Title Catching insects while recording bats: impacts of light trapping on acoustic sampling Type Journal Article
Year 2018 Publication Remote Sensing in Ecology and Conservation Abbreviated Journal Remote Sens Ecol Conserv
Volume 4 Issue 3 Pages 240-247
Keywords Animals
Abstract Collecting information on bat prey availability usually involves the use of light traps to capture moths and flies that constitute the main prey items of most insectivorous bats. However, despite the recent awareness on the adverse effects of light on bats, little is known regarding the potential impacts of light trapping on the bat sampling outcomes when passive acoustic sampling and light trapping are implemented simultaneously. Using a before–after experimental design that involved the installation of a 6 W actinic light trap 1 m away from the bat detector, we tested the predictions that (1) slow‐flying bat species will be less active when the light trap is present, while the opposite will be true for fast‐flying species; and (2) bat species richness will be lower at lit conditions compared to dark ones. Our results suggest that the use of light traps in combination with bat detectors may considerably influence the outcomes of acoustic sampling. Although the activity of fast‐flying bat species did not differ between the two treatments, we found that the activity of slow‐flying ones such as Rhinolophus ferrumequinum and Rhinolophus hipposideros decreased significantly at lit conditions. Furthermore, we recorded fewer bat species when the light trap was deployed. To overcome this issue, we strongly recommend either (1) placing light traps at a considerable distance from bat detectors; or (2) using light traps during the night that follows the bat sampling if sampling needs to be at the same position; or (3) deploying non‐attractant insect traps such as Malaise traps if Lepidoptera is not the main order targeted.

Title Re-envisioning the Nocturnal Sublime: On the Ethics and Aesthetics of Nighttime Lighting Type Journal Article
Year 2018 Publication Topoi Abbreviated Journal
Volume In press Issue Pages
Keywords Society
Abstract Grounded in the practical problem of light pollution, this paper examines the aesthetic dimensions of urban and natural darkness, and its impact on how we perceive and evaluate nighttime lighting. It is argued that competing notions of the sublime, manifested through artificial illumination and the natural night sky respectively, reinforce a geographical dualism between cities and wilderness. To challenge this spatial differentiation, recent work in urban-focused environmental ethics, as well as environmental aesthetics, are utilized to envision the moral and aesthetic possibilities of a new urban nocturnal sublime. Through articulating the aspirations and constraints of a new urban nocturnal experience, this paper elucidates the axiological dimensions of light pollution, draws attention to nightscapes as a site of importance for urban-focused (environmental) philosophy, and examines the enduring relevance of the sublime for both the design of nighttime illumination and the appreciation of the night sky.

Title Optimization of Urban Street Lighting Conditions Focusing On Energy Saving, Safety and Users’ Needs Type Journal Article
Year 2018 Publication Contemporary Urban Affairs Abbreviated Journal
Volume 2 Issue 3 Pages 112-121
Keywords Lighting; Economics; Planning
Abstract The outdoor lighting constitutes a significant part of the night activities of people in contemporary cities. Nevertheless, in many cases, this may result in the increasing and irrational use of it affecting the users of public areas, the environment and driving safety. The subject of this paper is to extend the discussion on the subject, to provide answers and to suggest methods for the improvement of the existing conditions in urban street lighting through the use of new technologies and smart lighting management systems, with the aim of achieving a smooth relationship between the user’s needs, safety, sustainability, quality of life and energy saving.

Title Total An Investigation into Light Pollution as a Limiting factor for shift of Mass nesting ground at Rushikulya rookery Ganjam Odishas Type Journal Article
Year 2018 Publication American Journal of Marine Research and Reviews Abbreviated Journal
Volume 1 Issue 6 Pages
Keywords Animals
Abstract Illumination due to artificial lights on nesting beaches and from nearby place to nesting beaches is detrimental to sea turtles because it alters critical nocturnal behaviors specifically, their choice of nesting sites and their return path to the sea after nesting. Illuminations perplex the hatchlings to find sea after emerging. Numerous studies conducted in other countries have demonstrated that artificial lights negatively impact on turtles, both female adults as they come to and go from their home beach to lay eggs, and to turtle hatchlings as they seek out the way to the open ocean. In this study we correlated the mass nesting intensity of 5years (2012 to 2018) at Rushikulya mass nesting site to the illumination zone. Illumination due to light conditions on nesting beaches are complex, and measuring light pollution in a way that effectively captures the impacts to sea turtles is difficult. But increase in intensity of illumination on selective mass nesting beaches showed gradual reduction in intensity of preferred nesting site during the mass nesting event. A gradual shift of nesting preference was also observed more toward darker zone.

Title A Study on Sky Light Pollution based on Sky Glow in Jeju Island Type Journal Article
Year 2018 Publication Journal of the Architectural Institute of Korea Abbreviated Journal
Volume 34 Issue 4 Pages 83-91
Keywords Skyglow
Abstract Artificial lighting contributes greatly to developing civilizations. It allows daytime activities to continue throughout the dark hours of the day and thus increasing work productivity as well as allowing people to enjoy nighttime activities. In addition, artificial lighting is used to beautify landscapes, architectural monuments, and thus highlighting the social-economic development of a given place. However, excessive and improper usage of artificial lighting can lead to light pollution. Light pollution is a serious issue that is detrimental to human health. It has been linked to a number of health conditions including sleep disorder, visual discomfort as well as cancer. The effects of light pollution extend throughout the entire ecosystem, affecting both plants and animals. Furthermore, sky-glow from light pollution hinders astronomical observation. The current paper presents a study conducted on lit environment of a nightscape. The quality of the sky was measured in 144 spots using Sky Quality Meter (SQM) devices. The measured spots were chosen on the basis of land use as well as distance from the Halla Mountain.
