claimFemale walruses and young animals, which previously remained year-round near sea ice over the shallow shelf of the Pacific Arctic, now move to land-based haul-out sites along the coasts of Alaska and Russia between feeding trips due to the northward retreat of sea ice, as reported by Jay et al. (2012).
