  Title Effects of urban nighttime light on the growth of Cinnamomum camphora Type Journal Article
  Year 2019 Publication Ying Yong Sheng Tai Xue Bao Abbreviated Journal  
  Volume 30 Issue (up) 7 Pages 2284-2290  
  Keywords Plants  
  Abstract To understand the effects of urban artificial nighttime light on the growth of evergreen trees, we conducted a field investigation in a typical urban street planted with Cinnamomum camphora (a common evergreen street tree species in eastern China) in the Nanjing City, China. Along the street, trees from two types of growing locations with contrasting distances from the street lamp (just under the lamp vs. between two adjacent lamps) were selected. The growth-related plant functional traits were measured and compared. The results showed that trees grown under the lamp had a mean diameter at beast height (DBH) of 16.8 cm, current-year branch productivity (CBP) of 309.4 g·m-2, current-year leaf productivity (CLP) of 241.5 g·m-2, and leaf relative chlorophyll content (LCC) of 34.6 SPAD. Trees grown between lamps had a mean DBH of 15.5 cm, CBP of 273.4 g·m-2, CLP of 212.8 g·m-2, and LCC of 33.1 SPAD. DBH, CBP, CLP and LCC of the trees under the lamp were significantly higher than those between lamps. There was no significant difference in specific leaf area between trees from the two locations. Our results suggested that urban artificial nighttime light could promote the growth of C. camphora, and alter sunlight-determined characteristics of canopy growth vigor.

为了解常绿乔木对城市夜间灯光的生长响应,以华东地区典型常绿行道树种香樟为对象,研究南京市一条典型道路上近灯处(路灯正下方)和远灯处(两相邻路灯中间位置)生长区位的夜间光照强度差异性对香樟生长性状的影响.结果表明: 近灯处香樟的平均胸径为16.8 cm,当年生小枝总生产力为309.4 g·m-2,当年生叶片生产力为241.5 g·m-2,叶片相对叶绿素含量为34.6 SPAD.远灯处香樟的平均胸径为15.5 cm,当年生小枝总生产力为273.4 g·m-2,当年生叶片生产力为212.8 g·m-2,叶片相对叶绿素含量为33.1 SPAD.近灯处香樟的平均胸径、当年生小枝总生产力、当年生叶片生产力及叶片相对叶绿素含量均显著高于远灯处.两处树木间比叶面积没有显著差异.夜间灯光的补充照明促进了近灯处香樟的生长,并改变了树冠生长对阳光的响应特征.

  Title What Has Been Thought and Taught on the Lunar Influence on Plants in Agriculture? Perspective from Physics and Biology Type Journal Article
  Year 2020 Publication Agronomy Abbreviated Journal Agronomy  
  Volume 10 Issue (up) 7 Pages 955  
  Keywords Moonlight; Plants  
  Abstract This paper reviews the beliefs which drive some agricultural sectors to consider the lunar influence as either a stress or a beneficial factor when it comes to organizing their tasks. To address the link between lunar phases and agriculture from a scientific perspective, we conducted a review of textbooks and monographs used to teach agronomy, botany, horticulture and plant physiology; we also consider the physics that address the effects of the Moon on our planet. Finally, we review the scientific literature on plant development, specifically searching for any direct or indirect reference to the influence of the Moon on plant physiology. We found that there is no reliable, science-based evidence for any relationship between lunar phases and plant physiology in any plant–science related textbooks or peer-reviewed journal articles justifying agricultural practices conditioned by the Moon. Nor does evidence from the field of physics support a causal relationship between lunar forces and plant responses. Therefore, popular agricultural practices that are tied to lunar phases have no scientific backing. We strongly encourage teachers involved in plant sciences education to objectively address pseudo-scientific ideas and promote critical thinking.

  Title Nighttime Mobile Laser Scanning and 3D Luminance Measurement: Verifying the Outcome of Roadside Tree Pruning with Mobile Measurement of the Road Environment Type Journal Article
  Year 2020 Publication ISPRS International Journal of Geo-Information Abbreviated Journal Ijgi  
  Volume 9 Issue (up) 7 Pages 455  
  Keywords Lighting; Plants; Instrumentation  
  Abstract Roadside vegetation can affect the performance of installed road lighting. We demonstrate a workflow in which a car-mounted measurement system is used to assess the light-obstructing effect of roadside vegetation. The mobile mapping system (MMS) includes a panoramic camera system, laser scanner, inertial measurement unit, and satellite positioning system. The workflow and the measurement system were applied to a road section of Munkkiniemenranta, Helsinki, Finland, in 2015 and 2019. The relative luminance distribution on a road surface and the obstructing vegetation were measured before and after roadside vegetation pruning applying a luminance-calibrated mobile mapping system. The difference between the two measurements is presented, and the opportunities provided by the mobile 3D luminance measurement system are discussed.

  Title Light pollution enhances temporal variability of photosynthetic activity in mature and developing biofilm Type Journal Article
  Year 2020 Publication Hydrobiologia Abbreviated Journal Hydrobiologia  
  Volume 847 Issue (up) 7 Pages 1793-1802  
  Keywords Plants; Ecology  
  Abstract Artificial light at night (ALAN) has been recently recognized as a threat for aquatic systems, but a comprehensive knowledge of its effects is still lacking. A fundamental question is whether and how ALAN might affect temporal variability of communities, thus undermining the stability of mature assemblages or influencing the colonization process. Here we investigated the role of ALAN on temporal variability of total biomass and maximum photosynthetic efficiency of marine autotrophic biofilms colonizing Mediterranean high-shore rock surfaces while controlling for density of their main grazers. Results showed stability in total biomass, but an increase in maximum photosynthetic efficiency from unlit to lit conditions, which suggested a temporal change in composition and/or abundance of different taxa within mature assemblages. The effect was weaker during the colonization process; in this case, density of grazers acted in the opposite direction of ALAN. We suggest that the addition of light at times when it would not be naturally present may affect the temporal variability of a variety of functioning in aquatic systems, depending on species-specific sensitivities to ALAN within microbial assemblages and/or indirect effects mediated by their consumers. We highlight to further investigate the role of this emergent topic in aquatic ecology.

  Title Artificial light at night as a new threat to pollination Type Journal Article
  Year 2017 Publication Nature Abbreviated Journal Nature  
  Volume 548 Issue (up) 7666 Pages 206-209  
  Keywords Plants; Animals  
  Abstract Pollinators are declining worldwide and this has raised concerns for a parallel decline in the essential pollination service they provide to both crops and wild plants. Anthropogenic drivers linked to this decline include habitat changes, intensive agriculture, pesticides, invasive alien species, spread of pathogens and climate change1. Recently, the rapid global increase in artificial light at night has been proposed to be a new threat to terrestrial ecosystems; the consequences of this increase for ecosystem function are mostly unknown. Here we show that artificial light at night disrupts nocturnal pollination networks and has negative consequences for plant reproductive success. In artificially illuminated plant–pollinator communities, nocturnal visits to plants were reduced by 62% compared to dark areas. Notably, this resulted in an overall 13% reduction in fruit set of a focal plant even though the plant also received numerous visits by diurnal pollinators. Furthermore, by merging diurnal and nocturnal pollination sub-networks, we show that the structure of these combined networks tends to facilitate the spread of the negative consequences of disrupted nocturnal pollination to daytime pollinator communities. Our findings demonstrate that artificial light at night is a threat to pollination and that the negative effects of artificial light at night on nocturnal pollination are predicted to propagate to the diurnal community, thereby aggravating the decline of the diurnal community. We provide perspectives on the functioning of plant–pollinator communities, showing that nocturnal pollinators are not redundant to diurnal communities and increasing our understanding of the human-induced decline in pollinators and their ecosystem service.
