Title Effects of television luminance and wavelength at habitual bedtime on melatonin and cortisol secretion in humans: Blue light and melatonin secretion Type Journal Article
Year 2015 Publication Sleep and Biological Rhythms Abbreviated Journal Sleep and Biological Rhythms
Volume 13 Issue 4 Pages 316–322
Keywords Human Health
Abstract The aim of this study was to examine the effect of exposure to different types of television displays at habitual bedtime on human melatonin and cortisol secretion. Thirteen male participants (mean age: 22.7 ± 0.85 years) were tested over three nights in one baseline and two experimental sessions. Participants were instructed to watch a movie on four different luminance- and wavelength-controlled television displays: normal luminance (450 candela [cd]/m2) or high luminance (1200 cd/m2) and normal blue light or half blue light. Salivary melatonin and cortisol levels were measured at two time points before and after television viewing. There was no significant difference in cortisol secretion due to the different displays. Melatonin suppression was significantly lower following the exposure to the half-blue light display compared with the normal blue light display. These results suggest that the use of half-blue light displays during night time may prevent circadian rhythm dysfunction.

Title Bright lights, big city: influences of ecological light pollution on reciprocal stream-riparian invertebrate fluxes Type Journal Article
Year 2013 Publication Ecological Applications Abbreviated Journal Ecological Applications
Volume 23 Issue 6 Pages 1322-1330
Keywords ecological light pollution; ecosystem function; stream–riparian invertebrate fluxes; tetragnathid spiders; urban streams
Abstract Cities produce considerable ecological light pollution (ELP), yet the effects of artificial night lighting on biological communities and ecosystem function have not been fully explored. From June 2010 to June 2011, we surveyed aquatic emergent insects, riparian arthropods entering the water, and riparian spiders of the family Tetragnathidae at nine stream reaches representing common ambient ELP levels of Columbus, Ohio, USA, streams (low, 0.1–0.5 lux; moderate, 0.6–2.0 lux; high, 2.1–4.0 lux). In August 2011, we experimentally increased light levels at the low- and moderate-treatment reaches to 10–12 lux to represent urban streams exposed to extremely high levels of ELP. Although season exerted the dominant influence on invertebrate fluxes over the course of the year, when analyzed by season, we found that light strongly influenced multiple invertebrate responses. The experimental light addition resulted in a 44% decrease in tetragnathid spider density (P = 0.035), decreases of 16% in family richness (P = 0.040) and 76% in mean body size (P = 0.022) of aquatic emergent insects, and a 309% increase in mean body size of terrestrial arthropods (P = 0.015). Our results provide evidence that artificial light sources can alter community structure and ecosystem function in streams via changes in reciprocal aquatic–terrestrial fluxes of invertebrates.

Title The effect of light on induced egg laying in the simultaneous hermaphrodite Lymnaea stagnalis Type Journal Article
Year 2012 Publication Journal of Molluscan Studies Abbreviated Journal Journal of Molluscan Studies
Volume 78 Issue 3 Pages 262-267
Keywords molluscs; Lymnaea stagnalis; reproduction
Abstract Reproduction is influenced by many external factors. For egg laying of pond snails, one important trigger is the transfer from dirty, oxygen-poor water to clean, oxygen-rich water. This response is due to the combined effects of elevated oxygen level, chemical water composition and clean substrate. Whether this clean-water stimulus (CWS) resembles the natural egg-laying process has remained untested. Given that the response relies heavily on a pretreatment that suppresses egg laying, the animal's internal state is clearly important. Egg laying is known to be influenced by day length, hence external factors signifying time of day or season may be involved. We here study the effect of light on the CWS in the freshwater pulmonate Lymnaea stagnalis. Clean water was more effective in inducing oviposition in the light than during darkness, irrespective of the presence of eyes. Thus, light has a profound influence on egg laying, which is most likely mediated by nonocular photoreceptors. We show that more eggs are laid during the day than during the night in wild-caught animals kept outside, which indicates that the effect of light on CWS-induced egg laying is relevant for the induction of egg laying under natural conditions.
