  Title Estimation of the anthropogenic heat release distribution in China from 1992 to 2009 Type Journal Article
  Year 2012 Publication (up) Acta Meteorologica Sinica Abbreviated Journal Acta Meteorol Sin  
  Volume 26 Issue 4 Pages 507-515  
  Keywords DMSP/OLS; estimation; distribution; anthropogenic heat flux; China; remote sensing  
  Abstract Stable light data from Defense Meteorological Satellite Program (DMSP)/Operational Linescan System (OLS) satellites and authoritative energy consumption data distributed by National Bureau of Statistics of China were applied to estimating the distribution of anthropogenic heat release in China from 1992 to 2009. A strong linear relationship was found between DMSP/OLS digital number data and anthropogenic heat flux density (AHFD). The results indicate that anthropogenic heat release in China was geographically concentrated and was fundamentally correlated with economic activities. The anthropogenic heat release in economically developed areas in northern, eastern, and southern China was much larger than other regions, whereas it was very small in northwestern and southwestern China. The mean AHFD in China increased from 0.07 W m−2 in 1978 to 0.28 W m−2 in 2008. The results indicate that in the anthropogenic heat-concentrated regions of Beijing, the Yangtze River Delta, and the Pearl River Delta, the AHFD levels were much higher than the average. The effect of aggravating anthropogenic heat release on climate change deserves further investigation.

  Title Effects of artificial illumination on the nocturnal foraging of waders Type Journal Article
  Year 2010 Publication (up) Acta Oecologica Abbreviated Journal Acta Oecologica  
  Volume 36 Issue 2 Pages 166-172  
  Keywords waders; light pollution; animals  
  Abstract Large areas of natural and semi-natural habitats are exposed to artificial illumination from adjacent urban areas and roads. Estuarine and coastal wetlands are particularly exposed to such illumination because shorelines often are heavily utilized by man. However, the impact of artificial illumination on the waders that forage in these highly productive habitats is virtually unknown. We evaluated the effects of artificial illumination on the nocturnal habitat selection and foraging behaviour of six wader species with different feeding strategies: three visual foragers, two species that alternate visual and tactile strategies (mixed foragers), and one tactile forager. We quantified the number of birds and their foraging behaviour at sites affected and not affected by streetlights, and also before and after illuminating experimental sites. Areas illuminated by streetlights were used more during the night by visual foragers, and to a lesser extent by mixed foragers, than non-illuminated areas. Visual foragers increased their foraging effort in illuminated areas, and mixed foragers changed to more efficient visual foraging strategies. These behavioural shifts improved prey intake rate by an average of 83% in visual and mixed foragers. We have showed that artificial illumination has a positive effect on the nocturnal foraging of waders, but on the other hand may draw them to degraded areas close to urban centres, and potentially raises their exposure to predators. Our findings suggest that artificial illumination is worth investigation as a tool in the management of intertidal habitats for waders.

  Title Early changes in gene expression induced by blue light irradiation of A2E-laden retinal pigment epithelial cells Type Journal Article
  Year 2013 Publication (up) Acta Ophthalmologica Abbreviated Journal Acta Ophthalmol

  Abstract PURPOSE: Accumulation of bisretinoids as lipofuscin in retinal pigment epithelial (RPE) cells is implicated in the pathogenesis of some blinding diseases including age-related macular degeneration (AMD). To identify genes whose expression may change under conditions of bisretinoid accumulation, we investigated the differential gene expression in RPE cells that had accumulated the lipofuscin fluorophore A2E and were exposed to blue light (430 nm). METHODS: A2E-laden RPE cells were exposed to blue light (A2E/430 nm) at various time intervals. Cell death was quantified using Dead Red staining, and RNA levels for the entire genome was determined using DNA microarrays (Affymetrix GeneChip Human Genome 2.0 Plus). Array results for selected genes were confirmed by real-time reverse-transcriptase polymerase chain reaction. RESULTS: Principal component analysis revealed that the A2E-laden RPE cells irradiated with blue light were clearly distinguishable from the control samples. We found differential regulation of genes belonging to the following functional groups: transcription factors, stress response, apoptosis and immune response. Among the last mentioned were downregulation of four genes that coded for proteins that have an inhibitory effect on the complement cascade: (complement factor H, complement factor H-related 1, complement factor I and vitronectin) and of two belonging to the classical pathway (complement component 1, s subcomponent and complement component 1, r subcomponent). CONCLUSION: This study demonstrates that blue light irradiation of A2E-laden RPE cells can alter the transcription of genes belonging to different functional pathways including stress response, apoptosis and the immune response. We suggest that these molecules may be associated to the pathogenesis of AMD and can potentially serve as future therapeutic targets.

  Title Stomatal movements depend on interactions between external night light cue and internal signals activated by rhythmic starch turnover and abscisic acid (ABA) levels at dawn and dusk Type Journal Article
  Year 2017 Publication (up) Acta Physiologiae Plantarum Abbreviated Journal Acta Physiol Plant  
  Volume 39 Issue 8 Pages  
  Keywords Plants  
  Abstract Yellow poplar (Liriodendron tulipifera L.) is a widespread hardwood tree of great ecological and economic value. Light pollution caused by excessive and indiscriminate exposure to artificial night light has emerged as a new risk factor due to its adverse effects related to energy waste, sleep disorders, anthropogenic habitat disturbance, and perceptual disorder of daily and seasonal rhythms in wildlife. However, it remains unknown how associations between artificial night light and stomatal behaviors controlled by internal signals are established. After continuous exposure to artificial light at night over 3 years, leaves in the experimental set-up were measured for stomatal movements, starch turnover, endogenous abscisic acid (ABA) levels, and chloroplast ultrastructure during the growing season. Yellow poplar showed dynamic changes in stomatal movement, starch turnover, and endogenous ABA levels in response to day/artificial night light cycle, resulting in reduction of circadian phase-shifting capacity at both dusk and dawn and normal chloroplast development as compared with natural night. Nighttime light exposure may act as a major factor for disorder of circadian and circannual rhythms as well as physiological and ultrastructural repressor in plants, via a modification of the perceived photoperiod. Our study suggests that these dynamic responses can provide advantageous insights that complement the current knowledge on light pollution.

  Title The influence of light on thermal responses Type Journal Article
  Year 2015 Publication (up) Acta Physiologica (Oxford, England) Abbreviated Journal Acta Physiol (Oxf)  
  Volume 216 Issue 2 Pages 163–185  
  Keywords Phsychology; Human Health  
  Abstract Light is essential for vision and plays an important role in non-visual responses, thus affecting alertness, mood and circadian rhythms. Furthermore, light influences physiological processes, such as thermoregulation, and therefore may be expected to play a role in thermal comfort as well. A systematic literature search was performed for human studies exploring the relation between ocular light exposure, thermophysiology and thermal comfort. Experimental results show that light in the evening can reduce melatonin secretion, delay the natural decline in core body temperature (CBT), and slow down the increase in distal skin temperature. In the morning though, bright light can result in a faster decline of melatonin levels, thus enabling a faster increase in CBT. Moreover the colour of light can affect temperature perception of the environment. Light with colour tones towards the red-end of the visual spectrum leads to a warmer perception compared to more bluish light tones. It should be noted however, that many results of light on thermal responses are inconclusive, and a theoretical framework is largely lacking. In conclusion, light is capable of evoking thermophysiological responses and visual input can alter perception of the thermal environment. Therefore lighting conditions should be taken in consideration during thermophysiological research and in the design of indoor climates. This article is protected by copyright. All rights reserved.
