  Abstract Life on earth is entrained to a 24 h solar cycle that synchronizes circadian rhythms in physiology and behavior; light is the most potent entraining cue. In mammals, light is detected by (1) rods and cones, which mediate visual function, and (2) intrinsically photosensitive retinal ganglion cells (ipRGCs), which primarily project to the suprachiasmatic nucleus (SCN) in the hypothalamus to regulate circadian rhythms. Recent evidence, however, demonstrates that ipRGCs also project to limbic brain regions, suggesting that, through this pathway, light may have a role in cognition and mood. Therefore, it follows that unnatural exposure to light may have negative consequences for mood or behavior. Modern environmental lighting conditions have led to excessive exposure to light at night (LAN), and particularly to blue wavelength lights. We hypothesized that nocturnal light exposure (i.e., dim LAN) would induce depressive responses and alter neuronal structure in hamsters (Phodopus sungorus). If this effect is mediated by ipRGCs, which have reduced sensitivity to red wavelength light, then we predicted that red LAN would have limited effects on brain and behavior compared with shorter wavelengths. Additionally, red LAN would not induce c-Fos activation in the SCN. Our results demonstrate that exposure to LAN influences behavior and neuronal plasticity and that this effect is likely mediated by ipRGCs. Modern sources of LAN that contain blue wavelengths may be particularly disruptive to the circadian system, potentially contributing to altered mood regulation.

  Title Combined effects of nocturnal exposure to artificial light and habitat complexity on fish foraging Type Journal Article
  Year 2019 Publication Science of The Total Environment Abbreviated Journal Science of The Total Environment  
  Volume 684 Issue Pages 14-22  
  Keywords (up) Animal; fishes; Perca fluviatilis; Gammarus fossarum; gammarids; aquatic ecosystems  
  Abstract Due to the widespread use of artificial light, freshwater ecosystems in urban areas at night are often subjected to light of intensities exceeding that of the moonlight. Nocturnal dim light could modify fish behaviour and benefit visual predators because of enhanced foraging success compared to dark nights. However, effects of nocturnal light could be mitigated by the presence of structured habitats providing refuges for prey. We tested in laboratory experiments whether nocturnal light of low intensity (2 lx) increases foraging efficiency of the Eurasian perch (Perca fluviatilis) on invertebrate prey (Gammarus fossarum). The tests were conducted at dusk and night under two light regimes: natural cycle with dark nights and disturbed cycle with artificially illuminated nights, in habitats differing in structural complexity: sand and woody debris. We found that nocturnal illumination significantly enhanced the consumption of gammarids by fish compared to dark nights. In addition, the perch was as effective predator in illuminated nights (2 lx) as at dusk (10 lx). Woody debris provided an effective refuge only in combination with undisturbed darkness, but not in illuminated nights. Our results suggest that nocturnal illumination in aquatic ecosystems may contribute to significant reductions in invertebrate population sizes through fish predation. The loss of darkness reduces the possibility of using shelters by invertebrates and hence the effects of elevated light levels at night could not be mitigated by an increased habitat complexity.

  Title Bats and lighting — six years on Type Journal Article
  Year 2012 Publication The London Naturalist Abbreviated Journal  
  Volume 91 Issue Pages 69-88  
  Keywords (up) Animals  
  Abstract Since my ‘Bats and lighting’ review (Fure 2006), there has been interesting comment

from a number of sources: bat workers, entomologists and those from ophthalmic fields;

lighting professionals from the UK and Europe; and natural light campaigners (CPRE

and the Campaign for Dark Skies, CfDS). There has also been an increase in studies,

reviews, publications and guidance.Topics range from bat ecology, bat physiology, bats v.

illumination and insects v. illumination, and as prey species, rendering the initial review

out of date. All beg for a swift and positive intervention to change the way that we light

the environment
