| Title | Waters under Artificial Lights: Does Light Pollution Matter for Aquatic Primary Producers? | Type | Journal Article | ||

| Abstract | Bright night lights have become a symbol of development and prosperity in the modern world. But have you ever wondered how artificial light at night (ALAN) may be affecting living beings in our cities, and how it may be affecting us? As artificial illumination is transforming nocturnal environments around the world, light pollution associated with its use is becoming a topic of increasing interest in the scientific and public communities. Light pollution disrupts natural light regimes in many regions of the world, raising concerns about ecological and health impacts of this novel anthropogenic pressure. Most obviously, ALAN can influence night‐active animals in urban and suburban areas, and most research in this growing field focuses on terrestrial organisms such as bats, birds, and insects. Effects on aquatic ecosystems are much less known. In particular, aquatic primary producers, such as microalgae, cyanobacteria, and plants, have rarely been studied despite their critical positioning in the base of aquatic food webs and the fundamental role that light plays in their ecology. For primary producers, light is a key source of both energy and environmental information; it influences their growth, production, and community structure. ALAN has therefore a large potential to influence their communities and induce bottom‐up changes to aquatic ecosystems and ecosystem functions. | ||||

| Title | Illuminating the Enlightenment: Public Lighting Practices in the Siècle Des Lumières* | Type | Journal Article | ||

| Abstract | This article explores the relationship between the Enlightenment as a cultural and intellectual phenomenon and actual illumination in the long 18th century. Focused on street lighting in Paris, it nonetheless seeks to situate the French case in the broader context of developments in public lighting in the French provinces, Europe, and the Atlantic World. In the concerted effort to illuminate dark streets, the Enlightenment was operationalized in ways that bore fundamentally on commerce, sociability, and perceptions of progress, enlightened government, and enlightened space. At the same time, the attempt to illuminate formerly dark spaces generated reactions. A ‘dialectic of illumination’ was the counterpart to the dialectic of Enlightenment, fostering resistance to the new regime of light and its efforts to impose, through human ingenuity and instrumental reason, greater security and social control. | ||||

| Title | Blue Light Hazard: are exposure limit values protective enough for newborn infants? | Type | Journal Article | ||
| Year | 2018 | Publication | Radioprotection | Abbreviated Journal |
|
| Volume | 53 | Issue | 3 | Pages | 219-224 |
| Keywords | Human Health | ||||
| Abstract | Blue Light Hazard is an emerging concern for health of population. Nevertheless, acute exposure to blue rays from artificial light is well taken into account by normative requirements applicable to lamps engineering and risk for general population is low. There is also no evidence for a chronic effect of artificial lighting on retina for general population at radiance below exposure limit values. That said, children in the very first years of life constitute a specific population to consider. On one side, eye anatomy of very young infants is different from elder young people or adults. On the other side, infants can be in close contact with some luminous toys or night lights. This paper presents a first approach for taking into account the specific anatomy of newborn infants’ eyes in blue light hazard evaluation. Results show that differences of crystalline lens transparency, focal length and pupil diameter could induce a significantly higher retinal exposure than for adult. | ||||

| Title | Habitual Light Exposure Relative to Circadian Timing in Delayed Sleep-Wake Phase Disorder | Type | Journal Article | ||
| Year | 2018 | Publication | Sleep | Abbreviated Journal |
|
| Volume | in press | Issue | Pages | ||
| Keywords | Human Health | ||||
| Abstract | Study Objectives To compare melatonin timing, a well validated marker for endogenous circadian phase, and habitual light exposure patterns in adults with delayed sleep-wake phase disorder (DSWPD) and intermediate chronotype controls. Methods 12 individuals with DSWPD (5 females, mean age 31.1) and 12 age matched controls (6 females, mean age 33.6) underwent a minimum of seven days of light and activity monitoring followed by an inpatient hospital stay, where blood was taken to assess melatonin timing (calculated as dim light melatonin onset – DLMO). Habitual light exposure patterns were then compared to a human phase response curve (PRC) to light. Results Relative to clock time, individuals with DSWPD had a later light exposure pattern compared to controls, but their light exposure pattern was earlier relative to DLMO. According to the human phase response curve (PRC) to light, individuals with DSWPD had less daily advancing light exposure compared to controls. The primary difference was seen in the late portion of the advancing window, in which individuals with DSWPD were exposed to fewer pulses of light of equivalent duration and intensity compared to controls. Conclusions Diminished advancing light exposure may play a role in the development and perpetuation of delayed sleep-wake timing in individuals with DSWPD. Enhancing light exposure during the later portion of the advancing window represents an innovative and complementary strategy that has the potential to improve the effectiveness of bright light therapy in DSWPD. |

| Abstract | The prevalence of artificial light at night (ALAN) is increasing rapidly around the world. The potential physiological costs of this night lighting are often evident in life history shifts. We investigated the effects of chronic night-time exposure to ecologically relevant levels of LED lighting on the life history traits of the nocturnal Australian garden orb-web spider (Eriophora biapicata). We reared spiders under a 12-h day and either a 12-h natural darkness (∼0 lux) or a 12-h dim light (∼20 lux) night and assessed juvenile development, growth and mortality, and adult reproductive success and survival. We found that exposure to ALAN accelerated juvenile development, resulting in spiders progressing through fewer moults, and maturing earlier and at a smaller size. There was a significant increase in daily juvenile mortality for spiders reared under 20 lux, but the earlier maturation resulted in a comparable number of 0 lux and 20 lux spiders reaching maturity. Exposure to ALAN also considerably reduced the number of eggs produced by females, and this was largely associated with ALAN-induced reductions in body size. Despite previous observations of increased fitness for some orb-web spiders in urban areas and near night lighting, it appears that exposure to artificial night lighting may lead to considerable developmental costs. Future research will need to consider the detrimental effects of ALAN combined with foraging benefits when studying nocturnal insectivores that forage around artificial lights. | ||||
