  Title Dark Sky Parks – new impulse for nature tourism development in protected areas (National Park Muranska Planina, Slovakia) Type Journal Article
  Year 2016 Publication e-Review of Tourism Research Abbreviated Journal eRTR  
  Volume 13 Issue 5/6 Pages 536-549  
  Keywords Society; tourism; astrotourism; sustainable tourism; dark sky parks  
  Abstract Dark Sky Parks are one of important measures to support nature tourism in the protected

areas. In this paper, we introduce the concept of astro-tourism on the model area of National Park Muranska Planina (Slovakia), which should lead to the establishment of Dark Sky Park and the implementation of measures focused on dark sky protection, i.e. the elimination of light pollution over model area. The concept includes the measurement of night sky brightness, the selection of suitable observational sites and lighting plan. It is very important from the view of ecology, e.g. by the protection of night animal species. On the other hand, these characteristics can be fully used in new tourism concept in that protected area.

  Title Light Pollution: Assessment of Sky Glow on two Dark Sky Regions of Portugal Type Journal Article
  Year 2016 Publication Journal of Toxicology and Environmental Health, Part A: Current Issues Abbreviated Journal J Toxicol Environm Health  
  Volume 79 Issue 7 Pages 307-319  
  Keywords Skyglow; Portugal; Peneda-Gerês National Park; Alqueva  
  Abstract Artificial light at night (ALAN), producing light pollution (LP), is not a matter restricted to astronomy anymore. Light is part of modern societies and, as a consequence, the natural cycle day–night (bright–dark) has been interrupted in a large segment of the global population. There is increasing evidence that exposure to certain types of light at night and beyond threshold levels may produce hazardous effects to humans and the environment. The concept of “dark skies reserves” is a step forward in order to preserve the night sky and a means of enhancing public awareness of the problem of spread of light pollution worldwide. The aim of this study was to assess the skyglow at two sites in Portugal, the Peneda-Gerês National Park (PNPG) and the region now known as Dark Sky Alqueva Reserve. The latter site was classified as a “Starlight Tourism Destination“ by the Starlight Foundation (the first in the world to achieve this classification) following a series of night sky measurements in situ described herein. The measurements at PNPG also contributed to the new set of regulations concerning light pollution at this national park. This study presents the first in situ systematic measurements of night sky brightness, showing that at the two sites the skies are mostly in levels 3 to 4 of the Bortle 9-level scale (with level 1 being the best achievable). The results indicate that the sources of light pollution and skyglow can be attributed predominantly to contamination from nearby urban regions.

  Title Effects of LED light quality on the growth, metabolism, and energy budgets of Haliotis discus discus Type Journal Article
  Year 2016 Publication Aquaculture Abbreviated Journal Aquaculture  
  Volume 453 Issue Pages 31-39  
  Keywords Animals; Abalone; LED; Metabolism; Energy budgets; Haliotis discus; Haliotis discus discus; Photobiology  
  Abstract In this study, a bioenergetics approach was used to examine the effects of different LED light qualities (red, orange, blue, green light, natural light and a dark setting) on the growth and survival of the abalone Haliotis discus discus, and its physiological response mechanism under different light qualities. The results suggest that under blue or green light, the survival rate, specific growth rate, food intake, and food conversion efficiency of H. d. discus were significantly lower than in those groups under red or orange light (P < 0.05). Under red or orange light, pepsin, amylase and cellulose activity was significantly higher than those in any other light quality group (P < 0.05), whereas lipase activity exhibited no significant difference among the light quality groups (P > 0.05). Under blue or green light, lactate dehydrogenase activity and lactic acid content were higher (P < 0.05), suggesting enhanced anaerobic metabolism. Under blue or green light, H. d. discus lost more energy via excretion, feces and respiration than was acquired from its food. Under red or orange light, H. d. discus acquired more energy from its food and lost less energy via excretion and feces; as a result, its assimilation efficiency (K1) and net growth efficiency (K2) were significantly higher than those of any other group (P < 0.05). Therefore, we suggest that red or orange light should be used as a light source for the aquaculture of H. d. discus.

  Title Night sky orientation with diurnal and nocturnal eyes: dim-light adaptations are critical when the moon is out of sight Type Journal Article
  Year 2016 Publication Animal Behaviour Abbreviated Journal Animal Behaviour  
  Volume 111 Issue Pages 127-146  
  Keywords Animals; dung beetle; insect; Milky Way; nocturnal adaptation; polarized moonlight; sky compass; straight-line orientation; vision; Scarabaeus; Scarabaeus lamarcki; Scarabaeus satyrus  
  Abstract The visual systems of many animals feature energetically costly specializations to enable them to function in dim light. It is often unclear, however, how large the behavioural benefit of these specializations is, because a direct comparison in a behaviourally relevant task between closely related day- and night-active species is not usually possible. Here we compared the orientation performance of diurnal and nocturnal species of dung beetles, Scarabaeus (Kheper) lamarcki and Scarabaeus satyrus, respectively, attempting to roll dung balls along straight paths both during the day and at night. Using video tracking, we quantified the straightness of paths and the repeatability of roll bearings as beetles exited a flat arena in their natural habitat or under controlled conditions indoors. Both species oriented equally well when either the moon or an artificial point light source was available, but when the view of the moon was blocked and only wide-field cues such as the lunar polarization pattern or the stars were available for orientation, nocturnal beetles were oriented substantially better. We found no evidence that ball-rolling speed changed with light level, which suggests little or no temporal summation in the visual system. Finally, we found that both diurnal and nocturnal beetles tended to choose bearings that led them towards a bright light source, but away from a dim one. Our results show that even diurnal insects, at least those with superposition eyes, could orient by the light of the moon, but that dim-light adaptations are needed for precise orientation when the moon is not visible.

  Title Sensitive physiological indicators for human visual comfort evaluation Type Journal Article
  Year 2016 Publication Lighting Research and Technology Abbreviated Journal Lighting Res. & Tech.  
  Volume 48 Issue 6 Pages 726-741  
  Keywords Human health; human vision; Melatonin  
  Abstract Three physiological factors (melatonin levels, tear mucus ferning quality and degree of asthenopia) were examined for their relationship to visual comfort. A lighting environment was created where the illuminance, illuminance uniformity and correlated colour temperature could be adjusted. A three-factor and three-level orthogonal experiment with 24 subjects was designed and carried out. The results indicated that the selected environmental factors had different impacts on the physiological factors. With the illuminance increasing, the melatonin level decreased significantly and the tear mucus ferning quality was improved. However, there is no general influence of illuminance uniformity and correlated colour temperature on the physiological parameters, only differential effects among the three levels were found.
