Title The influence of artificial light on stream and riparian ecosystems: questions, challenges, and perspectives Type Journal Article
Year 2011 Publication Ecosphere Abbreviated Journal Ecosphere
Volume 2 Issue 11 Pages art122
Keywords aquatic invertebrates; artificial illumination; ecosystems; fish; multiple stressors; riparian; streams; urbanization
Abstract Artificial light at night is gaining attention for its potential to alter ecosystems. Although terrestrial ecologists have observed that artificial light at night may disrupt migrations, feeding, and other important ecological functions, we know comparatively little about the role artificial light might play in disrupting freshwater and riparian ecosystems. We identify and discuss four future research domains that artificial light may influence in freshwater and associated terrestrial ecosystems, with an emphasis on running waters: (1) dispersal, (2) population genetics and evolution, (3) ecosystem functioning, and (4) potential interactions with other stressors. We suggest that future experimental and modeling studies should focus on the effects of different spectral emissions by different light sources on freshwater organisms, the spatial and temporal scale over which artificial light acts, and the magnitude of change in light at night across the landscape relative to the distribution of running and standing waters. Improved knowledge about the effects of artificial light on freshwater ecosystems will inform policy decisions about changes to artificial light spectral emissions and distributions.

Title How to reduce the impact of artificial lighting on moths: a case study on cultural heritage sites in Slovenia Type Journal Article
Year 2015 Publication Journal for Nature Conservation Abbreviated Journal J. for Nature Conservation
Volume 28 Issue Pages 105–111
Keywords Animals; Lighting; Ecology; ecological light pollution; moth diversity; flight-to-light; artificial illumination; Lepidoptera; Slovenis; Europe
Abstract In an ever more artificially illuminated world, common moth behaviour, flight-to-light, causes declines in their abundance and diversity that can have severe impacts on ecosystems. To test if it is possible to reduce the number of moths attracted to artificially illuminated objects, the original lighting of 15 cultural heritage buildings in Slovenia was substituted with blue or yellow lighting. These three illumination types differed in the amount of luminance, percentage of UV and short-wavelength light which are known to affect flight-to-light of moths. During our three-year field study approximately 20% of all known moth species in Slovenia were recorded. The blue and yellow illumination type attracted up to six times less specimens and up to four times less species compared to the original illumination type. This was true for all detected moths as well as within separate moth groups. This gives our study a high conservation value: usage of alternative, environmentally more acceptable illumination can greatly reduce the number of moths attracted to artificially illuminated objects.
