我们报告的周期反应曲线（τRC）的两个夜间Murid种从印度，Mus booduga和Mus platythrix。我们进一步讨论了在τ变化的情况下的相移估计方法，因为这种变化在相移估计中提出了严重的方法学问题。虽然τRC表明大部分相移与τ的微小变化有关，但所有相位的周期变化与相移呈显著正相关。我们的结论是，τ RC是一个现实，即使在夜间哺乳动物，虽然它们的振幅小于通常发现在白天哺乳动物，并需要一个更大的数据集，以区分噪音。
We report period response curves (τRC) for two nocturnal Murid species from India, Mus booduga and Mus platythrix. We further discuss the method of phase shift estimation in the presence of τ-changes, because such changes pose a serious methodological problem in the estimation of phase shifts. Although the τRC indicates that most of the phase shifts are associated with small changes in τ, the period changes across all the phases showed a significant positive correlation with the phase shifts. We conclude that τRCs are a reality even in nocturnal mammals, although their amplitude is less than what is usually found in diurnal mammals, and requires a larger data set to be distinguished from noise.
