  Title Effects of dimming light-emitting diode street lights on light-opportunistic and light-averse bats in suburban habitats Type Journal Article
  Year 2018 Publication Royal Society Open Science Abbreviated Journal R. Soc. open sci.  
  Volume 5 Issue 6 Pages (down) 180205  
  Keywords Animals; Lighting  
  Abstract Emerging lighting technologies provide opportunities for reducing carbon footprints, and for biodiversity conservation. In addition to installing light-emitting diode street lights, many local authorities are also dimming street lights. This might benefit light-averse bat species by creating dark refuges for these bats to forage and commute in human-dominated habitats. We conducted a field experiment to determine how light intensity affects the activity of the light-opportunistic Pipistrellus pipistrellus and light-averse bats in the genus Myotis. We used four lighting levels controlled under a central management system at existing street lights in a suburban environment (0, 25, 50 and 100% of the original output). Higher light intensities (50 and 100% of original output) increased the activity of light-opportunistic species but reduced the activity of light-averse bats. Compared to the unlit treatment, the 25% lighting level did not significantly affect either P. pipistrellus or Myotis spp. Our results suggest that it is possible to achieve a light intensity that provides both economic and ecological benefits by providing sufficient light for human requirements while not deterring light-averse bats.

  Title Night-time lights: A global, long term look at links to socio-economic trends Type Journal Article
  Year 2017 Publication PloS one Abbreviated Journal PLoS One  
  Volume 12 Issue 3 Pages (down) e0174610  
  Keywords Remote Sensing; Economics  
  Abstract We use a parallelized spatial analytics platform to process the twenty-one year totality of the longest-running time series of night-time lights data-the Defense Meteorological Satellite Program (DMSP) dataset-surpassing the narrower scope of prior studies to assess changes in area lit of countries globally. Doing so allows a retrospective look at the global, long-term relationships between night-time lights and a series of socio-economic indicators. We find the strongest correlations with electricity consumption, CO2 emissions, and GDP, followed by population, CH4 emissions, N2O emissions, poverty (inverse) and F-gas emissions. Relating area lit to electricity consumption shows that while a basic linear model provides a good statistical fit, regional and temporal trends are found to have a significant impact.

  Title Long-term exposure to constant light induces dementia, oxidative stress and promotes aggregation of sub-pathological Abeta42 in Wistar rats Type Journal Article
  Year 2020 Publication Pharmacology, Biochemistry, and Behavior Abbreviated Journal Pharmacol Biochem Behav  
  Volume in press Issue Pages (down) 172892  
  Keywords Animals; Amyloid beta; Behavior, fluoxetine, rifampicin; Oxidative stress  
  Abstract Constant exposure to light is prevalent in modern society where light noise, shift work, and jet lag is common. Constant light exposure disrupts circadian rhythm, induces stress and thus influences memory performance. We subjected adult male Wistar rats to a two-month exposure to constant light (LL), constant dark or normal light-dark cycles. Significant cognitive impairment and oxidative stress were observed in LL rats without a significant elevation in soluble Abeta1-42 levels. Next, we examined whether long-term exposure to constant light may accelerate dementia in a sub-pathological Abeta model of rats. Normal control rats received ACSF, AD rats received 440pmol, and sub-pathological Abeta rats (Abeta(s)) received 220pmol of human Abeta42 peptide in a single unilateral ICV administration. Sub-pathological Abeta rats exposed to constant light (LL+Abeta(s)) show significant memory deficits and oxidative damage, although not significantly different from LL rats. Additionally, constant light promoted aggregation of exogenous Abeta42 in LL+Abeta(s) rats shown by the presence of congophilic plaques. Furthermore, chronic fluoxetine treatment (5mg/kg/day) rescued rats from the behavioral deficits, oxidative damage and amyloid aggregation. Whereas, rifampicin treatment (20mg/kg/day) did not reverse the behavioral deficits or oxidative stress but rescued rats from amyloid plaque formation. It was concluded that constant light for two months induces behavioral deficits, oxidative stress, and accelerates aggregation of sub-pathological concentrations of human-Abeta42 peptides in Wistar rats, which is reversed by daily fluoxetine administration.

  Title Exposure of tropical ecosystems to artificial light at night: Brazil as a case study Type Journal Article
  Year 2017 Publication PloS one Abbreviated Journal PLoS One  
  Volume 12 Issue 2 Pages (down) e0171655  
  Keywords Remote Sensing  
  Abstract Artificial nighttime lighting from streetlights and other sources has a broad range of biological effects. Understanding the spatial and temporal levels and patterns of this lighting is a key step in determining the severity of adverse effects on different ecosystems, vegetation, and habitat types. Few such analyses have been conducted, particularly for regions with high biodiversity, including the tropics. We used an intercalibrated version of the Defense Meteorological Satellite Program's Operational Linescan System (DMSP/OLS) images of stable nighttime lights to determine what proportion of original and current Brazilian vegetation types are experiencing measurable levels of artificial light and how this has changed in recent years. The percentage area affected by both detectable light and increases in brightness ranged between 0 and 35% for native vegetation types, and between 0 and 25% for current vegetation (i.e. including agriculture). The most heavily affected areas encompassed terrestrial coastal vegetation types (restingas and mangroves), Semideciduous Seasonal Forest, and Mixed Ombrophilous Forest. The existing small remnants of Lowland Deciduous and Semideciduous Seasonal Forests and of Campinarana had the lowest exposure levels to artificial light. Light pollution has not often been investigated in developing countries but our data show that it is an environmental concern.

  Title Comment on 'Age of enlightenment: long-term effects of outdoor aesthetic lights on bats in churches' Type Journal Article
  Year 2017 Publication Royal Society Open Science Abbreviated Journal R. Soc. open sci.  
  Volume 4 Issue 11 Pages (down) 171312  
  Keywords Animals  
  Abstract This comment reanalyses the data presented in Rydell (Rydell 2017 R. Soc. open. sci. 4, 161077. (doi:10.1098/rsos.161077)) which were analysed using only very basic statistics like Fisher’s exact test and McNemar’s test. We demonstrate how the use of more advanced statistical methods can make better use of the available data, quantify the observed effects and strengthen the conclusions in Rydell (Rydell 2017 R. Soc. open. sci. 4, 161077. (doi:10.1098/rsos.161077)). We have no intention to discredit the original authors. Their analyses were basic but correct.
