Measuring Light Pollution with Fisheye Lens Imagery from A Moving Boat, A Proof of Concept [PDF]

open access: yes, 2017
Near all-sky imaging photometry was performed from a boat on the Gulf of Aqaba to measure the night sky brightness in a coastal environment. The boat was not anchored, and therefore drifted and rocked.

Evaluating the summer night sky brightness at a research field site on Lake Stechlin in northeastern Germany [PDF]

open access: yes, 2016
We report on luminance measurements of the summer night sky at a field site on a freshwater lake in northeastern Germany (Lake Stechlin) to evaluate the amount of artificial skyglow from nearby and distant towns in the context of a planned study on light

Pollution lumineuse et trame verte et bleue : vers une trame noire en France ?

open access: yesTerritoire en Mouvement, 2017
Erosion of biodiversity is mainly caused by habitat loss and fragmentation. In this situation, ecological networks, which are composed by natural zones interconnected by corridors, are an operational answer preconized by scientists and developed by ...

Imaging and mapping the impact of clouds on skyglow with all-sky photometry [PDF]

open access: yes, 2017
Artificial skyglow is constantly growing on a global scale, with potential ecological consequences ranging up to affecting biodiversity. To understand these consequences, worldwide mapping of skyglow for all weather conditions is urgently required.

Contrasting effects of street light shapes and LED color temperatures on nocturnal insects and bats

open access: yesBasic and Applied Ecology, 2022
Street lights are important light sources that contribute to artificial light at night (ALAN). To date, ecological impacts of individual LED properties (color temperature, dimmability) have been studied, while interactions between light properties or ...

Chronodisruption of the acute inflammatory response by night lighting in rats

open access: yesScientific Reports, 2023
Daily oscillations are present in many aspects of the immune system, including responsiveness to infections, allowing temporal alignment of defence mechanisms with the external environment.

Effects of Low-Level Artificial Light at Night on Kentucky Bluegrass and Introduced Herbivore [PDF]

open access: yes, 2020
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

Rhythms of Locomotion Expressed by Limulus polyphemus, the American Horseshoe Crab: II. Relationship to Circadian Rhythms of Visual Sensitivity [PDF]

open access: yes, 2008
In the laboratory, horseshoe crabs express a circadian rhythm of visual sensitivity as well as daily and circatidal rhythms of locomotion. The major goal of this investigation was to determine whether the circadian clock underlying changes in visual ...

Artificial light at night decreases phyllosphere microbial diversity and functionality in grassland plants

open access: yesGlobal Ecology and Conservation
With the rapid expansion of artificial light in the global nocturnal environment, the ecological impacts of artificial light at night (ALAN) on plant communities have garnered increasing research interest. However, the role of phyllosphere microorganisms
