  Title LOCALIZED LIGHT SENSORY IN RELATION TO GRAZING ACTIVITY OF ECHINOMETRA MATHAEI Type Journal Article
  Year 2018 Publication Abbreviated Journal  
  Volume Issue Pages  
  Keywords Animals  
  Abstract This paper offers insight on the regulation of nocturnal behavior in burrowing sea urchin Echinometra mathaei of the Pacific. While it is known E. mathaei maintains nocturnal hours of activity (primarily grazing, burrowing, and locomotion), it is unknown whether this pattern follows a circadian rhythm or responds to local conditions of darkness. Varying light treatments were tested to determine potential manipulation of active behavior and explore potential for habitat destruction. Light manipulation was used to determine the role light sensory plays in the regulation of normal behavior. First utilizing gradual manipulation and later utilizing sudden manipulation to differentiate response to light stimuli. It was determined that while E. mathaei maintains nocturnal

activity via localized light sensory, manipulation of latent hours could not be significantly reproduced. It was found that while light manipulation can be responsible for simulating hours of activity, light manipulation cannot replicate latent hours. Upon exploration of predator response capability in E. mathaei following manipulation, it was found that individuals exposed to prolonged periods of artificial light had slower predation response times than individuals acclimated to a regular pattern of light exposure. These findings connect potential habitat degradation via grazing behaviors of E. mathaei to anthropogenic activity in Mo’orea, French Polynesia.

  Title MOBILE MAPPING OF NIGHT-TIME ROAD ENVIRONMENT LIGHTING CONDITIONS Type Journal Article
  Year 2018 Publication The Photogrammetric Journal of Finland Abbreviated Journal  
  Volume 26 Issue 1 Pages  
  Keywords Lighting; Remote Sensing  
  Abstract The measurement of 3D geometry for road environments is one of the main applications of mobile mapping systems (MMS). We present mobile mapping applied to a night-time road environment. We integrate the measurement of luminances into a georeferenced 3D point cloud. The luminance measurement and the 3D point cloud acquired with an MMS are used in assessing road environment lighting conditions. Luminance (cd/m2) was measured with a luminance-calibrated panoramic camera system, and point cloud was produced by laser scanners. The relative orientation between the GNSS, IMU, camera, and laser scanner sensors was solved in order to

integrate the data sets into the same coordinate system. Hence, the georeferenced luminance values are transferable into geographic information systems (GIS). The method provides promising results for future road lighting assessment. In addition, this article demonstrates the night-time mobile mapping principle applied to a road section in Helsinki, Finland. Finally, we discuss the

future applications of mobile-mapped luminance point clouds.

  Title Low Levels of Artificial Light at Night Strengthen Top-Down Control in Insect Food Web Type Journal Article
  Year 2018 Publication Current Biology : CB Abbreviated Journal Curr Biol  
  Volume 28 Issue 15 Pages 2474-2478.e3  
  Keywords Ecology; Animals  
  Abstract Artificial light has transformed the nighttime environment of large areas of the earth, with 88% of Europe and almost 50% of the United States experiencing light-polluted night skies [1]. The consequences for ecosystems range from exposure to high light intensities in the vicinity of direct light sources to the very widespread but lower lighting levels further away [2]. While it is known that species exhibit a range of physiological and behavioral responses to artificial nighttime lighting [e.g., 3-5], there is a need to gain a mechanistic understanding of whole ecological community impacts [6, 7], especially to different light intensities. Using a mesocosm field experiment with insect communities, we determined the impact of intensities of artificial light ranging from 0.1 to 100 lux on different trophic levels and interactions between species. Strikingly, we found the strongest impact at low levels of artificial lighting (0.1 to 5 lux), which led to a 1.8 times overall reduction in aphid densities. Mechanistically, artificial light at night increased the efficiency of parasitoid wasps in attacking aphids, with twice the parasitism rate under low light levels compared to unlit controls. However, at higher light levels, parasitoid wasps spent longer away from the aphid host plants, diminishing this increased efficiency. Therefore, aphids reached higher densities under increased light intensity as compared to low levels of lighting, where they were limited by higher parasitoid efficiency. Our study highlights the importance of different intensities of artificial light in driving the strength of species interactions and ecosystem functions.

  Title Exploring spatiotemporal patterns of electric power consumption in countries along the Belt and Road Type Journal Article
  Year 2018 Publication Energy Abbreviated Journal Energy  
  Volume 150 Issue Pages 847-859  
  Keywords Remote Sensing  
  Abstract Fully understanding spatiotemporal patterns of electric power consumption (EPC) is one of the key questions related to sustainable socioeconomic and environmental development in countries along the Silk Road Economic Belt and the 21st-Century Maritime Silk Road (hereinafter referred to as the Belt and Road countries). However, studies about spatiotemporal patterns of EPC in the Belt and Road countries are still scarce due to the lack of reliable data. This study attempted to investigate spatiotemporal patterns of EPC in the Belt and Road countries from multiple perspectives. Firstly, the Defense Meteorological Satellite Program’s Operational Linescan System (DMSP-OLS) nighttime stable light data were used to estimate EPC from 1992 to 2013. Subsequently, the mathematical statistic method, standard deviational ellipse, rank size rule, and correlation analysis were employed to evaluate the EPC change in detail. The results reveal that the EPC growth mainly occurs in the developing countries, especially in China. The geographical distribution of EPC in the Belt and Road countries is oriented in the Northwest-Southeast direction between 1992 and 2013. Based on the rank size rule analysis, the slope values of q are −2.392 and −2.175 between 1992 and 2013, with an average R2 value of 0.664, indicating a clear clustering pattern of EPC. It is also proved that GDP is a more important impact factor to EPC than the population. Our findings can offer an effective way to understand spatiotemporal evolution characteristics of EPC in the Belt and Road countries, and provide references for regional socioeconomic development and cooperation.

  Title Modeling of Electric Demand for Sustainable Energy and Management in India Using Spatio-Temporal DMSP-OLS Night-Time Data Type Journal Article
  Year 2018 Publication Environmental Management Abbreviated Journal Environ Manage  
  Volume 61 Issue 4 Pages 615-623  
  Keywords Remote Sensing  
  Abstract Changes in the pattern of electric power consumption in India have influenced energy utilization processes and socio-economic development to greater extent during the last few decades. Assessment of spatial distribution of electricity consumption is, thus, essential for projecting availability of energy resource and planning its infrastructure. This paper makes an attempt to model the future electricity demand for sustainable energy and its management in India. The nighttime light database provides a good approximation of availability of energy. We utilized defense meteorological satellite program-operational line-scan system (DMSP-OLS) nighttime satellite data, electricity consumption (1993-2013), gross domestic product (GDP) and population growth to construct the model. We also attempted to examine the sensitiveness of electricity consumption to GDP and population growth. The results revealed that the calibrated DMSP and model has provided realistic information on the electric demand with respect to GDP and population, with a better accuracy of r (2) = 0.91. The electric demand was found to be more sensitive to GDP (r = 0.96) than population growth (r = 0.76) as envisaged through correlation analysis. Hence, the model proved to be useful tool in predicting electric demand for its sustainable use and management.
