Walrus Used and Available Resource Units for Northeast Chukchi Sea, 2008-2012 Walrus Used and Available Resource Units for Northeast Chukchi Sea, 2008-2012
Sea ice loss represents a stressor to the Pacific walrus (Odobenus rosmarus divergens), which feeds on benthic macroinvertebrates in the Bering and Chukchi seas. However, no studies have examined the effects of sea ice on foraging walrus space use patterns. Thus, we examined walrus foraging resource selection as a function of proximity to resting substrates and prey biomass with a...
