  Title Predation on cicadas by an Australian Flying-fox Pteropus poliocephalus based on DNA evidence Type Journal Article
  Year 2018 Publication Australian Zoologist Abbreviated Journal Australian Zoologist  
  Volume in press Issue Pages  
  Keywords Animals  
  Abstract Historically, reports of insectivory in family Pteropodidae have largely been anecdotal and thought to be an incidental corollary of flying-foxes feeding on plant products. More recent direct observations of flying-foxes catching and consuming insects, as well as advances in techniques that increase our ability to detect dietary items, suggest that this behaviour may be deliberate and more common than previously thought. Usually, multiple insects are consumed, but it appears that flying-foxes hunt and eat them one at a time. However, we have collected and photographed oral ejecta pellets under trees with high flying-fox activity, some containing evidence of multiple masticated insects. Further genetic analysis proved that these pellets came from Grey-headed Flying-foxes Pteropus poliocephalus. We propose that flying-foxes use an array of insect feeding strategies, most likely in response to variation in insect abundance and activity, as well as abiotic factors such as light and temperature.

  Title Measuring Light Pollution with Fisheye Lens Imagery from A Moving Boat–A Proof of Concept Type Journal Article
  Year 2017 Publication International Journal of Sustainable Lighting Abbreviated Journal  
  Volume 19 Issue 1 Pages 15-25  
  Keywords Skyglow; Instrumentation  
  Abstract Near all-sky imaging photometry was performed from a boat on the Gulf of Aqaba to measure the night sky brightness in a coastal environment. The boat was not anchored, and therefore drifted and rocked. The camera was mounted on a tripod without any inertia/motion stabilization. A commercial digital single lens reflex (DSLR) camera and fisheye lens were used with ISO setting of 6400, with the exposure time varied between 0.5 s and 5 s. We find that despite movement of the vessel the measurements produce quantitatively comparable results apart from saturation effects. We discuss the potential and limitations of this method for mapping light pollution in marine and freshwater systems. This work represents the proof of concept that all-sky photometry with a commercial DSLR camera is a viable tool to determine light pollution in an ecological context from a moving boat.

  Title Evaluation of pedestrian reassurance gained by higher illuminances in residential streets using the day–dark approach Type Journal Article
  Year 2018 Publication Lighting Research & Technology Abbreviated Journal Lighting Research & Technology  
  Volume in press Issue Pages  
  Keywords Vision; Psychology; Security  
  Abstract A field study was conducted to investigate how changes in the illuminance affect pedestrian reassurance when walking after dark in an urban location. The field study was conducted in daytime and after dark in order to employ the day–dark approach to analysis of optimal lighting. The results suggest that minimum illuminance is a better predictor of reassurance than is mean illuminance. For a day–dark difference of 0.5 units on a 6-point response scale, the results suggest a minimum horizontal illuminance of approximately 2.0 lux.

  Title Artificial light at night does not affect telomere shortening in a developing free-living songbird: A field experiment Type Journal Article
  Year 2019 Publication Science of The Total Environment Abbreviated Journal Science of The Total Environment  
  Volume 662 Issue Pages 266-275  
  Keywords Animals; birds; Great tit; Parus major; telomere shortening; Stress  
  Abstract Artificial light at night (ALAN) is an increasingly pervasive anthropogenic disturbance factor. ALAN can seriously disrupt physiological systems that follow circadian rhythms, and may be particularly influential early in life, when developmental trajectories are sensitive to stressful conditions. Using great tits (Parus major) as a model species, we experimentally examined how ALAN affects physiological stress in developing nestlings. We used a repeated-measure design to assess effects of ALAN on telomere shortening, body mass, tarsus length and body condition. Telomeres are repetitive nucleotide sequences that protect chromosomes from damage and malfunction. Early-life telomere shortening can be accelerated by environmental stressors, and has been linked to later-life declines in survival and reproduction. We also assayed nitric oxide, as an additional metric of physiological stress, and determined fledging success. Change in body condition between day 8 and 15 differed according to treatment. Nestlings exposed to ALAN displayed a trend towards a decline in condition, whereas control nestlings displayed a trend towards increased condition. This pattern was driven by a greater increase in tarsus length relative to mass in nestlings exposed to ALAN. Nestlings in poorer condition and nestlings that were smaller than their nest mates had shorter telomeres. However, exposure to ALAN was unrelated to telomere shortening, and also had no effect on nitric oxide concentrations or fledging success. Thus, exposure to ALAN may not have led to sufficient stress to induce telomere shortening. Indeed, plasticity in other physiological systems could allow nestlings to maintain telomere length despite moderate stress. Alternatively, the cascade of physiological and behavioral responses associated with light exposure may have no net effect on telomere dynamics.

  Title Insights into the impacts of three current environmental problems on Amphibians Type Journal Article
  Year 2018 Publication European Journal of Ecology Abbreviated Journal  
  Volume 4 Issue 2 Pages 15-27  
  Keywords Animals; Review  
  Abstract Global warming, light pollution and noise are common human-induced environmental problems that are escalating at a high rate. Their consequences on wildlife have mostly been overlooked, with the exception of a few species with respect to climate change. The problems often occur simultaneously and exert their negative effects together at the same time. In other words, their impacts are combined. Studies have never focused on more than one problem, and so, such combined effects have never been understood properly. The review addresses this lacuna in the case of amphibians, which are a highly vulnerable group. It divides the overall impacts of the problems into seven categories (behaviour, health, movement, distribution, phenology, development and reproductive success) and then assesses their combined impact through statistical analyses. It revealed that amphibian calling is the most vulnerable aspect to the combined impacts. This could provide important input for conservation of amphibians.
