The recording over several days of the respiratory gases of groups of different laboratory vertebrates (mice, rats, quails), placed in a chamber with controlled ventilation, and in standardized environmental conditions of temperature, humidity, light, noise and feeding, shows ultradian (tau less than 24 hr) and circadian (tau congruent to 24 hr) rhythms. A simple variance analysis method shows periodic carbon dioxide changes, due to different environmental stimuli. Societal, light, acoustical, carbon monoxide and starvation challenges are given as examples. This technique enables us quickly to collect, on a great number of animals, data which correspond to societal behavior changes peculiar to the considered species.
将不同组别的实验脊椎动物（小鼠、大鼠、鹌鹑）置于通风可控的实验舱内，并处于温度、湿度、光照、噪音和喂食等标准化环境条件下，连续数天记录其呼吸气体，结果显示出超日节律（周期小于24小时）和昼夜节律（周期约为24小时）。一种简单的方差分析方法表明，由于不同的环境刺激，二氧化碳会发生周期性变化。文中给出了社会、光照、声学、一氧化碳和饥饿等刺激因素作为示例。这项技术使我们能够快速收集大量动物的数据，这些数据与所研究物种特有的社会行为变化相对应。
