Centennial relationships between ocean temperature and Atlantic puffin production reveal shifting decennial trends
Hansen, Erpur S.; Sandvik, Hanno; Erikstad, Kjell E.; Yoccoz, Nigel; Anker-Nilssen, Tycho; Bader, Jürgen; Descamps, Sebastien; Hodges, Kevin; Mesquita, Michel d. S.; Reiertsen, Tone Kristin; Varpe, Øystein (Peer reviewed; Journal article, 2021)The current warming of the oceans has been shown to have detrimental effects for a number of species. An understanding of the underlying mechanisms may be hampered by the non-linearity and non-stationarity of the relationships ... -

Yet, ... -
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 species, ... -
Eyes on the future: buffering increased costs of incubation by abandoning offspring
Hanssen, Sveinn Are; Erikstad, Kjell E.; Sandvik, Hanno; Tveraa, Torkild; Bustnes, Jan Ove (Peer reviewed; Journal article, 2023)Life history theory states that the resources invested in current reproduction must be traded off against resources needed for survival and future reproduction. Long-lived organisms have a higher residual reproductive value ... -

Raising offspring increases ageing: Differences in senescence among three populations of a long-lived seabird, the Atlantic puffin
Landsem, Terje Lorentzen; Yoccoz, Nigel Gilles; Layton-Matthews, Kate; Hilde, Christoffer Høyvik; Harris, Michael P; Wanless, Sarah; Daunt, Francis; Reiertsen, Tone Kristin; Erikstad, Kjell E.; Anker-Nilssen, Tycho (Peer reviewed; Journal article, 2023)1. Actuarial senescence, the decline of survival with age, is well documented in the wild. Rates of senescence vary widely between taxa, to some extent also between sexes, with the fastest life histories showing the highest ... -
Strong migratory connectivity across meta-populations of sympatric North Atlantic seabirds
Merkel, Benjamin; Descamps, Sebastien; Yoccoz, Nigel; Grémillet, David; Fauchald, Per; Danielsen, Jóhannis; Daunt, Francis; Erikstad, Kjell E.; Ezhov, Aleksey V.; Harris, Mike P.; Gavrilo, Maria; Lorentsen, Svein-Håkon; Reiertsen, Tone Kristin; Systad, Geir Helge Rødli; Thórarinsson, Thorkell Lindberg; Wanless, Sarah; Strøm, Hallvard (Peer reviewed; Journal article, 2021)Identifying drivers of population trends in migratory species is difficult, as they can face many stressors while moving through different areas and environments during the annual cycle. To understand the potential of ... -
