Abstract

Changes in elements in circadian rhythmicity have been observed during puberty in humans and other animals but has not yet been investigated in Mongolian gerbils, a laboratory rodent more diurnal than commonly used mice and rats. The present experiment investigated the effect of puberty on the circadian rhythmicity of daily motor activity as determined by activity on a running wheel. Neither of the two cohorts of gerbils experienced changes in the timing of the acrophase (the daily peak of activity) nor mean activity, but one cohort became significantly less diurnal following the completion of puberty. The findings here indicate that Mongolian gerbils experience a change in diurnality following the completion of puberty, without a shifting of the timing of the circadian rhythm of activity nor a change in the amount of daily motor activity.
