  Title Investigating the impact of street lighting changes on garden moth communities Type Journal Article
  Year 2016 Publication Journal of Urban Ecology Abbreviated Journal J Urban Ecol  
  Volume 2 Issue 1 Pages juw004  
  Keywords Animals  
  Abstract Night time illumination of cities is undergoing radical change through the adoption of new street lighting technologies, but the impacts of these large-scale changes on biodiversity have not been explored. Moths are of particular concern because of their nocturnal ‘flight-to-light’ responses. Here we examine in situ effects of (1) street lamp replacement and (2) the spatial distribution of local street lighting on garden moth communities in Birmingham, UK, to determine whether current shifts in street lighting infrastructure are leading to an increased attraction of moths into suburban areas. Using a unique before-after-control-impact survey, we show that switching from narrow (low-pressure sodium) to broad spectrum (high-pressure sodium) lamps significantly increases the diversity of macro-moths in suburban gardens. Furthermore, we demonstrate the complex ways in which the moth community differentially responds to variation in street lighting characteristics. In particular we found that macro-moth attraction was greatest at high lamp densities, whilst micro-moth families responded more strongly to street lamp proximity and the density of UV-emitting lamps specifically. Our findings indicate that moths are attracted to suburban gardens with closer, more dense and more spectrally diverse local street lighting, and suggest that suburban areas could represent ecological traps for moth communities if they have insufficient resources to support moth survival and reproduction. Further research is now needed to determine whether street lighting is progressively damaging moth communities, and to understand whether these impacts could be mitigated through changes to street lighting regimes or through the provision of ecologically important habitats in urban landscapes.

  Title Mayflies are least attracted to vertical polarization: A polarotactic reaction helping to avoid unsuitable habitats Type Journal Article
  Year 2016 Publication Physiology & Behavior Abbreviated Journal Physiol Behav  
  Volume 163 Issue Pages 219-227  
  Keywords Animals  
  Abstract Like other aquatic insects, mayflies are positively polarotactic and locate water surfaces by means of the horizontal polarization of water-reflected light. However, may vertically polarized light also have implications for the swarming behaviour of mayflies? To answer this question, we studied in four field experiments the behavioural responses of Ephoron virgo and Caenis robusta mayflies to lamps emitting horizontally and vertically polarized and unpolarized light. In both species, unpolarized light induces positive phototaxis, horizontally polarized light elicits positive photo- and polarotaxis, horizontally polarized light is much more attractive than unpolarized light, and vertically polarized light is the least attractive if the stimulus intensities and spectra are the same. Vertically polarized light was the most attractive for C. robusta if its intensity was about two and five times higher than that of the unpolarized and horizontally polarized stimuli, respectively. We suggest that the mayfly behaviour observed in our experiments may facilitate the stability of swarming above water surfaces. Beside the open water surface reflecting horizontally polarized light, the shadow and mirror image of riparian vegetation at the edge of the water surface reflect weakly and non-horizontally (mainly vertically) polarized light. Due to their positive polarotaxis, flying mayflies remain continuously above the water surface, because they keep away from the unpolarized or non-horizontally polarizing edge regions (water surface and coast line) of water bodies. We also discuss how our findings can explain the regulation of mayfly colonization.

  Title A new method to manipulate broiler chicken growth and metabolism: Response to mixed LED light system Type Journal Article
  Year 2016 Publication Scientific Reports Abbreviated Journal Sci Rep  
  Volume 6 Issue Pages 25972  
  Keywords Animals  
  Abstract Present study introduced a new method to manipulate broiler chicken growth and metabolism by mixing the growth-advantage LED. We found that the green/blue LED mixed light system (G-B and G x B) have the similar stimulatory effect on chick body weight with single green light and single blue light (G and B), compared with normal artificial light (P = 0.028). Moreover, the percentage of carcass was significantly greater in the mixed light (G x B) when compared with the single light (P = 0.003). Synchronized with body weight, the mixed light (G-B and G x B) had a significant improved influence on the feed conversion of birds compared with normal light (P = 0.002). A significant improvement in feed conversion were found in mixed light (G x B) compared with single LED light (P = 0.037). G group resulted in a greater high-density lipoprotein cholesterol level than B group (P = 0.002), whereas B group resulted in a greater low-density lipoprotein cholesterol level than G group (P = 0.017). The mixed light significantly increased the birds' glucose level in comparison with the single light (P = 0.003). This study might establish an effective strategy for maximizing growth of chickens by mixed LED technology.

  Title The emergence of modern lighting in Canada: A preliminary reconnaissance Type Journal Article
  Year 2016 Publication The Extractive Industries and Society Abbreviated Journal The Extractive Industries and Society  
  Volume 3 Issue 3 Pages 850-863  
  Keywords History  
  Abstract Recent work in the international field of energy history emphasizes the diversity that defines industrialization around the world, and even within different energy sectors of the same country. Energy history is a newly emerging field in Canada, and one where recent preliminary research now makes it possible to venture into the area of comparative energy studies. This paper provides a preliminary reconnaissance of the emergence of modern lighting in Canada, situating its history within the country’s larger idiosyncratic transition from the organic to the mineral energy regime. Canadians have always been among the world's highest energy consumers per capita, and they made a relatively late transition to the industrial regime. The country’s cold environment, its dispersed settlement patterns, the persistence of a distinct rural political economy supported by an abundance of energy from the organic regime, as well as the absence of cheap coal in Central Canada, help to explain the country’s distinctive characteristics. The history of lighting, however, is an exception within Canadian energy history: locally available, petroleum-based illuminating oil and stateowned hydroelectricity were adopted relatively early, comprising an exception within Canada’s late-modernizing trend: lighting, and not heat or power, led the country’s transition to the modern energy regime.

  Title Nutrition in the spotlight: metabolic effects of environmental light Type Journal Article
  Year 2016 Publication The Proceedings of the Nutrition Society Abbreviated Journal Proc Nutr Soc  
  Volume 75 Issue 4 Pages 451-463  
  Keywords Animals; Human Health  
  Abstract Use of artificial light resulted in relative independence from the natural light-dark (LD) cycle, allowing human subjects to shift the timing of food intake and work to convenient times. However, the increase in artificial light exposure parallels the increase in obesity prevalence. Light is the dominant Zeitgeber for the central circadian clock, which resides within the hypothalamic suprachiasmatic nucleus, and coordinates daily rhythm in feeding behaviour and metabolism. Eating during inappropriate light conditions may result in metabolic disease via changes in the biological clock. In this review, we describe the physiological role of light in the circadian timing system and explore the interaction between the circadian timing system and metabolism. Furthermore, we discuss the acute and chronic effects of artificial light exposure on food intake and energy metabolism in animals and human subjects. We propose that living in synchrony with the natural daily LD cycle promotes metabolic health and increased exposure to artificial light at inappropriate times of day has adverse effects on metabolism, feeding behaviour and body weight regulation. Reducing the negative side effects of the extensive use of artificial light in human subjects might be useful in the prevention of metabolic disease.
