Title The effect of variation in moonlight on nocturnal song of a diurnal bird species Type Journal Article
Year 2020 Publication (up) Behavioral Ecology and Sociobiology Abbreviated Journal Behav Ecol Sociobiol
Volume 74 Issue 9 Pages in press
Keywords Animals; Moonlight
Abstract The lunar cycle is known to affect the behaviour of strictly nocturnal species, but for diurnal species that are periodically active during the night, this has been less investigated. Nocturnal bird song is relatively common in diurnal species, yet research on this behaviour accounts for little of the research on avian vocalisations. This is surprising given that diurnal species are adapted for bright environments and therefore may be particularly sensitive to change in the lunar cycles. We used automated bioacoustic recorders and automatic song detection software to measure nocturnal song rate in a diurnal bird where both sexes sing, the willie wagtail (Rhipidura leucophrys). We deployed recorders at eight locations across four naturally dark sites resulting in 457 h of nocturnal audio. We confirmed anecdotal evidence suggesting that willie wagtails are prolific nocturnal singers during the breeding season and demonstrate that while both male and females sing during the day, nocturnal song is largely sung by males. Moreover, we show that nocturnal song increased with lunar illumination, contrasting with previous research on other diurnal species that sing at night. Our data allow us to hypothesise possible functions for nocturnal song in this species, such as territory defence or mate attraction.

Title Light pollution affects space use and interaction of two small mammal species irrespective of personality Type Journal Article
Year 2019 Publication (up) BMC Ecology Abbreviated Journal BMC Ecol
Volume 19 Issue 1 Pages 26
Keywords Animals; Animal personality; Hirec; Interspecific interactions; Nighttime illumination; Outdoor enclosure; Rodents
Abstract BACKGROUND: Artificial light at night (ALAN) is one form of human-induced rapid environmental changes (HIREC) and is strongly interfering with natural dark-light cycles. Some personality types within a species might be better suited to cope with environmental change and therefore might be selected upon under ongoing urbanization. RESULTS: We used LED street lamps in a large outdoor enclosure to experimentally investigate the effects of ALAN on activity patterns, movement and interaction of individuals of two species, the bank vole (Myodes glareolus) and the striped field mouse (Apodemus agrarius). We analyzed effects combined with individual boldness score. Both species reduced their activity budget during daylight hours. While under natural light conditions home ranges were larger during daylight than during nighttime, this difference vanished under ALAN. Conspecifics showed reduced home range overlap, proximity and activity synchrony when subjected to nighttime illumination. Changes in movement patterns in reaction to ALAN were not associated with differences in boldness score of individuals. CONCLUSIONS: Our results suggest that light pollution can lead to changes in movement patterns and individual interactions in small mammals. This could lead to fitness consequences on the population level.

Title The impact of the Jacques Cartier bridge illumination on the food chain: from insects to predators Type Journal Article
Year 2019 Publication (up) Community Ecology Abbreviated Journal Community Ecology
Volume 20 Issue 2 Pages 172-180
Keywords Animals; Ecology
Abstract Artificial light at night can impact numerous diurnal species by influencing their distribution and habits. In this study, artificial lights placed on the Jacques Cartier bridge in Montreal, Canada were evaluated to determine their impact on insects, insectivorous birds and peregrine falcons. The impact was measured the year the illumination begun and the year following (two years in total). Insect distribution and abundance at three different sites around the bridge was measured. Insectivorous bird abundance and activity were evaluated by observing the cliff swallow as a proxy. Peregrine falcon presence and nesting behavior at the bridge was measured. Insects (aerial and aquatic) were found to be more abundant closer to the illuminated part of the bridge and particularly in the year following the illumination's beginning. Similarly, cliff swallows were more abundant at the bridge the year following the start of the illumination and their activity was more important closer to the illuminated section. Peregrine falcons were only present at the bridge in the year following the beginning of the illumination and specifically at the illuminated part of the bridge. No nesting was detected. These three groups are connected to each other through a food chain in which insect abundance impacts insectivorous bird abundance, which in turn impacts peregrine falcon presence. The illumination therefore positively impacts these three groups separately and together through their food chain. This research highlights the importance of monitoring bird and insect population close to the bridge and further continuation of these observations are necessary to determine if the observed tendency will continue to develop throughout the years.
