  Title Social factors, not anthropogenic noise or artificial light, influence onset of dawn singing in a common songbird Type Journal Article
  Year 2019 Publication The Auk: Ornithological Advances Abbreviated Journal  
  Volume (up) Issue Pages  
  Keywords Animals  
  Abstract With worldwide increases in artificial light and anthropogenic noise, understanding how these pollutants influence animals allows us to better mitigate potential negative effects. Both light and noise affect the timing of daily activities, including the onset of dawn song in birds, yet the influence of these pollutants compared with social factors that also influence song onset remains unknown. We investigated the onset of dawn song, testing hypotheses aimed at understanding the influences of light and noise pollution as well as male competition, pairing status, and breeding stage on timing of dawn singing by male House Wrens (Troglodytes aedon). Overall, models with social factors fit song onset data better than models with abiotic factors of noise and sky glow, and the highest ranking model included nesting stage, number of male neighbors, and temperature. Males began singing earlier when they were building nests and when mates were fertile than during later nesting stages. Males also sang earlier as the number of male neighbors increased. The timing of dawn song by male House Wrens appeared unaffected by day-to-day variation in light and noise pollution, with social factors having larger effects on the onset of daily behavior in this species.

  Title A missing component of Arctic warming: Black carbon from gas flaring Type Journal Article
  Year 2019 Publication Environmental Research Letters Abbreviated Journal  
  Volume (up) Issue Pages  
  Keywords Remote Sensing  
  Abstract Gas flaring during oil extraction over the Arctic region is the primary source of warming-inducing aerosols (e.g., black carbon (BC)) with a strong potential to affect regional climate change. Despite continual BC emissions near the Arctic Ocean via gas flaring, the climatic impacts of BC related to gas flaring remain uncertain. Here, we present simulations of potential gas flaring using an earth system model with comprehensive aerosol physics that to show that increases in BC from gas flaring can potentially explain a significant fraction of Arctic warming. BC emissions from gas flaring over high latitudes contribute to locally confined warming over the source region, especially during the Arctic spring through BC-induced local albedo reduction. This local warming invokes remote and temporally lagging sea-ice melting feedback processes over the Arctic Ocean during winter. Our findings imply that a regional change in anthropogenic aerosol forcing is capable of changing Arctic temperatures in regions far from the aerosol source via time-lagged, sea-ice-related Arctic physical processes. We suggest that both energy consumption and production processes can increase Arctic warming.

  Title Comparative analysis of HPS and LED luminaries in terms of effectiveness of greenhouse plant lighting and light emission Type Journal Article
  Year 2019 Publication IEEE Xplore Abbreviated Journal  
  Volume (up) Issue Pages  
  Keywords Lighting; Light emitting diodes; LED; Lighting; Sodium; Electromagnetics; Light sources; Color; Production  
  Abstract The article focuses on the analysis of the parameters of light sources, spectrum characteristics of HPS and LED lighting to achieve the best results in greenhouse cultivation with the least energy consumption, and the escape of light into space. The authors have compared both sodium HPS and LED luminaries in the aspect of colour light efficiency and their influence on the plant vegetation process.

  Title Assessing Public Perceptions about Road Lighting in five Neighborhoods of Tirana, Albania Type Journal Article
  Year 2019 Publication Abbreviated Journal  
  Volume (up) Issue Pages  
  Keywords Public Safety; Psychology; Roadway lighting; Albania; Europe  
  Abstract Lighting is essential for sight, human health and well-being, emerging the need for assessing exterior lighting to better understand how far public is satisfied about exterior lighting. Exterior lighting was assessed in five major roads of the capital city of Tirana, Albania, in November 2017. Security, obstacle detection and visibility were evaluated using questionnaires for road lighting. The approximately 87 and 60 percent of respondents, respectively, were not able to detect a pavement obstacle after-dark and to distinguish a

familiar face at a distance of 5 m and 10 m along roads. Road lighting after-dark was unsatisfactory to 60 percent of respondents. These findings identified road lighting could be inadequate for users, requiring further investigation and new data collection of road lighting in neighborhoods of Tirana.

  Title LOCALIZED LIGHT SENSORY IN RELATION TO GRAZING ACTIVITY OF ECHINOMETRA MATHAEI Type Journal Article
  Year 2018 Publication Abbreviated Journal  
  Volume (up) 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.
