Photoentrainment (chronobiology)

In chronobiology, photoentrainment refers to the process by which an organism's biological clock, or circadian rhythm, synchronizes to daily cycles of light and dark in the environment. The mechanisms of photoentrainment differ from organism to organism.[1] Photoentrainment plays a major role in maintaining proper timing of physiological processes and coordinating behavior within the natural environment.[2][3] Studying organisms’ different photoentrainment mechanisms sheds light on how organisms may adapt to anthropogenic changes to the environment.[4][5]
