...Enrico L. Rezende; Kimberly A. Hammond; Mark A. Chappell SUMMARY We studied metabolic and organ mass responses to thermal acclimation (7 weeks at 5°C or 23°C) in deer mice, Peromyscus maniculatus . Cold acclimation resulted in significantly higher maximal oxygen consumption in thermogenesis (V̇ O 2...

... of the habitat(K), respectively. Maximal oxygen consumption was highly repeatable over a period of 8 weeks in both control and cold-acclimated mice, as previously shown for V̇ O 2 max in Peromyscus ( Hayes,1989 ; Hayes and Chappell,1990 ). This means that an individual's relative performance...

... for mammals, their basal metabolic rate (BMR) and maximal oxygen consumption in exercise( V̇ O 2 max ) and thermogenesis( V̇ O 2 sum )increased as power functions of mass. Age did not affect BMR, but we found abrupt decreases in growth rate, V̇ O 2 max and V̇ O 2 sum at approximately 485 days of age...
