Altered circadian rhythm, sleep, and rhodopsin 7-dependent shade preference during diapause in Drosophila melanogaster

Geoffrey T. Meyerhof, Sreesankar Easwaran, Angela E. Bontempo…·Denise J. Montell

This study shows that cool temperatures induce deep sleep and alter circadian rhythms in Drosophila melanogaster during diapause, with sleep overriding light-aversion behaviors.
