  Title Artificial light at night erases positive interactions across trophic levels Type Journal Article
  Year 2020 Publication Functional Ecology Abbreviated Journal Funct Ecol  
  Volume 34 Issue 3 Pages 694-706  
  Keywords Ecology; artificial light at night; coastal assemblages; cyanobacteria; epilithic biofilm; herbivores; heterotrophic bacteria; positive effects  
  Abstract (up) 1. Artificial light at night (ALAN) is one of the most recently recognized sources of anthropogenic disturbance, with potentially severe effects on biological systems that are still to be fully explored. Among marine ecosystems, high‐shore habitats are those more likely to be impacted by ALAN, due to a more intense exposition to outdoor nocturnal lightings (mostly from lamps along coastal streets and promenades, or within harbours, ports and marinas).

2. By performing in situ nocturnal manipulations of a direct source of white LED light and presence of herbivores in a Mediterranean high‐shore habitat, we assessed the interactive effects of light pollution and grazing on two key functional components of the epilithic microbial community (the cyanobacteria, as the main photoautotrophic component, and the other bacteria, mainly dominated by heterotrophs) developing on rocky shores.

3. Results showed an unexpected increase in the diversity of epilithic bacterial biofilm at unlit sites in the presence of grazers, that was more evident on the other (mainly heterotrophic) bacterial component, when giving weight to more abundant families. This effect was likely related to the mechanical removal of dead cells through the grazing activity of consumers. ALAN significantly modified this scenario, by reducing the density of grazers and thus erasing their effects on bacteria, and by increasing the diversity of more abundant cyanobacterial families.

4. Overall, direct and indirect effects on ALAN resulted in a significant increase in the diversity of the photoautotrophic component and a decrease in the heterotrophic one, likely affecting key ecosystem functions acting on rocky shore habitats.

5. ALAN may represent a threat for natural systems through the annihilation of positive interactions across trophic levels, potentially impairing the relationship between biodiversity and functioning of ecosystems and interacting with other global and local stressors currently impinging on coastal areas.

  Title Modification of Mammalian Sexual Cycles Type Journal Article
  Year 1935 Publication Journal of Experimental Biology Abbreviated Journal  
  Volume 12 Issue Pages 315-320  
  Keywords Animals  
  Abstract (up) 1. Cases are given in which female ferrets, already coming into, or in, oestrus as the result of artificially increased lighting in winter and spring, underwent regression or were retarded in their activation by reduction of either intensity or duration of daily illumination.

2. In some cases activation was resumed when light time or intensity was increased again.

3. These results are taken to indicate that, in female ferrets, any inherent rhythm or cycle of sexual activity is modified either naturally or artificially by changes of the cycles of duration and intensity of the light to which they are exposed daily, and so made to correspond in phases with the seasons, or changed therefrom. The rising daily illumination in spring and the falling one in late summer and autumn probably accelerate and retard the sexual activity of the female ferret, or accelerate the onset of anoestrus in late summer and autumn.

4. The data on modification of sexual cycles or activity in ferrets, so far obtained, are consistent with these conclusions.

  Title Literature study: The effects of reduced public lighting on crime, fear of crime, and road safety Type Journal Article
  Year 2019 Publication west-vlaanderen Abbreviated Journal  
  Volume Issue Pages  
  Keywords Safety; Security; Psychology; Review  
  Abstract (up) 1. Introduction

1.1 Stating the problem: security versus climate and economic challenges

Public street lighting as a public service is often taken for granted. However, its impact on the nocturnal perception of public space should not be underestimated. It encourages people to get out, feel safe, and be safe. Indeed, Welsh and Farrington suggest that public lighting enhances social control, cohesion, and a feeling of community pride (Welsh & Farrington, 2008b). According to (Williams, 2008), this is due to the special meaning attached to the darkness of night in society. It is associated with changes in social norms and values, transgression, the release of social control, feasting, drinking, and pleasure. Meanwhile, the darkness of night generates unpredictability, uncertainty and, therefore, fear. Illuminating the night chases away these feelings; people feel reassured and safer (Schivelbusch, 1995).
