Methods for Assessment and Monitoring of Light Pollution around Ecologically Sensitive Sites

Journal of Imaging, 2019
Since the introduction of electric lighting over a century ago, and particularly in the decades following the Second World War, indications of artificial light on the nighttime Earth as seen from Earth orbit have increased at a rate exceeding that of ...

Salivary melatonin onset in youth at familial risk for bipolar disorder [PDF]

, 2019
Melatonin secretion and polysomnography (PSG) were compared among a group of healthy adolescents who were at high familial risk for bipolar disorder (HR) and a second group at low familial risk (LR).

Personal light-at-night exposures and components of variability in two common shift work industries: uses and implications for future research

Scandinavian Journal of Work, Environment & Health, 2018
OBJECTIVES: Shift workers’ increased risk of various adverse health outcomes has been linked to light-at-night (LAN) exposure, but few studies have measured LAN exposure in workplaces.

Night-time neuronal activation of Cluster N in a day- and night-migrating songbird. [PDF]

, 2010
Magnetic compass orientation in a night-migratory songbird requires that Cluster N, a cluster of forebrain regions, is functional. Cluster N, which receives input from the eyes via the thalamofugal pathway, shows high neuronal activity in night-migrants ...

Coronatine Facilitates Pseudomonas syringae Infection of Arabidopsis Leaves at Night. [PDF]

, 2016
In many land plants, the stomatal pore opens during the day and closes during the night. Thus, periods of darkness could be effective in decreasing pathogen penetration into leaves through stomata, the primary sites for infection by many pathogens ...

A single night light exposure acutely alters hormonal and metabolic responses in healthy participants

Endocrine Connections, 2017
Many animal studies have reported an association between melatonin suppression and the disturbance of metabolic responses; yet, few human studies have investigated bright light effects on metabolic and hormonal responses at night. This study investigated

Clouds, shadows, or twilight? Mayfly nymphs recognise the difference [PDF]

, 2006
1. We examined the relative changes in light intensity that initiate night-time locomotor activity changes in nymphs of the mayfly, Stenonema modestum (Heptageniidae).

Using all-sky differential photometry to investigate how nocturnal clouds darken the night sky in rural areas

, 2019
Artificial light at night has affected most of the natural nocturnal landscapes worldwide and the subsequent light pollution has diverse effects on flora, fauna and human well-being. To evaluate the environmental impacts of light pollution, it is crucial
