Title Re-envisioning the Nocturnal Sublime: On the Ethics and Aesthetics of Nighttime Lighting Type Journal Article
Year 2018 Publication (down) Topoi Abbreviated Journal
Volume In press Issue Pages
Keywords Society
Abstract Grounded in the practical problem of light pollution, this paper examines the aesthetic dimensions of urban and natural darkness, and its impact on how we perceive and evaluate nighttime lighting. It is argued that competing notions of the sublime, manifested through artificial illumination and the natural night sky respectively, reinforce a geographical dualism between cities and wilderness. To challenge this spatial differentiation, recent work in urban-focused environmental ethics, as well as environmental aesthetics, are utilized to envision the moral and aesthetic possibilities of a new urban nocturnal sublime. Through articulating the aspirations and constraints of a new urban nocturnal experience, this paper elucidates the axiological dimensions of light pollution, draws attention to nightscapes as a site of importance for urban-focused (environmental) philosophy, and examines the enduring relevance of the sublime for both the design of nighttime illumination and the appreciation of the night sky.

Title Artificial lights and seabirds: is light pollution a threat for the threatened Balearic petrels? Type Journal Article

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 Red light at night permits the nocturnal rise of melatonin production in horses Type Journal Article
Year 2019 Publication (down) The Veterinary Journal Abbreviated Journal The Veterinary Journal
Volume in press Issue Pages
Keywords Animals
Abstract Exposure to white light at night suppresses melatonin production, impacts circadian rhythms and contributes to ill-health in humans. Human interaction with horses frequently occurs at night. We tested the hypothesis that dim red light would not suppress the nightly rise in serum melatonin levels in horses. In a crossover design, six horses were maintained for consecutive 48 h periods under a Light:Red (LR) and a Light:Dark (LD) photo-schedule. Transitions from light (>200 lux, polychromatic white light) to red (5 lux, peak wavelength 625 nm) or dark (<0.5 lux), and vice versa, coincided with ambient sunset and sunrise times. Blood was collected at 2 h intervals for 24 h during each treatment via indwelling jugular catheters. Samples were harvested for serum and stored at −20 °C until assayed for melatonin by radioimmunoassay. Repeated measures two-way ANOVA and t-tests analysed for differences in LR and LD melatonin profiles and their circadian rhythm parameters.

No time x treatment interaction or effect of treatment on serum melatonin levels were demonstrated (P > 0.05). A robust main effect of time (P<0.0001) predominated, with melatonin levels rising at night under both treatments. Statistically significant differences were not observed when LR and LD were compared for circadian rhythm measures of night time peak, area under the curve (AUC), or for times of onset (evening rise), offset (morning decline), or peak duration. Low intensity red light at night did not impact the pattern of melatonin secretion in this study and is, therefore, unlikely to impact the physiology of circadian or seasonal regulation.
