  Title (up) Light Pollution Changes the Toxicological Effects of Cadmium on Microbial Community Structure and Function Associated with Leaf Litter Decomposition Type Journal Article
  Year 2020 Publication International Journal of Molecular Sciences Abbreviated Journal Int J Mol Sci  
  Volume 21 Issue 2 Pages  
  Keywords Plants; Illumina Sequencing; artificial light at night; cadmium pollution; extracellular enzyme activities; litter decomposition; microbial biodiversity  
  Abstract Artificial light at night (ALAN/A) can not only alter the behavior and communication of biological organisms, it can also interact with other stressors. Despite its widespread use and the numerous potential ecological effects, little is known about the impact of ALAN on plant litter decomposition under cadmium (Cd) pollution in aquatic ecosystems. In an indoor microcosm experiment, we tested single and combined effects of ALAN and Cd on the activities and community structure of fungi associated with plant litter. The results showed that ALAN and/or Cd can change both water and leaf litter characteristics. ALAN exposure not only altered fungal community structure and their correlations, but also increased the activities of alkaline phosphatase, beta-glucosidase, and cellobiohydrolase. The leaf litter decomposition rate was 71% higher in the A-Cd treatment than that in the N-Cd treatment, indicating that the presence of ALAN weakened the negative impact of Cd on leaf litter decomposition. These results suggested that ALAN exposure mitigated the negative effect of Cd on leaf litter decomposition, contributing to the duel effect of ALAN on leaf litter decomposition. Overall, the results expand our understanding of ALAN on the environment and highlight the contribution of ALAN to Cd toxicity in aquatic ecosystems.

  Title (up) Light pollution is associated with earlier tree budburst across the United Kingdom Type Journal Article
  Year 2016 Publication Proceedings of the Royal Society B: Biological Sciences Abbreviated Journal Proc Roy Soc B Biol Sci  
  Volume 283 Issue 1833 Pages 1-9  
  Keywords Plants; light pollution, phenology, species interactions, tree budburst, temperature, urban heat islands; United Kingdom  
  Abstract The ecological impact of night-time lighting is of concern because of its well-demonstrated effects on animal behaviour. However, the potential of light pollution to change plant phenology and its corresponding knock-on effects on associated herbivores are less clear. Here, we test if artificial lighting can advance the timing of budburst in trees. We took a UK-wide 13 year dataset of spatially referenced budburst data from four deciduous tree species and matched it with both satellite imagery of night-time lighting and average spring temperature. We find that budburst occurs up to 7.5 days earlier in brighter areas, with the relationship being more pronounced for later-budding species. Excluding large urban areas from the analysis showed an even more pronounced advance of budburst, confirming that the urban ‘heat-island’ effect is not the sole cause of earlier urban budburst. Similarly, the advance in budburst across all sites is too large to be explained by increases in temperature alone. This dramatic advance of budburst illustrates the need for further experimental investigation into the impact of artificial night-time lighting on plant phenology and subsequent species interactions. As light pollution is a growing global phenomenon, the findings of this study are likely to be applicable to a wide range of species interactions across the world.

  Title (up) Light pollution on the growth, physiology and chlorophyll fluorescence response of landscape plant perennial ryegrass (Lolium perenne L.) Type Journal Article
  Year 2020 Publication Ecological Indicators Abbreviated Journal Ecological Indicators  
  Volume 115 Issue Pages 106448  
  Keywords Plants  
  Abstract Perennial ryegrass (Lolium perenne L.) was commonly used for urban green planting such as lawns, which was not only affected by sunlight, but also by light pollution caused by night artificial lighting. In order to see the ryegrass growth, physiological characters and chlorophyll fluorescence response to light pollution and provide the suitable lighting time, 6 different artificial lighting times (24/0 h, 22/2 h, 20/4 h, 18/6 h, 16/8 h and 14/10 h) were conducted in growth chambers. There were significant systematic differences in perennial ryegrass growth characters in seed germination rate, leaf length (LL) and leaf weight (LW) (F = 47.99, 28.34, 13.47, respectively; P < 0.01) while under 16/8h lighting time treatment which had the highest values and the increasing lighting time decreased the growth. It had the best effect under 16/8h lighting time treatment on leaf physiological reactions and also significant. The maximum curvature point temperature (TCC) was significant different (F = 28.08, P < 0.01). The relative variable fluorescence differences at 2 ms (VJ) was increased with the lighting time increased (F = 20.25, P < 0.01). The results of reaction center (RC) of PSII under 6 lighting times also had significant differences. For the result of the yield and efficiency of electron transport chain (ETC), Fv/Fm (φP0), ψ0 and φE0 showed the significantly increased trend with the lighting time decreased while the φD0 was decreased. The shape of the OJIP curves was sensitive to the lighting times which showed that with the increasing lighting times the chlorophyll fluorescence intensity changed and shifted the fluorescence curve lower. Leaf light-response curves (LC) were also significant under 6 lighting times. Significant positive correlations were found between leaf physiological characters (SP, SC, Chl a, Chl b, Chl a + b, WP and TCC) and J-I-P test chlorophyll fluorescence parameters (PIABS, ABS/RC and TR0/RC) except ET0/RC while the correlation with DI0/RC was significant negative. There were significant positive correlations between leaf physiological characters (SP, SC, Chl a, Chl b, Chl a + b, WP and TCC) and φP0, φE0, ψ0 while the relationships with φD0 were significantly negative. Nighttime artificial lighting acted as a depressor of the fitness of photosynthesis and growth characters, via the changing of the photosynthetic apparatus.

  Title (up) Moonlight pollination in the gymnosperm Ephedra (Gnetales) Type Journal Article
  Year 2015 Publication Biology Letters Abbreviated Journal Biol. Lett.  
  Volume 11 Issue 4 Pages 20140993  
  Keywords Plants; anemophily; entomophily; lunar phases; nocturnal insects; lunar cycle; light at night; Ephedra; Ephedra distachya; pollination  
  Abstract Most gymnosperms are wind-pollinated, but some are insect-pollinated, and in Ephedra (Gnetales), both wind pollination and insect pollination occur. Little is, however, known about mechanisms and evolution of pollination syndromes in gymnosperms. Based on four seasons of field studies, we show an unexpected correlation between pollination and the phases of the moon in one of our studied species, Ephedra foeminea. It is pollinated by dipterans and lepidopterans, most of them nocturnal, and its pollination coincides with the full moon of July. This may be adaptive in two ways. Many nocturnal insects navigate using the moon. Further, the spectacular reflection of the full-moonlight in the pollination drops is the only apparent means of nocturnal attraction of insects in these plants. In the sympatric but wind-pollinated Ephedra distachya, pollination is not correlated to the full moon but occurs at approximately the same dates every year. The lunar correlation has probably been lost in most species of Ephedra subsequent an evolutionary shift to wind pollination in the clade. When the services of insects are no longer needed for successful pollination, the adaptive value of correlating pollination with the full moon is lost, and conceivably also the trait.

  Title (up) Night Light-Adaptation Strategies for Photosynthetic Apparatus in Yellow-Poplar (Liriodendron tulipifera L.) Exposed to Artificial Night Lighting Type Journal Article
  Year 2018 Publication Forests Abbreviated Journal Forests  
  Volume 9 Issue 2 Pages 74  
  Keywords Plants  
  Abstract Plants can undergo external fluctuations in the natural light and dark cycle. The photosynthetic apparatus needs to operate in an appropriate manner to fluctuating environmental factors, especially in light. Yellow-poplar seedlings were exposed to nighttime artificial high-pressure sodium (HPS) lighting to evaluate night light-adaptation strategies for photosynthetic apparatus fitness relative to pigment contents, photosystem II photochemistry, photosynthetic parameters, histochemical analysis of reactive oxygen species, and plant biomass. As a result, seedlings exhibited dynamic changes including the enhancement of accessory pigments, the reduction of photosystem II photochemistry, increased stomatal limitation, downregulation of photosynthesis, and the decreased aboveground and belowground biomass under artificial night lighting. Histochemical analysis with 3,3&#8242;-diaminobenzidine (DAB) and nitroblue tetrazolium (NBT) staining indicates the accumulation of in situ superoxide radicals (O2&#8722;) and hydrogen peroxide (H2O2) in leaves exposed to the lowest level of artificial night lighting compared to control. Moreover, these leaves exposed to artificial night lighting had a lower nighttime respiration rate. These results indicated that HPS lighting during the night may act as a major factor as repressors of the fitness of photosynthesis and growth patterns, via a modification of the photosynthetic light harvesting apparatus.
