Periodograms for two kinds of simulated crepuscular activity sampled every hour. (a) For the “one rest type” activity, the daily behavioral sequence was defined by SK = {m1, m3, m1, m3} and EK = {4, 8, 4, 8} (the expected temporal durations for each movement mode mik) interpreted as alternating between rest and taxis. (b) The “two rest types” activity was defined by SK = {m1, m3, m2, m3} and EK = {4, 4, 12, 4}, interpreted as the sequence rest, taxis, feed, taxis. The power spectrum in each figure panel represents the mean of 100 normalized periodograms. Horizontal dashed lines are drawn at the value of a theoretical white-noise spectrum.
