  Title Artificial light at night affects brain plasticity and melatonin in birds Type Journal Article
  Year 2019 Publication Neuroscience Letters Abbreviated Journal Neurosci Lett  
  Volume in press Issue Pages 134639  
  Keywords Animals; Artificial Light At Night (ALAN); cell proliferation; circadian cycle; melatonin; neuronal densities; zebra finches (Taeniopygia guttata)  
  Abstract Artificial light at night (ALAN), which disrupts the daily cycle of light, has vast biological impacts on all organisms, and is also associated with several health problems. The few existing studies on neuronal plasticity and cognitive functions in mammals indicate that a disruption of the circadian cycle impairs learning and memory and suppresses neurogenesis. However, nothing is known about the effect of ALAN on neuronal plasticity in birds. To this end, zebra finches (Taeniopygia guttata) were exposed to ecologically relevant ALAN intensities (0.5, 1.5 and 5 lux), treated with BrdU to quantify cell proliferation in their ventricular zone (VZ), and compared to controls that were kept under dark nights. We found, in our diurnal birds, that ALAN significantly increased cell proliferation in the VZ. However, neuronal densities in two brain regions decreased under ALAN, suggesting neuronal death. In addition, ALAN suppressed nocturnal melatonin production in a dose-dependent manner, and might also increase body mass. Taken together, our findings add to the notion of the deleterious effect of ALAN.

  Title Research on the Influence of Weather Conditions on Urban Night Light Environment Type Journal Article
  Year 2019 Publication Sustainable Cities and Society Abbreviated Journal Sustainable Cities and Society  
  Volume 54 Issue Pages 101980  
  Keywords Skyglow; Weather; sky brightness; Urban  
  Abstract The increasingly serious urban light pollution has deepened the relevant research, and weather conditions indeed have great impact on the urban night light environment. Based on the SQM instrument, fish-eye camera and weather-related systems, this paper analyzes the changing law of night sky with time and weather. The brightness of the typical clear night sky changes regularly with time, and mainly includes five phases: rapid decline phase, slow decline phase, unstable decline phase, smooth phase, and rapid increase phase of sky brightness. In two phases of the smooth sky brightness, the average sky brightness in the high and low brightness phase respectively is 18.123 mag/arcsecond2 and 18.82 mag/arcsecond2, and about 15 times and 8 times higher than those of the natural night sky. This paper establishes the regression model of typical clear night sky brightness in rapid decline phase and rapid increase phase of sky brightness. The sky magnitude brightness in rainy weather is much lower than that in clear weather, the difference is about 3 mag/arcsecond2, the brightness can be reach 15.63 mag / arcsecond2; the average magnitude brightness in snowy days is about 0.17 mag/arcsecond2 higher than that in cloudy weather. There is a significant correlation among the air quality index, the ground illumination ratio of moon, the atmospheric visibility and the sky brightness. The deepened air pollution can also intensify light pollution, which can increase to 3 and 10 times higher than the night sky brightness under the moderate and severe air pollution. The lunar cycle has the least impact on light pollution in clear days, the sky brightness with the full moon is about 2 and 3 times higher than that without the moon.

  Title Assessing the effects of artificial light at night on biodiversity across latitude – Current knowledge gaps Type Journal Article
  Year 2019 Publication Global Ecology and Biogeography Abbreviated Journal Global Ecol Biogeogr  
  Volume in press Issue Pages geb.13037  
  Keywords Ecology; biodiversity; Review  
  Abstract Aim

Exposure to artificial light at night (ALAN) is a risk factor for organisms. Considering the spread and increasing intensity of night brightness across the globe, and the key role of light at all biological levels, alterations of ecosystems are expected. Yet, we cannot predict the severity of the effects of ALAN in several biomes because little information is available outside the temperate zone. We reviewed current knowledge and identified traits that could be targeted to fill this knowledge gap in order to contribute to the elaboration of a biogeographical framework for the study of ALAN at the global scale.

Location

Global.

Time period

Current and next decades.

Methods

We analysed the latitudinal variation in ALAN and focused on environmental factors that vary with latitude but that have been overlooked. We reviewed biological traits that exhibit latitudinal variation and depend on light and photoperiod and compiled information about the predicted changes in human demography and road networks across different world regions.

Results

Cloud cover amplifies ALAN far away from urbanized areas. Because of the higher frequency of overcast sky nights, exposure effects may be stronger both at high latitudes and across a large fraction of the intertropical zone, although at different times of the year. Intertropical biomes host the largest fraction of global biodiversity. Although currently they are not the most exposed to ALAN, their human populations are growing, and urbanized areas and road networks are expanding. Hence, ALAN could have strong ecological consequences, with cloud cover as an aggravating factor.

Perspectives

Knowledge gaps currently limit our ability to predict the effects of ALAN in different biomes. Therefore, it will be important to start investigating the consequences of this novel environmental factor across the globe, in order to develop a relevant theoretical framework.

  Title The influence of artificial night at night and polarized light on bird-building collisions Type Journal Article
  Year 2020 Publication Biological Conservation Abbreviated Journal Biological Conservation  
  Volume 241 Issue Pages 108358  
  Keywords Animals  
  Abstract Collisions with buildings annually kill up to 1 billion birds in the United States. Bird-building collisions primarily occur at glass surfaces: birds often fail to perceive glass as a barrier and appear to be attracted to artificial light emitted from windows. However, some aspects of avian vision are poorly understood, including how bird responses to different types of light influence building collisions. Some evidence suggests birds can detect polarized light, which may serve as a cue to assist with migration orientation and/or detect water bodies. Dark, reflective surfaces, including glass, reflect high degrees of polarized light, causing polarized light pollution (PLP). However, no studies have analyzed the relationship between bird collisions and PLP reflected from buildings. Additionally, while artificial light at night (ALAN) is frequently implicated as a major factor influencing bird-building collisions, few studies have analyzed this relationship. We investigated both types of light pollution—PLP and ALAN—and their association with bird collisions at 48 façades of 13 buildings in Minneapolis, Minnesota, USA. We found that the area of glass emitting ALAN was the most important factor influencing collisions, and that this effect of ALAN was independent of overall glass area; this result provides strong support for turning off lights at night to reduce bird-building collisions. Although we found no relationship between PLP and collisions, additional research is needed to better understand bird responses to polarized light. Fully understanding how different aspects of light influence bird-building collisions can inform conservation efforts to reduce this major threat to birds.

  Title Annual maps of global artificial impervious area (GAIA) between 1985 and 2018 Type Journal Article
  Year 2020 Publication Remote Sensing of Environment Abbreviated Journal Remote Sensing of Environment  
  Volume 236 Issue Pages in press  
  Keywords Remote Sensing  
  Abstract Artificial impervious areas are predominant indicators of human settlements. Timely, accurate, and frequent information on artificial impervious areas is critical to understanding the process of urbanization and land use/cover change, as well as of their impacts on the environment and biodiversity. Despite their importance, there still lack annual maps of high-resolution Global Artificial Impervious Areas (GAIA) with longer than 30-year records, due to the high demand of high performance computation and the lack of effective mapping algorithms. In this paper, we mapped annual GAIA from 1985 to 2018 using the full archive of 30-m resolution Landsat images on the Google Earth Engine platform. With ancillary datasets, including the nighttime light data and the Sentinel-1 Synthetic Aperture Radar data, we improved the performance of our previously developed algorithm in arid areas. We evaluated the GAIA data for 1985, 1990, 1995, 2000, 2005, 2010, and 2015, and the mean overall accuracy is higher than 90%. A cross-product comparison indicates the GAIA data are the only dataset spanning over 30 years. The temporal trend in GAIA agrees well with other datasets at the local, regional, and global scales. Our results indicate that the GAIA reached 797,076 km2 in 2018, which is 1.5 times more than that in 1990. China and the United States (US) rank among the top two in artificial impervious area, accounting for approximately 50% of the world's total in 2018. The artificial impervious area of China surpassed that of the US in 2015. By 2018, the remaining eight among the top ten countries are India, Russia, Brazil, France, Italy, Germany, Japan, and Canada.
