      Reproductive timing in many taxa plays a key role in determining breeding productivity, and is often sensitive to climatic conditions. Current climate change may alter the timing of breeding at different rates across trophic levels, potentially resulting in temporal mismatch between the resource requirements of predators and their prey. This is of particular concern for higher-trophic-level organisms, ...

    • 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 (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-10-14)
      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 on seabird population dynamics through increased mortality. The intensity and persistence of extreme events are forecasted to increase with global warming. As shared conditions ...

    • Multicolony tracking reveals the winter distribution of a pelagic seabird on an ocean basin scale 

      Frederiksen, Morten; Moe, Børge; Daunt, Francis; Phillips, Richard A.; Barrett, Robert; Bogdanova, Maria I; Boulinier, Thierry; Chardine, John W; Chastel, Olivier; Chivers, Lorraine S; Christensen-Dalsgaard, Signe; Clémet-Chastel, Céline; Colhoun, Kendrew; Freeman, Robin; Gaston, Anthony J; González-Solís, Jacob; Goutte, Aurélie; Grémillet, David; Guilford, Tim; Jensen, Gitte H; Krasnov, Yuri V.; Lorentsen, Svein-Håkon; Mallory, Mark L; Newell, Mark; Olsen, Bergur; Shaw, Deryk; Steen, Harald; Strøm, H.; Systad, Geir Helge; Thórarinsson, Thorkell L; Anker-Nilssen, Tycho (Journal article; Tidsskriftartikkel; Peer reviewed, 2011-11-26)
      Aim An understanding of the non-breeding distribution and ecology of migratory species is necessary for successful conservation. Many seabirds spend the nonbreeding season far from land, and information on their distribution during this time is very limited. The black-legged kittiwake, Rissa tridactyla, is a widespread and numerous seabird in the North Atlantic and Pacific, but breeding ...

    • 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 (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-10-14)
      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 strategies such species adopt to maximise survival probability. We tested 3 hypotheses: (1) they migrate to lower latitudes to exploit longer day length (‘sun-chasing’), (2) ...

    • Year-round distribution of Northeast Atlantic seabird populations: applications for population management and marine spatial planning 

      Fauchald, Per; Amélineau, Françoise; Bråthen, Vegard Sandøy; Descamps, Sebastien; Ekker, Morten; Helgason, Halfdan Helgi; Johansen, Malin; Merkel, Benjamin; Moe, Børge; Åström, Jens; Bjørnstad, Oskar; Chastel, Olivier; Christensen-Dalsgaard, Signe; Danielsen, Jóhannis; Daunt, Francis; Dehnhard, Nina; Erikstad, Kjell E.; Ezhov, Alexey; Gavrilo, Maria; Hallgrimsson, Gunnar Thor; Hansen, Erpur Snær; Harris, Mike; Helberg, Morten; Jónsson, Jón Einar; Kolbeinsson, Yann; Krasnov, Yuri V.; Langset, Magdalene; Lorentsen, Svein-Håkon; Lorentzen, Erlend; Newell, Mark; Olsen, Bergur; Reiertsen, Tone Kristin; Systad, Geir Helge Rødli; Thompson, Paul; Thórarinsson, Thorkell Lindberg; Wanless, Sarah; Wojczulanis-Jakubas, Katarzyna; Strøm, Hallvard (Journal article; Tidsskriftartikkel; Peer reviewed, 2021)
      Tracking data of marine predators are increasingly used in marine spatial management. We developed a spatial data set with estimates of the monthly distribution of 6 pelagic seabird species breeding in the Northeast Atlantic. The data set was based on year-round global location sensor (GLS) tracking data of 2356 adult seabirds from 2006−2019 from a network of seabird colonies, data describing the ...
