Energy expenditure in reindeer walking on roads and on tundra

White, R. G., Yousef, M. K.·1978·Canadian Journal of Zoology

Abstract

The oxygen consumption, VO 2, of two adult female reindeer (Rangifer tarandus L.) was measured while walking on roads, wet and dry tundra, and on level ground and gradients of 5 and 9%. The oxygen cost of horizontal walking on the road (S, 0.099 ± 0.009 ml O 2/g per kilometre) was 14% higher than that for the interspecies line for mammals given by S = 8.46 W−0.4, where W is body weight (grams). S increased significantly to 0.112 and 0.137 for horizontal walking on dry and wet tundra, respectively. In two human subjects, the oxygen cost of horizontal walking on roads (S, 0.096 ± 0.013) was similar to reindeer; however, on dry tundra S increased 40% more than in reindeer. The mechanical efficiency of reindeer walking up 5 and 9% grades was 50 and 32%, respectively, and the VO 2 in walking up a 5% gradient was 1.4 times greater than walking down; the VO 2 in walking up a 9% gradient was 1.9 times greater than walking down. Resting metabolism of the two reindeer used in walking experiments varied markedly (120–204 kcal (502–854 kJ)/kg 0.75 per day); for a group of four adult female reindeer taken from late summer grazing, resting metabolism was 125 ± 8 kcal (523 kJ)/kg 0.75 per day, which was similar to previous estimates for reindeer.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
