马菊头蝠Rhinolophus ferrum equinum和马菊头蝠R.来自切达洞穴的河马被饲养在接近其原生栖息地的条件下。直肠，翼下，或背部温度。这些和一个[女性] Nyctalus arctula，采取了热电偶，表明这些蝙蝠没有机制，为维护一个恒定的温度。每当他们睡觉时，他们都假设温度。他们的环境，当第一次醒来时，他们表现出缓慢的，爬行动物的行为类型，不能飞。但是，它们很快就升温到一个温度。30-40[degree] C.，的最大随着动物的活动和气温的变化而变化。活动的每一个变化都伴随着温度的变化，当运动停止时，它们会冷却到空气温度某些较大的果蝠（Pteropus geddiei、P. tagteus和P. eo-tinus）在圈养中从未完全入睡，但通过持续的活动和颤抖保持了相当高的温度。（33-37.5[degree] C.）。在冬季采取的马蹄蝙蝠的呼吸商被发现通常在0.7和0.8之间，观察到的最低商为0.59。结论是，这些动物的所谓冬眠与它们的日常夏季睡眠没有本质上的区别，这一点可以通过它们在冬季的任何时候醒来并进食的事实得到证实。
Rhinolophus ferrum equinum and R. hipposideros from the Cheddar Caves were kept under conditions approaching those of their native habitat. Rectal, under-wing, or dorsal temps. of these and of a [female] Nyctalus noctula, taken by thermocouples, indicated that these bats have no mechanism for the maintenance of a constant temp. Whenever they go to sleep they assume the temp. of their surroundings, and when first waked they show a slow, reptilian type of behavior and cannot fly. However, they rapidly warm up to a temp. of 30-40[degree] C., the max. varying with the activity of the animal and with the air temp. Every variation in activity is accompanied by a change of temp., and when movement stops they cool off to air temp. Certain larger fruit bats (Pteropus geddiei, P. giganteus, and P. eo-tinus), never became fully asleep in captivity, but by continued activity and shivering maintained a fairly high though variable temp. (33-37.5[degree] C.). The respiratory quotient of horseshoe bats taken during the winter was found to be usually between 0.7 and 0.8, the lowest quotient observed being 0.59. It is concluded that the so-called hibernation of these animals does not differ essentially from their daily summer sleep, and this is confirmed by the fact that they may wake and take food at any time during the winter.
