Title Astrotourism–Exceeding Limits of the Earth and Tourism Definitions? Type Journal Article
Year 2021 Publication Sustainability Abbreviated Journal Sustainability
Volume 13 Issue 1 Pages 373
Keywords Astrotourism
Abstract Emerging forms of alternative or even niche tourism represent a dynamic trend in tourism development. Astrotourism is completely off the beaten path. The aim of this study is to provide a deeper insight into this phenomenon. It strives to reveal motivations, experiences, and perceptions of its participants. It also aspires to propose its complex definition as an activity including both terrestrial astrotourism and space tourism. It is suggested to perceive it not only as a form of alternative and/or niche tourism, but also that of mass and professional tourism. To reach these objectives, the authors analyzed relevant published studies and astrotourism products presented on relevant websites and social media. They elaborated the collected secondary data by mental mapping and the comparative analysis of terrestrial and space tourism products. Moreover, the authors collected primary data through a survey with open-ended questions addressed to persons interested in astrotourism and through semi-structured interviews with terrestrial astrotourism participants and personalities. The results provide insight into both the specifity and variability of astrotourism and their typical products, as well as a discussion of their future trends. They also bring a motivation spectrum for the astrotourism participants and benefits perceived by them.

Title Light at night reduces digestive efficiency of developing birds: an experiment with king quail Type Journal Article
Year 2021 Publication Die Naturwissenschaften Abbreviated Journal Naturwissenschaften
Volume 108 Issue 1 Pages 4
Keywords Animals; Avian; Development; Digestion; Excalfactoria chinensis; Light pollution; Steatocrit
Abstract Artificial light at night (ALAN) exposes animals to a novel environmental stimulus, one that is generally thought to be maladaptive. ALAN-related health problems have received little attention in non-model species, and we generally know little about the nutritional-physiological impacts of ALAN, especially in young animals. Here, we use a novel application of the acid steatocrit method to experimentally assess changes in digestive efficiency of growing king quail (Excalfactoria chinensis) in response to ALAN. Two weeks after hatching, quail were split into two groups (n = 20-21 per group): overnight-light-treated vs. overnight-dark-treated. When the chicks were 3 weeks old, the experimental group was exposed to weak blue light (ca. 0.3 lux) throughout the entire night for 6 consecutive weeks, until all the chicks had achieved sexual maturation. Fecal samples for assessing digestive efficiency were collected every week. We found that digestive efficiency of quail was reduced by ALAN at two time points from weeks 4 to 9 after hatching (quail reach adulthood by week 9). The negative effect of ALAN on digestion coincided with the period of fastest skeletal growth, which suggests that ALAN may reduce digestive efficiency when energetic demands of growth are at their highest. Interestingly, growth rate was not influenced by ALAN. This suggests that either the negative physiological impacts of ALAN may be concealed when food is provided ad libitum, the observed changes in digestive efficiency were too small to affect growth or condition, or that ALAN-exposed birds had reduced energy expenditure. Our results illustrate that the health impacts of ALAN on wild animals should not be restricted to traditional markers like body mass or growth rate, but instead on a wide array of integrated physiological traits.

Title When night never falls: female sexual signalling in a nocturnal insect along a latitudinal gradient Type Journal Article
Year 2020 Publication Behavioral Ecology and Sociobiology Abbreviated Journal Behav Ecol Sociobiol
Volume 74 Issue 12 Pages
Keywords Animals; Natural night
Abstract The environment can play an important role in animal communication by affecting signal transmission and detection. Variation in the signalling environment is expected to be especially pronounced in widely distributed species, potentially affecting how their signals are detected. Such environmental variability is presumably relevant for sedentary females of a nocturnal capital breeder, the European common glow-worm (Lampyris noctiluca), which produce green light during the night to attract flying males to mate. Being widely distributed in Europe, glow-worm populations are exposed to both rapidly descending, darker summer nights in the south, and slowly dimming, brighter summer nights further north, with the latter potentially posing challenges to the visibility of the female glow. To test how female signalling is affected by latitude, we sampled glowing females during summer nights along a latitudinal gradient in Finland, Northern Europe, and used a novel apparatus to measure the intensity and peak wavelength (hue/colour) of their glow. Surprisingly, females at higher latitudes, similar to those at lower latitudes, were commonly glowing during the brightest (and hence the shortest) nights of the year. Females also glowed brighter in more northern areas, partly due to their larger body size, whereas the colour of their glow was not associated with latitude. Since females glow even during midsummer, independent of latitude, the increase in glow intensity at higher latitudes presumably serves to maintain signal visibility in brighter signalling conditions. Overall, these findings highlight the influence of environmental conditions on the evolution of sexual signals, especially in the context of species distribution range.

Title Shiftwork and Light at Night Negatively Impact Molecular and Endocrine Timekeeping in the Female Reproductive Axis in Humans and Rodents Type Journal Article
Year 2020 Publication International Journal of Molecular Sciences Abbreviated Journal Int J Mol Sci
Volume 22 Issue 1 Pages
Keywords Review; Human Health; Animals; birth; circadian disruption; estrous cycles; fertility; infertility; menstrual cycles; pregnancy; rodent; shiftwork; women
Abstract Shiftwork, including work that takes place at night (nightshift) and/or rotates between day and nightshifts, plays an important role in our society, but is associated with decreased health, including reproductive dysfunction. One key factor in shiftwork, exposure to light at night, has been identified as a likely contributor to the underlying health risks associated with shiftwork. Light at night disrupts the behavioral and molecular circadian timekeeping system, which is important for coordinated timing of physiological processes, causing mistimed hormone release and impaired physiological functions. This review focuses on the impact of shiftwork on reproductive function and pregnancy in women and laboratory rodents and potential underlying molecular mechanisms. We summarize the negative impact of shiftwork on female fertility and compare these findings to studies in rodent models of light shifts. Light-shift rodent models recapitulate several aspects of reproductive dysfunction found in shift workers, and their comparison with human studies can enable a deeper understanding of physiological and hormonal responses to light shifts and the underlying molecular mechanisms that may lead to reproductive disruption in human shift workers. The contributions of human and rodent studies are essential to identify the origins of impaired fertility in women employed in shiftwork.

Title Detecting the Dynamics of Urban Growth in Africa Using DMSP/OLS Nighttime Light Data Type Journal Article
Year 2021 Publication Land Abbreviated Journal Land
Volume 10 Issue 1 Pages 13
Keywords Remote Sensing
Abstract Africa has been experiencing a rapid urbanization process, which may lead to an increase in unsustainable land use and urban poverty. Assessing the spatiotemporal characteristics of urbanization dynamics is especially important and needed for the sustainable development of Africa. Satellite-based nighttime light (NTL) data are widely used to monitor the dynamics of urban growth from global to local scales. In this study, urban growth patterns across Africa were analyzed and discussed using stable nighttime light datasets obtained from DMSP/OLS (the Defense Meteorological Satellite Program’s Operational Line-scan System) spanning from 1992 to 2013. We partitioned the nighttime lighting areas into three types (low, medium, and high) using thresholds derived from the Brightness Gradient (BG) method. Our results indicated that built-up areas in Africa have increased rapidly, particularly those areas with low nighttime lighting types. Countries with higher urbanization levels in Africa, like South Africa, Algeria, Egypt, Nigeria, and Libya, were leading the brightening trend. The distribution of nighttime lighting types was consistent with the characteristics of urban development, with high nighttime lighting types showed up at the urban center, whereas medium and low nighttime lighting types appeared in the urban-rural transition zone and rural areas respectively. The impacts of these findings on the future of African cities will be further proposed.
