  Title Conflicts between touristic recreational activities and breeding shearwaters: short-term effect of artificial light and sound on chick weight Type Journal Article
  Year 2018 Publication European Journal of Wildlife Research Abbreviated Journal Eur J Wildl Res  
  Volume 64 Issue 2 Pages (up)  
  Keywords Animals; Society  
  Abstract Human disturbances are increasingly becoming a conservation concern for many populations of colonial seabirds. Colonially reproducing species are particularly vulnerable to localised disturbances because detrimental elements can simultaneously affect the entire population. Studies of petrels and shearwaters have shown that light pollution, in particular, can be harmful for both fledglings and adults, but little is known of the way such anthropogenic elements affect the quality of parental care at the nest. Chick provisioning in petrels and shearwaters occurs exclusively at night and is also negatively correlated with the amount of moonlight. We tested the hypothesis that high-intensity light and sound disturbances will disrupt nest attendance and thus affect weight gain in chicks but that the magnitude of such effects would be modulated by moonlight conditions. We measured the effect of two outdoor disco events on overnight weight gain in 26 chicks of Scopoli’s shearwaters (Calonectris diomedea) from a breeding colony on Linosa Island. The two disco events occurred under contrasting moonlight conditions (moonless vs moonlight). Chicks situated closer to the disturbance gained significantly less weight compared to conspecifics from nests further away but the effect was only evident on the moonless night.Our results suggest that light and sound disturbances can have a negative effect on parental care in C. diomedea but moonlight might moderate the bird’s perception and thus the magnitude of the disturbance. However, while occasional disturbances may impact short-term weight gain in C. diomedea chicks, such effects are not perceivable at fledging when measured as differences in the weight or the date at which they left the nest.

  Title Influence of artificially induced light pollution on the hormone system of two common fish species, perch and roach, in a rural habitat Type Journal Article
  Year 2018 Publication Conservation Physiology Abbreviated Journal  
  Volume 6 Issue 1 Pages (up)  
  Keywords Animals  
  Abstract Almost all life on earth has adapted to natural cycles of light and dark by evolving circadian and circannual rhythms to synchronize behavioural and physiological processes with the environment. Artificial light at night (ALAN) is suspected to interfere with these rhythms. In this study we examined the influence of ALAN on nocturnal melatonin and sex steroid blood concentrations and mRNA expression of gonadotropins in the pituitary of European perch (Perca fluviatilis) and roach (Rutilus rutilus). In a rural experimental setting, fish were held in net cages in drainage channels experiencing either additional ALAN of ~15 lx at the water surface or natural light conditions at half-moon. No differences in melatonin concentrations between ALAN and natural conditions were detected. However, blood concentration of sex steroids (17β-estradiol; 11-ketotestosterone) as well as mRNA expression of gonadotropins (luteinizing hormone, follicle stimulating hormone) was reduced in both fish species. We conclude that ALAN can disturb biological rhythms in fish in urban waters. However, impacts on melatonin rhythm might have been blurred by individual differences, sampling methods and moonlight. The effect of ALAN on biomarkers of reproduction suggests a photo-labile period around the onset of gonadogenesis, including the experimental period (August). Light pollution therefore has a great potential to influence crucial life history traits with unpredictable outcome for fish population dynamics.

  Title The Night-time Environment in French Mountain Areas. A Resource and a Transition Operator Towards Sustainability Type Journal Article
  Year 2018 Publication Revue de géographie alpine Abbreviated Journal rga  
  Volume 106 Issue 1 Pages (up)  
  Keywords Darkness; Society  
  Abstract This article presents our approach to construct the night-time environment (NE) as an interdisciplinary research subject. Understood within the framework of various French mountain areas, we show that the NE is highly indicative of different development trajectories. We analyse them by combining traditional social science research into territory with the ecosystem approaches of the experimental sciences. We show how the NE resource (NER) is transformed into an operator that facilitates the transition towards sustainability. By highlighting three of the NE’s specifications, this work lays the groundwork for a transdisciplinary approach.

  Title “You Know the Pyrenees by Day – Come See Them by Night...” Reflections on in visu Artialisation of Nocturnal Skyscapes in the Pyrenees Type Journal Article
  Year 2018 Publication Revue de géographie alpine Abbreviated Journal rga  
  Volume 106 Issue 1 Pages (up)  
  Keywords Society; Economics; Darkness  
  Abstract “Nocturnal skyscapes. You know the Pyrenees by day – come see them by night... ”: thus the title of an exhibition of photographs set up in 2012 by the Pays de Lourdes et des Vallées des Gaves (Hautes-Pyrénées département) to help raise public awareness about the project for the Pic du Midi International Dark Sky Reserve (IDSR), mainly among the local population and stakeholders in the areas concerned.

Although its evocative title might suggest otherwise, this is rather more than an exhibition on the iconic sites of the Pyrenees seen at night. What it seems to do is to bring out new landscapes that are not just “mountainscapes at night”, or simply night-time versions of landscapes seen by day.

The night skies that characterise these landscapes therefore represent an new category, they need to be considered in their entirety as conveying a meaning that encompasses all that is both construed and material in our relationships with landscape. As in many areas with similar projects either in place (North America, Europe) or emerging (the Cévennes and Mercantour national parks in France, for example), the creation of the Pic du Midi IDSR will have helped to bring a new kind of “landscape object” (Besse, 2009) into being in the Pyrenean region.
