  Title Light-at-Night-Induced Circadian Disruption, Cancer and Aging Type Journal Article
  Year 2012 Publication Current Aging Science Abbreviated Journal (up)  
  Volume 5 Issue 3 Pages 170-177  
  Keywords Animals; Light-at-night; aging; cancer; cardiovascular diseases; circadian; circadian rhythm; diabetes; disruption; melatonin; shift-work  
  Abstract Light-at-night has become an increasing and essential part of the modern lifestyle and leads to a number of health problems, including excessive body mass index, cardiovascular diseases, diabetes, and cancer. The International Agency for Research on Cancer (IARC) Working Group concluded that “shift-work that involves circadian disruption is probably carcinogenic to humans” (Group 2A) [1]. According to the circadian disruption hypothesis, light-at-night might disrupt the endogenous circadian rhythm and specifically suppress nocturnal production of the pineal hormone melatonin and its secretion into the blood. We evaluated the effect of various light/dark regimens on the survival, life span, and spontaneous and chemical carcinogenesis in rodents. Exposure to constant illumination was followed by accelerated aging and enhanced spontaneous tumorigenesis in female CBA and transgenic HER-2/neu mice. In male and female rats maintained at various light/dark regimens (standard 12:12 light/dark [LD], the natural light [NL] of northwestern Russia, constant light [LL], and constant darkness [DD]) from the age of 25 days until natural death, it was found that exposure to NL and LL regimens accelerated age-related switch-off of the estrous function (in females), induced development of metabolic syndrome and spontaneous tumorigenesis, and shortened life span both in male and females rats compared to the standard LD regimen. Melatonin given in nocturnal drinking water prevented the adverse effect of the constant illumination (LL) and natural light (NL) regimens on the homeostasis, life span, and tumor development both in mice and rats. The exposure to the LL regimen accelerated colon carcinogenesis induced by 1,2-dimethylhydrazine (DMH) in rats, whereas the treatment with melatonin alleviated the effects of LL. The maintenance of rats at the DD regimen inhibited DMH-induced carcinogenesis. The LL regimen accelerated, whereas the DD regimen inhibited both mammary carcinogenesis induced by N-nitrosomethylurea and transplacental carcinogenesis induced by N-nitrosoethylurea in rats. Treatment with melatonin prevented premature aging and tumorigenesis in rodents. The data found in the literature and our observations suggest that the use of melatonin would be effective for cancer prevention in humans at risk as a result of light pollution.

  Title Red aviation lights on wind turbines do not increase bat-turbine collisions Type Journal Article
  Year 2014 Publication Animal Conservation Abbreviated Journal (up)  
  Volume 17 Issue 4 Pages 354-358  
  Keywords animals; flying mammals; foraging; Light wavelength  
  Abstract Many hypotheses have been proposed to explain why bat–wind turbine collisions occur; however, most of these hypotheses have yet to be tested and with high numbers of bat fatalities reported annually at wind resource facilities globally, there is a real need to understand this phenomenon. In this study, we tested whether aviation lighting influenced the number of bat fatalities at wind turbines. Thus, at a utility-scale wind facility in north-central Texas, we explored whether bat fatalities were higher at wind turbines with red flashing aviation lighting compared with turbines without such lighting. Over a 5-year period, we recorded fatalities at wind turbines as part of a long-term fatality monitoring programme. During standardized searches, we collected 916 bat carcasses representing all six species known to be present at the site. We found that bat fatalities were higher at wind turbines without aviation lighting compared with those with; a pattern that was driven by one species, Lasiurus borealis, and there was no significant difference between fatalities at wind turbines with or without aviation lighting for any other species. Our study demonstrates that wind turbines should continue to be fitted with synchronized, flashing red aviation lights, as this form of lighting does not appear to be one of the potential causes of bat fatalities at wind resource facilities. We therefore support further research that explores possible alternative causes of bat–wind turbine interactions. More specifically, we reiterate that there is still a pressing need to determine the aspects of bat ecology that result in individuals coming into contact with wind turbines.

  Title Assessment of predation risk via illumination level: facultative central place foraging in the cricetid rodent Phyllotis darwini Type Journal Article
  Year 1994 Publication Behavioral Ecology and Sociobiology Abbreviated Journal (up)  
  Volume 34 Issue 5 Pages 375-381  
  Keywords animals; rodents; foraging behaviour  
  Abstract It is well known that the risk of predation affects prey decision making. However, few studies have been concerned with the cues used by prey to assess this risk. Prey animals may use indirect environmental cues to assess predation hazard since direct evaluation may be dangerous. I studied the assessment of predation risk, manipulated via environmental illumination level, and the trade-off between foraging and predation hazard avoidance in the nocturnal rodent Phyllotis darwini (Rodentia: Cricetidae). In experimental arenas I simulated dark and full moon nights (which in nature correlate with low and high predation risk, respectively) and measured the immediate responses of animals to flyovers of a raptor model. Second, varying illumination only, I evaluated patch use, food consumption, central place foraging, and nocturnal variation of body weight. During flyover experiments, animals showed significantly more evasive reactions under full moon illumination than in moonless conditions. In the patch use experiments, rodents significantly increased their giving-up density and decreased their total food consumption under moonlight. On dark nights, rodents normally fed in the food patch, but when illumination was high they became central place foragers in large proportion. Moreover, the body weight of individuals decreased proportionately more during bright nights. These results strongly suggest that P. darwini uses the level of environmental illumination as a cue to the risk of being preyed upon and may sacrifice part of its energy return to avoid risky situations.

  Title Effects of light on aging and longevity Type Journal Article
  Year 2019 Publication Ageing Research Reviews Abbreviated Journal (up) Ageing Res Rev  
  Volume 53 Issue Pages 100913  
  Keywords Human Health; Review; Aging; longevity  
  Abstract Increasing evidence suggests an important role for light in regulation of aging and longevity. UV radiation is a mutagen that can promote aging and decrease longevity. In contrast, NIR light has shown protective effects in animal disease models. In invertebrates, visible light can shorten or extend lifespan, depending on the intensity and wavelength composition. Visible light also impacts human health, including retina function, sleep, cancer and psychiatric disorders. Possible mechanisms of visible light include: controlling circadian rhythms, inducing oxidative stress, and acting through the retina to affect neuronal circuits and systems. Changes in artificial lighting (e.g., LEDs) may have implications for human health. It will be important to further explore the mechanisms of how light affects aging and longevity, and how light affects human health.
