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 Dark Sky Parks – new impulse for nature tourism development in protected areas (National Park Muranska Planina, Slovakia) Type Journal Article
Year 2016 Publication e-Review of Tourism Research Abbreviated Journal eRTR
Volume 13 Issue 5/6 Pages 536-549
Keywords Society; tourism; astrotourism; sustainable tourism; dark sky parks
Abstract Dark Sky Parks are one of important measures to support nature tourism in the protected

areas. In this paper, we introduce the concept of astro-tourism on the model area of National Park Muranska Planina (Slovakia), which should lead to the establishment of Dark Sky Park and the implementation of measures focused on dark sky protection, i.e. the elimination of light pollution over model area. The concept includes the measurement of night sky brightness, the selection of suitable observational sites and lighting plan. It is very important from the view of ecology, e.g. by the protection of night animal species. On the other hand, these characteristics can be fully used in new tourism concept in that protected area.

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 A direct influence of moonlight intensity on changes in melatonin production by cultured pineal glands of the golden rabbitfish, Siganus guttatus Type Journal Article
Year 2006 Publication Journal of Pineal Research Abbreviated Journal J Pineal Res
Volume 40 Issue 3 Pages 236-241
Keywords Animals; Circadian Rhythm; *Light; Melatonin/biosynthesis/*secretion; *Moon; Organ Culture Techniques; Perciformes/*physiology; Pineal Gland/physiology/*radiation effects
Abstract Rabbitfish are a restricted lunar-synchronized spawner that spawns around a species-specific lunar phase. It is not known how the fish perceive changes in cues from the moon. One possible explanation is that rabbitfish utilize changes in moonlight intensity to establish synchrony. The purpose of the present study was to examine whether or not the pineal gland of the golden rabbitfish can directly perceive changes in moonlight intensity. Isolated pineal glands were statically cultured under natural or artificial light conditions and melatonin secreted into the culture medium was measured using a time-resolved fluoroimmunoassay. Under an artificial light/dark cycle, melatonin secretion significantly increased during the dark phase. Under continuous light conditions, melatonin secretion was suppressed, while culture under continuous dark conditions seemed to duplicate melatonin secretion corresponding to the light/dark cycle in which the fish were acclimated. When cultured pineal glands were kept under natural light conditions on the dates of the full and the new moon, small amounts of melatonin were secreted at night. Moreover, exposure of cultured pineal glands to artificial and natural light conditions resulted in a significant decrease of melatonin secretion within 2 hr. These results suggest that the isolated pineal gland of golden rabbitfish responds to environmental light cycles and that 'brightness' of the night moon has an influence on melatonin secretion from the isolated pineal gland.
