Title Fireflies and land use in an urban landscape: the case of Luciola italica L. (Coleoptera: Lampyridae) in the city of Turin Type Journal Article
Year 2013 Publication Journal of Insect Conservation Abbreviated Journal J Insect Conserv
Volume 17 Issue 4 Pages 797-805
Keywords Turin; insects; Coleoptera Lampyridae; Luciola italica; Urban environment; Fireflies; Light pollution; Ecological corridors; Green areas; Po River; Italy
Abstract Research was carried out in the city of Turin (Northern Italy) in order to assess the suitability of the urban environment for fireflies.The study started in 2007 with an artistic and scientific project promoted by Parco Arte Vivente (PAV—Park of living art). Citizens joining the project recorded 18 areas where they could observe fireflies, which were identified as Luciola italica L. (Coleoptera Lampyridae). All of the 18 areas recorded by citizens were then visited during the summer of 2009 and the abundance of L. italica was estimated using transects. In 12 sites the presence of the firefly was confirmed. The habitat structures of L. italica were woods interspersed with clearings in the urban districts in the hills, and parks along rivers in the lower and more populated part of the city. In sites where fireflies were observed, the level of illuminance measured was significantly lower than in areas where L. italica was absent. The analysis of the landscape around the study areas showed a negative correlation between the extent of urbanization and fireflies abundance. Survival of L. italica populations in the urban area of Turin is influenced by the extent of green areas and the level of artificial illumination. Parks lying among rivers preserve a level of darkness suitable for fireflies and are connected by woody strips growing along the banks of rivers, that probably function as ecological corridors.

Title Insect reactions to light and its applications to pest management Type Journal Article
Year 2013 Publication Applied Entomology and Zoology Abbreviated Journal Appl Entomol Zool
Volume 48 Issue 4 Pages 413-421
Keywords ultraviolet; light; Integrated pest management; Artificial lighting; Photoreception; Phototaxis; Light-emitting diode; *Lighting
Abstract Insects are able to see ultraviolet (UV) radiation. Nocturnal insects are often attracted to light sources that emit large amounts of UV radiation, and devices that exploit this behavior, such as light traps for forecasting pest outbreaks, and electric insect killers, have been developed. Some diurnal species are attracted to yellow; yellow pan traps are used for conducting surveys for pest outbreaks and yellow sticky plates are used for pest control. Lamps that give off yellow illumination have been used effectively to control the activity of nocturnal moths and thus reduce damage to fruit, vegetables, and flowers. Covering cultivation facilities with film that filters out near-UV radiation reduces the invasion of pests such as whiteflies and thrips into the facilities, thus reducing damage. Reflective material placed on cultivated land can control the approach of flying insects such as aphids. Future development and use of new light sources such as light-emitting diodes is anticipated for promoting integrated pest management.

Title “Astronomical Tourism”: The Astronomy and Dark Sky Program at Bryce Canyon National Park Type Journal Article
Year 2013 Publication Tourism Management Perspectives Abbreviated Journal Tourism Management Perspectives
Volume 7 Issue Pages 1-15
Keywords Astronomy-related tourism; National parks; Night sky darkness; astrotourism; dark skies
Abstract Astronomical tourism represents a less-studied segment of sustainable tourism, where a dark night sky is the underlying resource. This article evaluates an astronomical tourism program, in this case at a national park with dark skies for observing. Bryce Canyon National Park (BCNP) in the southwestern United States has a well-developed astronomy program to serve visitors. The program consists of solar viewing during the day, multimedia evening programs, and night-time star gazing with telescopes. Depending on the specific measure used, it appears that up to 10% of park visitors may be involved with the formal Astronomy and Dark Sky Program and/or more informal astronomy activities. BCNP appears well positioned to take advantage of the dark sky attributes of the park and to educate visitors about the importance of maintaining and/or increasing the darkness of night skies. Potential future developments in the program may serve to further increase the number of visitors to BCNP.

Title Light-to-Light: PV-Fed LED Lighting Systems Type Journal Article
Year 2013 Publication IEEE Transactions on Power Electronics Abbreviated Journal IEEE Trans. Power Electron.
Volume 28 Issue 8 Pages 4063-4073
Keywords light-to-light systems; outdoor lighting; lighting technology; LED; LED lighting; photovoltaics; PV
Abstract This paper discusses the principle of operation, dynamic modeling, and control design for light-to-light (LtL) systems, whose aim is to directly convert the sun irradiation into artificial light. The system discussed in this paper is composed by a photovoltaic (PV) panel, an LED array, a dc-dc converter dedicated to the maximum power point tracking of the PV panel and a dc-dc converter dedicated to drive the LEDs array. A system controller is also included, whose goal is to ensure the matching between the maximum available PV power and the LED power by means of a low-frequency LEDs dimming. An experimental design example is discussed to illustrate the functionalities of the LtL system.

Title Nighttime Lights Compositing Using the VIIRS Day-Night Band: Preliminary Results Type Journal Article
Year 2013 Publication Proceedings of the Asia-Pacific Advanced Network Abbreviated Journal APAN Proceedings
Volume 35 Issue Pages 70
Keywords remote sensing; light pollution; VIIRS; satellite; radiometry
Abstract Dramatically improved nighttime lights capabilities are presented by the launch of the National Polar-orbiting Partnership (NPP) Visible Infrared Imaging Radiometer Suite (VIIRS) Day Night Band (DNB) sensor. Building on 18 years of experience compositing nighttime data from the Defense Meteorological Satellite Program (DMSP) Operational Linescan System (OLS), NOAA’s NGDC Earth Observation Group has started adapting their algorithms to process these new data. The concept of compositing nighttime data comprises combining only high quality data components over a period of time to improve sensitivity and coverage. For this work, flag image are compiled to describe image quality. The flag categories include: daytime, twilight, stray light, lunar illuminance, noisy edge of scan data, clouds, and no data. High quality data is defined as not having any of these attributes present. Two methods of reprojection are necessary due to data collection characteristics. Custom algorithms have been created to terrain-correct and reproject all data to a common 15 arc second grid. Results of compositing over two time periods in 2012 are presented to demonstrate data quality and initial capabilities. These data can be downloaded at http://www.ngdc.noaa.gov/eog/viirs/downloadviirsntl.html.
