• Later at higher latitudes: large-scale variability in seabird breeding timing and synchronicity 

      Burr, Zofia M.; Varpe, Øystein; Anker-Nilssen, Tycho; Erikstad, Kjell E; Descamps, Sébastien; Barrett, Robert T; Bech, Claus; Christensen-Dalsgaard, Signe; Lorentsen, Svein-Håkon; Moe, Børge; Reiertsen, Tone Kristin; Strøm, Hallvard (Journal article; Peer reviewed, 2016-05-28)
      In seasonal environments, organisms are expected to optimally schedule reproduction within an annual range of environmental conditions. Latitudinal gradients generate a range of seasonality to which we can expect adaptations ...
    • Moult location and diet of auks in the North Sea inferred from coupled light-based and isotope-based geolocation 

      Glew, Katie St. John; Wanless, Sarah; Harris, Michael P.; Daunt, Francis; Erikstad, Kjell E; Strøm, Hallvard; Trueman, Clive N. (Journal article; Peer reviewed, 2018)
      Many pelagic seabirds moult their feathers while at sea, which is an energetically costly behaviour. Mortality rates during moult can be high, so spatial and trophic ecology during this critical period is important for ...
    • Multicolony tracking reveals potential threats to little auks wintering in the North Atlantic from marine pollution and shrinking sea ice cover 

      Fort, Jérôme; Moe, Børge; Strøm, Hallvard; Grémillet, David; Welcker, Jorg; Schultner, Jannik; Jerstad, Kurt; Johansen, Kasper L.; Phillips, Richard A.; Mosbech, Anders (Journal article; Peer reviewed, 2013)
      Aim Extensive development of human activities in combination with ocean warming is rapidly modifying marine habitats in the Arctic and North Atlantic regions. To understand the potential impacts on marine biodiversity, ...
    • A risk assessment of the effects of mercury on Baltic Sea, Greater North Sea and North Atlantic wildlife, fish and bivalves 

      Dietz, Rune; Fort, Jérôme; Sonne, Christian; Albert, Céline; Bustnes, Jan Ove; Christensen, Thomas Kjær; Ciesielski, Tomasz Maciej; Danielsen, Jóhannis; Dastnai, Sam; Eens, Marcel; Erikstad, Kjell E; Galatius, Anders; Garbus, Svend-Erik; Gilg, Oliver; Hanssen, Sveinn Are; Helander, Björn; Helberg, Morten; Jaspers, Veerle; Jenssen, Bjørn Munro; Jónsson, Jón Einar; Kauhala, Kaarina; Kolbeinsson, Yann; Kyhn, Line A.; Labansen, Aili Lage; Larsen, Martin M.; Lindstrøm, Ulf; Reiertsen, Tone Kristin; Rigét, Frank F.; Roos, Anna; Strand, Jakob; Strøm, Hallvard; Søndergaard, Jens; Sun, Jiachen; Teilmann, Jonas; Therkildsen, Ole Roland; Thórarinsson, Thorkell Lindberg; Tjørnløv, Rune Skjold; Wilson, Simon; Eulaers, Igor (Peer reviewed; Journal article, 2020)
      A wide range of species, including marine mammals, seabirds, birds of prey, fish and bivalves, were investigated for potential population health risks resulting from contemporary (post 2000) mercury (Hg) exposure, using ...
    • Strong migratory connectivity across meta-populations of sympatric North Atlantic seabirds 

      Merkel, Benjamin; Descamps, Sebastien; Yoccoz, Nigel; Grémillet, David; Fauchald, Per; Danielsen, Jóhannis; Daunt, Francis; Erikstad, Kjell E.; Ezhov, Aleksey V.; Harris, Mike P.; Gavrilo, Maria; Lorentsen, Svein-Håkon; Reiertsen, Tone Kristin; Systad, Geir Helge Rødli; Thórarinsson, Thorkell Lindberg; Wanless, Sarah; Strøm, Hallvard (Peer reviewed; Journal article, 2021)
      Identifying drivers of population trends in migratory species is difficult, as they can face many stressors while moving through different areas and environments during the annual cycle. To understand the potential of ...
    • Sympatric Atlantic puffins and razorbills show contrasting responses to adverse marine conditions during winter foraging within the North Sea 

      St. John Glew, Katie; Wanless, Sarah; Harris, Michael P.; Daunt, Francis; Erikstad, Kjell E; Strøm, Hallvard; Speakman, John R.; Kürten, Benjamin; Trueman, Clive N. (Journal article; Peer reviewed, 2019)
      Background: Natural environments are dynamic systems with conditions varying across years. Higher trophic level consumers may respond to changes in the distribution and quality of available prey by moving to locate new ...
