We review seven Arctic and four subarctic marine mammal species, their habitat requirements, and evidence for biological and demographic responses to climate change. We then describe a pan-Arctic quantitative index of species sensitivity to climate change based on population size, geographic range, habitat specificity, diet diversity, migration, site fidelity, sensitivity to changes in sea ice, sensitivity to changes in the trophic web, and maximum population growth potential (R(max)).

TLDR
An overview of prey preferences of seven core Arctic marine mammal species (AMM) and four non-core species on a pan-Arctic scale with regional examples is provided and three potential scenarios of large-scale biotic change are suggested, based on published observations and predictions of environmental change.

TLDR
Impacts of climate change on ice-related species categories are categorized for: ice-obligate species that rely on sea ice platforms, ice-associated species that are adapted to sea ice-dominated ecosystems, and seasonally migrant species for which sea ice can act as a barrier. Expand
Climate Change Impacts on Seals and Whales in the North Atlantic Arctic and Adjacent Shelf Seas
TLDR
In a warmer Arctic, endemic marine mammal species will face extreme levels of habitat change, most notably a dramatic reduction in sea ice, and if species are fixed in traditional spatial and temporal cycles, and are unable to shift them within decadal time scales, some populations will go extinct.

Examining the Health and Energetic Impacts of Climate-Induced Prey Shifts on Beluga Whales Using Community-Based Research
The loss of seA ice due to climAte chAnge is altering the structure of Arctic marine ecosystems. Sea ice plays a critical role in the life histories of many Arctic marine mammals that use ice asExpand
Arctic Marine Mammals
Abstract Arctic marine mammals range widely, serve as biological indicators, occupy areas rich in natural resources, and are an important subsistence resource. Eleven species of Arctic marine mammalsExpand
Arctic marine mammal population status, sea ice habitat loss, and conservation recommendations for the 21st century

  • Geography, Medicine

  • 2015
TLDR
Recommendations for effective AMM conservation are maintained and improved by local, federal, and international partners; recognize spatial and temporal variability in AMM subpopulation response to climate change; implement monitoring programs with clear goals; mitigate cumulative impacts of increased human activity; and recognize the limits of current protected species legislation.

Marine mammals as ecosystem sentinels
Abstract The earth's climate is changing, possibly at an unprecedented rate. Overall, the planet is warming, sea ice and glaciers are in retreat, sea level is rising, and pollutants are accumulatingExpand

TLDR
A review of published studies revealed that population subdivision, dispersal, and gene flow in Arctic marine mammals was shaped primarily by evolutionary history, geography, sea ice, and philopatry to predictable, seasonally available resources. Expand
The impact of rising sea temperatures on an Arctic top predator, the narwhal
TLDR
The hypothesis that warming ocean waters will restrict the habitat range of the narwhal is supported, suggesting that narwhals from Mideast and Southeast Greenland may be under pressure to abandon their traditional habitats due to ocean warming, and consequently either migrate further North or locally go extinct.

Variation in habitat use of Beaufort Sea polar bears
TLDR
Analysis of habitat selection patterns of subadult male and female and adult female polar bears in the Southern Beaufort Sea population from 2007 to 2011 found that polar bears displayed broad similarities in seasonal habitat selection by using nearshore areas in winter/spring and ranging farther offshore into the multiyear ice in summer/autumn.

Abstract Some of the most pronounced ecological responses to climatic warming are expected to occur in polar marine regions, where temperature increases have been the greatest and sea ice provides aExpand

Recent analyses have revealed trends over the past 20-30 years of decreasing sea ice extent in the Arctic Ocean coincident with warming trends. Such trends may be indicative of the polarExpand
Possible Effects of Climate Warming on Selected Populations of Polar Bears ( Ursus maritimus ) in the Canadian Arctic
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 progressively earlier breakupExpand

Pinniped diversity is greatest in seasonally ice-covered seas where the risk of predation is minimised. In recent decades, the thickness and extent of seasonal ice cover has decreased in the Arctic,Expand

Polar bears live in high-latitude environments characterized by cyclic variation in form and extent of sea ice. From 1991 to 1995, we used radio telemetry and monthly satellite images to compareExpand
Polar Bears in a Warming Climate1
TLDR
It is unlikely that polar bears will survive as a species if the sea ice disappears completely as has been predicted by some, but the effects of climate change are likely to show large geographic, temporal and even individual differences and be highly variable, making it difficult to develop adequate monitoring and research programs.
