• There has been a dramatic decrease in sea-ice extent in the Arctic; further reduction is expected in the future. Species such as the Polar Bear, Narwhal and Ringed Seals depend on sea ice for foraging, birthing and predator evasion
• Loss of sea-ice extent in Western Hudson Bay is correlated to weakened body condition of Polar Bears and the decline in their populations

• High Arctic species populations have decreased by an average of 26% between 1970 and 2004

• Sub Arctic species populations peaked in the mid-1980s and have been on the decline ever since
• There has been a dramatic decrease in sea-ice extent in the High Arctic; further reduction is expected in the future. Species such as the polar bear, narwhal and ringed seals depend on sea ice for foraging, birthing and predator evasion

• Low Arctic species populations have increased between 1970 and 2004
• Sub Arctic species populations remained stable between 1970 and 2004
• The confidence intervals show that the overall increase in vertebrate abundance was between 2% and 32%

• 80% of global goose populations are found in the Arctic

Fish

• 28% of the global commercial fish catch is from Arctic waters

• For many fish, population changes depend on sea temperature fluctuations

Whales

• Alaskan Bowhead Whale populations have increased because hunting pressure has been removed
