...Alicia Borque-Espinosa; Karyn D. Rode; Diana Ferrero-Fernández; Anabel Forte; Romana Capaccioni-Azzati; Andreas Fahlman ABSTRACT Walruses rely on sea-ice to efficiently forage and rest between diving bouts while maintaining proximity to prime foraging habitat. Recent declines in summer sea ice have...
