Studies of predation traditionally focus on how predators influence prey communities and prey population oscillations via mortality. Studies carried out for nearly 40 years in one place have enabled us to evaluate the gener- ality of this focus. Early observations in one high-altitude, rocky-bottom

When entering torpor, oxygen consumption decreased prior to the decline in body temperature for all 15 marmots used in this study. Most mean Q1o values were greater than 3.0, which supports metabolic inhibition rather than passive decline of metabolism because of the drop in body temperature. Change
