Metabolic rates of four resting, post-absorptive male adult summer- and winter-adapted captive arctic foxes (Alopex lagopus) were recorded. [...] Key Result Basal metabolic rates (BMR) varied seasonally with a 36% increase from winter to summer, while body mass was reduced by 17% in the same period. The lower critical temperature (T1c) of the winter-adapted arctic fox was estimated to −7°C, whereas Tlc during summer was 5°C.Expand
