  Title Shedding light on light: benefits of anthropogenic illumination to a nocturnally foraging shorebird Type Journal Article
  Year 2013 Publication The Journal of Animal Ecology Abbreviated Journal J Anim Ecol  
  Volume 82 Issue 2 Pages 478-485  
  Keywords Artificial light; Dmsp/Ols; foraging strategy; moonlight; shorebirds; birds; animals; foraging; Tringa totanus; common redshank  
  Abstract Intertidal habitats provide important feeding areas for migratory shorebirds. Anthropogenic developments along coasts can increase ambient light levels at night across adjacent inter-tidal zones. Here, we report the effects of elevated nocturnal light levels upon the foraging strategy of a migratory shorebird (common redshank Tringa totanus) overwintering on an industrialised estuary in Northern Europe. To monitor behaviour across the full intertidal area, individuals were located by day and night using VHF transmitters, and foraging behaviour was inferred from inbuilt posture sensors. Natural light was scored using moon-phase and cloud cover information and nocturnal artificial light levels were obtained using geo-referenced DMSP/OLS night-time satellite imagery at a 1-km resolution. Under high illumination levels, the commonest and apparently preferred foraging behaviour was sight-based. Conversely, birds feeding in areas with low levels of artificial light had an elevated foraging time and fed by touch, but switched to visual rather than tactile foraging behaviour on bright moonlit nights in the absence of cloud cover. Individuals occupying areas which were illuminated continuously by lighting from a large petrochemical complex invariably exhibited a visually based foraging behaviour independently of lunar phase and cloud cover. We show that ambient light levels affect the timing and distribution of foraging opportunities for redshank. We argue that light emitted from an industrial complex improved nocturnal visibility. This allowed sight-based foraging in place of tactile foraging, implying both a preference for sight-feeding and enhanced night-time foraging opportunities under these conditions. The study highlights the value of integrating remotely sensed data and telemetry techniques to assess the effect of anthropogenic change upon nocturnal behaviour and habitat use.

  Title Reconnecting with darkness: gloomy landscapes, lightless places Type Journal Article
  Year 2013 Publication Social & Cultural Geography Abbreviated Journal Social & Cultural Geography

  Abstract This paper investigates the effects and affects of darkness, a condition that is progressively becoming less familiar for those of us in the over-illuminated West. In countering the prevailing cultural understanding that darkness is a negative condition, I draw attention to other historical and cultural ways of positively valuing darkness. Subsequently, in drawing on two sites, a gloomy landscape at a dark sky park in South Scotland, and a tourist attraction in which a simulation of New York is experienced in a completely dark environment, I explore the multivalent qualities of darkness. In foregrounding the becoming of sensory experience in gloomy space, I highlight the mobilisation of alternative modes of visual perception in as well as the emergence of non-visual apprehensions, and suggest that the potentialities of darkness might foster progressive forms of conviviality, communication and imagination.

Cet article interroge les effets et les affects de l'obscurité, une condition qui devient de moins en moins courante pour ceux parmi nous dans l'occident sur-illuminé. Pour s'opposer à la compréhension culturelle dominante que l'obscurité est une condition négative, j'attire l'attention aux autres façons historiques et culturelles de faire valoir l'obscurité. Ensuite, en tirant de deux sites—l'un, un paysage sombre à un parc de ciel obscure dans l'Ecosse du Sud, et l'autre, une attraction touristique dans laquelleon a une expérience d'une simulation de New York dans un environnement complètement noirci—j'examine les qualités polyvalentes de l'obscurité. En mettant en premier plan l'émergence de l'expérience sensorielle dans l'espace sombre, je souligne la mobilisation des modes alternatives de la perception visuelle ainsi que l'émergence des appréhensions non-visuelles, et je suggère que les potentialités de l'obscurité puissent encourager des formes progressives de la convivialité, la communication, et l'imagination.

Este artículo explora los efectos y los afectos asociadosa la oscuridad, una condición que resulta cada vez menos familiar para aquellos de nosotros que vivimos en unOccidentehiperiluminado.A los fines de contrarrestar la perspectiva cultural predominante que le asigna a la oscuridad una valoración negativa, pretendo llamar la atención sobre otras formas históricas y culturales que le otorgan un valor positivo a la oscuridad. Luego exploro las cualidades polivalentesde la oscuridad mediante el estudio de dos sitios: el paisaje sombrío de un parque sin iluminación artificial en el sur de Escocia y una atracción turística en el que se simula la ciudad de Nueva York, experimentada en un ambiente completamente oscuro.A los fines de dar cuenta del desarrollo de experiencias sensoriales en espacios sombríos, destaco la movilización de modos alternativos de percepción visual así como también la emergencia de formas de aprehensión no visuales Además,sugiero que la oscuridad tiene el potencial para promoverformas de convivencia, comunicación e imaginación progresistas.

  Title The Gloomy City: Rethinking the Relationship between Light and Dark Type Journal Article
  Year 2013 Publication Urban Studies Abbreviated Journal  
  Volume 52 Issue 3 Pages 422-438  
  Keywords Society  
  Abstract Given geography’s neglect of illuminated and dark space, this paper explores the various qualities of darkness that have contributed to the experience of the city. In recent history, darkness has been conceptualised negatively, for instance, with the ‘dark side’ and the ‘forces of darkness’ conceived as the opposite of that which enlightens and illuminates. Perhaps such metaphors testify to earlier urban conditions in which perils of all sorts lurked in the nocturnal city and doors were closed when darkness fell. Yet modern illumination has transformed nocturnal urban experience, producing cityscapes of regulation, hierarchical selectiveness, consumption, fantasy and imagination. However, this article suggests that the more positive qualities of darkness have been overlooked: the potential for conviviality and intimacy to be fostered in the dark, the aesthetics and atmospherics of darkness and shadow, the possibilities for apprehending the world through other senses and the dismissal of the star-saturated sky.
