The 1953 Lemming Emigration at Point Barrow, Alaska

Résumé

Contains account of observations and counts made at the Barrow base camp, an 80-acre area, and on the adjacent tundra on the mass movements of the brown lemming. Age composition; male-female ratio; condition of digestive tract, adrenals, reproductive organs, etc., were studied. Causes of this emigration (changes in food supply and cover) as well as similar movements earlier in this region and in Scandinavia are discussed.
