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.
