Title Perspectives and challenges for the use of radar in biological conservation Type Journal Article
Year 2018 Publication Ecography Abbreviated Journal Ecography
Volume in press Issue Pages
Keywords Animals; Review
Abstract Radar is at the forefront for the study of broad‐scale aerial movements of birds, bats and insects and related issues in biological conservation. Radar techniques are especially useful for investigating species which fly at high altitudes, in darkness, or which are too small for applying electronic tags. Here, we present an overview of radar applications in biological conservation and highlight its future possibilities. Depending on the type of radar, information can be gathered on local‐ to continental‐scale movements of airborne organisms and their behaviour. Such data can quantify flyway usage, biomass and nutrient transport (bioflow), population sizes, dynamics and distributions, times and dimensions of movements, areas and times of mass emergence and swarming, habitat use and activity ranges. Radar also captures behavioural responses to anthropogenic disturbances, artificial light and man‐made structures. Weather surveillance and other long‐range radar networks allow spatially broad overviews of important stopover areas, songbird mass roosts and emergences from bat caves. Mobile radars, including repurposed marine radars and commercially dedicated ‘bird radars’, offer the ability to track and monitor the local movements of individuals or groups of flying animals. Harmonic radar techniques have been used for tracking short‐range movements of insects and other small animals of conservation interest. However, a major challenge in aeroecology is determining the taxonomic identity of the targets, which often requires ancillary data obtained from other methods. Radar data have become a global source of information on ecosystem structure, composition, services and function and will play an increasing role in the monitoring and conservation of flying animals and threatened habitats worldwide.

Title Electric Lighting Policy in the Federal Government, 1880-2016 Type Journal Article
Year 2018 Publication Abbreviated Journal
Volume Issue Pages
Keywords History; Policy; Lighting
Abstract Federal policies have targeted electric lighting since the 1880s with varying success. This dissertation examines the history of those policies to understand policy makers’ intent and how their decisions affected the course of events. This qualitative study poses three research questions: How have changes in lamp efficacy affected policy development? How and why have federal policies targeted electric lighting? How have private sector actors adapted public policy to further their own goals? The analysis uses an interdisciplinary approach taking advantage of overlapping methodologies drawn from policy and political sciences, economics, and the history of technology. The concepts of path dependency, context, and actor networks are especially important. Adoption of electric lighting spurred the construction of complex and capital intensive infrastructures now considered indispensable, and lighting always consumed a significant fraction of US electric power. Engineers and scientists created many lamps over the decades, in part to meet a growing demand for energy efficient products. Invention and diffusion of those lamps occurred amid changing standards and definitions of efficiency, shifting relations between network actors, and the development of path dependencies that constrained efforts to affect change. Federal actors typically used lighting policy to conserve resources, promote national security, or to symbolically emphasize the onset of a national crisis. The study shows that after an initial introductory phase, lighting-specific policies developed during two distinct periods. The earlier period consisted of intermittent, crisis-driven federal interventions of mixed success. The later period featured a sustained engagement between public and private sectors wherein incremental adjustments achieved policy goals. A time of transition occurred between the two main periods during which technical, economic, and political contexts changed, while several core social values remained constant. In both early and later periods, private sector actors used policy opportunities to further commercial goals, a practice that public sector actors in the later period used to promote policy acceptance. Recently enacted energy standards removing ordinary incandescent lamps in favor of high efficiency lamps mark the end of the later period. Apparent success means that policy makers should reconsider how they use lighting to achieve future goals.

Title Quantifying the attractiveness of broad-spectrum street lights to aerial nocturnal insects Type Journal Article
Year 2018 Publication Journal of Applied Ecology Abbreviated Journal J Appl Ecol
Volume 55 Issue 2 Pages 714-722
Keywords Animals
Abstract Sodium street lights, dominated by long wavelengths of light, are being replaced by broad‐spectrum, white lights globally, in particular light‐emitting diodes (LEDs). These white lights typically require less energy to operate and are therefore considered “eco‐friendly”. However, little attention has been paid to the impacts white lights may have upon local wildlife populations.

We compared insect attraction to orange (high‐pressure sodium, HPS) and white (metal halide, MH and LED) street lights experimentally using portable street lights and custom‐made flight intercept traps.

Significantly more (greater than five times as many) insects were attracted to white MH street lights than white (4,250 K) LED and HPS lights. There was no statistical difference in the numbers of insects attracted to LED and HPS lights for most taxa caught. However, rarefaction shows a greater diversity of insects caught at LED than HPS lights.

Policy implications. With the current, large‐scale conversion to white light‐emitting diode (LED) lighting, our results give insight into how changes to street light technology may affect wildlife populations and communities. We recommend avoiding metal halide light installations as they attract many more insects than competing technologies. We highlight the need to tailor LED lighting to prevent disturbances across multiple insect taxa.

Title The Value of Darkness: A Moral Framework for Urban Nighttime Lighting Type Journal Article
Year 2018 Publication Science and Engineering Ethics Abbreviated Journal Sci Eng Ethics
Volume 24 Issue 2 Pages 607-628
Keywords Darkness; Society
Abstract The adverse effects of artificial nighttime lighting, known as light pollution, are emerging as an important environmental issue. To address these effects, current scientific research focuses mainly on identifying what is bad or undesirable about certain types and uses of lighting at night. This paper adopts a value-sensitive approach, focusing instead on what is good about darkness at night. In doing so, it offers a first comprehensive analysis of the environmental value of darkness at night from within applied ethics. A design for values orientation is utilized to conceptualize, define, and categorize the ways in which value is derived from darkness. Nine values are identified and categorized via their type of good, temporal outlook, and spatial characteristics. Furthermore, these nine values are translated into prima facie moral obligations that should be incorporated into future design choices, policy-making, and innovations to nighttime lighting. Thus, the value of darkness is analyzed with the practical goal of informing future decision-making about urban nighttime lighting.

Title Roadway Lighting’s Impact on Altering Soybean Growth – Volume 2: LED versus HPS Color Spectral Impact Type Journal Article
Year 2018 Publication Technical Report Abbreviated Journal
Volume FHWA-ICT-18-009 Issue Pages
Keywords Plants
Abstract The impact of roadway lighting on soybean plant growth and development, was measured in situ at three locations in the state of Illinois. These locations were situated in close proximity of each other for the purpose of evaluating whether there was a difference in the soy response to HPS roadway lighting, versus soy lit by a specific model of 4,000K LED roadway lighting. The plant data collection included the reproductive-stage, the plant moisture content, and the dried seed weight after harvest. The impact of the type of roadway lighting on the reproduction stage and normalized yield was within the modeling confidence limits at a level of 90%. Modifications are recommended to the specification for roadway lighting trespass. This will minimize the impact on soybean plants based on the two roadway luminaire designs included in this study.
