Spatial sensitivity of human circadian response: Melatonin suppression from on-axis and off-axis light exposures

Neurobiology of Sleep and Circadian Rhythms, 2021
A better understanding of the spatial sensitivity of the human circadian system to photic stimulation can provide practical solutions for optimized circadian light exposures. Two psychophysical experiments, involving 25 adult participants in Experiment 1

Do Wild Great Tits Avoid Exposure to Light at Night? [PDF]

, 2016
Studies of wild populations have provided important insights into the effects of artificial light at night on organisms, populations and ecosystems. However, in most studies the exact amount of light at night individuals are exposed to remains unknown ...

Artificial light impacts the mate success of female fireflies

Royal Society Open Science, 2022
Anthropogenic light pollution is a novel environmental disruption that affects the movement, foraging and mating behaviour of nocturnal animals. Most of these effects are sublethal, and their net impact on reproductive fitness and population persistence ...

Dark matters: effects of light at night on metabolism [PDF]

, 2018
Life on earth has evolved during the past several billion years under relatively bright days and dark night conditions. The wide-spread adoption of electric lights during the past century exposed animals, both human and non-human, to significant light at

Evidence That Reduced Air and Road Traffic Decreased Artificial Night-Time Skyglow during COVID-19 Lockdown in Berlin, Germany

Remote Sensing, 2020
Artificial skyglow, the brightening of the night sky by artificial light at night that is scattered back to Earth within the atmosphere, is detrimental to astronomical observations and has an impact on ecosystems as a form of light pollution.
