  Title Re-envisioning the Nocturnal Sublime: On the Ethics and Aesthetics of Nighttime Lighting Type Journal Article
  Year 2018 Publication 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 nighttime lights and the “real” well-being of nations : “Measuring economic growth from outer space” and welfare from right here on Earth Type Journal Article
  Year 2018 Publication Journal of Economics and Political Economy Abbreviated Journal  
  Volume 5 Issue 2 Pages 209-218  
  Keywords Economics; Remote Sensing  
  Abstract GDP remains too much of an imprecise measure of the standard of living. There

is a need for either substitutes or complements. Nighttime lights are a reasonable indicator of the extent, scale, and intensity of socio-economic activities, but a poor measure of national welfare. However, if nighttime lights are understood to constitute externalities, then their effects can be used to adjust measured growth for welfare. From that angle, nighttime lights appear to exert sub-optimal positive externalities in developing countries, and supra-optimal negative externality in developed countries. This means that even if we assume equal growth rates in developing and developed countries, welfare is enhanced by increasing nighttime lights in developing countries and reduced by increasing nighttime lights in developed countries.

  Title Shifting daylength regimes associated with range shifts alter aphid-parasitoid community dynamics Type Journal Article
  Year 2018 Publication Ecology and Evolution Abbreviated Journal Ecol Evol  
  Volume 8 Issue 17 Pages 8761-8769  
  Keywords Animals; Ecology  
  Abstract With climate change leading to poleward range expansion of species, populations are exposed to new daylength regimes along latitudinal gradients. Daylength is a major factor affecting insect life cycles and activity patterns, so a range shift leading to new daylength regimes is likely to affect population dynamics and species interactions; however, the impact of daylength in isolation on ecological communities has not been studied so far. Here, we tested for the direct and indirect effects of two different daylengths on the dynamics of experimental multitrophic insect communities. We compared the community dynamics under “southern” summer conditions of 14.5-hr daylight to “northern” summer conditions of 22-hr daylight. We show that food web dynamics indeed respond to daylength with one aphid species (Acyrthosiphon pisum) reaching much lower population sizes at the northern daylength regime compared to under southern conditions. In contrast, in the same communities, another aphid species (Megoura viciae) reached higher population densities under northern conditions. This effect at the aphid level was driven by an indirect effect of daylength causing a change in competitive interaction strengths, with the different aphid species being more competitive at different daylength regimes. Additionally, increasing daylength also increased growth rates in M. viciae making it more competitive under summer long days. As such, the shift in daylength affected aphid population sizes by both direct and indirect effects, propagating through species interactions. However, contrary to expectations, parasitoids were not affected by daylength. Our results demonstrate that range expansion of whole communities due to climate change can indeed change interaction strengths between species within ecological communities with consequences for community dynamics. This study provides the first evidence of daylength affecting community dynamics, which could not be predicted from studying single species separately.

  Title Optimization of Urban Street Lighting Conditions Focusing On Energy Saving, Safety and Users’ Needs Type Journal Article
  Year 2018 Publication Contemporary Urban Affairs Abbreviated Journal  
  Volume 2 Issue 3 Pages 112-121  
  Keywords Lighting; Economics; Planning  
  Abstract The outdoor lighting constitutes a significant part of the night activities of people in contemporary cities. Nevertheless, in many cases, this may result in the increasing and irrational use of it affecting the users of public areas, the environment and driving safety. The subject of this paper is to extend the discussion on the subject, to provide answers and to suggest methods for the improvement of the existing conditions in urban street lighting through the use of new technologies and smart lighting management systems, with the aim of achieving a smooth relationship between the user’s needs, safety, sustainability, quality of life and energy saving.

  Title Investigation of fallout events in Hutton’s shearwaters (Puffinus huttoni) associated with artificial lighting Type Journal Article
  Year 2017 Publication Notornis Abbreviated Journal  
  Volume 64 Issue 4 Pages 181-191  
  Keywords Animals  
  Abstract The risk of disorientation by artificial lights and subsequent ‘fallout’ has become a widely recognised issue for nocturnal procellariiform species. Using data from community-based rescue campaigns and systematic research, we assessed the characteristics of fallout events observed in fledglings of the threatened New Zealand endemic Hutton’s shearwater (Puffinus huttoni) or Kaikōura tītī. Despite strong annual variation in observed fallout numbers, the proportion of annually produced fledglings collected as ‘fallout birds’ remained below 1% each year. Among those, more than 80% survived due to community rescue efforts. Fallout was found to increase significantly during new moon, while weather effects remained inconclusive. Most fallout occurred within brightly lit areas of Kaikōura township, particularly along its coastal roads. High light source densities and high wattage lights appeared to be influential in some areas but could only partly explain the spatial distribution of fallout at this small scale.
