Environmental drivers of population-level variation in the migratory and diving ontogeny of an Arctic top predator
Grecian, W. James; Stenson, Garry B.; Biuw, Martin; Boehme, Lars; Folkow, Lars; Goulet, Pierre J.; Jonsen, Ian D.; Malde, Aleksander; Nordøy, Erling Sverre; Rosing-Asvid, Aqqalu; Smout, Sophie (Peer reviewed; Journal article, 2022)The development of migratory strategies that enable juveniles to survive to sexual maturity is critical for species that exploit seasonal niches. For animals that forage via breath-hold diving, this requires a combination ... -

Multi-decadal trends in biomarkers in harp seal teeth from the North Atlantic reveal the influence of prey availability on seal trophic position
de la Vega, Camille; Kershaw, Joanna; Stenson, Garry B.; Frie, Anne Kirstine Højholt; Biuw, Martin; Haug, Tore; Norman, Louisa; Mahaffey, Claire; Smout, Sophie; Jeffreys, Rachel M. (Peer reviewed; Journal article, 2023)Arctic food webs are being impacted by borealisation and environmental change.
