| Abstract |
BACKGROUND: It is now well documented that moonlight affects the life cycle of invertebrates, birds, reptiles, and mammals. The lunisolar tide is also well-known to alter plant growth and development. However, although plants are known to be very photosensitive, few studies have been undertaken to explore the effect of moonlight on plant physiology. RESULTS: Here for the first time we report a massive transcriptional modification in Coffea arabica genes under full moonlight conditions, particularly at full moon zenith and 3 h later. Among the 3387 deregulated genes found in our study, the main core clock genes were affected. CONCLUSIONS: Moonlight also negatively influenced many genes involved in photosynthesis, chlorophyll biosynthesis and chloroplast machinery at the end of the night, suggesting that the full moon has a negative effect on primary photosynthetic machinery at dawn. Moreover, full moonlight promotes the transcription of major rhythmic redox genes and many heat shock proteins, suggesting that moonlight is perceived as stress. We confirmed this huge impact of weak light (less than 6 lx) on the transcription of circadian clock genes in controlled conditions mimicking full moonlight. |

| Abstract |
Technology, especially artificial light at night (ALAN), often has unexpected impacts on the environment. This chapter addresses both the perception of light by various organisms and the impact of ALAN on flora and fauna. The responses to ALAN are subdivided into the effects of light intensity, color spectra, and duration and timing of illumination. The ways organisms perceive light can be as variable as the habitats they live in. ALAN often interferes with natural light information. It is rarely neutral and has significant impacts beyond human perception. For example, UV light reflection of generative plant parts or the direction of light is used by many organisms as information for foraging, finding spawning sites, or communication. Contemporary outdoor lighting often lacks sustainable planning, even though the protection of species, habitat, and human well-being could be improved by adopting simple technical measures. The increasing use of ALAN with high intensities in the blue part of the spectrum, e.g., fluorescent light and LEDs, is discussed as a critical trend. Blue light is a major circadian signal in higher vertebrates and can substantially impact the orientation of organisms such as numerous insect species. A better understanding of how various types and sources of artificial light, and how organisms perceive ALAN, will be an important step towards more sustainable lighting. Such knowledge is the basis for sustainable lighting planning and the development of solutions to protect biodiversity from the effects of outdoor lighting. Maps that describe the rapid changes in ALAN are urgently needed. In addition, measures are required to reduce the increasing use and intensity of ALAN in more remote areas as signaling thresholds in flora and fauna at night are often close to moonlight intensity and far below streetlight levels. |

| 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. |

| Abstract |
Artificial light at night (ALAN) is a widespread phenomenon along coastal areas. Despite increasing evidence of pervasive effects of ALAN on patterns of species distribution and abundance, the potential of this emerging threat to alter ecological processes in marine ecosystems has remained largely unexplored. Here, we show how exposure to white LED lighting, comparable to that experienced along local urbanized coasts, significantly enhanced the impact of grazing gastropods on epilithic microphytobenthos (MPB). ALAN increased both the photosynthetic biomass of MPB and the grazing pressure of gastropods, such that consumers compensated for the positive effect of night lighting on primary producers. Our results indicate that trophic interactions can provide a stabilizing compensatory mechanism against ALAN effects in natural food webs. |
