Title Artificial lights and seabirds: is light pollution a threat for the threatened Balearic petrels? Type Journal Article
Year 2015 Publication The Wilson Journal of Ornithologynithology Abbreviated Journal J. of Ornith.
Volume 156 Issue 4 Pages 893-902
Keywords Animals; birds; shearwater; Balearic shearwater; Puffinus mauretanicus; Scopoli's shearwater; Calonectris diomedea; European storm-petrel; Hydrobates pelagicus; Balearic Islands; Mediterranean; light pollution; biology; ecology; conservation
Abstract Petrels are among the most threatened group of birds. On top of facing predation by introduced mammals and incidental bycatch, these seabirds have to deal with an emerging threat, light pollution, which is increasing globally. Fledglings are disoriented and attracted to artificial lights in their maiden night flights from their nests to the sea. Once grounded, they are exposed to multiple threats leading to high mortality. We report on numbers of three petrel species (Balearic shearwater Puffinus mauretanicus, Scopoli's shearwater Calonectris diomedea, and European storm-petrel Hydrobates pelagicus) rescued on the Balearic Islands, Mediterranean Sea, in the period 1999-2013. We assessed the proportion of grounded fledglings in the population and colonies impact based on radiance levels measured from a nocturnal satellite image. We also calculated the radius of light pollution impact. At least 304 fledgling birds were found stranded due to attraction to artificial lights, fatally affecting 8.5 % of them. The proportion of grounded fledglings ranged between 0.13 and 0.56 % of the fledglings produced annually. The body mass of Balearic and Scopoli's shearwater fledglings decreased with rescue date. Light-induced mortality increased during the fledging period for Scopoli's shearwaters. Birds were rescued at a mean distance of 4833 m from the nearest colony, and between 30 and 47 % of colonies were exposed to light-polluted areas. Although impact seems to be low for all species, urban development and, consequently, the increase in light pollution in the proximity of the colonies should be taken into account to reduce as much as possible this emerging source of mortality.

Title Response of Migratory Sea Lampreys to Artificial Lighting in Portable Traps Type Journal Article
Year 2012 Publication North American Journal of Fisheries Management Abbreviated Journal North American Journal of Fisheries Management
Volume 32 Issue 3 Pages 563-572
Keywords lampreys; Petromyzon marinus
Abstract This study evaluated responses by migratory spawning-phase sea lampreys Petromyzon marinus to artificial trap lighting in the laboratory and field with the aim of improving trapping as a method of sea lamprey control in the Laurentian Great Lakes. We hypothesized that lighting would improve trap success by increasing the attraction to, entrance into, or retention within portable sea lamprey traps. The responses of migratory sea lampreys to nocturnal lighting were complex and situation dependent. In the laboratory, where two traps were placed side by side, more sea lampreys were caught in the lit trap than in the unlit trap (80% versus 20%), largely because of increased attraction to the lit trap (75% of trap funnel entries by sea lampreys were in lit traps). In the field, where two traps were set 9 m apart and located against a barrier to upstream movement, there was no consistent difference in the numbers of sea lampreys caught in lit versus unlit traps. We provide two hypotheses for the variability in response to trap lighting between the laboratory and field, but overall the inconsistency of sea lamprey response to trap lighting leads us to conclude that the benefits of implementing trap lighting for sea lamprey control are limited. Lighting traps may be beneficial in situations where lighting is implemented in conjunction with other trap modifications that attract sea lampreys to within close proximity of traps or when traps are operated in stream locations that already encounter high volumes of sea lampreys.

Title Street lighting disrupts the diel migratory pattern of wild Atlantic salmon, Salmo salar L., smolts leaving their natal stream Type Journal Article
Year 2012 Publication Aquaculture Abbreviated Journal Aquaculture
Volume 330-333 Issue Pages 74-81
Keywords Artificial light; Behaviour; Migration; Salmon; Smolt; Street lighting
Abstract The migratory timing and behaviour of wild Atlantic salmon smolts leaving their natal stream was determined using a passive integrated transponder (PIT) antennae system at a study site on a tributary of the River Itchen, England. Experiments compared the downstream migration of smolts under natural control conditions (2000–2006) with two years (2008 and 2009) when the main downstream exit of the study site was subject to street-lit conditions every alternate night (maximum light intensity measured at the stream surface = 14 lx). Migration of smolts under control conditions was significantly (p < 0.01, n = 170) correlated with sunset. By contrast, street lighting resulted in the timing of migration being random (p = 0.11, n = 7; p = 0.76, n = 34, respectively) with respect to time of day. Furthermore, migration of smolts was significantly (p = 0.01, n = 19) correlated with the time of sunset for fish migrating when the lamp had been off, but random (p = 0.36, n = 22) when the lamp had been on (2008 and 2009 data, combined). This alteration in migratory behaviour due to street lighting may impact fitness.

Title The effect of artificial light on male breeding-season behaviour in green frogs,Rana clamitans melanota Type Journal Article
Year 2006 Publication Canadian Journal of Zoology Abbreviated Journal Can. J. Zool.
Volume 84 Issue 10 Pages 1528-1532
Keywords animals; amphibians; frogs; green frogs; Rana clamitans melanota; Reproduction; reproductive strategies
Abstract Artificial night lighting (or ecological light pollution) is only now gaining attention as a source of long-term effects on the ecology of both diurnal and nocturnal animals. The limited data available clearly indicate that artificial light can affect physiology and behaviour of animals, leading to ecological consequences at the population, community, and ecosystem levels. Aquatic ecosystems may be particularly vulnerable to such effects, and nocturnally breeding animals such as frogs may be especially affected. To address this potential, we quantify the effects of artificial light on calling and movement behaviour in a rural population of male green frogs (Rana clamitans melanota (Rafinesque, 1820)) during the breeding season. When exposed to artificial light, frogs produced fewer advertisement calls and moved more frequently than under ambient light conditions. Results clearly demonstrate that male green frog behaviour is affected by the presence of artificial light in a manner that has the potential to reduce recruitment rates and thus affect population dynamics.

Title Effects of enhanced lighting on the behaviour of nocturnal frogs Type Journal Article
Year 1993 Publication Animal Behaviour Abbreviated Journal Animal Behaviour
Volume 45 Issue 5 Pages 893-899
Keywords animals; amphibians; frogs; grey treefrog; Hyla chrysoscelis; foraging; infrared
Abstract Biologists studying anuran amphibians usually assume that artificial, visible light does not affect the behaviour of nocturnal frogs. This assumption was tested in a laboratory experiment. The foraging behaviour of grey treefrogs, Hyla chrysoscelis, was compared under four lighting conditions: ambient light (equivalent to bright moonlight, 0·003 lx), red-filtered light (4·1 lx), low-intensity 'white' light (3·8 lx), and high-intensity 'white' light (12·0 lx). The treatments were chosen to correspond to standard methods of field observation of frog behaviour. The foraging behaviour of frogs in the four treatments was observed using infra-red light that was invisible to the frogs. The ability of the frogs to detect, and subsequently consume prey was significantly reduced under all of the enhanced light treatments relative to the ambient light treatment. Thus, the use of artificial light, within the visible spectrum of the frogs' eyes, can influence the outcome of nocturnal behavioural observations. These results lead to the recommendation that anuran biologists use infra-red or light amplification devices when changes in frogs' visual capabilities may influence the conclusions drawn from a study.
