      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 ...
    • 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, 2015)
      Environmental contaminants may have impacts on reproduction and survival in wildlife populations suffering from multiple stressors. This study examined whether adverse effects of persistent organic pollutants (POPs) ...
    • Ocean-wide drivers of migration strategies and their influence on population breeding performance in a declining seabird

      Which factors shape animals’ migration movements across large geographical scales, how different migratory strategies emerge between populations, and how these may affect population dynamics are central questions in ...
    • What’s the catch with lumpsuckers? A North Atlantic study of seabird bycatch in lumpsucker gillnet fisheries 

      Christensen-Dalsgaard, Signe; Anker-Nilssen, Tycho; Crawford, Rory; Bond, Alexander; Sigurðsson, Guðjón Már; Glemarec, Gildas; Snær Hansen, Erpur; Kadin, Martina; Kindt-Larsen, Lotte; Mallory, Mark; Ravn Merkel, Flemming; Petersen, Aevar; Provencher, Jennifer; Bærum, Kim Magnus (Peer reviewed, 2019)
      Worldwide, incidental bycatch in fisheries is a conservation threat to many seabird species. Although knowledge on bycatch of seabirds has increased in the last decade, most stems from longline fisheries and the impacts ...
