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 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 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 = −0.22). Species foraging on the surface of the water (piscivores and insectivores; r = −0.83) and forest canopy species (i.e., big frugivores; r = −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 Bright lights, big city: influences of ecological light pollution on reciprocal stream-riparian invertebrate fluxes Type Journal Article
Year 2013 Publication Ecological Applications Abbreviated Journal Ecological Applications
Volume 23 Issue 6 Pages 1322-1330
Keywords ecological light pollution; ecosystem function; stream–riparian invertebrate fluxes; tetragnathid spiders; urban streams
Abstract Cities produce considerable ecological light pollution (ELP), yet the effects of artificial night lighting on biological communities and ecosystem function have not been fully explored. From June 2010 to June 2011, we surveyed aquatic emergent insects, riparian arthropods entering the water, and riparian spiders of the family Tetragnathidae at nine stream reaches representing common ambient ELP levels of Columbus, Ohio, USA, streams (low, 0.1–0.5 lux; moderate, 0.6–2.0 lux; high, 2.1–4.0 lux). In August 2011, we experimentally increased light levels at the low- and moderate-treatment reaches to 10–12 lux to represent urban streams exposed to extremely high levels of ELP. Although season exerted the dominant influence on invertebrate fluxes over the course of the year, when analyzed by season, we found that light strongly influenced multiple invertebrate responses. The experimental light addition resulted in a 44% decrease in tetragnathid spider density (P = 0.035), decreases of 16% in family richness (P = 0.040) and 76% in mean body size (P = 0.022) of aquatic emergent insects, and a 309% increase in mean body size of terrestrial arthropods (P = 0.015). Our results provide evidence that artificial light sources can alter community structure and ecosystem function in streams via changes in reciprocal aquatic–terrestrial fluxes of invertebrates.

Title Fireflies and land use in an urban landscape: the case of Luciola italica L. (Coleoptera: Lampyridae) in the city of Turin Type Journal Article
Year 2013 Publication Journal of Insect Conservation Abbreviated Journal J Insect Conserv
Volume 17 Issue 4 Pages 797-805
Keywords Turin; insects; Coleoptera Lampyridae; Luciola italica; Urban environment; Fireflies; Light pollution; Ecological corridors; Green areas; Po River; Italy
Abstract Research was carried out in the city of Turin (Northern Italy) in order to assess the suitability of the urban environment for fireflies.The study started in 2007 with an artistic and scientific project promoted by Parco Arte Vivente (PAV—Park of living art). Citizens joining the project recorded 18 areas where they could observe fireflies, which were identified as Luciola italica L. (Coleoptera Lampyridae). All of the 18 areas recorded by citizens were then visited during the summer of 2009 and the abundance of L. italica was estimated using transects. In 12 sites the presence of the firefly was confirmed. The habitat structures of L. italica were woods interspersed with clearings in the urban districts in the hills, and parks along rivers in the lower and more populated part of the city. In sites where fireflies were observed, the level of illuminance measured was significantly lower than in areas where L. italica was absent. The analysis of the landscape around the study areas showed a negative correlation between the extent of urbanization and fireflies abundance. Survival of L. italica populations in the urban area of Turin is influenced by the extent of green areas and the level of artificial illumination. Parks lying among rivers preserve a level of darkness suitable for fireflies and are connected by woody strips growing along the banks of rivers, that probably function as ecological corridors.

Title Insect reactions to light and its applications to pest management Type Journal Article
Year 2013 Publication Applied Entomology and Zoology Abbreviated Journal Appl Entomol Zool
Volume 48 Issue 4 Pages 413-421
Keywords ultraviolet; light; Integrated pest management; Artificial lighting; Photoreception; Phototaxis; Light-emitting diode; *Lighting
Abstract Insects are able to see ultraviolet (UV) radiation. Nocturnal insects are often attracted to light sources that emit large amounts of UV radiation, and devices that exploit this behavior, such as light traps for forecasting pest outbreaks, and electric insect killers, have been developed. Some diurnal species are attracted to yellow; yellow pan traps are used for conducting surveys for pest outbreaks and yellow sticky plates are used for pest control. Lamps that give off yellow illumination have been used effectively to control the activity of nocturnal moths and thus reduce damage to fruit, vegetables, and flowers. Covering cultivation facilities with film that filters out near-UV radiation reduces the invasion of pests such as whiteflies and thrips into the facilities, thus reducing damage. Reflective material placed on cultivated land can control the approach of flying insects such as aphids. Future development and use of new light sources such as light-emitting diodes is anticipated for promoting integrated pest management.
