, 2014 Images of the Earth at night are an exceptional source of human geographical data, because artificial light highlights human activity in a way that daytime scenes do not.

Journal of Avian Biology, Volume 2026, Issue 1, January 2026.Urban and rural nocturnal environments are increasingly brighter due to artificial light at night (ALAN), causing wide‐ranging biological responses, from reproductive impairment to behavioural changes in diverse taxa. Songbirds may be particularly vulnerable, as their reproductive and migratory behaviours are under endogenous control and regulated by ...

Artificial light alters spatial and temporal habitat use by a crepuscular aerial insectivore
Ibis, Volume 168, Issue 1, Page 308-328, January 2026.Artificial light is increasing worldwide, and has biological effects from molecular to ecosystem levels, which may be particularly severe for crepuscular and nocturnal animals. We investigated how artificial light affected spatial and temporal patterns of habitat use by Common Nighthawks Chordeiles minor in the southern Grassland and northern Boreal ...

Artificial light at night alters earthworm communities and soil aggregation
Journal of Applied Ecology, Volume 62, Issue 12, Page 3408-3420, December 2025.Our results provide evidence that continuous night‐time street lighting can affect earthworm communities and earthworm‐driven soil aggregation. The nature of these effects differed across earthworm ecological categories and age classes and appeared to depend on illuminance, light spectrum and/or plant cover. This highlights that, rather than a one‐size‐

The Correlation Between Star Formation and 21cm Emission During the Reionization Epoch
, 2007 Reionization is thought to be dominated by low mass galaxies, while direct observations of resolved galaxies probe only the most massive, rarest objects.

Satellite Imagery Reveals Near‐Horizon Urban Light Emissions Impacting Ambient Environment
Journal of Geophysical Research: Atmospheres, Volume 130, Issue 22, 28 November 2025.Abstract A novel method has been developed to characterize ground‐based light sources from nighttime satellite imagery. The fraction of light directed toward low elevation angles is determined relative to the total emission into the upper hemisphere. This approach aims to identify locations that exhibit an increased amount of light emission at angles ...

Safe and Truly Ecofriendly LED Lighting
Energy Science &Engineering, Volume 13, Issue 11, Page 5068-5074, November 2025.ABSTRACT Truly ecofriendly and safe light‐emitting diode (LED) lighting in the built and urban environments requires the use of LED lights emitting significantly lower amount of blue light than conventional, first‐generation white LED lights. Thanks to substantial technology progress in the design and manufacturing of LEDs, this is now possible at the ...

Insect Conservation and Diversity, Volume 18, Issue 6, Page 1099-1108, November 2025.We measured the phototactic responses of insects to light at night using LED traps emitting light at four narrowband wavelengths of three intensity levels of relatively equal photon emission. Our data show an interaction between insect order and narrowband spectra, with marked differences in attraction between Lepidoptera and Diptera.

The nature, extent, and ecological implications of marine light pollution [PDF]
, 2018 This is the final version of the article. Available from Ecological Society of America via the DOI in this record.Despite centuries of use, artificial light at night has only recently been recognized as a cause for environmental concern.
