  Title The preference and costs of sleeping under light at night in forest and urban great tits Type Journal Article
  Year 2019 Publication Proceedings. Biological Sciences Abbreviated Journal Proc Biol Sci  
  Volume 286 Issue 1905 Pages (down) 20190872  
  Keywords Animals  
  Abstract Artificial light at night (ALAN) is an increasing phenomenon associated with worldwide urbanization. In birds, broad-spectrum white ALAN can have disruptive effects on activity patterns, metabolism, stress response and immune function. There has been growing research on whether the use of alternative light spectra can reduce these negative effects, but surprisingly, there has been no study to determine which light spectrum birds prefer. To test such a preference, we gave urban and forest great tits (Parus major) the choice where to roost using pairwise combinations of darkness, white light or green dim light at night (1.5 lux). Birds preferred to sleep under artificial light instead of darkness, and green was preferred over white light. In a subsequent experiment, we investigated the consequence of sleeping under a particular light condition, and measured birds' daily activity levels, daily energy expenditure (DEE), oxalic acid as a biomarker for sleep debt and cognitive abilities. White light affected activity patterns more than green light. Moreover, there was an origin-dependent response to spectral composition: in urban birds, the total daily activity and night activity did not differ between white and green light, while forest birds were more active under white than green light. We also found that individuals who slept under white and green light had higher DEE. However, there were no differences in oxalic acid levels or cognitive abilities between light treatments. Thus, we argue that in naive birds that had never encountered light at night, white light might disrupt circadian rhythms more than green light. However, it is possible that the negative effects of ALAN on sleep and cognition might be observed only under intensities higher than 1.5 lux. These results suggest that reducing the intensity of light pollution as well as tuning the spectrum towards long wavelengths may considerably reduce its impact.

  Title Artificial light at night causes reproductive failure in clownfish Type Journal Article
  Year 2019 Publication Biology Letters Abbreviated Journal Biol. Lett.  
  Volume 15 Issue 7 Pages (down) 20190272  
  Keywords Animals  
  Abstract The Earth is getting brighter at night, as artificial light at night (ALAN) continues to increase and extend its reach. Despite recent recognition of the damaging impacts of ALAN on terrestrial ecosystems, research on ALAN in marine systems is comparatively lacking. To further our understanding of the impacts of ALAN on marine organisms, this study examines how the reproductive fitness of the common clownfish Amphiprion ocellaris is influenced by the presence of ALAN. We assessed how exposure to low levels of ALAN affects (i) frequency of spawning, (ii) egg fertilization success, and (iii) hatching success of A. ocellaris under control (12 : 12 day–night) and treatment (12 : 12 day–ALAN) light regimes. While we found exposure to ALAN had no impact on the frequency of spawning or fertilization success, ALAN had dramatic effects on hatching. Amphiprion ocellaris eggs incubated in the presence of ALAN simply did not hatch, resulting in zero survivorship of offspring. These findings suggest ALAN can significantly reduce reproductive fitness in a benthic-spawning reef fish. Further research in this field is necessary to fully understand the extent of this impact on population and community dynamics in the wild.

  Title Half a century of Lighting Research & Technology: A bibliometric review Type Journal Article
  Year 2019 Publication Lighting Research & Technology Abbreviated Journal Lighting Research & Technology  
  Volume in press Issue Pages (down) 1477153519857788  
  Keywords History; Lighting; Review  
  Abstract Lighting Research & Technology (LRT) is an influential journal in the field of light and lighting dating back to 1969. To celebrate its 50th birthday, the current study explored its bibliometric characteristics and mapped the bibliographic information graphically through VOSviewer software. This analysis found that the number of papers has steadily increased during recent years. The most productive and cited country was the United Kingdom. The most productive and cited institution was Rensselaer Polytechnic Institute. The most prolific author was Steve Fotios and the most cited author was Mark Rea. The journal most cited together with LRT was Leukos. LRT has become more and more international and interdisciplinary over the last five decades. Suggestions for the development of LRT are provided. Develpoments over the last 50 years have turned LRT into one of leading journals in the light and lighting field, one which has a bright future.

  Title Influence of green light illumination at night on biological characteristics of the oriental armyworm, Mythimna separata (Lepidoptera: Noctuidae) Type Journal Article
  Year 2019 Publication Bulletin of Entomological Research Abbreviated Journal Bull Entomol Res  
  Volume in press Issue Pages (down) S0007485319000397  
  Keywords Animals; Mythimna separata; biological characteristic; green light; longevity; reproduction  
  Abstract The oriental armyworm, Mythimna separata is an important crop pest in eastern Asia. Nocturnal insects, including nocturnal moths, have phototactic behavior to an artificial light source. Phototactic behavior in insects is species-specific in response to different wavelengths of light sources. Our previous study showed that green (520 nm) light emitting diode (LED) light resulted in a significantly higher phototactic behavior in M. separata moths compared to the other wavelength LED lights. The goal of the present study is to investigate the influence of green light illumination on biological characteristics of different developmental stages in M. separata. Our results revealed that when different developmental stages of M. separata were exposed to the green light illumination in a dark period, several biological characteristics in all developmental stages except for egg stage were positively changed, but those of F1 generation M. separata which are next generation of the adults exposed to the green light did not significantly change compared with the control level. These findings suggest that green light illumination at night (or dark period) has a positive effect on the development and longevity of M. separata.

  Title Analyzing the obstruction effects of obstacles on light pollution caused by street lighting system in Cambridge, Massachusetts Type Journal Article
  Year 2019 Publication Environment and Planning B: Urban Analytics and City Science Abbreviated Journal Environment and Planning B: Urban Analytics and City Science  
  Volume in press Issue Pages (down) 2399808319861645  
  Keywords Skyglow; Lighting; upward light  
  Abstract Artificial light has transformed urban life, enhancing visibility, aesthetics, and increasing safety in public areas. However, too much unwanted artificial light leads to light pollution, which has a negative effect on public health and urban ecosystems, as well as on the aesthetic and cultural meanings of the night sky. Some of the factors interfering with the estimation of light pollution in cities are urban features, such as the presence of trees, road dimensions, and the physical characteristics of buildings. In this study, we proposed a simplified model for unwanted upward light coming from street luminaires based on a building height model and the publicly accessible Google Street View images. We simulated and analyzed the obstruction effects of different street features on the light pollution caused by the street lighting system in Cambridge, Massachusetts. By providing quantitative information about the connections between the streetscape features and the amount of unwanted upward artificial light, this study provides reference values to inform policies aimed at curbing light pollution.
