体温测量2澳大利亚蝙蝠，长翼蝠和Pteropus poliocephalus，在活动和环境温度。长翼蝠（49个值）显示，在捕获后8小时内，所有活动水平的平均[±]标准差为39.1 [±]1.0[degree] C。长时间飞行后的平均温度为41.1[degree] C，休息期间为37.2[degree] C。在5[degree] C下1-3天后观察到较低的值，与其他Microchiroptera一样。狐蝠（23个值）在室温下的平均温度为36.5 [±] 0.77[度] C。环境温度达到10[degree] C并没有降低体温。耗氧量的测量结果显示，冷（2.5 x BMR）和热导率显著增加，0.068 ccO 2g-1hr。1[degree]C-1，相当于这种体型的温带哺乳动物。BMR，0.84 ccO2 g-1 hr.- 1，也遵循哺乳动物的一般关系。
Body temperatures were measured in 2 Australian bats, Miniopterus blepotis and Pteropus poliocephalus, in relation to activity and ambient temperature. Miniopterus (49 values) showed a mean [plus or minus] standard deviation of 39.1 [plus or minus]1.0[degree] C for all activity levels within 8 hours of capture. The mean after prolonged flight was 41.1[degree] C and during rest was 37.2[degree] C. Lower values were observed following 1-3 days at 5[degree] C, as in other Microchiroptera. Pteropus (23 values) showed a mean of 36.5 [plus or minus] 0.77[degree] C at room temperature. Ambient temperatures to 10[degree] C did not reduce the body temperature. Measurements of oxygen consumption showed a marked increase in the cold (2.5 x BMR) and a thermal conductance, 0.068 ccO2g -1hr.-1[degree]C-1 comparable to a temperate mammal of this size. The BMR, 0.84 ccO2 g-1hr.-1, also followed the general relation for mammals.
