As a historian (of #night #ArtificialLight #ALAN #lightpollution), this is a fascinating study for so many reasons. And conveniently it is now in the conclusion of my Memphis talk for next week.

Daylight saving and circadian rhythms and killing wildlife on the roads
Crashing into the 'zone of wildlife'“[With] daylight saving, we start shifting our cars and our daily routine more into the zone of animals, their sunset, sunrise period … suddenly there are cars when all the dusk choruses are happening."
"Species that would be of obvious concern would be kangaroos and wallabies, that are often quite active both in the morning and in the afternoon around dusk, so any increased traffic around the time when they’re most active can create potential issues with road accidents,” Deakin University wildlife ecology and conservation professor Euan Ritchie says."
"Cars – with their lights and noise, and the danger they pose – can affect insects, birds and wildlife." >>

#Berlin not only boasts numerous lakes but also #waterways, both artificial and natural, all of which are sites of considerable #aquatic #biodiversity. My photos show the #BerlinSpandau #ShipCanal near the #Westhafen (a #harbor). C. C. Voigt et al. (2019) demonstrated the importance these waterways for terrestrial animals as well, namely e.g. #bats, which use #waterbodies and vegetated areas to bypass #artificiallight routes

Concern as #LightPollution encourages #birds to sing for longer, study finds
22 August 2025
"Birds around the world are singing for nearly an hour longer each day due to light pollution, a new study has shown.
"The research, to be published in the journal Science, used millions of recordings of #birdsong, including from #NewZealand's #NorthIsland.
"President of Birds New Zealand Dr Natalie Forsdick told RNZ more light meant more time for singing, building nests and feeding.
"But she said those things consumed energy and it could be reducing their overall health.
" 'It's just like with humans, if you go to bed a little bit too late, you wake up the next day feeling a little bit the worse for wear. I imagine that birds could feel that same way too, and we certainly see that it disrupts their natural cycles.'
"She said previous studies in New Zealand had shown a range of outcomes, from no effect to increased night-time predation by black-backed gulls on threatened species like banded dotterels.
"But one of the biggest concerns about light pollution in New Zealand was its effect on seabirds.
"Among juveniles, urban light pollution may be mistaken for moonlight, attracting and disorientating species like Cook's #petrel or Hutton's #shearwaters.
"This could cause birds to crash land or collide with buildings, and they may become injured or grounded in cities.
"She said people could help by turning off outside lights when they were not needed, and asking their local councils to consider more directional or dimmer lighting in public places. [I would recommended warmer lighting as well. Too much blue is unnatural!]
"Associate Professor Kristal Cain from the School of Biological Sciences at the University of Auckland said more research was needed to find out how light pollution affected survival and reproduction.
"This paper used bird song data collected by thousands of volunteers globally, and measured when birds started singing in the morning and when they stopped for the night.
"It found that in brighter areas birds started singing early and continued later into the night than in dark areas.
" 'Most of the bird song was collected in #NorthAmerica and #Europe,' Cain said. 'We still need to do similar work in the rest of the world to see how widespread these patterns really are. The manu of #Aotearoa are quite unique in many ways."
" 'Importantly, all this #ArtificialLight is not good for us either.'
"People could do things like closing curtains and planting trees in urban areas to contain some of the light."

Seeing fewer #fireflies this year? Here’s why, and how you can help.
Fireflies are vulnerable to #ClimateChange and habitat loss. Some simple landscaping tricks and turning off porch lights can make a big difference.
This coverage is made possible through a partnership between #Grist and #BPR, a #PublicRadio station serving western #NorthCarolina.
Katie Myers Regional Reporter, #Appalachia, July 11, 2025
Excerpt: "Basham and Jacobs have a few other tips for helping fireflies thrive. You don’t need to be a scientist to help protect fireflies. In fact, the biggest difference comes from how we care for our own #backyards. Here are a few things Basham and Jacobs recommend:
- Turn off your #PorchLights. Fireflies are incredibly sensitive to #ArtificialLight, and it can confuse them.
- Ditch the manicured lawn and embrace #NativePlants. In addition to being easier to care for, they suit the local environment and conserve water.
- Leave some leaves behind when you rake in the fall. They’re a great place for fireflies to find food, stay cool, and lay eggs.
- Plant shrubs, tufting grasses, and other, large plants. These can shelter fireflies during rainstorms and other severe weather.
- If you spot fireflies, jot down when and where you saw them and add your observations to citizen science databases like iNaturalist, Firefly Watch, or Firefly Atlas to help scientists collect data."Even among those who study fireflies, the thrill of spotting them remains magical. Lower has made many excursions to the southern #AppalachianMountains to find the famous, ethereal 'blue ghosts.' Rather than flicker, the insects emit a continuous bluish-green glow. 'You walk into the pitch black woods and at first you can’t really see anything right because your eyes are getting used to the darkness,' Lower said. 'But eventually you start to see all these dim glows.' "

#LightPollution May Harm Our #Ocean’s Water-Filtering ‘#Ecosystem Engineers’
ByAllison Eck
Friday, May 1, 2015"#SeaSquirts are the ocean’s ecosystem engineers, siphoning #plankton from the water and keeping #CoastalEcosystems healthy. They’ve done their job for millennia relatively unscathed, in part because they have no predators. But now, they have one: #ManmadeLight [#ArtificialLight].
"A new study published in Biology Letters suggests that the artificial light from #cities might prevent the #larvae of some marine species—like sea squirts, #barnacles, and #corals—from finding appropriate habitats to settle in. Without landing on the right substrate, sea squirt larvae have little chance of surviving.
"Thomas Davies, an ecologist at the University of Exeter in the #UK, wanted to see which species are the most affected. He studied the #MenaiStrait, which separates the mainland of northwest #Wales from the island of #Anglesey. This area is largely unaffected by light pollution, which led Davies and his team of experts to suspect that an experiment conducted there would provide a good measure of the effect light pollution has on populations.
"By their measurements, the '#SkyGlow,' or ambient manmade light reflected onto the water by the atmosphere, is at a minimum—it barely amounts to the light emanated from the moon at night.
"To investigate the effect of artificial light on the area, they placed 36 plastic panels into the water and waited to see which organisms would settle on the panels. Some panels were exposed to light from cool, white #LEDs that emitted about the same amount of light produced by #streetlights, while the control panels mimicked just the small amount of ambient light scattered in the sky.
"The team retrieved the panels after 12 weeks to see how much of the panels’ surface area had been colonized. Sea squirts and sea bristles, both filter feeders, had lower colonization rates on the artificial light panels than the controls. On the flip side, #foulers like barnacles ended up clinging to the artificial light panels, which could explain why they so often attached to boat hulls and jetties. Barnacles in particular cost the global economy millions of dollars in reduced fuel economy and cleanup costs.
"Here’s Katie Wheeling, writing for Science: 'Overall, the study found that the lights either encouraged or discouraged settlement in 39% of the taxa, or groups of species, living on the panels by the end of the experiment period. Artificial light may be negatively impacting marine ecosystems by driving away certain invertebrate species, like filter feeders, and attracting others, the team reports.
"'More work needs to be done to understand how brightness, cycle of exposure, and wavelength of light affects individual species. In the future, experts may be able to configure exact spectra that work well with ocean species but also fill our own needs. For now, the team’s complex results indicate that we may need to pay more attention to how manmade light is damaging marine environments.'"

Happy #InternationalDayOfLight! The myriad ways that humans harness light is vital for powering our modern society. As an astrophysicist, I already had an appreciation for the deep understanding of light and how to measure it that underpins the entirety of the subject. My recent research on #artificiallight and its #ecological impacts have given me a further respect for lights role mediating our ecosystems.
Find out a bit more about the International Day of Light:
https://www.lightday.org/about -
"A second piece of legislation, the Dark Skies Protection Act, S.7663/A5632 would significantly reduce #LightPollution in #NewYork by requiring most non-essential outdoor #lighting be covered by an external shield, be motion-activated, or be turned off between 11 PM and 5 AM. ... The Dark Skies Act will help create a safer environment for #birds by reducing the #ArtificialLight in our night skies."
