  Title Polarized light pollution: a new kind of ecological photopollution Type Journal Article
  Year 2009 Publication Frontiers in Ecology and the Environment Abbreviated Journal Frontiers in Ecology and the Environment  
  Volume 7 Issue 6 Pages 317-325  
  Keywords light pollution; polarization; polarized light pollution  
  Abstract The alteration of natural cycles of light and dark by artificial light sources has deleterious impacts on animals and ecosystems. Many animals can also exploit a unique characteristic of light – its direction of polarization –as a source of information. We introduce the term “polarized light pollution” (PLP) to focus attention on the ecological consequences of light that has been polarized through interaction with human-made objects. Unnatural polarized light sources can trigger maladaptive behaviors in polarization-sensitive taxa and alter ecological interactions. PLP is an increasingly common byproduct of human technology, and mitigating its effects through selective use of building materials is a realistic solution. Our understanding of how most species use polarization vision is limited, but the capacity of PLP to drastically increase mortality and reproductive failure in animal populations suggests that PLP should become a focus for conservation biologists and resource managers alike.

  Title Challenges for biomimetic night time sky polarization navigation Type Conference Article
  Year 2016 Publication Proceedings of the SPIE Abbreviated Journal Proc SPIE  
  Volume 9797 Issue Pages  
  Keywords Animals; detection of light; biology; polarization; navigation  
  Abstract Studies on some species of insects have shown them to use the polarization pattern cast by the moon in the night sky to control heading. Additional heading cues are of value to autonomous systems, since the earth’s magnetic field is not uniform, often not available and is substantially modified by local phenomena. In addition to the required low-light sensitivity of a night time polarization compass, additional complexities caused by the relative intensity of terrestrial sources must be overcome. We will show that the end result will tend to be a less reliable compass than the equivalent day time polarization device.

  Title Modelling and Optimization of Solar Light Trap For “Reducing and Controlling” The Pest Population Type Journal Article
  Year 2015 Publication International Journal of Engineering Technology, Management and Applied Sciences Abbreviated Journal Intl. J. of Engr. Tech., Man. & Appl. Sci.  
  Volume 3 Issue 4 Pages 224-234  
  Keywords Animals; insects; India; Madanapalli; Chittor; Andhra Pradesh; moonlight; polarization  
  Abstract Reducing and controlling the pest population using light traps is an age old practice in our crop sector. Though there are several models and designs are available but we would plan to develop something that could be solar powered trap with collecting net and not dependent on any other source like wind power, mechanical power, fuel & electricity. This device operates automatically, turning on the light during light fails i.e., 6 P.M and turns off before sunrises i.e., 6A.M. Most of the damage causing insects are active only during that time. Installing one light trap in an acre attracts at least more than 1000 adult pests for a day. The insects attract solar light trap model had been tested in our field crops like vegetables, paddy, and sugarcane, fruit crops like mango, pomegranate, guava, coconut and tea, coffee and jasmine crops across India. In this study we examine the relationship between the Lunar Phases and the efficiency of light traps in catching pests in the month of March and April at Madanapalli, Chittor, Andhra Pradesh. The lunar phase depending on the polarized moonlight and the relative catch follow the collecting distance. The collecting distance ranged and averaged in the phase angle divisions. The study demonstrated for the first time the effect of increasing polarized moonlight in the first and last quarter on the flying activity of pests. Catching quantity depend on the connection with the collecting distance when is the greatest of collection distance.
