Behavioral responses of bioluminescent fireflies to artificial light at night

open access: yesFrontiers in Ecology and Evolution, 2022
Bioluminescent insects have been the subject of scientific interest and popular wonder for millennia. But in the 21st century, the fireflies, click beetles, and cave glow-worms that brighten our nights are threatened by an unprecedented competitor ...

Urban-like night illumination reduces melatonin release in European blackbirds (Turdus merula): implications of city life for biological time-keeping of songbirds [PDF]

open access: yes, 2013
<p>Introduction: Artificial light-at-night is known to affect a broad array of behaviours and physiological processes. In urbanized bird species, light-at-night advances important biological rhythms such as daily cycles of activity/rest and timing

First Estimation of Global Trends in Nocturnal Power Emissions Reveals Acceleration of Light Pollution

open access: yesRemote Sensing, 2021
The global spread of artificial light is eroding the natural night-time environment. The estimation of the pattern and rate of growth of light pollution on multi-decadal scales has nonetheless proven challenging.

Night Shift Work, Light at Night, and Risk of Breast Cancer [PDF]

open access: yesJNCI Journal of the National Cancer Institute, 2001
Exposure to light at night may increase the risk of breast cancer by suppressing the normal nocturnal production of melatonin by the pineal gland, which, in turn, could increase the release of estrogen by the ovaries. This study investigated whether such exposure is associated with an increased risk of breast cancer in women.Case patients (n = 813 ...

Snowglow—The Amplification of Skyglow by Snow and Clouds Can Exceed Full Moon Illuminance in Suburban Areas

open access: yesJournal of Imaging, 2019
Artificial skyglow, the fraction of artificial light at night that is emitted upwards from Earth and subsequently scattered back within the atmosphere, depends on atmospheric conditions but also on the ground albedo.

Impact of Light at Night Is Phase Dependent: A Study on Migratory Redheaded Bunting (Emberiza bruniceps)

open access: yesFrontiers in Ecology and Evolution, 2021
Artificial light at night (LAN) alters the physiology and behavior of an organism; however, very little is known about phase-dependent effects of LAN, particularly, in night migratory songbirds.

Long-term effects of chronic light pollution on seasonal functions of European blackbirds (turdus merula) [PDF]

open access: yes, 2013
Light pollution is known to affect important biological functions of wild animals, including daily and annual cycles. However, knowledge about long-term effects of chronic exposure to artificial light at night is still very limited.

Variation of Individual Location Radiance in VIIRS DNB Monthly Composite Images

open access: yesRemote Sensing, 2018
With the growing size and use of night light time series from the Visible Infrared Imaging Radiometer Suite Day/Night Band (DNB), it is important to understand the stability of the dataset. All satellites observe differences in pixel values during repeat

Streetlights Disrupt Night-Time Sleep in Urban Black Swans

open access: yesFrontiers in Ecology and Evolution, 2020
Artificial light at night could have widespread and detrimental impacts on sleep. To reduce disruptive effects of artificial light on sleep in humans, most smartphones and computers now have software that reduces blue light emissions at night.

Daylight operation of a free space, entanglement-based quantum key distribution system [PDF]

open access: yes, 2008
Many quantum key distribution (QKD) implementations using a free space transmission path are restricted to operation at night time in order to distinguish the signal photons used for a secure key establishment from background light.
