Title (up) Artificial Outdoor Nighttime Lights Associate with Altered Sleep Behavior in the American General Population Type Journal Article
Year 2016 Publication Sleep Abbreviated Journal Sleep
Volume 39 Issue 6 Pages 1311-1320
Keywords Human Health; Remote Sensing; Sleep
Abstract STUDY OBJECTIVES: Our study aims to explore the associations between outdoor nighttime lights (ONL) and sleep patterns in the human population. METHODS: Cross-sectional telephone study of a representative sample of the general US population age 18 y or older. 19,136 noninstitutionalized individuals (participation rate: 83.2%) were interviewed by telephone. The Sleep-EVAL expert system administered questions on life and sleeping habits; health; sleep, mental and organic disorders (Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition, Text Revision; International Classification of Sleep Disorders, Second Edition; International Classification of Diseases, 10(th) Edition). Individuals were geolocated by longitude and latitude. Outdoor nighttime light measurements were obtained from the Defense Meteorological Satellite Program's Operational Linescan System (DMSP/OLS), with nighttime passes taking place between 19:30 and 22:30 local time. Light data were correlated precisely to the geolocation of each participant of the general population sample. RESULTS: Living in areas with greater ONL was associated with delayed bedtime (P < 0.0001) and wake up time (P < 0.0001), shorter sleep duration (P < 0.01), and increased daytime sleepiness (P < 0.0001). Living in areas with greater ONL also increased the dissatisfaction with sleep quantity and quality (P < 0.0001) and the likelihood of having a diagnostic profile congruent with a circadian rhythm disorder (P < 0.0001). CONCLUSIONS: Although they improve the overall safety of people and traffic, nighttime lights in our streets and cities are clearly linked with modifications in human sleep behaviors and also impinge on the daytime functioning of individuals living in areas with greater ONL.

Title (up) Artificial skyglow disrupts celestial migration at night Type Journal Article
Year 2020 Publication Current Biology Abbreviated Journal Current Biology
Volume 30 Issue 12 Pages R696-R697
Keywords Animals; Skyglow
Abstract Our understanding of the ecological impacts of direct outdoor lighting has improved substantially over the last decade [1, 2, 3]. In contrast, the impacts of artificial skyglow — that is, artificial light that is scattered in the atmosphere and reflected back to the ground — have received comparatively little attention [4]. Artificial skyglow extends the influence of direct lighting out to hundreds of kilometres from direct sources (for example street lights). It is the most geographically widespread form of light pollution, affecting 23% of the world’s land surface (between 75°N and 60°S) [5]. Artificial skyglow illuminances are two orders of magnitude lower (0.2–0.5 lx) than light pollution from direct artificial light (typically 10–100 lx), but greater than moonlight (0.1–0.3 lx) and light from the Milky Way (0.001 lx). Numerous organisms from across the animal kingdom orient themselves during migrations using lunar compasses [6, 7, 8, 9], and are vulnerable to artificial skyglow across large (10–100 km) spatial scales. Here we demonstrate that artificial skyglow disrupts nightly migrations by the amphipod Talitrus saltator (commonly known as the sandhopper), which uses the sky position of the moon [9, 10] as a guide.

Title (up) Artisanal and Small-Scale Mining Sites in the Democratic Republic of the Congo Are Not Associated with Nighttime Light Emissions Type Journal Article
Year 2019 Publication J Abbreviated Journal J
Volume 2 Issue 2 Pages 152-161
Keywords Remote Sensing
Abstract Maintaining records of artisanal and small-scale mining sites in developing countries requires considerable effort, so it would be beneficial if Earth observation data from space could assist in the identifying and monitoring of such sites. Artificial light emissions are common at industrial-scale mining sites and have been associated with small-scale illegal mining in some contexts. Here, we examine whether known artisanal and small-scale mining sites in the Democratic Republic of the Congo (DRC) are associated with observations of night light emissions by the Visible Infrared Imaging Radiometer Suite Day/Night Band (DNB). Light emissions from the mining sites were not observed: the radiance observed from the sites was near zero and nearly identical to that observed for a set of randomly-chosen locations in the same region. While it is the case that DNB night lights’ products provide useful data in other resource extraction contexts, they do not appear to be useful for identifying artisanal mining sites in the DRC.

Title (up) Ascospore release in apple scab underlies infrared sensation Type Journal Article
Year 2017 Publication Fungal Biology Abbreviated Journal Fungal Biol
Volume 121 Issue 12 Pages 1054-1062
Keywords Plants
Abstract The agent of apple scab disease (Venturia inaequalis) is the most common pathogen in apple cultivation. Its ascospores are released in spring, mainly during daylight hours and triggered by rain events. To investigate the causes of diurnal rhythm of ascospore dissemination of the apple scab fungus ascospore releases were examined continuously with spore traps in the orchard and with laboratory assays. One of the spore traps was illuminated at night with different light sources in each year during 2011-2015. The laboratory assays were performed with different light sources with varying wavelengths and intensities. In field and laboratory conditions only light including infrared radiation stimulated ascospore release, but not with light in the visible spectrum only. Artificial illumination during night was correlated with an increase of up to 46 % of ascospores released overnight in the field. We proved that infrared radiation induces V. inaequalis to release its spores. This is the first report in which spore discharge could be stimulated during night under field conditions.

Title (up) Assessing Light Pollution in China Based on Nighttime Light Imagery Type Journal Article
Year 2017 Publication Remote Sensing Abbreviated Journal Remote Sensing
Volume 9 Issue 2 Pages 135
Keywords Remote Sensing
Abstract Rapid urbanization and economic development inevitably lead to light pollution, which has become a universal environmental issue. In order to reveal the spatiotemporal patterns and evolvement rules of light pollution in China, images from 1992 to 2012 were selected from the Defense Meteorological Satellite Program Operational Linescan System (DMSP/OLS) and systematically corrected to ensure consistency. Furthermore, we employed a linear regression trend method and nighttime light index method to demonstrate China’s light pollution characteristics across national, regional, and provincial scales, respectively. We found that: (1) China’s light pollution expanded significantly in provincial capital cities over the past 21 years and hot-spots of light pollution were located in the eastern coastal region. The Yangtze River Delta, Pearl River Delta, and Beijing–Tianjin–Hebei regions have formed light pollution stretch areas; (2) China’s light pollution was mainly focused in areas of north China (NC) and east China (EC), which, together, accounted for over 50% of the light pollution for the whole country. The fastest growth of light pollution was observed in northwest China (NWC), followed by southwest China (SWC). The growth rates of east China (EC), central China (CC), and northeast China (NEC) were stable, while those of north China (NC) and south China (SC) declined; (3) Light pollution at the provincial scale was mainly located in the Shandong, Guangdong, and Hebei provinces, whereas the fastest growth of light pollution was in Tibet and Hainan. However, light pollution levels in the developed provinces (Hong Kong, Macao, Shanghai, and Tianjin) were higher than those of the undeveloped provinces. Similarly, the light pollution heterogeneities of Taiwan, Beijing, and Shanghai were higher than those of undeveloped western provinces.
