    • Consequences of cross-season demographic correlations for population viability 

      Layton-Matthews, Kate; Reiertsen, Tone Kristin; Erikstad, Kjell E.; Anker-Nilssen, Tycho; Daunt, Francis; Wanless, Sarah; Barrett, Robert; Newell, Mark A; Harris, Mike P. (Peer reviewed; Journal article, 2023)
      Demographic correlations are pervasive in wildlife populations and can represent important secondary drivers of population growth. Empirical evidence suggests that correlations are in general positive for long-lived ...

      Albert, Céline; Bråthen, Vegard Sandøy; Descamps, Sebastien; Anker-Nilssen, Tycho; Cherenkov, A.; Christensen-Dalsgaard, Signe; Danielsen, Johannis; Erikstad, Kjell E.; Gavrilo, Maria; Hanssen, Sveinn Are; Helgason, Halfdan Helgi; Jonsson, Jón Einar; Kolbeinsson, Yann; Krasnov, Yuri V.; Langset, Magdalene; Lorentzen, Erlend; Olsen, Bergur; Reiertsen, Tone Kristin; Strøm, Hallvard; Systad, Geir Helge Rødli; Tertitski, G.; Thompson, P.M; Thórarinsson, Torkell Lindberg; Bustamante, P.; Moe, Børge; Fort, Jérôme (Peer reviewed; Journal article, 2021)
      Migratory seabirds are exposed to various pollutants throughout their annual cycle. Among them, mercury (Hg) is of particular concern given its large impact on animal health. Recent studies suggest that winter is a critical ...

    • Multi-colony tracking of two pelagic seabirds with contrasting flight capability illustrates how windscapes shape migratory movements at an ocean-basin scale

      Migration is a common trait among many animals allowing the exploitation of spatiotemporally variable resources. It often implies high energetic costs to cover large distances, for example between breeding and wintering ...

    • North Atlantic winter cyclones starve seabirds 

      Clairbaux, Manon; Mathewson, Paul; Porter, Warren; Fort, Jérôme; Strøm, Hallvard; Moe, Børge; Fauchald, Per; Descamps, Sebastien; Helgason, Halfdan Helgi; Bråthen, Vegard Sandøy; Merkel, Benjamin; Anker-Nilssen, Tycho; Bringsvor, Ingar Støyle; Chastel, Olivier; Christensen-Dalsgaard, Signe; Danielsen, Jóhannis; Daunt, Francis; Dehnhard, Nina; Erikstad, Kjell E.; Ezhov, Alexey V.; Gavrilo, Maria; Krasnov, Yuri V.; Langset, Magdalene; Lorentsen, Svein-Håkon; Newell, Mark; Olsen, Bergur; Reiertsen, Tone Kristin; Systad, Geir Helge Rødli; Thórarinsson, Thorkell L; Baran, Mark; Diamond, Tony; Fayet, Annette L.; Fitzsimmons, Michelle G.; Frederiksen, Morten; Gilchrist, Hugh G.; Guilford, Tim; Huffeldt, Nicholas P.; Jessopp, Mark; Johansen, Kasper L.; Kouwenberg, Amy-Lee; Linnebjerg, Jannie F.; Major, Heather L.; Tranquilla, Laura McFarlane; Mallory, Mark; Merkel, Flemming R.; Montevecchi, William A.; Mosbech, Anders; Petersen, Aevar; Grémillet, David (Peer reviewed; Journal article, 2021)
      Each winter, the North Atlantic Ocean is the stage for numerous cyclones, the most severe ones leading to seabird mass-mortality events called ‘‘winter wrecks.’’ During these, thousands of emaciated seabird carcasses are ...

    • Predicting the foraging patterns of wintering Auks using a sea surface temperature model for the Barents Sea 

      Hodges, Samuel; Erikstad, Kjell E.; Reiertsen, Tone Kristin (Peer reviewed; Journal article, 2022)
      1. The conservation of seabirds is increasingly important for their role as indicator species of ocean ecosystems, which are predicted to experience increasing levels of exploitation this century. Safeguarding these ...

    • Raising offspring increases ageing: Differences in senescence among three populations of a long-lived seabird, the Atlantic puffin 

      Landsem, Terje Lorentzen; Yoccoz, Nigel Gilles; Layton-Matthews, Kate; Hilde, Christoffer Høyvik; Harris, Michael P; Wanless, Sarah; Daunt, Francis; Reiertsen, Tone Kristin; Erikstad, Kjell E.; Anker-Nilssen, Tycho (Peer reviewed; Journal article, 2023)
      1. Actuarial senescence, the decline of survival with age, is well documented in the wild. Rates of senescence vary widely between taxa, to some extent also between sexes, with the fastest life histories showing the highest ...

    • Seasonal variation of mercury contamination in Arctic seabirds: A pan-Arctic assessment
