In a warmer Arctic, endemic marine mammal species face extreme levels of habitat change, which is expected to result in dramatic reductions in sea ice dependent species. Extirpations of some marine mammal stocks are likely.
1 Μαρ 2008 · Here I review the evolutionary history of the “core” Arctic marine mammals ( Huntington and Moore 2008 ), namely the polar bear (Ursus maritimus), walrus (Odobenus rosmarus), bearded seal (Erignathus barbatus), harp seal (Pagophilus groenlandica), and ringed seal (Phoca hispida), as well as the bowhead whale (Balaena mysticetus) and the monodont...
Polar bears, the iconic species of the Arctic, are the marine mammal that causes the most concern with regards to climate change and sea ice loss. The most ice-bound of the marine mammals, polar bears migrate hundreds and thousands of miles across sea ice.
1 Ιαν 2018 · Eleven species of Arctic marine mammals are highly associated with, or dependent on, sea ice for key aspects of their life history including foraging, reproduction, and movement. Approximately 24 other species forage in the Arctic seasonally.

Arctic marine mammals are well adapted to the vagaries, fluctuations, and natural cycles of the Arctic Ocean. Climate change is impacting sea ice, posing a risk to Arctic marine food webs and ice-dependent species such as Arctic cod. 2 Large species are more impacted by disturbance and changes in the Arctic Ocean since they migrate long ...
