摘要: We investigated overwinter energetics of grizzly bears (Ursus arctos horribilis) by measuring oxygen uptake 2 in a simulated den. Standard metabolic rate averaged 68.0 ? 2.8 (SD)% predicted values. The lowest observed rates were further reduced to <50% expected Grizzly have the potential triple survival time on given level energy stores through reduction
