  Title Signaling cascades and the importance of moonlight in coral broadcast mass spawning Type Journal Article
  Year 2015 Publication eLife Abbreviated Journal  
  Volume 4 Issue Pages e09991  
  Keywords Animals; coral; chronobiology; reproductive strategies; reproductive synchronization; Great Barrier Reef; neurohormones; marine; oceans; invertebrates  
  Abstract Many reef-building corals participate in a mass-spawning event that occurs yearly on the Great Barrier Reef. This coral reproductive event is one of earth's most prominent examples of synchronised behavior, and coral reproductive success is vital to the persistence of coral reef ecosystems. Although several environmental cues have been implicated in the timing of mass spawning, the specific sensory cues that function together with endogenous clock mechanisms to ensure accurate timing of gamete release are largely unknown. Here, we show that moonlight is an important external stimulus for mass spawning synchrony and describe the potential mechanisms underlying the ability of corals to detect environmental triggers for the signaling cascades that ultimately result in gamete release. Our study increases the understanding of reproductive chronobiology in corals and strongly supports the hypothesis that coral gamete release is achieved by a complex array of potential neurohormones and light-sensing molecules.

  Title Measurement of Light Pollution Type Book Chapter
  Year 2014 Publication Methods of Measuring Environmental Parameters Abbreviated Journal  
  Volume Chapter 33 Issue Pages  
  Keywords Bortle scale; digital photography; light pollution; portable spectrophotometer; sky quality meter; SQM  
  Abstract Digital photography is based on the conversion of light by sensitive matrix (array of electronic photodetectors) to capture the image which is then digitized and stored as a computer file for further processing and printing. The spectral sensitivity of the cameras is in good agreement with the spectrum of action of the photosensitive hormone melatonin. Digital photography can be used to quantify light pollution acting on the physiology of living organisms. The chapter discusses the principles of spectrophotometry. A portable spectrophotometer for the measurement of light pollution is proposed by Cinzano. It consists of a cooled CCD camera and a small spectrographic head which is equipped with a De Amici prism composed of two external crown prisms and an inner Flint prism. Sky quality meter (SQM) is a portable photometer for measuring sky brightness and for light pollution monitoring. This device collects the light from a wide solid angle.

  Title Night Landscapes: A Challenge to World Heritage Protocols Type Journal Article
  Year 2014 Publication Landscape Review Abbreviated Journal Landscape Rev.  
  Volume 15 Issue 1 Pages 64-75  
  Keywords land management; starlight reserve; dark sky reserve; International Dark Sky Association; world heritage; landscape; parks  
  Abstract Starlight reserves are a relatively new concept whose definition and management protocols have come about in an era when understandings of human relationships with nature are dynamic and infused with cultural meaning. Rather than assuming that pristine nature can be sealed off from human influences, World Heritage guidelines now accept that our experience of nature may be enriched by attention to the multifunctional landscape, in which a blend of aesthetic, historical, cultural, scientific and environmental elements are carefully presented to tourists. Observatories and clear night skies are ideal sites for such an interface, and the loss of dark skies has led to new systems of audit aimed at their preservation. This

study of the potential for a World Heritage Site in the Mackenzie Basin, in the South Island of New Zealand, grounds the interaction between World Heritage goals and management of land use in a place where exceptional sky quality and competing land uses challenge multiple stakeholders to rethink their concepts of landscape

  Title Artificial light as a disturbance to light-naïve streams Type Journal Article
  Year 2014 Publication Freshwater Biology Abbreviated Journal Freshw Biol  
  Volume 59 Issue 11 Pages 2235–2244  
  Keywords cutthroat trout; drift; invertebrates; light pollution; urbanization; *Fishes; Oncorhynchus clarkii; British Columbia  
  Abstract Summary

Artificial light at night is prevalent in human-dominated landscapes, and streams in these landscapes can be expected to be affected by artificial lights. We hypothesised that artificial light at night would reduce the activity of aquatic insects, resulting in reduced drift rates, lower fish growth rates and lower leaf litter decomposition rates.

We tested these hypotheses by installing street lights to reaches in four forested, natural streams of coastal British Columbia each paired with a control reach. Cutthroat trout (Oncorhynchus clarkii) are the top predators in these streams and feed mostly on terrestrial and drifting aquatic invertebrates.

We found that the night-time drift of aquatic invertebrates in lit reaches was ˜50% of the drift in dark reaches. However, the density of emerging aquatic insects, the density of insects falling into reaches, leaf litter decomposition rate and the number and growth rate of trout caught were not significantly different between the dark and experimentally lit reaches.

We conclude that, while short-term exposure to artificial light during the summer changes invertebrate behaviour, it does not significantly alter other trophic levels in forested headwater streams. Our results suggest that low levels of artificial light do not strongly influence stream ecosystems, but future research should determine whether this is true for all seasons and longer-term exposure to light.

  Title Harmful effects on organism induced by light of different wavelength and power Type Journal Article
  Year 2014 Publication Optik Abbreviated Journal Optik  
  Volume 125 Issue 19 Pages 5808-5812  
  Keywords LED; Wavelength; Power; Microvessel; Absorption spectrum  
  Abstract Although a variety of experiments on light exposure stress to animals significantly affect the retina and circulation system, it is still unknown the relationship between the different extent of harmful effect on organism and light with different wavelengths and power. This study is aimed to investigate the changes to microblood vessel and the variations in serum absorption spectrum. LED light of different wavelength and power were used. The results show that power has a relatively larger impact on physiological indexes than wavelength. The extents of these variations are relatively different according to the regression equations. All of these stimulations cause damage to mice physiological conditions, producing some extent of light pollution. The research findings supply the guideline for the effective prevention of the harmful effect on organism by light pollution from the view of science of optical life science.
