Title Shining a new light on the environmental Kuznets curve for CO2 emissions Type Journal Article
Year (down) 2020 Publication Energy Economics Abbreviated Journal Energy Economics
Volume 87 Issue Pages 104704
Keywords Remote Sensing
Abstract This paper examines the existence of an inverted U-shaped relationship between income and CO2 emissions from fossil fuels for a panel of 161 countries over the period 1992–2012. Our contribution, empirical in nature, is threefold. (i) We estimate the Environmental Kuznets Curve for CO2 emissions using three conventional measures of GDP taken from the PWT and the WDI and show that the results of the estimates are unstable and that the turning points are dependent on the measure of GDP. (ii) We use a new dataset of GDP based on the Defense Meteorological Satellite Program's Operational Linescan System (DMSP-OLS) nighttime light imagery as a proxy for the development level, and using these data, which are less prone to the measurement errors in the System of National Accounts statistics, we find evidence for the existence of an Environmental Kuznets Curve for CO2 emissions. (iii) We apply a U test that confirms that the estimated extreme point is within our data range. The evaluated turning point, beyond which CO2 emissions start to fall as income rises, is considerably lower than earlier studies show, and thus, our results provide more optimistic prospects of the possible environmental benefits of economic growth.

Title Cool (blue) vs. warm (yellow) displays enhance visual function Type Journal Article
Year (down) 2020 Publication Eye (London, England) Abbreviated Journal Eye (Lond)
Volume in press Issue Pages
Keywords Human Health
Abstract Displays emitting substantial blue light (phones, tablets, computers) can produce eyestrain (computer vision syndrome: CVS) [1, 2]. Yet findings have been challenged [3]. A metric to assess CVS is the highest detectable flicker rate (CFF). We compared the short-term effects of bluish (“cool”) vs. yellowish (“warm”) displays on high temporal frequency contrast sensitivity (TCS), which relates directly to the CFF.

Title Embracing Their Prey at That Dark Hour: Common Cuttlefish (Sepia officinalis) Can Hunt in Nighttime Light Conditions Type Journal Article
Year (down) 2020 Publication Frontiers in Physiology Abbreviated Journal Front. Physiol.
Volume 11 Issue Pages in press
Keywords Animals
Abstract Cuttlefish are highly efficient predators, which strongly rely on their anterior binocular visual field for hunting and prey capture. Their complex eyes possess adaptations for low light conditions. Recently, it was discovered that they display camouflaging behavior at night, perhaps to avoid detection by predators, or to increase their nighttime hunting success. This raises the question whether cuttlefish are capable of foraging during nighttime. In the present study, prey capture of the common cuttlefish (Sepiaofficinalis) was filmed with a high-speed video camera in different light conditions.Experiments were performed in daylight and with near-infrared light sources in two simulated nightlight conditions, as well as in darkness. The body of the common cuttlefish maintained a velocity of less than 0.1 m/s during prey capture, while the tentacles during the seizing phase reached velocities of up to 2.5 m/s and accelerations reached more than 450 m/s2 for single individuals. There was no significant difference between the day and nighttime trials, respectively. In complete darkness, the common cuttlefish was unable to catch any prey. Our results show that the common cuttlefish are capable of catching prey during day- and nighttime light conditions. The common cuttlefish employ similar sensory motor systems and prey capturing techniques during both day- and nighttime conditions.

Title Improved Usability of Pedestrian Environments After Dark for People with Vision Impairment: an Intervention Study Type Journal Article
Year (down) 2020 Publication Sustainability Abbreviated Journal Sustainability
Volume 12 Issue 3 Pages 1096
Keywords Vision
Abstract Walking is an important transport mode for sustainable cities, but the usability of pedestrian environments for people with impaired vision is very limited after dark. This study compares the usability of a walkway, operationalized in terms of (i) the pedestrian’s ability to orient themselves and detect infrastructure elements, and (ii) the perceived quality of lighting in the environment (evaluated in terms of the perceived strength quality and perceived comfort quality). The study was performed in a city in southern Sweden, along a pedestrian route where observations and structured interviews had previously been conducted and after an intervention involving installing new lighting systems with LED lights. A mixed method analysis involving participants with impaired vision (N=14) showed that the intervention generally improved the walkway’s usability: observations indicated that the participants’ ability to orientate themselves and detect infrastructure elements increased, and the interviews showed that the intervention increased the perceived strength quality of the lighting along the walkway. However, the effects on the perceived comfort quality were unclear. It is therefore important to carefully evaluate new lighting systems to reduce the risk of creating an inappropriate lighting design that will limit walking after dark by people with impaired vision.

Title Dramatic decline of northern bat Eptesicus nilssonii in Sweden over 30 years Type Journal Article
Year (down) 2020 Publication Royal Society Open Science Abbreviated Journal R Soc Open Sci
Volume 7 Issue 2 Pages 191754
Keywords Animals; Lepidoptera; climate change; light pollution; line transects; long-term monitoring; population decline
Abstract We monitored northern bat Eptesicus nilssonii (Keyserling & Blasius, 1839) acoustically along a 27 km road transect at weekly intervals in 1988, 1989 and 1990, and again in 2016 and 2017. The methodology of data collection and the transect were the same throughout, except that the insect-attracting mercury-vapour street-lights along parts of the road were replaced by sodium lights between the two survey periods. Counts along sections of the transect with and without street-lights were analysed separately. The frequency of bat encounters in unlit sections showed an average decline of 3.0% per year, corresponding to a reduction of 59% between 1988 and 2017. Sections with street-lights showed an 85% decline over the same period (6.3% per year). The decline represents a real reduction in the abundance of bats rather than an artefact of changed distribution of bats away from roads. Our study conforms with another long-term survey of the same species on the Baltic island of Gotland. Our results agree with predictions based on climate change models. They also indicate that the decline was caused directly by the disuse of the insect-attracting mercury-vapour street-lights, which may have resulted in lower availability of preferred prey (moths). In the 1980s, E. nilssonii was considered the most common bat in Sweden, but the subsequent decline would rather qualify it for vulnerable or endangered status in the national Red List of Threatened Species.
