Document Summary

Shrews, less than 2 hours after eating. Small animals & birds, 3 - 6 hours. Some rodents & small birds (white-crowned sparrow), become hyperactive: in a thermoneutral environment, without physical or psychological stress. 0. 1 kg animal = bmr 12. 4 kcal/day = 124 kcal/kg. 10 kg animal = bmr 394 kcal/day = 39. 4 kcal/kg. ** 100 kg animal does not need twice as much energy as 50 kg animal. Starvation (prolonged, slow weight loss with fat as major energy source) Bmr correlates more closely with bodyweight0. 75 (x0. 75) than with bodyweight (x) Smaller animal has a higher energy requirement for basal metabolism per unit of body weight, than a larger animal. Ex. population of 100 small animals ~ 0. 1 kg bw total bw 10 kg = need 1240 kcal/day for bmr. Sleep)ng = (cid:494)metabolic rate(cid:495) 7-28% lower than waking bmr. W)nter = bmr may be lower or bmr may be (igher.
