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 ... -
Differential reproductive responses to stress reveal the role of life-history strategies within a species
Schultner, Jannik; Kitaysky, Alexander S.; Gabrielsen, Geir W.; Hatch, Scott; Bech, Claus (Journal article; Peer reviewed, 2013)Life-history strategies describe that ‘slow’- in contrast to ‘fast’-living species allocate resources cautiously towards reproduction to enhance survival. Recent evidence suggests that variation in strategies exists not ... -
Migration and stress during reproduction govern telomere dynamics in a seabird
Schultner, Jannik; Moe, Børge; Chastel, Olivier; Bech, Claus; Kitaysky, Alexander S. (Journal article; Peer reviewed, 2014)Changes in telomere length are believed to reflect changes in physiological state and life expectancy in animals. However, much remains unknown about the determinants of telomere dynamics in wild populations, and specifically ... -
Multicolony tracking reveals potential threats to little auks wintering in the North Atlantic from marine pollution and shrinking sea ice cover
Fort, Jérôme; Moe, Børge; Strøm, Hallvard; Grémillet, David; Welcker, Jorg; Schultner, Jannik; Jerstad, Kurt; Johansen, Kasper L.; Phillips, Richard A.; Mosbech, Anders (Journal article; Peer reviewed, 2013)Aim Extensive development of human activities in combination with ocean warming is rapidly modifying marine habitats in the Arctic and North Atlantic regions. To understand the potential impacts on marine biodiversity, ... -
Resource allocation under stress: mechanisms and strategies in a long-lived bird
Schultner, Jannik (Doktoravhandlinger ved NTNU, 1503-8181; 2014:25, Doctoral thesis, 2014)The marine environment is currently undergoing critical modification in the wake of global climate change. Marine animals are, consequently, expected to experience increasing periods of nutritionally stressful conditions. ...
