Seasonal activity and behavioural responses to artificial light at night in migratory and non‐migratory sparrows

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 ...

Design and implementation of an illumination system to mimic skyglow at ecosystem level in a large-scale lake enclosure facility

, 2023
Light pollution is an environmental stressor of global extent that is growing exponentially in area and intensity. Artificial skyglow, a form of light pollution with large range, is hypothesized to have environmental impact at ecosystem level.

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‐

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 ...

Worldwide variations in artificial skyglow

, 2020
Despite constituting a widespread and significant environmental change, understanding of artificial nighttime skyglow is extremely limited. Until now, published monitoring studies have been local or regional in scope, and typically of short duration.

Intensity and colour of artificial light at night affect insect attraction in a taxon‐dependent manner

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.

Reddening the nighttime environment: Use of PC‐amber LED lighting

Ecological Solutions and Evidence, Volume 6, Issue 4, October–December 2025.
The use of Phosphor‐converted amber (PC‐amber) LED lamps has been widely championed as a means of reducing the environmental impacts of the use of artificial light at night. Here we argue that evidence for the efficacy of PC‐amber LEDs in such reductions is presently limited and that these lamps should not be seen as a panacea for the environmental ...

Dreamy Dwellings: How the Sleep Environment Affects Sleep Health in Adults—A Narrative Review

Lifestyle Medicine, Volume 6, Issue 4, October 2025.
ABSTRACT Sufficient high‐quality, well‐timed sleep is essential to health and physical, cognitive and emotional functions. Historically, environmental factors such as threats from other beings have likely constrained sleep. Newer sources of sleep disruption include modern work schedules, climate change, light pollution and noise pollution.
