Title Effect of light quality on movement of Pterostichus melanarius (Coleoptera: Carabidae) Type Journal Article
Year 2012 Publication Journal of Applied Entomology Abbreviated Journal
Volume 136 Issue 10 Pages 793–800
Keywords Animals; insects; movement activity; movement behaviour; movement speed; red light sensitivity; resting behaviour
Abstract Behaviour of nocturnal insects is routinely observed under red light, but it is unclear how the behaviour under red light compares to behaviour in complete darkness, or under a source of white light. Here, we measure movement behaviour of the nocturnal carabid beetle Pterostichus melanarius Illiger (Coleoptera: Carabidae) using camera recording under a near-infrared (nir), red or white radiation source. Red light significantly reduced movement speed in females similar to the effect of white light and different from nir. Also movement activity and pause length were affected by radiation source, with a significant difference between nir and white light, and with intermediate values in red light. The results presented here indicate that P. melanarius has different movement behaviour under the three radiation sources and suggest that nir rather than red radiation is most appropriate for measuring behaviour in total darkness. However, in the field total darkness is rare both because of natural light sources such as the moon and stars but increasingly also because of ecological light pollution, and therefore red light may still be of use for observing ecologically and practically relevant natural night-time behaviour.

Title Enhanced oil spill detection sensors in low-light environments Type Conference Article
Year 2016 Publication Proc. SPIE 9827, Ocean Sensing and Monitoring VIII, 98270B (May 17, 2016) Abbreviated Journal Proc. SPIE 9827
Volume Issue Pages
Keywords Instrumentation; Sensors; Cameras; Long wavelength infrared; Short wave infrared radiation; Spectroscopy; Calibration; Remote sensing; Water; Near infrared; Night vision
Abstract Although advances have been made in oil spill remote detection, many electro-optic sensors do not provide real-time images, do not work well under degraded visual environments, nor provide a measure of extreme oil thickness in marine environments. A joint program now exists between BSEE and NVESD that addresses these capability gaps in remote sensing of oil spills. Laboratory experiments, calibration techniques, and field tests were performed at Fort Belvoir, Virginia; Santa Barbara, California; and the Ohmsett Test Facility in Leonardo, New Jersey. Weathered crude oils were studied spectroscopically and characterized with LWIR, and low-light-level visible/NIR, and SWIR cameras. We designed and fabricated an oil emulsion thickness calibration cell for spectroscopic analysis and ground truth, field measurements. Digital night vision cameras provided real-time, wide-dynamic-range imagery, and were able to detect and recognize oil from full sun to partial moon light. The LWIR camera provided quantitative oil analysis (identification) for >1 mm thick crude oils both day and night. Two filtered, co-registered, SWIR cameras were used to determine whether oil thickness could be measured in real time. Spectroscopic results revealed that oil emulsions vary with location and weathered state and some oils (e.g., ANS and Santa Barbara seeps) do not show the spectral rich features from archived Deep Water Horizon hyperspectral data. Multi-sensor imagery collected during the 2015 USCG Airborne Oil Spill Remote Sensing and Reporting Exercise and the design of a compact, multiband imager are discussed.

Title Impact of a shift work-like lighting schedule on the functioning of the circadian system in the short-lived fish Nothobranchius furzeri Type Journal Article
Year 2018 Publication Experimental Gerontology Abbreviated Journal Exp Gerontol
Volume in press Issue Pages in press
Keywords Animals
Abstract Adult Nothobranchius furzeri of the MZM-04/10 strain were individually kept and subjected to a “5+2” shifting lighting schedule (SHIFT) for 8weeks in order to evaluate the desynchronizing effects of a simulated human-like shift-work schedule on the functioning of the circadian system (CS). With this aim, sixteen 21-week-old N. furzeri were placed into a Morning, Night and Evening schedule (lights on from 08:00 to 16:00, 00:00 to 08:00 and 16:00 to 00:00h, respectively) and fed once a day in the middle of the corresponding photophase (12:00, 04:00 and 20:00h, respectively). Then, in the weekends (2days), fish were always returned to the Morning shift. As controls, 16 fish were maintained under a non-shifting LD cycle condition (CONTROL) throughout the whole experiment, with lights on from 08:00 to 16:00h. Rest-activity rhythm (RAR) of fish subjected to SHIFT showed several symptoms of chronodisruption, such as a decrease in the percentage of diurnal activity and a reduction of the relative amplitude and the circadian function index with time. When a periodogram analysis was performed, RAR of N. furzeri under SHIFT conditions showed up to three separate circadian components: one longer than 24h (26.5h) that followed the weekly 8h delays; a short-period component (~23h) that was related to the weekend's phase advances, and finally, a 24h component. The shifting LD schedule also affected fish CS at a molecular level, with several significant differences in the expression of core genes of the molecular clock (bmal1, clock, roralpha, rev-erbalpha) between SHIFT and CONTROL animals. RAR impairment along with changes in clock gene expression could be associated with high stress and accelerated aging in these fish.

Title How can planning for sustainability improve Costa de Caparica's nightlife? Type Journal Article
Year 2012 Publication International Journal of Urban Sustainable Development Abbreviated Journal International Journal of Urban Sustainable Development
Volume 4 Issue 1 Pages 111-123
Keywords Economics
Abstract In the twentieth century, several transformations occurred in the way society used and perceived urban lighting. This allowed the growth of leisure and other activities related to free time and culture into the night period. Night gained an increasing importance among urban policies and therefore required to be framed within these complex urban contexts as well as other planning processes. This article addresses the Polis Program and its contribution to the improvement of Costa de Caparica's nightlife. It aims to analyse the urban renewal intervention of the Polis Program at Costa de Caparica in terms of night economy and sustainability concerns, in light of Egan's sustainable communities' components. The argument is that the planning of night can contribute to the construction of a sustainable community. The main conclusions focus on the importance that should have been given to governance, public participation and equity components of Egan's wheel along the implementation of the programme, as well as in planning processes broadly, towards achieving a sustainable nightlife.

Title Reduced flight-to-light behaviour of moth populations exposed to long-term urban light pollution Type Journal Article
Year 2016 Publication Biology Letters Abbreviated Journal Biol Lett
Volume 12 Issue 4 Pages 20160111
Keywords Lepidoptera; Yponomeuta; adaptation; environmental change; natural selection
Abstract The globally increasing light pollution is a well-recognized threat to ecosystems, with negative effects on human, animal and plant wellbeing. The most well-known and widely documented consequence of light pollution is the generally fatal attraction of nocturnal insects to artificial light sources. However, the evolutionary consequences are unknown. Here we report that moth populations from urban areas with high, globally relevant levels of light pollution over several decades show a significantly reduced flight-to-light behaviour compared with populations of the same species from pristine dark-sky habitats. Using a common garden setting, we reared moths from 10 different populations from early-instar larvae and experimentally compared their flight-to-light behaviour under standardized conditions. Moths from urban populations had a significant reduction in the flight-to-light behaviour compared with pristine populations. The reduced attraction to light sources of 'city moths' may directly increase these individuals' survival and reproduction. We anticipate that it comes with a reduced mobility, which negatively affects foraging as well as colonization ability. As nocturnal insects are of eminent significance as pollinators and the primary food source of many vertebrates, an evolutionary change of the flight-to-light behaviour thereby potentially cascades across species interaction networks.
