Title (up) Exploring spatiotemporal patterns of electric power consumption in countries along the Belt and Road Type Journal Article
Year 2018 Publication Energy Abbreviated Journal Energy
Volume 150 Issue Pages 847-859
Keywords Remote Sensing
Abstract Fully understanding spatiotemporal patterns of electric power consumption (EPC) is one of the key questions related to sustainable socioeconomic and environmental development in countries along the Silk Road Economic Belt and the 21st-Century Maritime Silk Road (hereinafter referred to as the Belt and Road countries). However, studies about spatiotemporal patterns of EPC in the Belt and Road countries are still scarce due to the lack of reliable data. This study attempted to investigate spatiotemporal patterns of EPC in the Belt and Road countries from multiple perspectives. Firstly, the Defense Meteorological Satellite Program’s Operational Linescan System (DMSP-OLS) nighttime stable light data were used to estimate EPC from 1992 to 2013. Subsequently, the mathematical statistic method, standard deviational ellipse, rank size rule, and correlation analysis were employed to evaluate the EPC change in detail. The results reveal that the EPC growth mainly occurs in the developing countries, especially in China. The geographical distribution of EPC in the Belt and Road countries is oriented in the Northwest-Southeast direction between 1992 and 2013. Based on the rank size rule analysis, the slope values of q are −2.392 and −2.175 between 1992 and 2013, with an average R2 value of 0.664, indicating a clear clustering pattern of EPC. It is also proved that GDP is a more important impact factor to EPC than the population. Our findings can offer an effective way to understand spatiotemporal evolution characteristics of EPC in the Belt and Road countries, and provide references for regional socioeconomic development and cooperation.

Title (up) Exploring The Role of Artificial Lighting in Loggerhead Turtle (Caretta caretta) Nest-Site Selection and Hatchling Disorientation Type Journal Article
Year 2018 Publication Herpetological Conservation and Biology Abbreviated Journal
Volume 13 Issue 2 Pages 415-422
Keywords Animals
Abstract Beachfront artificial lighting can deter nesting sea turtles and disrupt the seaward orientation of hatchlings following their emergence from the nest. We investigated the effects of variable artificial lighting along the 17.5-km beachfront of St. George Island, Florida, USA on both nesting and hatchling Loggerhead Turtles (Caretta caretta). We hypothesized that illumination affects nest-site selection and hatchling orientation of Loggerhead Turtles. We predicted that zones with higher artificial luminance levels would have a reduced number of nests laid by Loggerhead Turtles, as well as an increased hatchling disorientation rate. We divided the beachfront into zones 500 m in length and recorded nighttime luminance measurements with a photometer throughout the 2015 nesting season. The 2015 luminance values were analyzed together with Loggerhead Turtle nesting data from the 2015 season, as well as related to a longer-term dataset from 2011–2015. We found a negative relationship between nestsite selection and the intensity of artificial luminance, such that the brighter zones along the beachfront had fewer nests. Within this relationship, we found that nest density was significantly lower above a beachfront luminance value of ~800 μcd/m2. Finally, we found that hatchling disorientations occurred more frequently in zones with greater luminance. While many factors can affect nesting and hatchling Loggerhead behavior, our results suggest that variable intensities of artificial lighting at a nesting site may lead to a spatially clumped arrangement of nests and hatchling disorientations. These results can help improve the conservation and protection of nesting habitat as they further our understanding of the effects of artificial beachfront lighting on Loggerhead Turtles.

Title (up) Exposure to 4100K fluorescent light elicits sex specific transcriptional responses in Xiphophorus maculatus skin Type Journal Article
Year 2018 Publication Comparative Biochemistry and Physiology. Toxicology & Pharmacology : CBP Abbreviated Journal Comp Biochem Physiol C Toxicol Pharmacol
Volume 208 Issue Pages 96-104
Keywords Animals
Abstract It has been reported that exposure to artificial light may affect oxygen intake, heart rate, absorption of vitamins and minerals, and behavioral responses in humans. We have reported specific gene expression responses in the skin of Xiphophorus fish after exposure to ultraviolet light (UV), as well as, both broad spectrum and narrow waveband visible light. In regard to fluorescent light (FL), we have shown that male X. maculatus exposed to 4100K FL (i.e. “cool white”) rapidly suppress transcription of many genes involved with DNA replication and repair, chromosomal segregation, and cell cycle progression in skin. We have also detailed sex specific transcriptional responses of Xiphophorus skin after exposure to UVB. However, investigation of gender differences in global gene expression response after exposure to 4100K FL has not been reported, despite common use of this FL source for residential, commercial, and animal facility illumination. Here, we compare RNASeq results analyzed to assess changes in the global transcription profiles of female and male X. maculatus skin in response to 4100K FL exposure. Our results suggest 4100K FL exposure incites a sex-biased genetic response including up-modulation of inflammation in females and down modulation of DNA repair/replication in males. In addition, we identify clusters of genes that become oppositely modulated in males and females after FL exposure that are principally involved in cell death and cell proliferation.

Title (up) Exposure to low or high light intensity affects pituitary-testicular activity in the fish Oreochromis mossambicus Type Journal Article
Year 2018 Publication Aquaculture Abbreviated Journal Aquaculture
Volume 497 Issue Pages 109-116
Keywords Animals
Abstract Light is an important factor for the successful reproduction of most fish. In this investigation, effect of different light intensities on pituitary-testis axis was studied for a period of 21 days, under normal photoperiodic regime in the tilapia Oreochromis mossambicus. The mean numbers of spermatogonia (Sg), primary spermatocytes (Ps), secondary spermatocytes (Ss), early spermatids (Est) and late spermatids (Lst) did not show significant difference between fish exposed to moderate light intensity (MLI) and initial controls or controls, whereas the mean numbers of Sg were significantly lower in fish exposed to low light intensity (LLI) compared to those of initial controls, controls and MLI groups. However, the mean numbers of Ps, Ss, Est and Lst were significantly lower in fish exposed to LLI and high light intensity (HLI) compared to those of other experimental groups. Furthermore, in the pituitary gland, weakly immunoreactive luteinizing hormone (LH) secreting cells were observed in the proximal pars distalis (PPD) region in fish exposed to LLI and HLI in contrast to the intense immunolabelling of these cells in initial controls, controls and MLI groups. The androgen receptors showed diminished immunoreactivity in the Sertoli cells along the seminiferous lobules of the testis in fish exposed to LLI and HLI, whereas the strongly immunoreactive androgen receptors were observed in the Sertoli cells in initial controls, controls and MLI groups. Taken together, these results indicate that long-term exposure to low or high light intensity light suppresses spermatogenetic process and that this inhibition is due to reduced secretory activity of LH cells in the pituitary gland and androgen secretion in the testis of the fish O. mossambicus.

Title (up) Factors influencing Manx Shearwater grounding on the west coast of Scotland Type Journal Article
Year 2018 Publication Ibis Abbreviated Journal Ibis
Volume 160 Issue 4 Pages 846-854
Keywords Animals
Abstract Grounding of thousands of newly fledged petrels and shearwaters (family Procellariidae) in built‐up areas due to artificial light is a global problem. Due to their anatomy these grounded birds find it difficult to take off from built‐up areas and many fall victim to predation, cars, dehydration or starvation. This research investigated a combination of several factors that may influence the number of Manx Shearwater Puffinus puffinus groundings in a coastal village of Scotland located close to a nesting site for this species. A model was developed that used meteorological variables and moon cycle to predict the daily quantity of birds that were recovered on the ground. The model, explaining 46.32% of the variance of the data, revealed how new moon and strong onshore winds influence grounding. To a lesser extent, visibility conditions can also have an effect on grounding probabilities. The analysis presented in this study can improve rescue campaigns of not only Manx Shearwaters but also other species attracted to the light pollution by predicting conditions leading to an increase in the number of groundings. It could also inform local authorities when artificial light intensity needs to be reduced.
