Title (up) Bedroom Light Exposure at Night and the Incidence of Depressive Symptoms: A Longitudinal Study of the HEIJO-KYO Cohort Type Journal Article
Year 2018 Publication American Journal of Epidemiology Abbreviated Journal Am J Epidemiol
Volume 187 Issue 3 Pages 427-434
Keywords Human Health; Mental Health; indoor light; geriatrics; Sleep; Sleep Disorders
Abstract Previous studies have indicated that minimal exposure to light at night (LAN) increases depression risk, even at 5 lux, in nocturnal and diurnal mammals. Although such low-level LAN may affect human circadian physiology, the association between exposure to LAN and depressive symptoms remains uncertain. In the present study, bedroom light intensity was measured objectively, and depressive symptoms were assessed, during 2010-2014 in Nara, Japan. Of 863 participants (mean age = 71.5 years) who did not have depressive symptoms at baseline, 73 participants reported development of depressive symptoms during follow-up (median, 24 months). Compared with the “dark” group (average of <5 lux; n = 710), the LAN group (average of >/=5 lux; n = 153) exhibited a significantly higher depression risk (hazard ratio = 1.89; 95% CI: 1.13, 3.14), according to a Cox proportional hazards model adjusting for age, sex, body mass index, and economic status. Further, the significance remained in a multivariable model adjusting for hypertension, diabetes, and sleep parameters (hazard ratio = 1.72; 95% CI: 1.03, 2.89). Sensitivity analyses using bedroom light data with a cutoff value of >/=10 lux suggested consistent results. In conclusion, these results indicated that exposure to LAN in home settings was independently associated with subsequent depression risk in an elderly general population.

Title (up) Behavioral Responses of the Invasive Halyomorpha halys (StÃ¥l) (Hemiptera: Pentatomidae) to Light-Based Stimuli in the Laboratory and Field Type Journal Article
Year 2015 Publication Journal of Insect Behavior Abbreviated Journal J. of Insect Behav.
Volume 28 Issue 6 Pages 674-692
Keywords Animals; Brown marmorated stink bug; light trap; visual ecology; IPM; wavelength; Halyomorpha halys; invasive species
Abstract Halyomorpha halys (Stål), brown marmorated stink bug, is an invasive insect native to Asia that was accidentally introduced into the United States. The species is a polyphagous pest that has caused serious economic injury to specialty and row crops in the mid-Atlantic region. Growers have targeted H. halys with broad-spectrum materials by increasing the number of and decreasing the interval between insecticide applications. While it is known that adults reliably respond to semiochemical cues, much less is known about the response of H. halys to visual stimuli. Field observations suggest that H. halys adults respond to light-based stimuli, with large aggregations of adults documented at outdoor light sources and captured in commercial blacklight traps. Therefore, we conducted a series of studies aimed at identifying optimal wavelengths and intensities of light attractive to H. halys adults. We found that intensity and wavelength of light affected H. halys response in the laboratory and field. In the laboratory, H. halys demonstrated positive phototactic responses to full-spectrum and wavelength-restricted stimuli at a range of intensities, though the levels of stimulus acceptance and attraction, respectively, changed according to intensity. The species is most attracted to white, blue and black (ultraviolet) wavelength-restricted stimuli in the laboratory and field. In the field, traps baited with blue light sources were less attractive to non-target insect species, but white light sources were more attractive to H. halys indicating that these two light sources may be good candidates for inclusion in light-based monitoring traps.

Title (up) Beyond All-Sky: Assessing Ecological Light Pollution Using Multi-Spectral Full-Sphere Fisheye Lens Imaging Type Journal Article
Year 2019 Publication Journal of Imaging Abbreviated Journal J. Imaging
Volume 5 Issue 4 Pages 46
Keywords Instrumentation; Skyglow
Abstract Artificial light at night is a novel anthropogenic stressor. The resulting ecological light pollution affects a wide breadth of biological systems on many spatio-temporal scales, from individual organisms to communities and ecosystems. However, a widely-applicable measurement method for nocturnal light providing spatially resolved full-spectrum radiance over the full solid angle is still missing. Here, we explain the first step to fill this gap, by using a commercial digital camera with a fisheye lens to acquire vertical plane multi-spectral (RGB) images covering the full solid angle. We explain the technical and practical procedure and software to process luminance and correlated color temperature maps and derive illuminance. We discuss advantages and limitations and present data from different night-time lighting situations. The method provides a comprehensive way to characterize nocturnal light in the context of ecological light pollution. It is affordable, fast, mobile, robust, and widely-applicable by non-experts for field work.
