  Title Effects of photoperiod and light Spectrum on growth performance, digestive enzymes, hepatic biochemistry and peripheral hormones in spotted sea bass (Lateolabrax maculatus) Type Journal Article
  Year 2019 Publication (up) Aquaculture Abbreviated Journal Aquaculture  
  Volume in press Issue Pages  
  Keywords Animals  
  Abstract Growth performance, digestive and metabolic activities, and contents of peripheral hormones of spotted sea bass (Lateolabrax maculatus) juveniles were evaluated under natural light and three different light spectrums (white, blue and red) in combination with three photoperiods (light: dark cycle, 12: 12-h, 18: 6-h and 24: 0-h). Bass in 18-h blue light environment displayed the best growth performance and digestive enzyme activities, while red light environment significantly impeded growth and digestive enzyme activities. Altered contents of melatonin, cortisol, thyroid hormones (T3 and T4), and testosterone (T) were observed in bass reared in red light, suggesting that red light could disturb endocrine homeostasis associated with biological rhythm (melatonin), stress coping (melatonin and cortisol), growth and development (T3 and T4), and aggressive behavior or hyperactivity (T3, T4 and T). Impaired growth performance might be due to energy used to cope with stress. We concluded that the red spectrum environment was stressful to spotted bass and the selection of appropriate light conditions (such as 18-h blue light) might lead to a beneficial outcome for spotted sea bass culture.

  Title Artificial light at night: implications for early life stages development in four temperate freshwater fish species Type Journal Article
  Year 2011 Publication (up) Aquatic Sciences Abbreviated Journal Aquat Sci  
  Volume 73 Issue 1 Pages 143-152  
  Keywords Ecology  
  Abstract Flora and fauna have both evolved under a natural cycle of light and dark. But especially in urban areas, the night is now increasingly disturbed by artificial light. Many traits and behaviours in fish are triggered by a circadian clock, for example hatching and swim bladder inflation, which predominantly take place at dusk or night. As lighting becomes brighter and extends farther into rural areas, the distinction between day and night becomes increasingly blurred. Therefore, the loss of diurnal trigger by artificial light at night was hypothesized having deleterious effects on these traits and impact fish reproduction. To assess these effects, eggs of four native freshwater fishes, Eurasian perch Perca fluviatilis, roach Rutilus rutilus, bleak Alburnus alburnus and chub Leuciscus cephalus, were incubated under two different light conditions: a photoperiod of 14 h light:10 h darkness (LD) and continuous illumination (LL). The time to hatch and swim bladder inflation was recorded. The species showed inconsistent reactions to the light treatments. In roach and bleak, the time to 50% hatch was longer in LL, whereas continuous lighting had an accelerating effect in chub. Incubation in LL elongated the hatching period in perch and roach and, in perch, the onset of darkness seemed to trigger hatching. The swim bladder inflation was significantly promoted by continuous light in chub and bleak but was not affected in roach. In conclusion, nocturnal artificial illumination could have an effect on hatching and initial swim bladder filling by masking the day–night-change and thereby diminish the trigger effect. However, the reactions were species specific and the increase in variation indicated a lack of diurnal triggering, whilst a general deleterious effect of artificial light at night has not been identified on early life stages.

  Title Home Sweet Home. Connecting the dots for healthy evening residential illumination Type Journal Article
  Year 2019 Publication (up) ARC Lighting In Architecture Abbreviated Journal  
  Volume Issue Pages 55-60  
  Keywords Lighting; Human Health  
  Abstract During the twentieth century, lighting designers would commonly use incandescent light sources for residential homes as they provided a visual comfort, with high quality colour rendering properties, along with relaxing ambient atmosphere. Unfortunately, it’s now difficult to buy incandescent light sources because they have been banned in many countries (https://bit.ly/2GwN2Wv). This article addresses some of the challenges in regards to health, brought about by the changeover to new LEDs and other related technologies, and tries to offer some context on how to keep up with these rapid transformations. While we know it’s necessary to limit blue-rich light at night (as it prevents melatonin production and impaires nocturnal sleep), and that it’s important to maximise exposure to the blue wavelength of light in the morning (to trigger circadian timing, increase alertness), there are other issues that are misunderstood and often ignored. This includes flicker from LEDs and electromagnetic fields (EMFs), which can be produced by smart home lighting technology.

  Title Street Lighting and Public Safety: New Nighttime Lighting Documentation Method Type Journal Article
  Year 2018 Publication (up) ARCC Conference Repository Abbreviated Journal  
  Volume Issue Pages  
  Keywords Public Safety; Lighting  
  Abstract While the rapid transition of street lighting technologies is occurring across the country for its promising benefits of high energy efficiency, higher intensity, long lamp life, and low maintenance, there is a lack of understanding on the impacts from street lighting’s physical characteristics on public safety. Nighttime lighting and its impact on the incidence of crime and roadway accidents has been investigated since the 1960s in the United States and the United Kingdom. However, prior research has not presented any scientific evidence such as quantified lighting characteristic data and its impacts on public safety because they relied on subjective survey inputs or over-simplified quantification of nighttime lighting conditions. To overcome the limitation of previous studies, extensive documentation of street lighting characteristics was conducted in downtown San Antonio, Texas, which adopts both conventional and new street lighting technologies. Two different sets of light level data were collected on roadways in order to measure the amount of light falling on the ground and on drivers’ eyes inside a car. Correlated color temperature and a color rendering index of nighttime lighting were recorded. The collected lighting data was mapped in a Geographic Information Systems database in order to spatially analyze lighting characteristics. The paper first highlights the potential issues with lighting analysis in previous studies. Next, the proposed research methodology to address these issues for both data collection and spatial analyses is explained. Finally, the preliminary documentation and analysis of street lighting characteristics are presented.

  Title Prior exposure to dim light at night impairs dermal wound healing in female C57BL/6 mice Type Journal Article
  Year 2019 Publication (up) Archives of Dermatological Research Abbreviated Journal Arch Dermatol Res  
  Volume in press Issue Pages  
  Keywords Animals  
  Abstract Artificial light at night (LAN) is a pervasive phenomenon in today's society, and the detrimental consequences of LAN exposure are becoming apparent. LAN is associated with the increased incidence of metabolic disorders, cancers, mood alterations, and immune dysfunction in mammals. Consequently, we examined the effects of dim LAN (DLAN) on wound healing. Female C57BL/6 mice were housed for 3 weeks in DLAN or LD conditions prior to wounding. Following wounding, mice were maintained in either their previous light conditions or switched to the opposite lighting conditions for 3 weeks. DLAN prior to wounding impaired healing; specifically, mice in DLAN/DLAN had significantly larger wounds on day 8. Additionally, mice in DLAN/LD had significantly larger wounds on days 5, 7, 8, and 9, and increased average time to closure. These data demonstrate a potential harmful effect of DLAN on wound healing that should be considered and may represent a target for therapeutic intervention.
