      Climate change affects timing of reproduction in many bird species, but few studies have investigated its influence on annual reproductive output. Here, we assess changes in the annual production of young by female breeders ...
    • 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 ...
    • The stress hormone corticosterone in a marine top predatorreflects short-term changes in food availability 

      Barrett, Robert; Erikstad, Kjell E; Sandvik, Hanno; Myksvoll, Mari Skuggedal; Jenni-Eiermann, Susi; Kristensen, Ditte Lyngbo; Moum, Truls; Reiertsen, Tone; Vikebø, Frode Bendiksen (Journal article; Peer reviewed, 2015)
      In many seabird studies, single annual proxies of prey abundance have been used to explain variability in breeding performance, but much more important is probably the timing of prey availability relative to the breeding ...
    • There is more to climate than the North Atlantic Oscillation: a new perspective from climate dynamics to explain the variability in population growth rates of a long-lived seabird 

      Mesquita, Michel d. S.; Erikstad, Kjell E; Sandvik, Hanno; Reiertsen, Tone; Barrett, Robert; Anker-Nilssen, Tycho; Hodges, Kevin I.; Bader, Jürgen (Journal article; Peer reviewed, 2015)
      Predicting the impact of global climat echange on the biosphere has become one of the most important efforts in ecology. Ecosystems worldwide are changing rapidly as a consequence of global warming, yet our understanding ...
    • 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 ...
