  Title The Impact of Environmental Light Intensity on Experimental Tumor Growth Type Journal Article
  Year 2017 Publication (up) Anticancer Research Abbreviated Journal  
  Volume 37 Issue 9 Pages 4967-4971  
  Keywords Animals  
  Abstract Background/Aim: Cancer research requires for consistent models that minimize environmental variables. Within the typical laboratory animal housing facility, animals may be exposed to varying intensities of light as a result of cage type, cage position, light source, and other factors; however, studies evaluating the differential effect of light intensity during the light phase on tumor growth are lacking. Materials and Methods: The effect of cage face light intensity, as determined by cage rack position was evaluated with two tumor models using the C57Bl/6NHsd mouse and transplantable B16F10 melanoma cells or Lewis lung carcinoma (LLC) cells. Animals were housed in individually-ventilated cages placed at the top, middle, or bottom of the rack in a diagonal pattern so that the top cage was closest to the ceiling light source, and cage face light intensity was measured. Following a two-week acclimation period at the assigned cage position, animals were subcutaneously administered either 1.3×106 B16F10 melanoma cells or 2.5×105 Lewis lung carcinoma cells. Weights of excised tumors were measured following euthanasia 18 days (melanoma) or 21 days (LCC) after tumor cell administration. Results: Cage face light intensity was significantly different depending on the location of the cage, with cages closest to the light source have the greatest intensity. Mean tumor weights were significantly less (p<0.001 for melanoma; p&#8804;0.01 for LCC) in middle light intensity mice compared to high and low light intensity mice. Conclusion: The environmental light intensity to which experimental animals are exposed may vary markedly with cage location and can significantly influence experimental tumor growth, thus supporting the idea that light intensity should be controlled as an experimental variable for animals used in cancer research.

  Title Artificial illumination reduces bait-take by small rainforest mammals Type Journal Article
  Year 2010 Publication (up) Applied Animal Behaviour Science Abbreviated Journal  
  Volume 127 Issue 1-2 Pages 66-72  
  Keywords animals; field experiment; predation risk  
  Abstract Small mammals often moderate their foraging behaviour in response to cues indicating a high local predation risk. We assessed the ability of cues associated with a high predation risk to reduce the consumption of bait by non-target small mammal species in a tropical rainforest, without inhibiting bait-take by feral pigs (Sus scrofa). The illumination of feeding stations with a low power light source caused small mammals to reduce their foraging intensity on sunflower seeds mixed through sand by 25% (P< 0.001) and on unprocessed corn-based feral pig bait by 80% (P< 0.001). Illumination also reduced the intensity with which small mammals fed on commercially manufactured baits (odds ratio. = 6.17, P= 0.009). Illumination did not cause pigs to reduce their intake of corn bait (P= 0.43). Neither pig nor dingo (Canis lupus dingo) vocalisations had any detectable effect on the foraging intensity of small mammals (P> 0.05 for all treatments). We conclude that site illumination was an effective method of selectively deterring small mammals from consuming feral pig baits in our study region, but had no effect on consumption of those baits by pigs.

  Title Nocturnal illumination and night flying insects Type Journal Article
  Year 2004 Publication (up) APPLIED ECOLOGY AND ENVIRONMENTAL RESEARCH Abbreviated Journal  
  Volume 2 Issue 1 Pages 17–52  
  Keywords Animals; light-trap; collecting distance; Babinet-point; moon phases  
  Abstract The present study discusses the light trapping of insects depending on the environmental illumination, twilight polarization phenomena and the moon phases. The trapping data were taken of Hungarian national light-trap network. The important results are the followings: The Babinet-point, a polarization free spot of the sky at twilight, can be a role of orientation of insects. The height of the Moon above

the horizon is in negative correlation with the number of the caught insects. The maximum individual

number of species was collected at various moon phases.

  Title Arthropod phototaxis and its possible effect on bird strike risk at two Namibian airports Type Journal Article
  Year 2015 Publication (up) Applied Ecology and Environmental Research Abbreviated Journal Appl. Ecol. & Environ. Res.  
  Volume 13 Issue 4 Pages 957-965  
  Keywords Animals; airport; arthropods; birds; bird strike; phototaxis; Lepidoptera; Namibia  
  Abstract Aircraft wildlife collisions are a global safety and financial problem for the aviation industry, with birds being the main concern. In Namibia, 97% of collisions at Namibia’s two main airports are reported to be with insectivorous birds. Phototaxis was identified as a major attractant to insectivorous

birds, which feed on the arthropods attracted to airport apron and terminal lights. This study considered the effect of light as an attraction at the rurally situated Hosea Kutako International and urban Eros airports. It further investigated the attractiveness of light colour (or wavelength) on arthropod abundance, biomass and diversity. The study found that phototaxis was a significant factor at Hosea Kutako only, and that white light was the main attractant for arthropods, specifically for large moths (Order Lepidoptera),

while yellow and orange light attracted significantly less arthropods. The study indicates a high likelihood that the Hosea Kutako apron lights (white) are an important attractant for arthropods, and therefore indirectly insectivorous birds, which can be reduced by replacing them with orange or yellow filters.
