Title The full moon as a synchronizer of circa-monthly biological rhythms: Chronobiologic perspectives based on multidisciplinary naturalistic research Type Journal Article
Year 2016 Publication Chronobiology International Abbreviated Journal Chronobiol Int
Volume (up) 33 Issue 5 Pages 465-479
Keywords Moonlight; Commentary; Animals; Plants; Human Health
Abstract Biological rhythmicity is presumed to be an advantageous genetic adaptation of fitness and survival value resulting from evolution of life forms in an environment that varies predictably-in-time during the 24 h, month, and year. The 24 h light/dark cycle is the prime synchronizer of circadian periodicities, and its modulation over the course of the year, in terms of daytime photoperiod length, is a prime synchronizer of circannual periodicities. Circadian and circannual rhythms have been the major research focus of most scientists. Circa-monthly rhythms triggered or synchronized by the 29.5 day lunar cycle of nighttime light intensity, or specifically the light of the full moon, although explored in waterborne and certain other species, have received far less study, perhaps because of associations with ancient mythology and/or an attitude naturalistic studies are of lesser merit than ones that entail molecular mechanisms. In this editorial, we cite our recent discovery through multidisciplinary naturalistic investigation of a highly integrated circadian, circa-monthly, and circannual time structure, synchronized by the natural ambient nyctohemeral, lunar, and annual light cycles, of the Peruvian apple cactus (C. peruvianus) flowering and reproductive processes that occur in close temporal coordination with like rhythms of the honey bee as its pollinator. This finding led us to explore the preservation of this integrated biological time structure, synchronized and/or triggered by environmental light cues and cycles, in the reproduction of other species, including Homo sapiens, and how the artificial light environment of today in which humans reside may be negatively affecting human reproduction efficiency.

Title Assessing the impact of street lighting on Platanus x acerifolia phenology Type Journal Article
Year 2018 Publication Urban Forestry & Urban Greening Abbreviated Journal Urban Forestry & Urban Greening
Volume (up) 34 Issue Pages 71-77
Keywords Plants
Abstract Autumn phenology is an important part of the tree growing season that is still poorly understood. In addition to the environmental factors that might affect its timing, there are artificial effects introduced by modern society that could interfere with it, such as the increasing use of artificial light to illuminate urban nights. This study investigates the relationship between outdoor public lighting and leaf senescence of Platanus x acerifolia that constitutes with more than 4000 individuals, and 6% of public greening in Florence, Italy. The difference in autumn phenology under two lighting conditions was assessed by analysing data collected in a real context, using a presence-absence protocol of green leaves on 283 trees during leaf fall season from 2014 to 2017. Trees were classified in two groups of different light exposure. In 2016-2017, data were also collected at Cascine park, the main green area within the city and darker than the monitored sites. According to the analysis, the percentage of trees with green leaves under luminaires was significantly higher than trees far from the luminaires, for all sites from mid-December to the end of January, and this effect was enhanced during 2016-2017 which was characterised by a colder winter. In the same year, the period of absence of green leaves at Cascine started at least 20 days earlier than the other sites. These findings should be taken into consideration by scientists because artificial light could affect autumn phenology and therefore the length of the vegetative season, and by urban greening and light managers during the design and management of public green spaces. Moreover, the presence-absence protocol proved to be suitable for collecting observations because it was easy to perform in a real context.

Title Influence of lunar cycles on growth of Ashwagandha (Withania somnifera [L.] Dunal) Type Journal Article
Year 2015 Publication Ayu Abbreviated Journal Ayu
Volume (up) 36 Issue 3 Pages 258-264
Keywords Plants; Moonlight
Abstract INTRODUCTION: Ayurvedic classics have advocated to collect the medicinal plants according to part used and seasons in order to get desired pharmacological action and therapeutic benefits. The logic behind this principle is being validated by recent researches. AIM: To analyze the influence of lunar cycles on growth of Ashwagandha in Shishira and Greeshma Ritu (winter and summer season). MATERIALS AND METHODS: Fourteen small crops of Ashwagandha of average size 10 cm were collected on October 7, 2013, from institute campus and then replantation was done at Charaka Herbal Garden, Gujarat Ayurved University, Jamnagar in an area of 60 cm x 60 cm (l x b). No fertilizers or pesticides were used. The plants were watered daily and plants were uprooted as per lunar cycles for analysis. Eight samples were collected and observed during Shishira and Greeshma season on Pournima (full moon) and Amavasya (new moon) days. The measurements were taken thrice and average values were taken into consideration for study purpose. The variations in morphological characteristics such as length, breadth, weight, and number of roots and twigs were studied through statistical procedure of principle component analysis, which makes interpretation of all possible related variables. RESULTS: Root weight (RW), pith diameter (PD) and internodal distance (ID) were found to be increased on full moon days as compared to new moon days. The maximum RW was observed during Greeshma Aashadha Pournima. CONCLUSION: The study has shown a definite influence of lunar cycles on the growth of the plant parts assessed by RW, PD, and ID that have found to be increased on full moon days as compared to new moon days.
