^a Values predicted based on data on resting metabolic rate/oxygen uptake in newborn reindeer (Markussen et al. 1985), assuming similar proportionality between oxygen uptake and Vmin and fa, respectively, in newborn as in mature reindeer. Data on resting metabolic rate of mature reindeer from Nilssen et al. (1985)
