We review seven Arctic and four subarctic marine mammal species, their habitat
requirements, and evidence for biological and demographic responses to climate change …

Climate change is taking place more rapidly and severely in the Arctic than anywhere on the
globe, exposing Arctic vertebrates to a host of impacts. Changes in the cryosphere dominate …

Arctic sea ice has changed dramatically, especially during the last decade and continued
declines in extent and thickness are expected for the decades to come. Some ice-associated …

Evolutionary selection has refined the life histories of seven species (three cetacean
[narwhal, beluga, and bowhead whales], three pinniped [walrus, ringed, and bearded seals] …

The 2008 IUCN (International Union for Conservation of Nature) review of the status of the
world's mammals identified marine mammals (pinnipeds, cetaceans, sirenians, and the …

The shrinking of Arctic-wide September sea ice extent is often cited as an indicator of
modern climate change; however, the timing of seasonal sea ice retreat/advance and the …

Climate change is now known to be affecting the oceans. It is widely anticipated that impacts
on marine mammals will be mediated primarily via changes in prey distribution and …

We used quantitative fatty acid signature analysis (QFASA) to examine the diets of 1738
individual polar bears (Ursus maritimus) sampled across the Canadian Arctic over a 30‐year …

Polar bears depend on sea ice for survival. Climate warming in the Arctic has caused
significant declines in total cover and thickness of sea ice in the polar basin and …

The Western Antarctic Peninsula (WAP) is a biologically rich area supporting large standing
stocks of krill and top predators (including whales, seals and seabirds). Physical forcing …
