Abstract

We have studied the dynamics of the singing of garden bunting (Emberiza hortulana) and the dispersal of a flock of starlings (Sturnus vulgaris) for the night rest. The results were compared with the body temperature fluctuations measured in parallel in a group of laboratory mice. The validity of such comparisons was determined by the presence of a stable correlation between the indicators of minutely changes in body temperature in mice and greenfinches (Chloris chloris). The increase in the frequency of chanting of garden buntings was observed simultaneously with the increase in body temperature in mice. Moreover, the exact moments of the flights into the birdhouse for the night in starlings coincided with the maximums in the dynamics of minutely changes in body temperature of mice. These facts suggest an external synchronizer of “spontaneous” fluctuations of the activity and associated changes in body temperature, which are probably determined by the tone of the sympathetic nervous system.

动物周期性的“自发”活动是由外部环境的准节奏因素决定的吗?

摘要

我们研究了花园彩旗 ( Emberiza hortulana )的歌唱动态和夜间休息的椋鸟 ( Sturnus vulgaris )的散播动态。结果与在一组实验室小鼠中平行测量的体温波动进行了比较。这种比较的有效性取决于小鼠和绿翅雀(Chloris chloris)体温微小变化指标之间的稳定相关性。)。在小鼠体温升高的同时,观察到花园彩旗吟唱频率的增加。此外,椋鸟夜间飞入鸟舍的确切时刻与小鼠体温微小变化的动力学最大值相吻合。这些事实表明活动的“自发”波动和相关体温变化的外部同步器,这可能是由交感神经系统的基调决定的。
