referenceA 2016 study by Hamilton et al. examined the use of glacial refugia by ringed seals (Pusa hispida) following a regional sea-ice collapse in the Arctic.

claimYoung ringed seals must travel farther north to reach sea ice due to changing environmental conditions, as noted by Hamilton et al. (2016; 2019).

referenceVon Duyke et al. (2020) studied ringed seal (Pusa hispida) seasonal movements, diving, and haul-out behavior in the Beaufort, Chukchi, and Bering Seas from 2011 to 2017.

referenceFreitas, C., Kovacs, K. M., Ims, R. A., and Lydersen, C. (2008) published 'Predicting habitat use by ringed seals (Phoca hispida) in a warming Arctic' in Ecological Modelling, volume 217, pages 19–32, modeling the habitat use of ringed seals in the context of a warming Arctic.

referenceLone et al. (2019) observed that ringed seals (Pusa hispida) select specific summer habitats within the drifting sea ice of the northern Barents Sea.

referenceOgloff et al. (2021) studied the long-distance movements and associated diving behaviour of ringed seals (Pusa hispida) in the eastern Canadian Arctic.

referenceA 2017 study by Hamilton et al. analyzed climate change impacts on coastal space use by polar bears and ringed seals in an Arctic predator-prey system.

referenceJ. A. Crawford, L. T. Quakenbush, and J. J. Citta compared the diet, condition, and productivity of ringed and bearded seals in the Alaskan Bering and Chukchi seas between historical (1975–1984) and recent (2003–2012) periods.

claimAdult ringed seals in coastal areas around Svalbard have restricted movement patterns and smaller home ranges compared to a few decades ago, necessitating increased foraging effort, according to Hamilton et al. (2016; 2019).

claimChanges in sea-ice distribution, specifically summer sea-ice edges occurring farther north, have caused ringed seals in the Barents Region to undertake longer migrations and have altered their foraging behavior.

claimRinged seals (Pusa hispida) have maintained similar start times for their summer foraging migrations to preferred sea-ice concentrations, but they now require longer travel distances compared to previous decades.

referenceA 2015 study by Hamilton et al. documented behavioral responses of ringed seals to declining Arctic sea-ice.
