Title Combined effects of nocturnal exposure to artificial light and habitat complexity on fish foraging Type Journal Article
Year 2019 Publication Science of The Total Environment Abbreviated Journal Science of The Total Environment
Volume 684 Issue Pages 14-22
Keywords (up) Animal; fishes; Perca fluviatilis; Gammarus fossarum; gammarids; aquatic ecosystems
Abstract Due to the widespread use of artificial light, freshwater ecosystems in urban areas at night are often subjected to light of intensities exceeding that of the moonlight. Nocturnal dim light could modify fish behaviour and benefit visual predators because of enhanced foraging success compared to dark nights. However, effects of nocturnal light could be mitigated by the presence of structured habitats providing refuges for prey. We tested in laboratory experiments whether nocturnal light of low intensity (2 lx) increases foraging efficiency of the Eurasian perch (Perca fluviatilis) on invertebrate prey (Gammarus fossarum). The tests were conducted at dusk and night under two light regimes: natural cycle with dark nights and disturbed cycle with artificially illuminated nights, in habitats differing in structural complexity: sand and woody debris. We found that nocturnal illumination significantly enhanced the consumption of gammarids by fish compared to dark nights. In addition, the perch was as effective predator in illuminated nights (2 lx) as at dusk (10 lx). Woody debris provided an effective refuge only in combination with undisturbed darkness, but not in illuminated nights. Our results suggest that nocturnal illumination in aquatic ecosystems may contribute to significant reductions in invertebrate population sizes through fish predation. The loss of darkness reduces the possibility of using shelters by invertebrates and hence the effects of elevated light levels at night could not be mitigated by an increased habitat complexity.

Title Bats and lighting — six years on Type Journal Article
Year 2012 Publication The London Naturalist Abbreviated Journal
Volume 91 Issue Pages 69-88
Keywords (up) Animals
Abstract Since my ‘Bats and lighting’ review (Fure 2006), there has been interesting comment

from a number of sources: bat workers, entomologists and those from ophthalmic fields;

lighting professionals from the UK and Europe; and natural light campaigners (CPRE

and the Campaign for Dark Skies, CfDS). There has also been an increase in studies,

reviews, publications and guidance.Topics range from bat ecology, bat physiology, bats v.

illumination and insects v. illumination, and as prey species, rendering the initial review

out of date. All beg for a swift and positive intervention to change the way that we light

the environment

Title Light Pollution Modifies the Expression of Daily Rhythms and Behavior Patterns in a Nocturnal Primate Type Journal Article
Year 2013 Publication PLoS ONE Abbreviated Journal
Volume 8 Issue 11 Pages e79250
Keywords (up) Animals
Abstract Among anthropogenic pressures, light pollution altering light/dark cycles and changing the nocturnal component of the environment constitutes a threat for biodiversity. Light pollution is widely spread across the world and continuously growing. However, despite the efforts realized to describe and understand the effects of artificial lighting on fauna, few studies have documented its consequences on biological rhythms, behavioral and physiological functions in nocturnal mammals. To determine the impacts of light pollution on nocturnal mammals an experimental study was conducted on a nocturnal primate, the grey mouse lemur Microcebus murinus. Male mouse lemurs (N = 8) were exposed 14 nights to moonlight treatment and then exposed 14 nights to light pollution treatment. For both treatments, chronobiological parameters related to locomotor activity and core temperature were recorded using telemetric transmitters. In addition, at the end of each treatment, the 14th night, nocturnal and feeding behaviors were explored using an infrared camera. Finally, throughout the study, body mass and daily caloric food intake were recorded. For the first time in a nocturnal primate, light pollution was demonstrated to modify daily rhythms of locomotor activity and core temperature especially through phase delays and increases in core temperature. Moreover, nocturnal activity and feeding behaviors patterns were modified negatively. This study suggests that light pollution induces daily desynchronization of biological rhythms and could lead to seasonal desynchronization with potential deleterious consequences for animals in terms of adaptation and anticipation of environmental changes.

Title Light-trap Catch of Harmful Microlepidoptera Species in Connection with Polarized Moonlight and Collecting Distance Type Journal Article
Year 2013 Publication Journal of Advanced Laboratory Research in Biology Abbreviated Journal
Volume 4 Issue 4 Pages 108-117
Keywords (up) Animals
Abstract The paper deals with light-trap catch of 25 Microlepidoptera species depending on the polarized moonlight and

collecting distance. The catching data were chosen from the 27 stations of the Hungarian National Light-trap Network and

from the years between 1959 and 1961. Relative catch values were calculated from the catching data per stations and

swarming. They are ranged and averaged in the phase angle divisions. The catching peak of ten species is in First Quarter,

another ten species have the peak in the First Quarter and Last one, and only in two cases the peak is in Last Quarter. Then

there is the maximum ratio of polarized moonlight. Catching peak of only three species is in connection with the collecting

distance when is the greatest of collection distance.

Keywords: Microlepidoptera, light-trap moon phases, polarized moonlight, catching distance.

Title Atlantic Puffins are Attracted to Coastal Communities in Eastern Newfoundland Type Journal Article
Year 2013 Publication Northeastern Naturalist Abbreviated Journal
Volume 20 Issue 4 Pages 624-630
Keywords (up) Animals
Abstract The Puffin Patrol is a volunteer-based group that rescues fledgling Fratercula arctica (Atlantic Puffin) stranded in coastal communities overlooking the Witless Bay Seabird Ecological Reserve in Newfoundland, Canada, which hosts the two largest Atlantic Puffin colonies in North America. We examine local environmental factors (visibility, moon phase) that may influence light attraction in Atlantic Puffins and explore the use of weight data and other information collected through this volunteer-based initiative to help monitor the health of this important population. In 2011, only 13 live Atlantic Puffins were captured despite nightly search efforts throughout the fledging period; this low capture rate was attributed to poor breeding success at the colony. In contrast, in 2012, 414 live fledgling puffins were captured and successfully released between 6 August and 5 September; 388 of these were banded and weighed prior to release. Capture rates on nights with poor visibility due to fog (26 fledglings per night) were similar to fogless nights (24 fledglings per night). Most live Atlantic Puffins were captured within a two-week period around the new moon. Fledglings weighed 248 ± 25 (SD) g, range = 160–315 g; weights significantly declined over the fledging period. In addition to the direct conservation benefits of saving grounded Atlantic Puffins, information collected through this volunteer-based initiative 1) provides insight on factors affecting Atlantic Puffins' attraction to coastal communities, 2) shows the importance of mitigating artificial light during the birds' fledging period within these developing communities, and 3) helps collect important demographic information without causing additional disturbance to the colonies.
