• Consequences of cross-season demographic correlations for population viability 

      Layton-Matthews, Kate; Reiertsen, Tone Kristin; Erikstad, Kjell E.; Anker-Nilssen, Tycho; Daunt, Francis; Wanless, Sarah; Barrett, Robert; Newell, Mark A; Harris, Mike P. (Peer reviewed; Journal article, 2023)
      Demographic correlations are pervasive in wildlife populations and can represent important secondary drivers of population growth. Empirical evidence suggests that correlations are in general positive for long-lived ...
    • Individual migration strategy fidelity but no habitat specialization in two congeneric seabirds 

      Merkel, Benjamin; Descamps, Sebastien; Yoccoz, Nigel; Grémillet, David; Daunt, Francis; Erikstad, Kjell E; Ezhov, Aleksey V.; Harris, Mike P.; Gavrilo, Maria; Lorentsen, Svein Håkon; Reiertsen, Tone Kristin; Steen, Harald; Systad, Geir Helge Rødli; Þórarinsson, Þorkell Lindberg; Wanless, Sarah; Strøm, Hallvard (Peer reviewed; Journal article, 2020)
      Abstract Aim: In migratory species, individuals often use fixed and individual-specific migration strategies, which we term individual migration strategy fidelity (IMSF). Our goal was to test if guillemots have flexible ...
    • Metapopulation regulation acts at multiple spatial scales: Insights from a century of seabird colony census data 

      Jeglinski, Jana W.E.; Wanless, Sarah; Murray, Stuart; Barrett, Robert; Gardarsson, Arnthor; Harris, Mike P.; Dierschke, Jochen; Strøm, Hallvard; Lorentsen, Svein-Håkon; Matthiopoulos, Jason (Peer reviewed; Journal article, 2023)
      Density-dependent feedback is recognized as important regulatory mechanisms of population size. Considering the spatial scales over which such feedback operates has advanced our theoretical understanding of metapopulation ...
    • Multi-colony tracking of two pelagic seabirds with contrasting flight capability illustrates how windscapes shape migratory movements at an ocean-basin scale 

      Amelineau, Francoise; Tarroux, Arnaud; Lacombe, Simon; Bråthen, Vegard Sandøy; Descamps, Sebastien; Ekker, Morten; Fauchald, Per; Johansen, Malin; Moe, Børge; Anker-Nilssen, Tycho; Bogdanova, Maria I.; Bringsvor, Ingar S.; Chastel, Olivier; Christensen-Dalsgaard, Signe; Daunt, Francis; Dehnhard, Nina; Erikstad, Kjell E.; Ezhov, Aleksey; Gavrilo, Maria; Hansen, Erpur S.; Harris, Mike P.; Helgason, Halfdan Helgi; Langset, Magdalene; Léandri-Breton, Don-Jean; Lorentsen, Svein-Håkon; Merkel, Benjamin; Newell, Mark; Olsen, Bergur; Reiertsen, Tone Kristin; Systad, Geir Helge Rødli; Thorarinsson, Thorkell L.; Åström, Jens; Strøm, Hallvard (Peer reviewed; Journal article, 2023)
      Migration is a common trait among many animals allowing the exploitation of spatiotemporally variable resources. It often implies high energetic costs to cover large distances, for example between breeding and wintering ...
    • A new biologging approach reveals unique flightless molt strategies of Atlantic puffins 

      Darby, Jamie; Harris, Mike P.; Wanless, Sarah; Quinn, John; Bråthen, Vegard Sandøy; Fayet, Annette; Clairbaux, Manon; Hart, Tom; Guillford, Tim; Freeman, Robin; Jessopp, Mark (Peer reviewed; Journal article, 2022)
      Animal- borne telemetry devices provide essential insights into the life- history strate -gies of far- ranging species and allow us to understand how they interact with their environment. Many species in the seabird family ...
    • Ocean-wide drivers of migration strategies and their influence on population breeding performance in a declining seabird 

      Fayet, Annette L.; Freeman, Robin; Anker-Nilssen, Tycho; Diamond, Antony; Erikstad, Kjell E; Fifield, Dave; Fitzsimmons, Michelle G; Hansen, Erpur Snær; Harris, Mike P.; Jessopp, Mark; Kouwenberg, Amy-Lee; Kress, Steve; Mowat, Stephen; Perrins, Chris M.; Petersen, Aevar; Petersen, Ib K.; Reiertsen, Tone; Robertson, Gregory J.; Shannon, Paula; Sigurðsson, Ingvar A.; Shoji, Akiko; Wanless, Sarah; Guilford, Tim (Journal article; Peer reviewed, 2017)
      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 ...
