Plant and animal range shifts and population changes
Canadian Arctic
Caribou die-offs. Peary caribou have declined from 24,000 in 1961 to perhaps as few as 1,100 in 1997, mostly because of major die-offs that have occurred in recent years after heavy snowfalls and freezing rain covered the animals' food supply.
