Title Twice daily melatonin peaks in Siberian but not Syrian hamsters under 24 h light:dark:light:dark cycles Type Journal Article

Abstract The daily pattern of blood-borne melatonin varies seasonally under the control of a multi-oscillator circadian pacemaker. Here we examine patterns of melatonin secretion and locomotor activity in Siberian and Syrian hamsters entrained to bimodal LDLD8:4:8:4 and LD20:4 lighting schedules that facilitate novel temporal arrangements of component circadian oscillators. Under LDLD, both species robustly bifurcated wheel-running activity in distinct day scotophase (DS) and night scotophase (NS) bouts. Siberian hamsters displayed significant melatonin increases during each scotophase in LDLD, and in the single daily scotophase of LD20:4. The bimodal melatonin secretion pattern persisted in acutely extended 16 h scotophases. Syrian hamsters, in contrast, showed no significant increases in plasma melatonin during either scotophase of LDLD8:4:8:4 or in LD20:4. In this species, detectable levels were observed only when the DS of LDLD was acutely extended to yield 16 h of darkness. Established species differences in the phase lag of nocturnal melatonin secretion relative to activity onset may underlie the above contrast: In non-bifurcated entrainment to 24 h LD cycles, Siberian hamsters show increased melatonin secretion within approximately 2 h after activity onset, whereas in Syrian hamsters, detectable melatonin secretion phase lags activity onset and the L/D transition by at least 4 h. The present results provide new evidence indicating multi-oscillator regulation of the waveform of melatonin secretion, specifically, the circadian control of the onset, offset and duration of nocturnal secretion.

Title Behavioral Responses of the Invasive Halyomorpha halys (Stål) (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 (down) 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 Public Space Humanization in a Night City Type Journal Article
Year 2019 Publication Light & Engineering Abbreviated Journal L&E
Volume (down) 27 Issue 5 Pages 28-36
Keywords Society; Planning
Abstract Humanisation of public spaces is an important part of development strategies for a modern city. Design of a luminous environment plays a significant part in this process. We can see a correlation between the existing examples of humanoriented lighting of spaces and the scientific understanding of humanism. This helps us set a goal of space humanisation, select specific tasks that are solved by humanised public spaces, and define factors influencing humanistic quality of the environment at the phase of lighting design.
