  Title Impacts of Artificial Light at Night on Biological Timings Type Journal Article
  Year 2017 Publication Annual Review of Ecology, Evolution, and Systematics Abbreviated Journal Annu. Rev. Ecol. Evol. Syst.  
  Volume 48 Issue 1 Pages 49-68  
  Keywords Animals; Plants; Review  
  Abstract The use of artificial lighting to illuminate the night has provided substantial benefits to humankind. It has also disrupted natural daily, seasonal, and lunar light cycles as experienced by a diversity of organisms, and hence it has also altered cues for the timings of many biological activities. Here we review the evidence for impacts of artificial nighttime lighting on these timings. Although the examples are scattered, concerning a wide variety of species and environments, the breadth of such impacts is compelling. Indeed, it seems reasonable to conclude that the vast majority of impacts of artificial nighttime lighting stem from effects on biological timings. This adds support to arguments that artificial nighttime lighting has a quite pervasive and marked impact on ecological systems, that the rapid expansion in the global extent of both direct illuminance and skyglow is thus of significant concern, and that a widespread implementation of mitigation measures is required.

  Title Effects of Artificial LED Light on the Growth of Three Submerged Macrophyte Species during the Low-Growth Winter Season: Implications for Macrophyte Restoration in Small Eutrophic Lakes Type Journal Article
  Year 2019 Publication Water Abbreviated Journal Water  
  Volume 11 Issue 7 Pages 1512  
  Keywords Plants  
  Abstract Eutrophication of lakes is becoming a global environmental problem, leading to, among other things, rapid reproduction of phytoplankton, increased turbidity, loss of submerged macrophytes, and the recovery of these plants following nutrient loading reduction is often delayed. Artificial light supplement could potentially be a useful method to help speeding up recovery. In this study, three common species of submerged macrophytes, Vallisneria natans, Myriophyllum spicatum and Ceratophyllum demersum, were exposed to three LED light treatments (blue, red and white) and shaded (control) for 100 days (from 10 November 2016 to 18 January 2017) in 12 tanks holding 800 L of water. All the three LED light treatments promoted growth of the three macrophyte species in terms of shoot number, length and dry mass. The three light treatments differed in their effects on the growth of the plants; generally, the red light had the strongest promoting effects, followed by blue and white. The differences in light effects may be caused by the different photosynthetic photon flux density (PPFD) of the lights, as indicated by an observed relationship of PPFD with the growth variables. The three species also responded differently to the light treatments, V. natans and C. demersum showing higher growth than M. spicatum. Our findings demonstrate that artificial light supplement in the low-growth winter season can promote growth and recovery of submerged macrophytes and hence potentially enhance their competitiveness against phytoplankton in the following spring. More studies, however, are needed to elucidate if LED light treatment is a potential restoration method in small lakes, when the growth of submerged macrophytes are delayed following a sufficiently large external nutrient loading reduction for a shift to a clear macrophyte state to have a potential to occur. Our results may also be of relevance when elucidating the role of artificial light from cities on the ecosystem functioning of lakes in urban areas.

  Title The Safe Distance Between Road Lighting Fixtures and Street Trees. Type Journal Article
  Year 2019 Publication Journal of Landscape Research Abbreviated Journal  
  Volume 11 Issue 2 Pages 41-43  
  Keywords Plants; Planning  
  Abstract The road lighting system and the road greening system, which are mutually interrelated and independent, are two important parts in the urban road environment Unreasonable road lighting is easy to induce light pollution and has a great negative impact on the physiology and growth of garden plants in the urban green space. In this paper; 21 kinds of common tree species in the urban green space of Zhengzhou were selected as the research object, and the photosynthetic physiological parameters of landscape trees under the TKD light source were observed using LI-6400 Photosynthesis System. This paper attempted to find the critical point for initiating photosynthesis of different types of tree species under a certain light source and then calculated the safe distance between lighting fixtures and landscape trees. The results showed that road lighting interfered with the photosynthetic physiological activities of the surveyed trees, affecting the normal dormancy of the plants at night; the sensitivity of different tree species to night lighting was different, and there were some differences in the light compensation points, so the corresponding safe distance was also different It is hoped that this study can provide a valuable reference and scientific basis for urban toad greening and lighting design.

  Title Urban park lighting as a source of botanical light pollution Type Journal Article
  Year 2019 Publication Photonics Letters of Poland Abbreviated Journal Photon.Lett.PL  
  Volume 11 Issue 3 Pages 90  
  Keywords Plants  
  Abstract That paper describesthe relative impact of anartificial lighting deviceon botanical light pollution, consideringspectral power distribution (SPD in the lighting area. This impact is described by the Relative-to-Moon Photosynthesis Index (RMPI)and Induced Phytochrome Index (IPr). We found that in the case when lighting is realized by using LED luminaires instead of high-pressure sodium (HPS) or metal halide (MH) lamps, the influence of spectral light on plant vegetation process amplifies. Additionally,our research shows that estimating botanical light pollution on the basis of lamps’CCT is not the best method and that using SPD is better for this purpose.

  Title Redesigning the exterior lighting as part of the urban landscape: The role of transgenic bioluminescent plants in mediterranean urban and suburban lighting environments Type Journal Article
  Year 2020 Publication Journal of Cleaner Production Abbreviated Journal Journal of Cleaner Production  
  Volume 242 Issue Pages 118477  
  Keywords Plants; Lighting  
  Abstract This research discusses the feasibility of replacing or supporting artificial lighting with Transgenic Bioluminescent Plants (TBP), as a means of minimizing light pollution, reducing electrical energy consumption and de-carbonizing urban and suburban outdoor environments, creating sustainable conditions and enriching the quality of life. Until now, no information is given about the light output of any TBPs and the question “Are the TBPs capable of producing the necessary lighting levels for exterior lighting?” is unanswered. For this reason, a new methodology is proposed for selecting and analyzing the lighting output potential of transgenic plants ted for specific climatic conditions. This methodology considers growth and reduction factors, as well as a formulae for estimating the plants’ luminous output by performing light measurements. Results show that transgenic plants in medium growth can emit a median luminous flux of up to 57 lm, a value that can definitely support low lighting requirements when used in large numbers of plants. From the lighting measurements and calculations performed in this research, the light output of the TBPs for a typical road with 5m width was found equal to 2lx. The amount of plants required was 40 at each side of the road for every 30m of streets with P6 road class. The results show that the use of bioluminescent plants can actually contribute to the reduction of energy consumption, concerning only the lighting criterium, thus creating an enormous opportunity for a new state-of- the-art market and research that could potentially minimize CO2 emissions and light pollution, improve urban and suburban microclimate, mitigate the effects of climate change, as well as provide an alternative means of lighting affecting both outdoor lighting design and landscape planning in suburban and urban settings. Moreover, further research should be applied considering also other possible ecological impacts before applying TBPs for exterior lighting applications.
