Title Higher Catch Rates Around the Full Moon for Blue Marlin, Makaira Nigricans, in a Diurnal Trolling Fishery Type Journal Article
Year 2013 Publication Bulletin of Marine Science Abbreviated Journal Bms
Volume 89 Issue (down) 3 Pages 759-765
Keywords fish; blue marlin; Makaira nigricans; Moon; moonlight; Feeding Behavior
Abstract The relationship between lunar phase and catch rates of blue marlin, Makaira nigricans Lacépède, 1802, in a diurnal trolling fishery at Yonaguni Island, southwestern Japan, was investigated. The mean catch per unit effort of blue marlin to lunar day was expressed by a periodic regression and significantly increased around the full moon. The stomach content index also significantly increased around the full moon in small blue marlin (<200 cm lower jaw–fork length), indicating that diurnal feeding activities of blue marlin increased around the full moon, especially for smaller individuals. The diurnal feeding activity is thought to be influenced by the nighttime activities of blue marlin and/or prey movements.

Title Light pollution increases morbidity and mortality rate from different causes in female rats Type Journal Article
Year 2013 Publication Advances in Gerontology Abbreviated Journal Adv Gerontol
Volume 3 Issue (down) 3 Pages 180-188
Keywords light-at-night; spontaneous tumors; nontumor pathology epiphysis; rats; animals; mammals
Abstract The influence of different light regimes (constant light, LL; constant darkness, DD; standard light regime, LD, 12 hours light/12 hours darkness; and natural lighting of the northwest of Russia (NL) on non-tumor pathology revealed in the post-mortem examination of female rats has been studied. It was found that keeping 25-days-old animals under LL and NL conditions led to an increase in the number of infectious diseases and the substantially faster development of spontaneous tumors (2.9 and 3.3 diseases per one rat, respectively), variety of nontumor pathology found in dead rats, compared with the animals in standard (standard light) regime (1.72 diseases per one rat). Light deprivation (DD) led to a substantial reduction in the development of new growth, as well as nontumor and infectious diseases (1.06 diseases per one rat), compared to the same parameters in a standard light regime.

Title Lunar phobia in bats and its ecological correlates: A meta-analysis Type Journal Article
Year 2013 Publication Mammalian Biology – Zeitschrift für Säugetierkunde Abbreviated Journal Mammalian Biology – Zeitschrift für Säugetierkunde
Volume 78 Issue (down) 3 Pages 216-219
Keywords Chiroptera; Foraging activity; Foraging habitat; Latitude; Moonlight; mammals; bats; animals
Abstract Animals show several behavioral strategies to reduce predation risks. Presumably, moonlight avoidance is a strategy used by some nocturnal species to reduce the risk of predation. In bats, some research indicates that foraging activity is negatively correlated with moonlight intensity, a phenomenon better known as lunar phobia. However, the currently available evidence is contradictory because some bat species reduce their activity during nights with more moonlight while the opposite occurs in other species. We quantitatively evaluated the strength and direction of the relationship between moonlight intensity and bat activity using a meta-analysis. We also looked at some ecological correlates of lunar phobia in bats. Specifically, we examined foraging habitat and latitude as potential moderators of the size of the lunar phobia effect. Our results show that, regardless of the method used to evaluate bat activity, the overall relationship between moonlight intensity and bat activity is significant and negative (r = &#8722;0.22). Species foraging on the surface of the water (piscivores and insectivores; r = &#8722;0.83) and forest canopy species (i.e., big frugivores; r = &#8722;0.30) are more affected by moonlight than those with different foraging habitats (understory, subcanopy, open air). Latitude was positively correlated with lunar phobia (r = 0.023). The stronger lunar phobia for bats foraging on the water surface and in the forest canopy may suggest that the risk of predation is greater where moonlight penetrates more easily. The significant effect of latitude as a moderator of lunar phobia suggests that there is a weak geographic pattern, with this phobia slightly more common in tropical bats than in temperate species.

Title Navigational efficiency of nocturnal Myrmecia ants suffers at low light levels Type Journal Article
Year 2013 Publication PloS one Abbreviated Journal PLoS One
Volume 8 Issue (down) 3 Pages e58801
Keywords Adaptation, Biological/*physiology; Animals; Ants/*physiology; Australian Capital Territory; *Cues; Geographic Information Systems; Homing Behavior/*physiology; *Light; Locomotion/*physiology; Orientation/*physiology; insects
Abstract Insects face the challenge of navigating to specific goals in both bright sun-lit and dim-lit environments. Both diurnal and nocturnal insects use quite similar navigation strategies. This is despite the signal-to-noise ratio of the navigational cues being poor at low light conditions. To better understand the evolution of nocturnal life, we investigated the navigational efficiency of a nocturnal ant, Myrmecia pyriformis, at different light levels. Workers of M. pyriformis leave the nest individually in a narrow light-window in the evening twilight to forage on nest-specific Eucalyptus trees. The majority of foragers return to the nest in the morning twilight, while few attempt to return to the nest throughout the night. We found that as light levels dropped, ants paused for longer, walked more slowly, the success in finding the nest reduced and their paths became less straight. We found that in both bright and dark conditions ants relied predominantly on visual landmark information for navigation and that landmark guidance became less reliable at low light conditions. It is perhaps due to the poor navigational efficiency at low light levels that the majority of foragers restrict navigational tasks to the twilight periods, where sufficient navigational information is still available.

Title Adverse health effects of nighttime lighting: comments on American Medical Association policy statement Type Journal Article
Year 2013 Publication American Journal of Preventive Medicine Abbreviated Journal Am J Prev Med
Volume 45 Issue (down) 3 Pages 343-346
Keywords American Medical Association; Cell Cycle/physiology; Circadian Rhythm/*physiology; DNA Damage/physiology; *Health Policy; Humans; Lighting/*adverse effects; United States
Abstract The American Medical Association House of Delegates in June of 2012 adopted a policy statement on nighttime lighting and human health. This major policy statement summarizes the scientific evidence that nighttime electric light can disrupt circadian rhythms in humans and documents the rapidly advancing understanding from basic science of how disruption of circadian rhythmicity affects aspects of physiology with direct links to human health, such as cell cycle regulation, DNA damage response, and metabolism. The human evidence is also accumulating, with the strongest epidemiologic support for a link of circadian disruption from light at night to breast cancer. There are practical implications of the basic and epidemiologic science in the form of advancing lighting technologies that better accommodate human circadian rhythmicity.
