  Title Artificial light at night alter the impact of arsenic on microbial decomposers and leaf litter decomposition in streams Type Journal Article
  Year 2019 Publication Ecotoxicology and Environmental Safety Abbreviated Journal Ecotoxicol Environ Saf  
  Volume in press Issue Pages 110014  
  Keywords Ecology; Microbes; Fungal communities and biodiversity; Illumina sequencing; Light pollution; Litter decomposition; Microbiological oxidation  
  Abstract (up) Artificial light at night (ALAN, also known as light pollution) has been proved to be a contributor to environmental change and a biodiversity threat worldwide, yet little is known about its potential interaction with different metal pollutants, such as arsenic (As), one of the largest threats to aquatic ecosystems. To narrow this gap, an indoor microcosm study was performed using an ALAN simulation device to examine whether ALAN exposure altered the impact of arsenic on plant litter decomposition and its associated fungi. Results revealed that microbial decomposers involved in the conversion of As(III) to As(V), and ALAN exposure enhanced this effect; ALAN or arsenic only exposure altered fungal community composition and the correlations between fungi species, as well as stimulated or inhibited litter decomposition, respectively. The negative effects of arsenic on the decomposition of Pterocarya stenoptera leaf litter was alleviated by ALAN resulting in the enhanced photodegradation of leaf litter lignin and microbiological oxidation of As(III) to As(V), the increased microbial biomass and CBH activity, as well as the enhanced correlations between CBH and litter decomposition rate. Overall, results expand our understanding of ALAN on environment and highlight the contribution of ALAN to the toxicity of arsenic in aquatic ecosystems.

  Title Light Pollution Changes the Toxicological Effects of Cadmium on Microbial Community Structure and Function Associated with Leaf Litter Decomposition Type Journal Article
  Year 2020 Publication International Journal of Molecular Sciences Abbreviated Journal Int J Mol Sci  
  Volume 21 Issue 2 Pages  
  Keywords Plants; Illumina Sequencing; artificial light at night; cadmium pollution; extracellular enzyme activities; litter decomposition; microbial biodiversity  
  Abstract (up) Artificial light at night (ALAN/A) can not only alter the behavior and communication of biological organisms, it can also interact with other stressors. Despite its widespread use and the numerous potential ecological effects, little is known about the impact of ALAN on plant litter decomposition under cadmium (Cd) pollution in aquatic ecosystems. In an indoor microcosm experiment, we tested single and combined effects of ALAN and Cd on the activities and community structure of fungi associated with plant litter. The results showed that ALAN and/or Cd can change both water and leaf litter characteristics. ALAN exposure not only altered fungal community structure and their correlations, but also increased the activities of alkaline phosphatase, beta-glucosidase, and cellobiohydrolase. The leaf litter decomposition rate was 71% higher in the A-Cd treatment than that in the N-Cd treatment, indicating that the presence of ALAN weakened the negative impact of Cd on leaf litter decomposition. These results suggested that ALAN exposure mitigated the negative effect of Cd on leaf litter decomposition, contributing to the duel effect of ALAN on leaf litter decomposition. Overall, the results expand our understanding of ALAN on the environment and highlight the contribution of ALAN to Cd toxicity in aquatic ecosystems.

  Title Prior exposure to dim light at night impairs dermal wound healing in female C57BL/6 mice Type Journal Article
  Year 2019 Publication Archives of Dermatological Research Abbreviated Journal Arch Dermatol Res  
  Volume 311 Issue 7 Pages 573-576  
  Keywords Animals; mouse models; Skin; Human Health  
  Abstract (up) Artificial light at night (LAN) is a pervasive phenomenon in today's society, and the detrimental consequences of LAN exposure are becoming apparent. LAN is associated with the increased incidence of metabolic disorders, cancers, mood alterations, and immune dysfunction in mammals. Consequently, we examined the effects of dim LAN (DLAN) on wound healing. Female C57BL/6 mice were housed for 3 weeks in DLAN or LD conditions prior to wounding. Following wounding, mice were maintained in either their previous light conditions or switched to the opposite lighting conditions for 3 weeks. DLAN prior to wounding impaired healing; specifically, mice in DLAN/DLAN had significantly larger wounds on day 8. Additionally, mice in DLAN/LD had significantly larger wounds on days 5, 7, 8, and 9, and increased average time to closure. These data demonstrate a potential harmful effect of DLAN on wound healing that should be considered and may represent a target for therapeutic intervention.

  Title The impact of the Jacques Cartier bridge illumination on the food chain: from insects to predators Type Journal Article
  Year 2019 Publication Community Ecology Abbreviated Journal Community Ecology  
  Volume 20 Issue 2 Pages 172-180  
  Keywords Animals; Ecology  
  Abstract (up) Artificial light at night can impact numerous diurnal species by influencing their distribution and habits. In this study, artificial lights placed on the Jacques Cartier bridge in Montreal, Canada were evaluated to determine their impact on insects, insectivorous birds and peregrine falcons. The impact was measured the year the illumination begun and the year following (two years in total). Insect distribution and abundance at three different sites around the bridge was measured. Insectivorous bird abundance and activity were evaluated by observing the cliff swallow as a proxy. Peregrine falcon presence and nesting behavior at the bridge was measured. Insects (aerial and aquatic) were found to be more abundant closer to the illuminated part of the bridge and particularly in the year following the illumination's beginning. Similarly, cliff swallows were more abundant at the bridge the year following the start of the illumination and their activity was more important closer to the illuminated section. Peregrine falcons were only present at the bridge in the year following the beginning of the illumination and specifically at the illuminated part of the bridge. No nesting was detected. These three groups are connected to each other through a food chain in which insect abundance impacts insectivorous bird abundance, which in turn impacts peregrine falcon presence. The illumination therefore positively impacts these three groups separately and together through their food chain. This research highlights the importance of monitoring bird and insect population close to the bridge and further continuation of these observations are necessary to determine if the observed tendency will continue to develop throughout the years.

  Title Using all-sky differential photometry to investigate how nocturnal clouds darken the night sky in rural areas Type Journal Article
  Year 2019 Publication Scientific Reports Abbreviated Journal Sci Rep  
  Volume 9 Issue 1 Pages 1391  
  Keywords Skyglow; differential photometry; clouds; sky brightness  
  Abstract (up) Artificial light at night has affected most of the natural nocturnal landscapes worldwide and the subsequent light pollution has diverse effects on flora, fauna and human well-being. To evaluate the environmental impacts of light pollution, it is crucial to understand both the natural and artificial components of light at night under all weather conditions. The night sky brightness for clear skies is relatively well understood and a reference point for a lower limit is defined. However, no such reference point exists for cloudy skies. While some studies have examined the brightening of the night sky by clouds in urban areas, the published data on the (natural) darkening by clouds is very sparse. Knowledge of reference points for the illumination of natural nocturnal environments however, is essential for experimental design and ecological modeling to assess the impacts of light pollution. Here we use differential all-sky photometry with a commercial digital camera to investigate how clouds darken sky brightness at two rural sites. The spatially resolved data enables us to identify and study the nearly unpolluted parts of the sky and to set an upper limit on ground illumination for overcast nights at sites without light pollution.
