As Arctic climate changes and climate/sea-ice/ecotone boundaries shift, we increasingly observe diverse responses by people and animals to environmental stress. The emerging record may be best approached as a series of localized human-animal disequilibria, also known as "crashes", interpreted from different angles by population biologists, Arctic indigenous people, and anthropologists, rather than top-down climate-induced collapses. Besides six keystone polar game species, this book examines the population status of polar bear and narwhal in the Canadian Arctic, Pribilof Island fur seal, and Atlantic cod in Greenland. The end result is a research filled narrative full of diverse historical, archaeological, evolutionary, as well as cultural and spiritual perspectives on these Arctic "crashes."
