| Abstract |
Starting with the beginning of the last century, a multitude of scientific studies has documented that the lunar cycle times behaviors and physiology in many organisms. It is plausible that even the first life forms adapted to the different rhythms controlled by the moon. Consistently, many marine species exhibit lunar rhythms, and also the number of documented “lunar-rhythmic” terrestrial species is increasing. Organisms follow diverse lunar geophysical/astronomical rhythms, which differ significantly in terms of period length: from hours (circalunidian and circatidal rhythms) to days (circasemilunar and circalunar cycles). Evidence for internal circatital and circalunar oscillators exists for a range of species based on past behavioral studies, but those species with well-documented behaviorally free-running lunar rhythms are not typically used for molecular studies. Thus, the underlying molecular mechanisms are largely obscure: the dark side of the moon. Here we review findings which start to connect molecular pathways with moon-controlled physiology and behaviors. The present data indicate connections between metabolic/endocrine pathways and moon-controlled rhythms, as well as interactions between circadian and circatidal/circalunar rhythms. Moreover, recent high-throughput analyses provide useful leads towards pathways, as well as molecular markers. However, for each interpretation it is important to carefully consider the – partly substantially differing – conditions used in each experimental paradigm. In the future, it will be important to use lab experiments to delineate the specific mechanisms of the different solar- and lunar-controlled rhythms, but to also start integrating them together, as life has evolved equally long under rhythms of both sun and moon. |

| Abstract |
Artificial Light at Night (ALAN) may have various environmental impacts ranging from compromising the visibility of astronomical objects to the perturbation of circadian cycles in animals and humans. In the past much research has been carried out to study the impact of ALAN on the radiance of the night sky during clear sky conditions. This was mainly justified by the need for a better understanding of the behavior of ALAN propagation into the environment in order to protect world-class astronomical facilities. More recently, alongside to the threat to the natural starry sky, many issues have emerged from the biological science community. It has been shown that, nearby or inside cities, the presence of cloud cover generally acts as an amplifier for artificial sky radiance while clouds behave as attenuators for remote observers. In this paper we show the spectral behavior of the zenith sky radiance amplification factor exerted by clouds inside a city. We compare in-situ measurements made with the spectrometer SAND-4 with a numerical model applied to the specific geographical context of the Universidad Complutense de Madrid in Spain. |

| Abstract |
Urban agglomeration is the engine of national development and regional prosperity. Although extensive work has investigated issues related to this new form of spatial governance, few studies have directly illustrated the spatial integration of urban agglomeration and its relationship with industrial development. This paper employs nighttime light data and industrial enterprise datasets to investigate the spatial integration and industrial development in the Yangtze River Economic Belt (YREB) of China for 1995–2015. We here illustrate the significant relationship between the spatial integration of urban agglomerations and the characteristics of industrial development. In the process of spatial integration, urban form, intercity relation and their evolution show clear regional differences. Because of the differences in socio-economic and geographical characteristics, urban systems are more advanced and closely related in developed areas. A significant negative (positive) spatial correlation between industrial specialization (diversification) and urban form is supported by using bivariate Moran's I, and spatial clustering patterns are clearly different across the three urban agglomerations. A panel regression reveals that intercity relations are significantly associated with the characteristics of industrial development. Higher levels of industrial diversification and competition are associated with weaker intercity relations, while industrial structures similarities are reversed. These findings could be used to formulate reasonable policies and plans and to support future regional spatial integration and coordinated development. |

| Abstract |
China's rural e-commerce has been developing quickly over the last decade, and it has shown significant spatial aggregation in some areas. This paper examines this development and investigates factors that impact its spatial aggregation. The development of Taobao Villages is a typical example that reflects the fast development and spatial aggregation of rural e-commerce in villages. Thus, all the Taobao Villages that existed in China by 2017 are used as our research sample for the empirical analysis. Considering that village-level data involving long-term and large-scale observations are lacking in China, we innovatively combine report data from Alibaba, spatial data from Geography Information Systems technology, company data from web crawler technology and nighttime light data from remote sensing technology to quantify the factors of interest for each sample village. Ultimately, the consistent results of a random-effects probit model based on data about 2266 villages across six years and a negative binominal model based on cross-section data of 2092 villages demonstrates that the spatial aggregation at village-level with regard to rural e-commerce is significantly driven by the local industrial base and neighborhood effects. Interestingly, the socioeconomic conditions of the surrounding regions that villages locate in impact the spatial aggregation of rural e-commerce significantly and it presents non-linear relationship between them, but the local socioeconomic conditions of villages per se do not present significant impacts on it. This paper concludes with the policy implication for the promotion of spatial aggregation of rural e-commerce. |
