“…We did not consider the lunar cycle within our study design, since previous studies on bat “lunar phobia” provide contradictory evidence suggesting divergent geographical and species-specific patterns 48 : while for some species moonlight intensity influences activity (e.g. 49 , 50 ), this effect could not be confirmed for other species 51 – 53 . We made full spectrum recordings in .raw format [sampling rate: 500 kHz, record quality: 20, amplitude resolution: 16 bit, threshold amplitude (sensitivity): − 36 dB, post trigger: 400 ms, threshold frequency (sensitivity): 16 kHz].…”

Urbanization gradients are increasingly used in ecological studies to discover responses of species communities to different intensities of human-induced habitat transformation. Here, we investigated patterns of bat communities against the background of different urbanization levels using a priori defined urbanization categories based on distance classes (5 km intervals) along a linear transect from the urban core of the city of Berlin westwards into the rural outskirts of the state of Brandenburg. Using linear-mixed effects models, we found that “distance class”, as a proxy for urbanization level, is a meaningful and suitable predictor of bat species richness and diversity. We observed an unexpectedly sudden increase in bat species richness and diversity and changes in species-specific activity levels relatively close to the urban center at the transition between urban and peri-urban areas. This change suggests a relevant influence of the peri-urban areas as a “buffer zone” for specific bat species not able to adapt to the heavily modified inner core of the metropolitan area. Although we could demonstrate that anthropogenic noise and artificial light have the potential to predict the variability of bat species activity along the urban–rural gradient, the actual influence on observed shifts in the bat community needs further research.

“…Within a night, different species are active at different times to partition the niche, forming species-specific diel activity patterns [24]. Variations of a species' diel activity patterns may occur when bats respond to changes or disturbances in the environment, such as seasonality, anthropogenic light, or noises [25][26][27]. When a species' diel activity patterns vary across different habitats, it indicates differences in how bats use these habitats and what resources each habitat might provide [28][29][30].…”

In grassland ecosystems, agriculture and urbanization are two main anthropogenic disturbances to native fauna. Nature preserves at the urban-agricultural interface may include diverse vegetation habitats, providing opportunities for native fauna. Limited research has examined the conservation value of such preserves to bats. We examined bat activity patterns at multiple temporal scales at Glacier Creek Preserve in Omaha, Nebraska, USA, between 2018 and 2020 via acoustic monitoring to identify what functional habitats it might provide to bats. We placed bat detectors along the forest edge and in the open, restored native prairies and open agricultural fields. A total of nine species were recorded at the preserve, including the endangered Myotis septentrionalis. Foraging activities were recorded for six species. The edge habitat had higher overall acoustic activities for three species (Eptesicus fuscus, Lasiurus borealis, and Lasiurus cinereus) and a higher proportion of foraging activities for two species (Lasiurus borealis and Lasiurus cinereus) than the open habitat. Lasiurus cinereus displayed activity peaks early at night, whereas Lasiurus borealis had activity peaks late. Results suggest that a medium-sized nature preserve at the urban-agricultural interface can provide roosts, commuting corridors, and foraging grounds for different bats. The conservation value of such nature preserves should not be overlooked.

“…In recent years, environmental and social problems caused by light pollution have become more and more serious. Light pollution was first proposed by the international astronomical community in the 1930s, and astronomers feel that the bright light of cities has a great impact on astronomical observations [1][2][3]. Light pollution is a new source of environmental pollution, mainly including white and bright pollution, artificial day pollution, and lighting pollution, at the same time, the phenomenon of light pollution is called light intrusion, excessive lighting, and stray light.…”

With the continuous development of society, light pollution has become a hot issue in the field of regional governance and sustainable development. It is of high research value to make accurate and based classification of light pollution risk levels in a region. In this paper, 31 provinces and regions in China were selected as research samples, combined with social development, population, and other five levels, and multi-stage indicators were used to construct a light pollution risk level evaluation index system. The subjective and objective weights of each index were determined by the analytic hierarchy process (AHP) and entropy weight method, and the combined weights were determined by minimizing the deviation between the basic weights based on game theory. The results showed that the top three weights were regional per capita GDP, urban population density, and per capita consumption expenditure of all residents respectively. On this basis, a rank-sum ratio comprehensive evaluation model was established. The light pollution risk levels of 31 research samples were divided into four levels, including 3 high-risk areas, 13 medium-high-risk areas, 13 medium-risk areas, and 2 low-risk areas.
