  Title Light Pollution at Mount Wilson and at Palomar in 1931-32 Type Journal Article
  Year 2002 Publication The Observatory Abbreviated Journal  
  Volume 122 Issue Pages  
  Keywords Skyglow  
  Abstract I present a short summary of an unpublished letter by Joel Stebbins on light pollution at Mount Wilson Observatory and on Palmar Mountain in 1931-32. I analyzed his results and show that the light emission per capita in 1932 – o was about 3*1*10^17 photons s^-1 in the blue region, equivalent to about 220 lumens per head in the visual region. These my be compared with about 1*4*10^18 photons s^-1 in the blue region and about 1000 lumens per head in the visual region for California cities in 1970.

  Title Scotopic colour vision in nocturnal hawkmoths Type Journal Article
  Year 2002 Publication Nature Abbreviated Journal Nature  
  Volume 419 Issue 6910 Pages 922-925  
  Keywords Animals; Behavior, Animal; Color; Color Perception/*physiology; Conditioning (Psychology)/physiology; Cues; *Darkness; Discrimination Learning/physiology; Humans; Light; Lighting; Moths/*physiology; Photic Stimulation; Photoreceptor Cells, Invertebrate/physiology; Reward; Sensitivity and Specificity; Ultraviolet Rays  
  Abstract Humans are colour-blind at night, and it has been assumed that this is true of all animals. But colour vision is as useful for discriminating objects at night as it is during the day. Here we show, through behavioural experiments, that the nocturnal hawkmoth Deilephila elpenor uses colour vision to discriminate coloured stimuli at intensities corresponding to dim starlight (0.0001 cd x m(-2)). It can do this even if the illumination colour changes, thereby showing colour constancy-a property of true colour vision systems. In identical conditions humans are completely colour-blind. Our calculations show that the possession of three photoreceptor classes reduces the absolute sensitivity of the eye, which indicates that colour vision has a high ecological relevance in nocturnal moths. In addition, the photoreceptors of a single ommatidium absorb too few photons for reliable discrimination, indicating that spatial and/or temporal summation must occur for colour vision to be possible. Taken together, our results show that colour vision occurs at nocturnal intensities in a biologically relevant context.
