The present review draws together wide-ranging studies performed over the last decades
that catalogue the effects of artificial-light-at-night (ALAN) upon living species and their …

The ecological impacts of nighttime light pollution have been a longstanding source of
concern, accentuated by realized and projected growth in electrical lighting. As human …

Natural light cycles are being eroded over large areas of the globe by the direct emissions
and sky brightening that result from sources of artificial night-time light. This is predicted to …

The use of artificial lighting to illuminate the night has provided substantial benefits to
humankind. It has also disrupted natural daily, seasonal, and lunar light cycles as …

Many animals regulate their activity over a 24-h sleep–wake cycle, concentrating their peak
periods of activity to coincide with the hours of daylight, darkness, or twilight, or using …

Alternation between day and night is a predictable environmental fluctuation that organisms
use to time their activities. Since the invention of artificial lighting, this predictability has been …

Most processes within organisms, and most interactions between organisms and their
environment, have distinct time profiles. The temporal coordination of such processes is …

Most studies in chronobiology focus on solar cycles (daily and annual). Moonlight and the
lunar cycle received considerably less attention by chronobiologists. An exception are …

Light pollution is a worldwide problem that has a range of adverse effects on human health
and natural ecosystems. Using data from the New World Atlas of Artificial Night Sky …

Urban land and seascapes are increasingly exposed to artificial lighting at night (ALAN),
which is a significant source of light pollution. A broad range of ecological effects are …
