  Title The effect of artificial light at night on the biomass of caterpillars feeding in urban tree canopies Type Journal Article
  Year 2020 Publication Urban Ecosystems Abbreviated Journal  
  Volume in press Issue Pages  
  Keywords Animals  
  Abstract Alternation of day and night is the oldest cycle on Earth, which is increasingly disturbed by the accelerating rate of urbanization and technological development. Despite the ubiquity of light pollution in cities, many aspects of its influence on urban ecosystems are still poorly understood. Here we studied the effect of artificial light at night (ALAN) on the biomass of arboreal caterpillar populations, which are a major component of the diet of many insectivorous animals. We predicted that increasing ALAN intensity is associated with reduced caterpillar biomass, because ALAN may increase predation risk for both caterpillars and adult lepidopterans (i.e. moths), and can also hinder the moths’ reproductive rate. We estimated caterpillar biomass from frass samples (n = 3061) collected from 36 focal trees in two cities in Hungary during four consecutive years. To quantify ALAN we measured light intensity during night at each focal tree (range of illumination: 0.69–3.18 lx). We found that caterpillar biomass of individual trees was repeatable over the four years. This temporal consistency in prey biomass production may be important for birds because it can help predict territory quality, especially in cities where caterpillar abundance is generally low. Our results did not support the negative effect of ALAN on urban caterpillar populations, because ALAN intensity was not related to caterpillar biomass, and this lack of effect was consistent between study sites and tree species. We suggest that the effect of ALAN on urban caterpillar biomass is either weak and thus can be masked by other, local environmental factors, or light pollution may have antagonistic effects acting during different stages of the lepidopteran life cycle. Another explanation could be that even the lower levels of our sites’ public lighting are strong enough to cause serious detrimental effects for caterpillars, resulting in their uniformly low biomass.

  Title The relationship between anthropogenic light and noise in U.S. national parks Type Journal Article
  Year 2020 Publication Landscape Ecology Abbreviated Journal Landscape Ecol  
  Volume 35 Issue 6 Pages 1371-1384  
  Keywords Remote Sensing; Conservation; Skyglow  
  Abstract Context

Natural sound and light regulate fundamental biological processes and are central to visitor experience in protected areas. As such, anthropogenic light and noise have negative effects on both wildlife and humans. While prior studies have examined the distribution and levels of light or noise, joint analyses are rarely undertaken despite their potentially cumulative effects.

Objectives

We examine the relationship between different types of anthropogenic light and noise conditions and what factors drive correlation, co-occurrences, and divergence between them.

Methods

We overlaid existing geospatial models of anthropogenic light and noise with landscape predictors in national parks across the continental U.S.

Results

Overlapping dark and quiet were the most common conditions (82.5–87.1% of park area), representing important refuges for wildlife and human experience. We found low correlation between anthropogenic light and noise (Spearman’s R < 0.25), with the exception of parks with a higher density of roads. Park land within urban areas had the highest probability of co-occurring high light and noise exposure, while park areas with divergent light and noise exposure (e.g., high light and low noise) were most commonly found 5–20 km from urban areas and in parks with roads present.

Conclusions

These analyses demonstrate that light and noise exposure are not always correlated in national parks, which was unexpected because human activities tend to produce both simultaneously. As such, mitigation efforts for anthropogenic light and noise will require efforts targeting site-specific sources of noise and light. Protecting and restoring sensory environments will involve constructive partnerships capable of reconciling diverse community interests.

  Title People and Pixels 20 years later: the current data landscape and research trends blending population and environmental data Type Journal Article
  Year 2019 Publication Population and Environment Abbreviated Journal Popul Environ  
  Volume 41 Issue 2 Pages 209-234  
  Keywords Remote Sensing  
  Abstract In 1998, the National Research Council published People and Pixels: Linking Remote Sensing and Social Science. The volume focused on emerging research linking changes in human populations and land use/land cover to shed light on issues of sustainability, human livelihoods, and conservation, and led to practical innovations in agricultural planning, hazard impact analysis, and drought monitoring. Since then, new research opportunities have emerged thanks to the growing variety of remotely sensed data sources, an increasing array of georeferenced social science data, including data from mobile devices, and access to powerful computation cyberinfrastructure. In this article, we outline the key extensions of the People and Pixels foundation since 1998 and highlight several breakthroughs in research on human–environment interactions. We also identify pressing research problems—disaster, famine, drought, war, poverty, climate change—and explore how interdisciplinary approaches integrating people and pixels are being used to address them.

  Title Can we Rely on VIIRS Nightlights to Estimate the Short-Term Impacts of Natural Disasters? Type Journal Article
  Year 2019 Publication Policy Research Working Papers 9052 Abbreviated Journal  
  Volume Issue Pages  
  Keywords Remote Sensing  
  Abstract Visible Infrared Imaging Radiometer Suite (VIIRS) nightlights are used to model damage caused by earthquakes, floods, and typhoons in five Southeast Asian countries (Indonesia, Myanmar, the Philippines, Thailand, and Vietnam). The data are used to examine the extent to which for each type of hazard there is a difference in nightlight intensity between affected and nonaffected cells based on (i) case studies of specific disasters, and (ii) fixed effect regression models akin to the double difference method to determine any effect that the different natural hazards might have had on the nightlight value. The results show little to no significance regardless of the methodology used, most likely due to noise in the nightlight data and the fact that the tropics have only a few days per month with no cloud cover.

  Title Islamic University of Gaza Students’ Opinions on the Light Pollution Effects on Human Type Journal Article
  Year 2019 Publication European Journal of Physics Education Abbreviated Journal  
  Volume 10 Issue 4 Pages 42-54  
  Keywords Education  
  Abstract Light pollution is nowadays well known all over the world and may negatively cause disturbance to human and have diverse effects. This study aims to identify the views and opinions of the Islamic University of Gaza students on light pollution and then to create awareness among them about the risky problem facing rapidly our society. The study is based on the survey questions and semi-structured interviews and then the data is collected from the survey questions and semi-structured interviews were qualitatively analyzed and quotes from the students' statements were included. Most of the students recognized that excessive lighting can adversely affect a person's health. The results also show that 40.0% of the students feel that the area outside of their residence is at night is “Fair Brightness “, 29.2% “Bright as day “, 13.8% “Pitch Black “, and 16.9% “A Little Black “. 90.8% of the sample are familiar with light pollution, but 9.2% is not. Some suggestions and recommendations will be made for controlling and reducing light pollution to have a healthy society.
