Title Environmental heterogeneity alters mate choice behavior for multimodal signals Type Journal Article
Year 2019 Publication Behavioral Ecology and Sociobiology Abbreviated Journal Behav Ecol Sociobiol
Volume 73 Issue (up) Pages
Keywords Animals
Abstract nimals frequently experience changes in their environment, including diel and seasonal shifts in abiotic and biotic factors. In addition to physiological and morphological changes, animals alter their behavior in response to environmental variation. This study examined the impacts of heterogeneous environments on mating behaviors. We examined both male and female túngara frog phonotactic responses to multimodal (audiovisual) and unimodal (acoustic) stimuli. We altered aspects of the physical environment by changing substrate (terrestrial and aquatic) and ambient light levels. Females demonstrated a similar preference for the audiovisual stimulus regardless of substrate but decreased latency to choose in an aquatic environment. When ambient light levels were increased (relative to darker control), females reversed their preference, avoiding the multimodal stimulus, but the latency to choose was unchanged. Males demonstrated no preference for the multimodal signal on either substrate, but like females, male latency was reduced in an aquatic environment. Different environments carry their own associated costs, including varying levels of predation risk. Increased light levels and an aquatic environment likely carry higher predation risk and therefore should lead to changes in female and male responses. Interestingly, these two environments do not cause uniform changes in female responses. The addition of an aquatic environment led to a reduction in latency, whereas an increase in ambient light levels induced a change in female mate preference. These findings demonstrate the importance of the environment on mating responses to multimodal signals.

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 (up) 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.

Title No lunar phobia in insectivorous bats in Kenya Type Journal Article
Year 2019 Publication Mammalian Biology Abbreviated Journal Mammalian Biology
Volume 95 Issue (up) Pages 77-84
Keywords Animals
Abstract We monitored foraging insectivorous bats along walked transects in forest and farmland at Arabuko-Sokoke Forest in coastal Kenya, using a heterodyne bat detector. The main purpose was to test whether aerial-hawking insectivorous bats that feed in open places (in this case mostly Scotophilus and Scotoecus spp.) show lunar phobia, i.e. restricting their activity on moonlit nights. Such behavior would be an expected response to the threat posed by visually oriented aerial predators such as bat hawks, owls and carnivorous bats. The occurrence of lunar phobia in bats is a controversial issue and may have implications for how bats will be affected by increasing light pollution. Our results show that foraging activity of the bats that we studied was related to time of day, season, and habitat, albeit with no additional effect of moonlight discernable. We therefore conclude that foraging activity occurs independently of moonlight. This result is partly at odds with previous findings including predictions from a meta-analysis of lunar phobia in bats, which indicates that lunar phobia is common in these animals, though most likely to be present in tropical species that feed in open situations near vegetation and over water. Equally, our results conform to findings from studies of aerial insectivorous bats in tropical as well as temperate areas, most of which have failed to reveal any clear evidence of lunar phobia. We believe that moonlight generally does not facilitate aerial predation on flying bats in open situations, or, alternatively, the bats accept increased predation pressure while they fulfil the energetic requirements through hunting.

Title Using Category Rating to Evaluate the Lit Environment: Is a Meaningful Opinion Captured? Type Journal Article
Year 2018 Publication Leukos Abbreviated Journal Leukos
Volume Issue (up) Pages 1-16
Keywords Psychology
Abstract Do responses gained using category rating accurately reflect respondents’ true evaluations of an item? “True” in this sense means that they have a real opinion about the issue, rather than being compelled by the survey to speculate an opinion, and that the strength of that opinion is faithfully captured. This article describes some common issues that suggest that it should not be simply assumed that a response gained using category rating reflects a true evaluation. That assumption requires an experiment to have been carefully designed and interpreted, and examples are shown where this is not the case. The article offers recommendations for good practice.

Title World Heritage in danger: Big data and remote sensing can help protect sites in conflict zones Type Journal Article
Year 2019 Publication Global Environmental Change Abbreviated Journal Global Environmental Change
Volume 55 Issue (up) Pages 97-104
Keywords Remote Sensing
Abstract World Heritage sites provide a key mechanism for protecting areas of universal importance. However, fifty-four UNESCO sites are currently listed as “In Danger”, with 40% of these located in the Middle East. Since 2010 alone, thirty new sites were identified as under risk globally. We combined big-data and remote sensing to examine whether they can effectively be used to identify danger to World Heritage in near real-time. We found that armed-conflicts substantially threaten both natural- and cultural-heritage listed sites. Other major risks include poor management and development (globally), poaching (Africa mostly) and deforestation (tropics), yet conflict is the most prominent threat. We show that news-mining of big-data on conflicts and remote sensing of nights-lights enabled us to identify conflict afflicted areas in near real-time. These findings provide a crucial avenue for developing a global transparent early-warning system before irreversible damage to world heritage takes place.
