Kim (Peer reviewed; Journal article, 2021)
      Determining the mechanisms driving range-wide reductions in Atlantic salmon marine survival is hindered by an insufcient understanding of their oceanic ecology and distribution. We attached 204 pop-up satellite archival ...
    • Stable isotopes reveal diet shift from pre-extinction to reintroduced Przewalski's horses 

      Kaczensky, Petra; Šturm, Martina Burnik; Sablin, Mikhail V.; Voigt, Christian C.; Smith, Steve; Ganbaatar, Oyunsaikhan; Balint, Boglarka; Walzer, Chris; Spasskaya, Natalia N. (Journal article; Peer reviewed, 2017)
      The Przewalski’s horse (Equus ferus przewalskii), the only remaining wild horse within the equid family, is one of only a handful of species worldwide that went extinct in the wild, was saved by captive breeding, and has ...
    • Temporal patterns in the soundscape of a Norwegian gateway to the Arctic 

      Aniceto, Ana Sofia; Ferguson, Elizabeth L.; Pedersen, Geir; Tarroux, Arnaud; Primicerio, Raul (Peer reviewed; Journal article, 2022)
      As an Arctic gateway, the Norwegian Sea sustains a rich diversity of seasonal and resident species of soniferous animals, vulnerable to the effects of climate change and anthropogenic activities. We show the occurrence of ...
    • Territory location and quality, together with climate, affect the timing of breeding in the whitethroated dipper 

      Nilsson, Anna; Slagsvold, Tore; Røstad, Ole Wiggo; Knudsen, E.; Jerstad, Kurt; Cadahia, Luis; Reitan, Trond; Helberg, Morten; Walseng, Bjørn; Stenseth, Nils Christian (Journal article; Peer reviewed, 2019)
      Recent climate change has led to advanced spring phenology in many temperate regions. The phenological response to variation in the local environment, such as the habitat characteristics of the territories birds occupy, ...
    • The Phe362Tyr mutation conveying resistance to organophosphates occurs in high frequencies in salmon lice collected from wild salmon and trout 

      Fjørtoft, Helene Børretzen; Besnier, Francois; Stene, Anne; Nilsen, Frank; Bjørn, Pål Arne; Tveten, Ann-Kristin; Finstad, Bengt; Aspehaug, Vidar; Glover, Kevin (Journal article; Peer reviewed, 2017)
      The parasitic salmon louse, and its resistance to chemical delousing agents, represents one of the largest challenges to the salmon aquaculture industry. We genotyped lice sampled from wild salmon and sea trout throughout ...
    • Tracking neighbours promotes the coexistence of large carnivores 

      López-Bao, José Vicente; Mattisson, Jenny; Persson, Jens; Aronsson, Malin; Andrén, Henrik (Peer reviewed; Journal article, 2016)
      The study of competition and coexistence among similar interacting species has long been considered a cornerstone in evolutionary and community ecology. However, understanding coexistence remains a challenge. Using two ...
    • Wolf habitat selection when sympatric or allopatric with brown bears in Scandinavia 

      Ordiz Fernandez, Andres Avelino; Uzal, Antonio; Milleret, Cyril Pierre; Sanz-Perez, Ana; Zimmermann, Barbara; Wikenros, Camilla; Wabakken, Petter; Kindberg, Jonas; Swenson, Jon; Sand, Håkan (Peer reviewed; Journal article, 2020)
      Habitat selection of animals depends on factors such as food availability, landscape features, and intraand interspecific interactions. Individuals can show several behavioral responses to reduce competition for habitat, ...
