Historical Exposure to Artificial Light at Night Shapes <i>Daphnia</i> Responses: An Experiment Across an Urban-Rural Gradient. [PDF]

open access: yesEcol Evol
ABSTRACT Artificial light at night (ALAN) is an increasingly pervasive environmental stressor, yet its long‐term impacts on organisms are poorly understood. We used Daphnia pulicaria to investigate how historical exposure to ALAN influences life‐history and morphological responses when exposed to ALAN under laboratory conditions. The experiment spanned

The effect of light pollution on the leafing phenophase: the key study of Voglajna valley and the upper Posotelje

open access: yesRevija za Geografijo, 2022
Light pollution is one of the forms of pollution triggered by man's desire to lengthen the day. Its negative effects on the environment were discovered decades ago.

Calibrating Nighttime Satellite Imagery with Red Photometer Networks

open access: yesRemote Sensing, 2023
The data retrieved from satellite imagery and ground-based photometers are the two main sources of information on light pollution and are thus the two main tools for tackling the problem of artificial light pollution at night (ALAN). While satellite data

Effects of Low-Level Artificial Light at Night on Kentucky Bluegrass and an Introduced Herbivore

open access: yesFrontiers in Ecology and Evolution, 2021
Increasing evidence suggests that artificial light at night (ALAN) can negatively impact organisms. However, most studies examine the impacts of ALAN on a single species or under high levels of artificial light that are infrequent or unrealistic in urban

A standard format for measurements of skyglow [PDF]

open access: yesProceedings of the International Astronomical Union, 2012
AbstractA standard format for recording skyglow measurements is needed to allow for effective data exchange. A proposal for such a format was discussed at the IAU Symposium.

A linear systems approach to protect the night sky: implications for current and future regulations [PDF]

open access: yesRoyal Society Open Science, 2020
The persistent increase of artificial light emissions is causing a progressive brightening of the night sky in most regions of the world. This process is a threat for the long-term sustainability of the scientific and educational activity of ground-based

Recovering the city street lighting fraction from skyglow measurements in a large-scale municipal dimming experiment [PDF]

open access: yes, 2020
Anthropogenic skyglow dominates views of the natural night sky in most urban settings, and the associated emission of artificial light at night (ALAN) into the environment of cities involves a number of known and suspected negative externalities.

Casting a light on the shoreline: The influence of light pollution on intertidal settings

open access: yesFrontiers in Ecology and Evolution, 2022
Light pollution is becoming prevalent among other coastal stressors, particularly along intertidal habitats, arguably the most exposed to anthropogenic light sources.
