Title Pollination by nocturnal Lepidoptera, and the effects of light pollution: a review: Moth pollination and light pollution Type Journal Article
Year 2014 Publication Ecological Entomology Abbreviated Journal (up) Ecol Entomol
Volume 40 Issue 3 Pages 187–198
Keywords Ecology; Agro-ecosystems; artificial night lighting; ecological networks; ecosystem services; flowering plants; food-webs; moths; population declines; plants; insects; pollination
Abstract 1. Moths (Lepidoptera) are the major nocturnal pollinators of flowers. However, their importance and contribution to the provision of pollination ecosystem services may have been under-appreciated. Evidence was identified that moths are important pollinators of a diverse range of plant species in diverse ecosystems across the world.

2. Moth populations are known to be undergoing significant declines in several European countries. Among the potential drivers of this decline is increasing light pollution. The known and possible effects of artificial night lighting upon moths were reviewed, and suggest how artificial night lighting might in turn affect the provision of pollination by moths. The need for studies of the effects of artificial night lighting upon whole communities of moths was highlighted.

3. An ecological network approach is one valuable method to consider the effects of artificial night lighting upon the provision of pollination by moths, as it provides useful insights into ecosystem functioning and stability, and may help elucidate the indirect effects of artificial light upon communities of moths and the plants they pollinate.

4. It was concluded that nocturnal pollination is an ecosystem process that may potentially be disrupted by increasing light pollution, although the nature of this disruption remains to be tested.

Title 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 (up) 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 Effects of artificial light on flowering of foredune vegetation Type Journal Article
Year 2019 Publication Ecology Abbreviated Journal (up) Ecology
Volume 100 Issue 5 Pages e02678
Keywords Plants; Coastal management; coastal dunes; Canary Islands; Spain; Europe
Abstract The impact of ecological light pollution involves alteration of periods of natural light, a fact that has proven effects on ecosystems. Few studies have focused on the impact of this pollution on wild plant species, and none on coastal dune plants. Many coastal dunes and their plants are adjacent to tourist areas, and these might be affected by light pollution. Such is the case of the Natural Reserve Dunas de Maspalomas (Gran Canaria), where some individuals of the plant species Traganum moquinii, located in the El Ingles beach foredune zone, are affected by light pollution. This study examines the effect of light pollution on the flowering process, and by extension the reproductive cycle of these plants. Plants located closer to high artificial illumination sources receive ~2120 hours per year of intense light more than plants located furthest from those artificial lighting sources. Parts of the plants of Traganum moquinii exposed directly to the artificial light show a significant decrease in the production of flowers, compared to the parts in plants in shade, and to the plants more distant from artificial lights. In consequence, plants exposed more directly to artificial light have a lower potential for seed reproduction. The spectrum of artificial light also affects the plants, and light between 600 and 700 nm primarily affects the reproductive cycle of the Traganum moquinii species. The implications for the ecological and geomorphological functioning of the dune system are discussed, because this species plays a decisive role in the formation of foredune zones and nebkhas in arid dune systems.

Title Effects of street lighting technologies on the success and quality of pollination in a nocturnally pollinated plant Type Journal Article
Year 2019 Publication Ecosphere Abbreviated Journal (up) Ecosphere
Volume 10 Issue 1 Pages e02550
Keywords Ecology; Animals; Plants
Abstract Artificial light at night (ALAN) is an increasingly important driver of global change. Lighting directly affects plants, but few studies have investigated indirect effects mediated by interacting organisms. Nocturnal Lepidoptera are globally important pollinators, and pollen transport by moths is disrupted by lighting. Many street lighting systems are being replaced with novel, energy‐efficient lighting, with unknown ecological consequences. Using the wildflower Silene latifolia, we compared pollination success and quality at experimentally lit and unlit plots, testing two major changes to street lighting technology: in lamp type, from high‐pressure sodium lamps to light‐emitting diodes, and in lighting regime, from full‐night (FN) to part‐night (PN) lighting. We predicted that lighting would reduce pollination. S. latifolia was pollinated both diurnally and nocturnally. Contrary to our predictions, flowers under FN lighting had higher pollination success than flowers under either PN lighting or unlit controls, which did not significantly differ from each other. Lamp type, lighting regime, and distance from the light all significantly affected aspects of pollination quality. These results confirm that street lighting could affect plant reproduction through indirect effects mediated by nocturnal insects, and further highlight the possibility for novel lighting technologies to mitigate the effects of ALAN on ecosystems.

Title Supplementary Ultraviolet Radiation B Together with Blue Light at Night Increased Quercetin Content and Flavonol Synthase Gene Expression in Leaf Lettuce (Lactuca sativa L.) Type Journal Article
Year 2008 Publication Environment Control in Biology Abbreviated Journal (up) Environ. Control Biol.
Volume 46 Issue 1 Pages 1-11
Keywords Plants
Abstract Establishment of an effective supplementary lighting procedure is necessary to increase the value of leaf lettuce grown using a hydroponic method involving a low production cost. In leaf lettuce extracts, quercetin, one of the flavonoids, was isolated and identified. It was investigated that quercetin has important functions that can be used as a dietary supplement. Flavonol synthase (FLS) is a key enzyme involved in quercetin biosynthesis, catalyzes the conversion of dihydroquercetin to quercetin. Therefore, we determined the sequence of the flavonol synthase gene (FLS) in red leaf lettuce. We harvested leaf lettuce grown using supplementary light sources, such as ultraviolet radiation B (UV-B), ultraviolet radiation A, blue, and red lamps during the night. It is noteworthy that FLS expression and the quercetin content were particularly increased to a greater extent in young leaves than in mature leaves when UV-B and blue light were used simultaneously at night. We suggest that UV-B with blue light is used simultaneously at night for producing leaf lettuce with high quercetin content.
