  Title Effects of prolonged night-time light exposure and traffic noise on the behavior and body temperature rhythmicity of the wild desert rodent, Gerbillus tarabuli Type Journal Article
  Year (down) 2021 Publication Chronobiology International Abbreviated Journal Chronobiol Int  
  Volume in press Issue Pages  
  Keywords Animals; Anxiety; behavior; body temperature rhythm; circadian rhythmicity; night light; stress; traffic noise  
  Abstract The aim of this study was to demonstrate for the first time in Tarabul's gerbils (Gerbillus tarabuli), the effects of simultaneous exposure to two major environmental stressors – light and noise pollutions – on the body temperature rhythm and anxious behavior. Seven groups, each consisting of 6 adult male gerbils, were subjected to a standard LD cycle (12 L:12D) with lights on at 08:00 h and off at 20:00 h, constant conditions (total darkness, DD), prolonged nighttime exposure to light (PEL: 18 L:6D) with lights on at 08:00 h and off at 02:00 h, mimicking prolonged exposure to light pollution in peri-urban areas, exposure to auditory stress (TNS) of 80 dB, and conditions combining PEL&TNS. The body temperature circadian rhythm was recorded, and behavioral tests were performed at the end of experimental phases. The results revealed the existence, for the first time in Gerbilus tarabuli, of an endogenous circadian rhythm of body temperature with a period of 23.8 +/- 0.04 h. Prolonged exposure to light at night (PEL) induced a significant phase delay (02 h 09 min +/- 0.16 h) of the rhythm, with an acrophase (peak time) occurring at 04:42 +/- 0.13 h instead of 02:33 +/- 0.21 h. Exposure to TNS for 4 hours per night induced a significant increase of the amplitude of the rhythm and a decrease of the rhythm regularity (robustness of 73.26% in TNS vs. 82.32 in control condition). While combining TNS and PEL significantly delayed the phase of the Tb rhythm by 3 h 10 min (acrophase at 06:39 +/- 0.37 h instead of 02:33 +/- 0.21 h), increased the amplitude, and significantly reduced the stability of the rhythm (robustness of 67.25% in PEL&TNS vs. 82.32 in control condition). PEL&TNS and TNS environments induce an important stress in gerbils highlighted by a significant decrease of the number of line crossings and time spent in the center area of the open field test. Furthermore, elevated plus maze test revealed gerbils of the PEL&TNS and TNS conditions significantly visited the lowest number of open arms and spent a shorter amount of time in it. In addition, these conditions were responsible for less activity (total number of entries in arms) than in the control and PEL conditions. These results indicate clearly that in the desert area, peri-urban light and noise pollutions disturb the circadian rhythm components and alter the behavior of Tarabul's gerbils inducing an anxious state.

  Title Evaluation of China's High-Speed Rail Station Development and Nearby Human Activity Based on Nighttime Light Images Type Journal Article
  Year (down) 2021 Publication International Journal of Environmental Research and Public Health Abbreviated Journal Int J Environ Res Public Health  
  Volume 18 Issue 2 Pages  
  Keywords Remote sensing; Npp/Viirs; brightness; high-speed rail (HSR); human activity; station development  
  Abstract High-speed rail (HSR) represents China's advancing productivity; however, quite a few HSR stations face problems due to inappropriate planning and limited passenger flow. To optimize future planning on HSR lines and stations and facilitate efficient operation, we used brightness as a representative of station development and nearby human activity, analyzing its spatial and temporal distribution, classification categories, and influencing factors of 980 stations using nighttime light images from 2012 to 2019. The following conclusions were drawn: (1) There are 41 stations with high brightness between 80 and 320 nW.cm(-2).sr(-1), which are concentrated in provincial capitals, large cities, and at line ends. The overall number of these stations increases by 57% in the past eight years. (2) Stations with high brightness but minimal changes that opened in 2013-2019 are mainly concentrated in provincial capitals and large- or medium-sized cities, and those with high brightness and significant changes are mostly new stations nearby. More than 70% of stations that started HSR operation before or in 2012 have high brightness. (3) Brightness positively correlates with the number of daily trains, and it changes faster at stations with more daily trains. It changes most within 0-1 year after HSR operation opening and exhibits a relatively slow but long-term increase over the next 2-6 years.

  Title Effect of illumination on fish and amphibian: development, growth, physiological and biochemical processes Type Journal Article
  Year (down) 2021 Publication Reviews in Aquaculture Abbreviated Journal Rev. Aquacult.  
  Volume 13 Issue 1 Pages 567-600  
  Keywords Review; Animals  
  Abstract Being one of the main environmental factors, the light factor influences many aspects of animal life. Photoperiod, light intensity (illumination) and wavelength are the primary periodic factors. There is a review that discusses the role of illumination on various life processes of aquatic anamnia vertebrates (fish and amphibians). The effect of light on the development, growth, respiration, consumption and efficiency of food conversion, hormone release, reproduction and behaviour of fish and amphibians has been studied. Illumination influences differently a significant number of physiological and biochemical processes and reactions of anamnia vertebrates at various development stages. The obtained results show that the nature of exposure to light is species‐specific and corresponds to the ecological niche of species. Illumination influences both positively and negatively the development, growth and other physiological processes of fish and amphibians. Illumination plays a special role during the first feeding of fish in the environment and aquaculture. There are positive and negative behavioural responses of fish to light. However, it is not always possible to distinguish fish species with only a negative or only a positive reaction to light. The quality of the reaction can be influenced by the stage of development of eggs or larvae, age characteristics, feeding status, season, time, the physiological state of fish, morbidity, etc. A promising area of research is the study of the influence of light on the hormonal status of the body and reproduction of fish. Also, the light pollution and its influence on the physiology of anamnia vertebrates are important.

  Title Impacts of urbanization on precipitation patterns in the greater Beijing–Tianjin–Hebei metropolitan region in northern China Type Journal Article
  Year (down) 2021 Publication Environmental Research Letters Abbreviated Journal Environ. Res. Lett.  
  Volume 16 Issue 1 Pages 014042  
  Keywords Remote Sensing  
  Abstract We present a statistical method to quantify the contribution of urbanization to precipitation changes during 1958–2017 across the greater Beijing–Tianjin–Hebei metropolitan region in northern China. We find distinct trends in precipitation in the past six decades: decreasing in annual and summer while increasing in other seasons. The spatial patterns of precipitation show discernible terrain-induced characteristics with high values in the buffer zones of plain and mountain areas and low values in the northwestern mountainous regions. Our results indicate that although urbanization has limited impacts on the trends and spatial patterns of precipitation, it has a positive contribution to the changes in precipitation for about 80% of the comparisons conducted, especially in autumn (100%), with the negative contribution being dominant in summer (66.67%). In addition, these results are sensitive to the classifications of urban and rural stations, suggesting that how to classify urban/rural areas is a crucial step to estimate the potential contribution of urbanization to precipitation changes. These findings also support that urbanization can diversify and enhance the variations in precipitation, with urban areas becoming a secondary center along with more increasing or less decreasing trends in precipitation.

  Title Measuring urban compactness based on functional characterization and human activity intensity by integrating multiple geospatial data sources Type Journal Article
  Year (down) 2021 Publication Ecological Indicators Abbreviated Journal Ecological Indicators  
  Volume 121 Issue Pages 107177  
  Keywords Remote Sensing  
  Abstract Compact development is one of the most effective solutions for sustainable urbanization under the rapid growth of the urban population. Great efforts have been made to measure urban physical compactness while limited attention has been paid to functional zoning of urban areas. Here, we introduce a novel index, called the functional compactness index (FCI), to quantify urban functional compactness through the integration of geospatial data sources, including Points of Interest (POIs) data, Road Network of OpenStreetMap (RNO) data, and National Polar-orbiting Partnership (NPP) Visible Infrared Imaging Radiometer Suite (VIIRS) nighttime light data. The FCI does not require the analysis of the grid scale and thus, is technically simpler than conventional compactness index (CI). We examined the effectiveness of FCI on estimating urban compactness under four land use scenarios and in four Chinese cities. The results suggest that: (1) the FCI can comprehensively reflect the intensity of human activity, the differentiation between residential zones and other functional zones, and the mixing degree of different functional zones; (2) the FCI is not affected by the service radius of residential zones; (3) the FCI can reflect the overall and local-scale functional compactness of a city; and (4) the FCI can be used to effectively compare spatial characteristics of functional compactness among different cities. In conclusion, the FCI considers the rationality of urban functional layout, which not only is helpful for urban planning, but also enriches the quantitative methods of urban compactness evaluation.
