Artificial light at night (ALAN) is a pervasive pollutant that alters physiology and behavior. However, the underlying mechanisms triggering these alterations are unknown, as previous work shows dim levels of ALAN may have masking effect, bypassing central clock. Light stimulates neuronal activity in numerous brain regions which could turn activate downstream effectors regulating physiological ...

Human population growth and its associated effects on the environment contribute to rapid decrease of biodiversity worldwide. Artificial light at night (ALAN) is an anthropogenic pollutant that increasing with spread urbanization may declines. ALAN alters migration patterns birds, communication in frogs, impacts reproduction, behavior, physiology multiple other taxa. However, most studies are b...

We report a brief survey on conditions for artificial aurora optical experiments in F region heating with O-mode at the EISCAT Tromsø site using dynasonde data from 2000 to 2017. The results obtained in our survey indicate the following: The possible conditions for conducting artificial aurora experiments are concentrated in twilight hours in both evening and morning, compared with late-night h...

In recent times, there has been an unprecedented increase in usage of electrical lightning. This led to artificial light at night (ALAN), and it suggested as a source environmental pollution. ALAN exposure reported be associated with disruption daily rhythms serious health consequences, such immune, metabolic, cognitive dysfunctions both birds mammals. Given the worldwide pervasiveness ALAN, th...

Flying animals use aerial habitats to forage, communicate and travel. However, human activities that fragment habitat with built structures, noise, chemical or light pollution, may limit the ability of wildlife airspace efficiently. Applying landscape connectivity theory could reveal how long-distance migrants respond sources fragmentation along their migratory routes. Artificial at night is a ...

One contribution of 14 to a theme issue 'The biological impacts of artificial light at night: from molecules to communities'. 1. The challenge Daily, lunar and seasonal cycles of natural light have been key forms of environmental variation across the Earth's surface since the first emergence of life. They have driven the development of biological phenomena from the molecule to the ecosystem, in...

B reast cancer has just been considered as an occupational disease in Denmark. Recent published studies showed that working on rotating night shifts was associated with a higher incidence of subsequent breast cancer among the female nurses and fl ight crews. 5,6 Many factors have association with the development of breast cancer. Some of these risk factors cannot be changed; those included age,...
