Title Stemming the Tide of Light Pollution Encroaching into Marine Protected Areas: Light pollution in marine protected areas Type Journal Article
Year 2015 Publication Conservation Letters Abbreviated Journal Conservation Lett.
Volume (down) 9 Issue 3 Pages 164–171
Keywords Animals; Anthropogenic disturbance; artificial light; marine ecosystems; marine protected areas; pollution
Abstract Many marine ecosystems are shaped by regimes of natural light guiding the behavior of their constituent species. As evidenced from terrestrial systems, the global introduction of nighttime lighting is likely influencing these behaviors, restructuring marine ecosystems, and compromising the services they provide. Yet the extent to which marine habitats are exposed to artificial light at night is unknown. We quantified nighttime artificial light across the world's network of marine protected areas (MPAs). Artificial light is widespread and increasing in a large percentage of MPAs. While increases are more common among MPAs associated with human activity, artificial light is encroaching into a large proportion of even those marine habitats protected with the strongest legislative designations. Given the current lack of statutory tools, we propose that allocating “Marine Dark Sky Park” status to MPAs will help incentivize responsible authorities to hold back the advance of artificial light.

Title Spiders and the electric light Type Journal Article
Year 1887 Publication Science Abbreviated Journal Science
Volume (down) 9 Issue 208 Pages 92
Keywords Ecology; artificial light at night; spiders; arachnids
Abstract Some disadvantage or evil appears to be attendant upon every invention, and the electric light is not an exception in this respect. In this city they have been placed in positions with a view of illuminating the buildings, notably the treasury, and a fine and striking effect is produced. At the same time, a species of spider has discovered that game is plentiful in their vicinity, and that he can ply his craft both day and night. In consequence, their webs are so thick and numerous that portions of the architectural ornamentation are no longer visible, and when torn down by the wind, or when they fall from decay, the refuse gives a dingy and dirty appearance to every thing it comes in contact with. Not only this, but these adventurers take possession of the portion of the ceiling of any room which receives the illumination. It would be of interest to know whether this spider is confined to a certain latitude, and at what seasons of the year our temperature we can indulge in our illumination.

Title Street lighting changes the composition of invertebrate communities Type Journal Article
Year 2012 Publication Biology Letters Abbreviated Journal
Volume (down) 8 Issue 5 Pages 764-767
Keywords Ecology; artificial light pollution; community composition; ground-dwelling invertebrates; high pressure sodium; street lights
Abstract Artificial lighting has been used to illuminate the nocturnal environment for centuries and continues to expand with urbanization and economic development. Yet, the potential ecological impact of the resultant light pollution has only recently emerged as a major cause for concern. While investigations have demonstrated that artificial lighting can influence organism behaviour, reproductive success and survivorship, none have addressed whether it is altering the composition of communities. We show, for the first time, that invertebrate community composition is affected by proximity to street lighting independently of the time of day. Five major invertebrate groups contributed to compositional differences, resulting in an increase in the number of predatory and scavenging individuals in brightly lit communities. Our results indicate that street lighting changes the environment at higher levels of biological organization than previously recognized, raising the potential that it can alter the structure and function of ecosystems.

Title Out of the Dark: Establishing a Large-Scale Field Experiment to Assess the Effects of Artificial Light at Night on Species and Food Webs Type Journal Article
Year 2015 Publication Sustainability Abbreviated Journal
Volume (down) 7 Issue 11 Pages 15593-15616
Keywords ALAN; artificial light at night; ecosystems; freshwater; light pollution; loss of the night; photometric characterization; riparian; Verlust der Nacht
Abstract Artificial light at night (ALAN) is one of the most obvious hallmarks of human presence in an ecosystem. The rapidly increasing use of artificial light has fundamentally transformed nightscapes throughout most of the globe, although little is known about how ALAN impacts the biodiversity and food webs of illuminated ecosystems. We developed a large-scale experimental infrastructure to study the effects of ALAN on a light-naïve, natural riparian (i.e., terrestrial-aquatic) ecosystem. Twelve street lights (20 m apart) arranged in three rows parallel to an agricultural drainage ditch were installed on each of two sites located in a grassland ecosystem in northern Germany. A range of biotic, abiotic, and photometric data are collected regularly to study the short- and long-term effects of ALAN on behavior, species interactions, physiology, and species composition of communities. Here we describe the infrastructure setup and data collection methods, and characterize the study area including photometric measurements. None of the measured parameters differed significantly between sites in the period before illumination. Results of one short-term experiment, carried out with one site illuminated and the other acting as a control, demonstrate the attraction of ALAN by the immense and immediate increase of insect catches at the lit street lights. The experimental setup provides a unique platform for carrying out interdisciplinary research on sustainable lighting.

Title Filtered Streetlights Attract Hatchling Marine Turtles Type Journal Article
Year 2006 Publication Chelonian Conservation and Biology Abbreviated Journal Chelonian Conservation and Biology
Volume (down) 5 Issue 2 Pages 255-261
Keywords Reptilia; Testudines; Cheloniidae; Loggerhead turtle; turtles; marine turtles; reptiles; Caretta caretta; Chelonia mydas; hatchlings; artificial lighting; light “trapping”; orientation; seafinding; Florida
Abstract On many nesting beaches, hatchling marine turtles are exposed to poled street lighting that disrupts their ability to crawl to the sea. Experiments were done to determine how hatchlings responded to street lighting transmitted through 2 filters that excluded the most disruptive wavelengths (those <&#8201;530 nm; those <&#8201;570 nm). Filtered lighting, however, also attracted the turtles though not as strongly as an unfiltered (high-pressure sodium vapor) lighting. Filtering is therefore of limited utility for light management, especially since other alternatives (such as lowering, shielding, or turning off unnecessary lighting; use of dimmer lights embedded in roadways) are more effective.
