      Global warming is a nonlinear process, and temperature may increase in a stepwise manner. Periods of abrupt warming can trigger persistent changes in the state of ecosystems, also called regime shifts. The responses of ...

    • Feather Corticosterone Levels on Wintering GroundsHave No Carry-Over Effects on Breeding among ThreePopulations of Great Skuas (Stercorarius skua) 

      Bourgeon, Sophie; Leat, Eliza H. K.; Magnusdottir, Ellen; Furness, Robert W.; Strøm, Hallvard; Petersen, Aevar; Gabrielsen, Geir W.; Hanssen, Sveinn Are; Bustnes, Jan Ove (Peer reviewed; Journal article, 2014)
      Environmental conditions encountered by migratory seabirds in their wintering areas can shape their fitness. However, the underlying physiological mechanisms remain largely unknown as birds are relatively inaccessible ...

    • Multiple Stressors in a Top Predator Seabird:Potential Ecological Consequences ofEnvironmental Contaminants, PopulationHealth and Breeding Conditions 

      Bustnes, Jan Ove; Bourgeon, Sophie; Leat, Eliza H. K.; Magnusdottir, Ellen; Strøm, Hallvard; Hanssen, Sveinn Are; Petersen, Aevar; Gabrielsen, Geir W.; Furness, Robert W. (Peer reviewed; Journal article, 2015)
