Title Dark sky tourism and the sustainability of regional tourism destinations Type Journal Article
Year 2020 Publication Tourism Recreation Research Abbreviated Journal Tourism Recreation Research
Volume 45 Issue 4 Pages 549-556
Keywords Skyglow; Dark sky tourism
Abstract Destinations across the globe face severe and potentially irreversible consequences from tourism growth and development. Contemporary approaches such as reducing access or site closures have been identified to increase demand, potentially exacerbating negative impacts. Despite acknowledgement of the impacts of tourism, limited studies have considered the ‘night sky’ as a tourism destination, nor the implications for regional sustainability. Consequently, the aim of this research is to explore the intersection between Dark sky tourism (DST) and sustainability within regional tourism. Semi-structured interviews were conducted in the Murweh Shire, in outback Australia. The analysis revealed sustainability, ethics and education as critical to achieving sustainable DST in a regional setting. A core contribution of this research is a conceptual model for sustainable DST. Future research is required to further explore ethics as a critical, yet often neglected, component of sustainable tourism.

Title Low impact of two LED colors on nocturnal insect abundance and bat activity in a peri‑urban environment Type Journal Article
Year 2020 Publication Journal of Insect Conservation Abbreviated Journal
Volume Issue Pages
Keywords Animals
Abstract Artifcial light at night (ALAN) is an important driver of change in ecological environments of the 21th century. We investigated the impact on nocturnal insect abundance and bat activity of two LED light colors (warm-white 2700 K, cold-white

6500 K) in a peri-urban environment. Bat activity (predominantly Pipistrellus pipistrellus) was largely driven by prey availability (insects), while insect abundance was responsive to nightly weather conditions (precipitation, temperature). Thus, both insects and bats were not diferentially responsive to cold-white or warm-white LEDs. These fndings are largely in contrast with literature, particularly for insects. However, as most published experiments on ALAN were conducted in areas that were lit solely for the purpose of the experiment, we would like to bring forward that (1) adaptation to environmental constraints may play a role in peri-urban environments that have been exposed to ALAN for many decades; or (2) impacts of cold-white LEDs on nocturnal insects may be lower than expected, because nocturnal insects adapted to low-light conditions may be put of by cold white light sources (6500 K).

Title Effects of traffic-regulated street lighting on nocturnal insect abundance and bat activity Type Journal Article
Year 2020 Publication Basic and Applied Ecology Abbreviated Journal Basic and Applied Ecology
Volume in press Issue Pages in press
Keywords Animals
Abstract New technological developments modulate the light levels of LED street luminaires according to traffic volumes: light levels are increased given traffic and reduced in its absence. Such dimming of street lights reduces the level of artificial light at night (ALAN) and may thus contribute to mitigate light pollution. To quantify the impact of traffic-driven dimming of street lights on nocturnal insect abundance and bat activity in comparison to full light (i.e., dimming functions of luminaires switched off), we mounted 20 insect flight-interception traps and ten batloggers on street light poles along two dimmable street light sections. Insect abundance and bat activity were measured alternately with one week of full street lighting followed by a week with light levels modulated by traffic volumes. In total, 16 dimmed and 16 full-light days were investigated. Overall, traffic-driven dimming reduced light levels by 35%. Weather conditions (warm, dry nights) were the main drivers of insect abundance and bat activity, but traffic-driven dimming resulted in lower numbers of insects caught and reduced bat activity. Among insect groups, Heteroptera benefited most from dimming. For bats, urban exploiters (Pipistrellus spp.) benefited from increased availability of prey at brightly lit street lights, while less frequent species (Myotis spp.) did not benefit from street lighting. We conclude that street light dimming technology may contribute to mitigate negative effects of ALAN on nocturnal organisms, although the measure may not be efficient enough to support light-sensitive and threatened species.

Title Patterns of wild carnivore attacks on humans in urban areas Type Journal Article
Year 2018 Publication Scientific Reports Abbreviated Journal Sci Rep
Volume 8 Issue 1 Pages
Keywords Animals
Abstract Attacks by wild carnivores on humans represent an increasing problem in urban areas across North America and their frequency is expected to rise following urban expansion towards carnivore habitats. Here, we analyzed records of carnivore attacks on humans in urban areas of the U.S. and Canada between 1980 and 2016 to analyze the general patterns of the attacks, as well as describe the landscape structure and, for those attacks occurring at night, the light conditions at the site of the attacks. We found that several behavioral and landscape-related factors were recurrent elements in the attacks recorded. The species for which the attack locations were available (coyote and black bear) attacked in areas with different conditions of landscape structure and artificial light. Specifically, black bears attacked more frequently in areas with abundant and aggregated vegetation cover and scarce buildings and roads, while coyotes attacked in a broader range of landscape conditions. At night, black bears attacked in generally darker areas than coyotes. By providing a comprehensive perspective of the phenomenon, this study will improve our understanding of how effective strategies aimed at reducing the frequency of risky encounters in urban areas should be developed.

Title Pollination and fruit infestation under artificial light at night:light colour matters Type Journal Article
Year 2020 Publication Scientific Reports Abbreviated Journal Sci Rep
Volume 10 Issue 1 Pages 18389
Keywords Plants; Ecology
Abstract Rapid human population growth and associated urbanization lead to increased artificial illumination of the environment. By changing the natural light-dark cycle, artificial lighting can affect the functioning of natural ecosystems. Many plants rely on insects in order to reproduce but these insects are known to be disturbed by artificial light. Therefore, plant-insect interactions may be affected when exposed to artificial illumination. These effects can potentially be reduced by using different light spectra than white light. We studied the effect of artificial lighting on plant-insect interactions in the Silene latifolia-Hadena bicruris system using a field set-up with four different light treatments: red, green, white and a dark control. We compared the proportion of fertilized flowers and fertilized ovules as well as the infestation of fruits by Hadena bicruris, a pollinating seed predator. We found no difference in the proportion of fertilized flowers among the treatments. The proportion of fruits infested by H. bicruris was however significantly higher under green and white light and a significantly lower proportion of fertilized ovules was found under green light. We show that artificial light with different colours impacts plant-insect interactions differently, with direct consequences for plant fitness.
