Title Amphibians' response to the lunar synodic cycle--a review of current knowledge, recommendations, and implications for conservation Type Journal Article
Year 2013 Publication Behavioral Ecology Abbreviated Journal Behavioral Ecology
Volume 24 Issue 1 Pages 53-62
Keywords amphibians; circular statistics; light; lunar cycle; moon phase; predator avoidance; reproductive synchronization; moonlight
Abstract The way in which amphibians respond to the geophysical changes brought about by the lunar synodic cycle is a neglected area of their ecology, but one which has recently generated interest. Knowledge of how amphibians respond to lunar phase is of intrinsic interest and also may be important for conservation and monitoring of populations. We surveyed the literature on amphibians’ responses to the lunar cycle and found 79 examples where moon phase in relation to amphibian behavior and ecology had been studied, across diverse amphibian taxa. Of the examples reviewed, most of them show some type of response to lunar phase, with only a few species being unaffected. We found that there is no significant difference between the numbers of species which increase, and those that decrease activity or reproductive behavior (including calling) during a full moon. The responses to the lunar cycle can not be generalized across taxonomic group, but instead are highly species specific and relate directly to the species’ ecology. The primary reasons for changes in amphibian behavior in response to the lunar cycle appear to be temporal synchronization of breeding and predator avoidance. Responses to changes in prey availability, facilitation of visual signalling and use of lunar cues in navigation and homing are less prevalent but merit further investigation. Comparisons between studies are hampered by differences in field and analytical methods; we therefore make a number of recommendations for future collection and analysis of data related to lunar phase.

Title Responses of insectivorous bats and nocturnal insects to local changes in street light technology Type Journal Article
Year 2019 Publication Austral Ecology Abbreviated Journal
Volume 44 Issue 6 Pages 1052-1064
Keywords Animals; Mammals; Bats; Chalinolobus gouldii; Miniopterus schreibersii oceanensis; Australia; LED; lighting; street lighting
Abstract Artificial light at night is a pervasive anthropogenic stressor for biodiversity. Many fast‐flying insectivorous bat species feed on insects that are attracted to light‐emitting ultraviolet radiation (10–400 nm). Several countries are currently focused on replacing mercury vapour lamps, which emit ultraviolet light, with more cost‐efficient light‐emitting diode (LED) lights, which emit less ultraviolet radiation. This reduction in ultraviolet light may cause declines in insect densities in cities, predatory fast‐flying bats, and some edge‐foraging and slow‐flying bats. Capitalising on a scheme to update streetlights from high ultraviolet mercury vapour to low ultraviolet LED in Sydney, Australia, we measured the activity of individual bat species, the activity of different functional groups and the bat and insect communities, before and after the change in technology. We also surveyed sites with already LED lights, sites with mercury vapour lights and unlit bushland remnants. Species adapted to foraging in cluttered vegetation, and some edge‐space foraging species, were more active in unlit bushland sites than in all lit sites and decreased in activity at lit sites after the change to LED lights. The change to LED streetlights caused a decrease in the fast‐flying Chalinolobus gouldii but not Miniopterus schreibersii oceanensis, the latter being more influenced by seasonal and environmental variables. Insect biomass was not affected by changing light types, but instead was negatively correlated with the moon's percentage illuminance. Changing streetlights to LEDs could result in a decline in some insectivorous bats in cities. This study confirms that unlit urban bushland remnants are important refuges for high bat diversity, particularly for more clutter‐adapted species and some edge‐space foraging species. Preventing light penetration into unlit bushland patches and corridors remains essential to protect the urban bat community.

Title Adaptive changes in sexual signalling in response to urbanization Type Journal Article
Year 2018 Publication Nature Ecology & Evolution Abbreviated Journal Nat Ecol Evol
Volume 3 Issue Pages 374-380
Keywords Animals
Abstract Urbanization can cause species to adjust their sexual displays, because the effectiveness of mating signals is influenced by environmental conditions. Despite many examples that show that mating signals in urban conditions differ from those in rural conditions, we do not know whether these differences provide a combined reproductive and survival benefit to the urban phenotype. Here we show that male tungara frogs have increased the conspicuousness of their calls, which is under strong sexual and natural selection by signal receivers, as an adaptive response to city life. The urban phenotype consequently attracts more females than the forest phenotype, while avoiding the costs that are imposed by eavesdropping bats and midges, which we show are rare in urban areas. Finally, we show in a translocation experiment that urban frogs can reduce risk of predation and parasitism when moved to the forest, but that forest frogs do not increase their sexual attractiveness when moved to the city. Our findings thus reveal that urbanization can rapidly drive adaptive signal change via changes in both natural and sexual selection pressures.

Title Arthropod phototaxis and its possible effect on bird strike risk at two Namibian airports Type Journal Article
Year 2015 Publication 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.
