Title Better in the dark: two Mediterranean amphibians synchronize reproduction with moonlit nights Type Journal Article
Year 2013 Publication (down) Web Ecology Abbreviated Journal Web Ecol.
Volume 13 Issue 1 Pages 1-11
Keywords animals; amphibians; Hyla intermedia; Rana dalmatina; *Reproduction; reproductive strategies; Moon; moon phase; moonlight
Abstract In Amphibians, both positive and negative correlations between activity and full moon phase have been observed. In this study, we present data for two anuran species (Hyla intermedia and Rana dalmatina) studied in a hilly Mediterranean area of central Italy. We analysed, in a two-year survey, the relationships between the number of egg clutches laid each night and the moon phases by means of circular statistics. Moreover, the studied species exhibited clear oviposition site selection behaviour influenced, at least in H. intermedia, by moon phases. We observed the occurrence of an avoidance effect by amphibians for oviposition and specific egg-laying behaviour during moon phases around the full moon. This apparent lunar phobia was evident in both species when yearly data were pooled. On the other hand, while this pattern continued to be also evident in H. intermedia when single years were considered, in R. dalmatina it stood just in one year of study. Nonetheless, during cloudy nights, when moonlight arriving on the ground was low, the frogs' behaviour was similar to that observed in new moon phases. We interpreted the observed pattern as an anti-predatory strategy. Overall, comparisons between our own study and previous research suggest that there was insufficient evidence to establish any unequivocal patterns and that further research in this regard is needed.

Title The Gloomy City: Rethinking the Relationship between Light and Dark Type Journal Article
Year 2013 Publication (down) Urban Studies Abbreviated Journal
Volume 52 Issue 3 Pages 422-438
Keywords Society
Abstract Given geography’s neglect of illuminated and dark space, this paper explores the various qualities of darkness that have contributed to the experience of the city. In recent history, darkness has been conceptualised negatively, for instance, with the ‘dark side’ and the ‘forces of darkness’ conceived as the opposite of that which enlightens and illuminates. Perhaps such metaphors testify to earlier urban conditions in which perils of all sorts lurked in the nocturnal city and doors were closed when darkness fell. Yet modern illumination has transformed nocturnal urban experience, producing cityscapes of regulation, hierarchical selectiveness, consumption, fantasy and imagination. However, this article suggests that the more positive qualities of darkness have been overlooked: the potential for conviviality and intimacy to be fostered in the dark, the aesthetics and atmospherics of darkness and shadow, the possibilities for apprehending the world through other senses and the dismissal of the star-saturated sky.

Title Effects of electronic billboards on driver distraction Type Journal Article
Year 2013 Publication (down) Traffic Injury Prevention Abbreviated Journal Traffic Inj Prev
Volume 14 Issue 5 Pages 469-476
Keywords Adult; Advertising as Topic/*methods; *Attention; Automobile Driving/*psychology; Eye Movements; Humans; Middle Aged; Psychomotor Performance; Sweden; Time Factors
Abstract OBJECTIVE: There is an increase in electronic advertising billboards along major roads, which may cause driver distraction due to the highly conspicuous design of the electronic billboards. Yet limited research on the impact of electronic billboards on driving performance and driver behavior is available. The Swedish Transport Administration recently approved the installation of 12 electronic billboards for a trial period along a 3-lane motorway with heavy traffic running through central Stockholm, Sweden. The aim of this study was to evaluate the effect of these electronic billboards on visual behavior and driving performance. METHOD: A total of 41 drivers were recruited to drive an instrumented vehicle passing 4 of the electronic billboards during day and night conditions. A driver was considered visually distracted when looking at a billboard continuously for more than 2 s or if the driver looked away from the road for a high percentage of time. Dependent variables were eye-tracking measures and driving performance measures. RESULTS: The visual behavior data showed that drivers had a significantly longer dwell time, a greater number of fixations, and longer maximum fixation duration when driving past an electronic billboard compared to other signs on the same road stretches. No differences were found for the factors day/night, and no effect was found for the driving behavior data. CONCLUSION: Electronic billboards have an effect on gaze behavior by attracting more and longer glances than regular traffic signs. Whether the electronic billboards attract too much attention and constitute a traffic safety hazard cannot be answered conclusively based on the present data.
