    • Diel vertical migration of Arctic zooplankton during the polar night 

      Berge, Jørgen; Cottier, Finlo; Last, Kim S.; Varpe, Øystein; Leu, Eva; Søreide, Janne; Eiane, Ketil; Falk-Petersen, S.; Willis, Kate; Nygård, Henrik; Vogedes, Daniel; Griffiths, Collin; Johnsen, Geir; Lorentzen, Dag Arne; Brierley, A.S. (Journal article; Peer reviewed, 2009)
      High-latitude environments show extreme seasonal variation in physical and biological variables. The classic paradigm of Arctic marine ecosystems holds that most biological processes slow down or cease during the polar ...

    • Earlier colony arrival but no trend in hatching timing in two congeneric seabirds (Uria spp.) across the North Atlantic 

      Merkel, Benjamin; Descamps, Sebastien; Yoccoz, Nigel Gilles; Danielsen, Jóhannis; Daunt, Francis; Erikstad, Kjell E; Ezhov, Aleksey V.; Grémillet, David; Gavrilo, Maria; Lorentsen, Svein Håkon; Reiertsen, Tone Kristin; Steen, Harald; Systad, Geir Helge Rødli; Þórarinsson, Þorkell Lindberg; Wanless, Sarah; Strøm, Hallvard (Peer reviewed; Journal article, 2019)
      A global analysis recently showed that seabird breeding phenology (as the timing of egg-laying and hatching) does not, on average, respond to temperature changes or advance with time (Keogan et al. 2018 Nat. Clim. Change ...

    • A marine zooplankton community vertically structured by light across diel to interannual timescales 

      Hobbs, Laura; Banas, Neil S.; Cohen, Jonathan H.; Cottier, Finlo Robert; Berge, Jørgen; Varpe, Øystein (Journal article; Peer reviewed, 2021)
      The predation risk of many aquatic taxa is dominated by visually searching predators, commonly a function of ambient light. Several studies propose that changes in visual predation will become a major climate-change impact ...

    • Migration and stress during reproduction govern telomere dynamics in a seabird 

      Schultner, Jannik; Moe, Børge; Chastel, Olivier; Bech, Claus; Kitaysky, Alexander S. (Journal article; Peer reviewed, 2014)
      Changes in telomere length are believed to reflect changes in physiological state and life expectancy in animals. However, much remains unknown about the determinants of telomere dynamics in wild populations, and specifically ...

    • Responses of neurogenesis and neuroplasticity related genes to elevated CO2 levels in the brain of three teleost species 

      Lai, Floriana; Fagernes, Cathrine Elisabeth; Bernier, Nicholas J; Miller, Gabrielle; Munday, Philip L; Jutfelt, Fredrik; Nilsson, Göran Erik (Journal article; Peer reviewed, 2017)
      The continuous increase of anthropogenic CO2 in the atmosphere resulting in ocean acidification has been reported to affect brain function in some fishes. During adulthood, cell proliferation is fundamental for fish brain ...
