aSR-“Strongly rhythmic”. Proportion of insects (%) whose power levels were above 500. WR-“Weakly rhythmic”. Proportion of insects (%) whose power levels were below 500. See results for details
-
bFree-running period length (in hours ± SEM) was calculated in three different time windows: (i) considering all 23 days under DD (τ23); (ii) the first ten days (τ1–10); and (iii) the last thirteen days (τ11–23). See Methods for details
-
cThe power of the rhythm was defined as the amplitude from the peak to the cutoff line (α = 0.05) in the χ
2 periodogram (Liu et al. [32]). See methods for details. The power level was calculated in three different time windows. Power 23: considering all 23 days under DD. Power 1–10: the first ten days. Power 11–23: the last thirteen days
