    • Climate change, marine resources and a small Chilean community: making the connections 

      van Leeuwen, Sonja M.; Salgado, Hugo; Bailey, Jennifer L.; Beecham, Jonathan; Iriarte, José L.; García-García, Luz; Thorpe, Robert (Peer reviewed; Journal article, 2021)
      Climate change is affecting large-scale oceanic processes. How and when these changes will impact those reliant on marine resources is not yet clear. Here we use end-to-end modeling to track the impacts of expected changes ...

    • 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 ...

    • The effects of nutritional state, sex and body size on the marine migration behaviour of sea trout 

      Eldøy, Sindre Håvarstein; Bordeleau, Xavier; Lawrence, M. J.; Thorstad, Eva B.; Finstad, Anders Gravbrøt; Whoriskey, Frederick G.; Crossin, Glenn T; Cooke, Steven J.; Aarestrup, Kim; Rønning, Lars; Sjursen, Aslak Darre; Davidsen, Jan Grimsrud (Peer reviewed; Journal article, 2021)
      The sea trout (anadromous brown trout Salmo trutta) displays extensive among-individual variation in marine migration behaviour. We studied the migration behaviour of 286 sea trout (27-89 cm) tagged with acoustic transmitters ...

    • 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 ...

    • Phases of microalgal succession in sea ice and the water column in the Baltic Sea from autumn to spring 

      Enberg, Sara; Majaneva, Markus; Autio, R; Blomster, Jaanika; Rintala, Janne‐Markus (Journal article; Peer reviewed, 2018)
      The phytoplankton biomass in the Baltic Sea is low during the cold-water season (October to May) compared to the warm-water season (June to September). However, the sea ice is a habitat for diverse assemblages in polar and ...

    • Prevailing weather conditions and dietcomposition affect chick growth and survival in the black-legged kittiwake 

      Christensen-Dalsgaard, Signe; May, Roelof Frans; Barrett, Robert; Langset, Magdalene; Sandercock, Brett; Lorentsen, Svein Håkon (Journal article; Peer reviewed, 2018)
      To identify priorities for management of seabirds during the breeding season, it is important to understand the ecological mechanisms driving chick growth and survival. In this study, we examined the effects of diet and ...

    • 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 ...
