In hibernating black bears, changes in metabolic rate and core body temperature occur independently. Do bears really hibernate? Their high body temperature during winter dormancy has raised some doubt about this behavior, as it is unlike the pronounced decreases observed in small mammals that enter this nonactive state. On page 906 of this issue, Tøien et al. (1) show that bears do indeed hibernate. Through continuous measurement of oxygen consumption, body temperature, and heart, muscle, and… Expand
