Title Estimation of Landscape Pattern Changes in BRICS from 1992 to 2013 Using DMSP-OLS NTL Images Type Journal Article
Year 2019 Publication Journal of the Indian Society of Remote Sensing Abbreviated Journal
Volume Issue Pages
Keywords Remote Sensing
Abstract Nighttime light data from the Defense Meteorological Satellite Program’s Operational Linescan System are widely used for monitoring urbanization development. Brazil, Russia, India, China and South Africa (BRICS) countries have global economic and cultural influence in the new era. It was the first time for the researches about BRICS countries adopting nighttime light data to analyze the urbanization process. In this paper, we calibrated and extracted annual urbanized area patches from cities in BRICS based on a quadratic polynomial model. Nine landscape indexes were calculated to analyze urbanization process characteristics in BRICS. The results suggested that China and India both expanded more rapidly than other countries, with urban areas that increased by more than 100%. The expansion of large core cities was dominant in the urbanization of China, while emerging and expanding small urban patches were major forces in the urbanization of India. Since 1992, urbanization declined and urban areas shrunk in Russia, but core cities still maintained strength of urbanization. Due to economic recovery, urban areas near large cities in Russia began to expand. From 1992 to 2013, the urbanization process in South Africa developed slowly, as evidenced by time series fluctuations, but overall the development remained stable. The degree of urbanization in Brazil was greater than that in South Africa but less than that in Russia. Large-sized cities expanded slowly and small-sized cities clearly expanded in BRICS from 1992 to 2013.

Title Evidence of Newell’s Shearwaters and Hawaiian Petrels on Oahu, Hawaii Type Journal Article
Year 2019 Publication The Condor: Ornithological Applications Abbreviated Journal
Volume 121 Issue 1 Pages
Keywords Animals; Remote Sensing
Abstract Hawaii’s only 2 endemic seabirds, Newell’s Shearwater (Puffinus auricularis newelli) and Hawaiian Petrel (Pterodroma sandwichensis), are listed under the United States Endangered Species Act. Threats to both species include light attraction and fallout, collisions with power lines and other structures, predation by invasive animals, and habitat degradation. Both species were assumed to be extirpated from the island of Oahu despite limited survey effort. We used survey data from Kauai (both species) and Maui (Hawaiian Petrel only) to model suitable habitat and light conditions. We then projected this model onto Oahu to identify potential survey sites. From April to September of 2016–2017, we deployed automated acoustic recording units at 13 potentially suitable sites across Oahu. We detected Newell’s Shearwaters at 2 sites; one on the leeward slopes of Mount Kaala in the Waianae Mountains and another at Poamoho in the Koolau Mountains. We detected Hawaiian Petrels at one location on the windward slope of Mount Kaala. All 3 sites were in nearly intact native forest with steep slopes. The frequency of detections at these sites suggests that both species are regularly prospecting on Oahu and potentially could be breeding there. If they are breeding, these individuals could represent missing links in the population connectivity of both species among islands. Protecting any remnant breeding populations would be of high conservation value given their recent population declines.

Title Skyglow extends into the world’s Key Biodiversity Areas Type Journal Article
Year 2019 Publication Animal Conservation Abbreviated Journal
Volume Issue Pages
Keywords Skyglow; Conservation
Abstract The proportion of the Earth’s surface that experiences a naturally dark environment at night is rapidly declining with the introduction of artificial light. Biological impacts of this change have been documented from genes to ecosystems, and for a wide diversity of environments and organisms. The likely severity of these impacts depends heavily on the relationship between the distribution of artificial night-time lighting and biodiversity. Here, we carry out a global assessment of the overlap between areas of conservation priority and the most recent atlas of artificial skyglow. We show that of the world’s Key Biodiversity Areas (KBAs), less than a third have completely pristine night-time skies, about a half lie entirely under artificially bright skies and only about a fifth contain no area in which night-time skies are not polluted to the zenith. The extent of light pollution of KBAs varies by region, affecting the greatest proportion of KBAs in Europe and the Middle East. Statistical modelling revealed associations between light pollution within KBAs and associated levels of both gross domestic product and human population density. This suggests that these patterns will worsen with continued economic development and growth in the human population

Title The impact of artificial light at night (ALAN) on the National Nature Parks, Biosphere and Naturе Reserves of the Steppe Zone and Crimean Mountains within Ukraine Type Journal Article
Year 2018 Publication Palaearctic Grasslands Abbreviated Journal
Volume Issue Pages
Keywords Skyglow; Conservation
Abstract Artificial light at night (ALAN) and sky glow are a recognized anthropogenic pressure, but the consequences of this pressure on protected areas within Ukraine are unclear. This research attempted to estimate the level of light pollution on the protected territories of the National Nature Parks (NNPs), Biosphere and Nature Reserves in the Steppe Zone and Crimea Mountains of Ukraine. Kmz layers of

these protected territories and the New World Atlas of Artificial Sky Brightness, through Google Earth Pro, were used to calculate the level of artificial sky brightness for 15 NNPs, three Biosphere Reserves and 10 Nature Reserves. The results show that even some of the most protected areas within the Steppe Zone and Crimean Mountains are impacted by ALAN. Of the studied protected areas 44.2% have a natural dark night sky, 40.1% have artificial brightness ranging between 8 and 16%, and the remainder (15.7%) are polluted with an artificial brightness greater than 16%. Areas with light pollution greater than 16% are often situated near big cities or industrial centers. It was noted that light pollution levels were not taken into account during the creation of any protected areas within Ukraine.

Title Impact of artificial lights on foraging of insectivorous bats in a Costa Rican cloud forest Type Journal Article
Year 2019 Publication Journal of Tropical Ecology Abbreviated Journal
Volume 35 Issue 1 Pages 8-17
Keywords Animals
Abstract Determining the effects of light pollution on tropical bat communities is important for understanding community assembly rules in urban areas. Studies from temperate regions suggest that, among aerial insectivorous bats, fast-flying species that forage in the open are attracted to artificial lights, whereas slow-flying species that forage in cluttered environments avoid those lights. We measured aerial insectivore responses to light pollution in a tropical cloud forest to test this hypothesis. Bat echolocation was recorded at 20 pairs of light and dark sites in Monteverde, Costa Rica. Foraging activity was higher at artificially lighted sites than dark sites near the new moon, especially around blue-white fluorescent lighting. Most recorded bat species showed increased or unchanged activity in response to light, including some slow-flying and edge-foraging bats. This finding suggests that, contrary to the evaluated hypothesis, flight speed and foraging mode are not sufficient to determine bat responses to artificial lights in the tropics. Two bat species showed decreased activity at light sites, and a low species evenness was recorded around lights, particularly fluorescent lights, compared with dark sites. As in the temperate zone, light pollution in the tropics seems to concentrate certain bat species around human-inhabited areas, potentially shifting community structure.
