The study monitored the long-term body temperature (BT) oscillations of C57BL/6 mice and outbred starlings (Sturnus vulgaris) to compare them with fluctuation in decay rate of radioactive natural K isotope. The spectrum analysis revealed simultaneous changes of the predominant periods in BT spectra of the animals and those in fluctuation in K decay rate. A positive correlation was established between BT dynamics and fluctuation in decay rate. The superposed epoch analysis revealed predominant coincidence of the moments of BT and fluctuation in K decay rate. The novel data indicate association between BT ultradian rhythms with quasirhythmic variations of fluctuation in K decay rate.
该研究监测了 C57BL/6 小鼠和野禽（Sturnus vulgaris）的长期体温（BT）波动，以比较它们与放射性天然 K 同位素衰变率波动的关系。频谱分析显示，动物 BT 谱中的主要周期变化与 K 衰变率波动同时发生。BT 动力学与衰变率波动之间存在正相关关系。叠加epoch 分析显示，BT 和 K 衰变率波动的主要时刻存在显著的一致性。这些新数据表明，BT 的超周期节律与 K 衰变率波动的准周期性变化之间存在关联。
