Supplementary Figures S1-S3 from Environmental drivers of population-level variation in the migratory and diving ontogeny of an Arctic top predator
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 of both physiological and foraging skill development. Here, we assess how migr...

The development of migratory strategies that enable juveniles to survive to sexual maturity is critical for species that exploit seasonal niches.
