Twilight dominates over moonlight in adjusting Drosophila's activity pattern.

Journal of biological rhythms - 1 Apr 2015

Schlichting Matthias, Grebler Rudi, Menegazzi Pamela, Helfrich-Förster Charlotte

Abstract excerpt

Light is the most important zeitgeber for the synchronization of the Drosophila melanogaster circadian clock. In nature, there is twilight, and the nights are rarely completely dark, a fact that is usually disregarded in lab experiments. Recent studies showed contrary effects of simulated twilight and moonlight on fly locomotor activity, with twilight shifting morning and evening activity into the day and...
