Abstract	While heart rate (fH) has been used as an indicator of energy expenditure, quantitative data showing the relationship between these variables are only available for normothermic animals. To determine whether fH also predicts oxygen consumption ( ) during torpor, we simultaneously measured , fH and subcutaneous body temperature (Tsub) of a hibernator, Gould's long-eared bats (Nyctophilus gouldi, 9 g, N=18), at ambient temperatures (Ta) between 0 and 25°C. At rest, fH of normothermic resting bats was negatively correlated with Ta, with maximum fH of 803 beats min(-1) (Ta=5°C). During torpor, the relationship between fH and Ta was curvilinear, and at low Tsub (~6°C), fH fell to a minimum average of 8 beats min(-1). The minimum average values for both and fH in torpor reported here were among the lowest recorded for bats. The relationship between fH and was significant for both resting (r(2)=0.64, P<0.001) and torpid bats (r(2)=0.84, P<0.001), with no overlap between the two states. These variables were also significantly correlated (r(2)=0.44, P<0.001) for entire torpor bouts. Moreover, estimates of from fH did not differ significantly from measured values during the different physiological states. Our study is the first to investigate the accuracy of fH as a predictor of during torpor and indicates the reliability of this method as a potential measure of energy expenditure in the field. Nevertheless, fH should only be used to predict within the range of activities for which robust correlations have been established.
