    • Corticosterone mediates carry-over effects between breeding and migration in the kittiwake Rissa tridactyla 

      Schultner, Jannik; Moe, Børge; Chastel, Olivier; Tartu, Sabrina; Bech, Claus; Kitaysky, Alexander S. (Journal article; Peer reviewed, 2014)
      Carry-over effects, i.e. when processes in one season influence processes in the next, are believed to have important effects on behavior and fitness in animals. Despite an increasing interest in the identification of ...

    • Inter-population synchrony in adult survival and effects of climate and extreme weather in non-breeding areas of Atlantic puffins 

      Reiertsen, Tone Kristin; Layton-Matthews, Kate; Erikstad, K.E.; Hodges, Kevin I.; Ballesteros, Manuel; Anker-Nilssen, Tycho; Barrett, R.T.; Benjaminsen, Sigurd; Bogdanova, M.; Christensen-Dalsgaard, Signe; Daunt, Francis; Dehnhard, Nina; Harris, Michael P.; Langset, Magdalene; Lorentsen, Svein-Håkon; Newell, Mark; Bråthen, Vegard Sandøy; Støyle-Bringsvor, I.; Systad, Geir Helge Rødli; Wanless, Sarah (Peer reviewed; Journal article, 2021)
      Seabirds are undergoing drastic declines globally and spend the non-breeding season at sea, making it challenging to study the drivers of their survival. Harsh weather and changes in climate conditions can have large impacts ...

    • 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 ...

    • Ocean climate and egg investment in the black-legged kittiwake Rissa tridactyla. 

      Barrett, Robert T; Erikstad, Kjell E; Reiertsen, Tone (Journal article; Peer reviewed, 2017)
      Birds allocate substantial resources to their eggs during the laying period, resources also needed for other concurrent costly processes such as mate acquisition, nest building and site defence. Egg and clutch sizes may ...

    • Seabirds as guides for fisheries management: European shag Phalacrocorax aristotelis diet as indicator of saithe Pollachius virens recruitment 

      Lorentsen, Svein Håkon; Anker-Nilssen, Tycho; Erikstad, Kjell E (Journal article; Peer reviewed, 2018)
      In fisheries management, assessing year-class strength and recruitment to commercial stocks is essential, but can be difficult to do for fish species where the young stages are inaccessible to ship-based surveys. This is ...

    • 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 ...

    • Twilight foraging enables European shags to survive the winter across their latitudinal range 

      Moe, Børge; Daunt, Francis; Bråthen, Vegard Sandøy; Barrett, Robert; Ballesteros, Manuel; Bjørnstad, Oskar; Bogdanova, Maria I.; Dehnhard, Nina; Erikstad, Kjell E.; Follestad, Arne; Gíslason, Sindri; Hallgrimsson, Gunnar Thor; Lorentsen, Svein-Håkon; Newell, Mark; Petersen, Aevar; Phillips, Richard A.; Ragnarsdóttir, Sunna Björk; Reiertsen, Tone Kristin; Åström, Jens; Wanless, Sarah; Anker-Nilssen, Tycho (Peer reviewed; Journal article, 2021)
      Species breeding at high latitudes face a significant challenge of surviving the winter. Such conditions are particularly severe for diurnal marine endotherms such as seabirds. A critical question is therefore what behavioural ...
