抄録: The factual ecological information on thermoregulatory behavior of pika (whistle rabbit) is almost scanty, therefore, the present study was designed to determine whether the pika is a diurnal or nocturnal animal, from the analytical data of locomotor activity in the labolatory condition. Under the light (8:00-20:00)-dark (20:00-8:00) photoperiod, four cases of locomotion activity measured by using an air-vibration detector which was modified of an earphone-receiver attached to the animal cage confirmed that locomotion behavior of the pika trends foward more active in early morning as well as in evening untill midnight. And furthermore in the visual observation on 27 pikas (experiment period: n=134), the peak time of the resting phase of the locomotor curve was at 17:00 in the light phase, and the moving phase of the locomotion curve indicated a complete mirror image of recording to the resting one. This suggests that the pika might be a nocturnal animal. Therefore from these findings, behavioral thermal adaptation in relation to evolutional changes of temperature regulation of the pika was discussed in this study.
