Artificial skyglow disrupts celestial migration at night [PDF]

Current Biology, 2020
Torres et al. demonstrate that artificial skyglow disrupts nightly migrations undertaken by the amphipod Talitrus saltator, which is normally guided by the sky position of the moon.

Skyglow increases cyanobacteria abundance and organic matter cycling in lakes

Water Research
Artificial light propagating towards the night sky can be scattered back to Earth and reach ecosystems tens of kilometres away from the original light source. This phenomenon is known as artificial skyglow. Its consequences on freshwaters are largely unknown.

Skyglow relieves a crepuscular bird from visual constraints on being active

Science of the Total Environment, 2023
Artificial light at night significantly alters the predictability of the natural light cycles that most animals use as an essential Zeitgeber for daily activity. Direct light has well-documented local impacts on activity patterns of diurnal and nocturnal organisms.

On the feasibility of using ceilometer backscatter profile as input data for skyglow simulation

Journal of Quantitative Spectroscopy and Radiative Transfer, 2020
Abstract Atmospheric conditions can significantly affect the sky brightness originating from artificial lights. Previous works studied the cloudiness, cloud base height, optical depth of cloud, aerosol optical depth and aerosol scale height as atmospheric parameters affecting night sky brightness. Instead of using these parameters as a simplification

Skyglow effects in UV and visible spectra: Radiative fluxes

Journal of Environmental Management, 2013
Several studies have tried to understand the mechanisms and effects of radiative transfer under different night-sky conditions. However, most of these studies are limited to the various effects of visible spectra. Nevertheless, the invisible parts of the electromagnetic spectrum can pose a more profound threat to nature. One visible threat is from what

Skyglow and especially direct streetlight pollution alter moth communities

Environmental Pollution
Light pollution caused by artificial light at night (ALAN) affects biodiversity worldwide and is still increasing. Species vary in their response to ALAN, but the impact on communities remains poorly understood. Effects of indirect light pollution by skyglow and direct streetlight pollution on communities have usually been addressed separately, and in ...

Can skyglow reduce nocturnal melatonin concentrations in Eurasian perch?

Environmental Pollution, 2020
Artificial light at night (ALAN) changes the natural rhythm of light and darkness and can impair the biorhythms of animals, for example the nocturnal melatonin production of vertebrates, which serves as a proxy for daily physiological rhythms. Freshwater fish are exposed to ALAN in large urban and suburban areas in the form of direct light or in the ...

Numerical research on the effects the skyglow could have in phytochromes and RQE photoreceptors of plants

Journal of Environmental Management, 2018
The increase of artificial light at night has a terrible impact on organisms with nightlife patterns such as a migration, nutrition, reproduction and collective interaction. Plants are not free from this issue as they have life cycle events occurring not only yearly but also daily.
