Rapid population increase in an introduced muskox population, West Greenland
In 1962 and 1965, 27 (13 and 14) muskox yearlings were translocated from East Greenland (71°N) to the Angujaartorfiup Nunaa range in West Greenland (67°N). Angujaartorfiup Nunaa is a 6600 km2 icefree, continental area where caribou are indigenous. The climate is strictly continental with a minimum o...
