Ecological Consequences of Artificial Night Lighting

Artificial night lighting inhibits feeding in moths.

One major, yet poorly studied, change in the environment is nocturnal light pollution, which strongly alters habitats of nocturnally active species. Artificial night lighting is often considered as driving force behind rapid moth population declines in severely illuminated countries. To understand these declines, the question remains whether artificial light causes only increased mortality or a...

Effect of the Artificial Night with Facilitated Tucking and Artificial Night Alone on the Physiological Indices of Premature Infants

Background: Preterm birth and admission to neonatal intensive care unit as stressors can cause physiologicalinstability that may lead to prolong hospitalization and mortality. This study aimed to determine the effect of artificialnights and facilitated tucking on the physiological indices of premature infants.Methods: This randomized clinical trial was conducted on 60 preterm ...

Artificial Night Lighting Affects Dawn Song, Extra-Pair Siring Success, and Lay Date in Songbirds

Associated with a continued global increase in urbanization, anthropogenic light pollution is an important problem. However, our understanding of the ecological consequences of light pollution is limited. We investigated effects of artificial night lighting on dawn song in five common forest-breeding songbirds. In four species, males near street lights started singing significantly earlier at d...

Ecological Consequences of Extinction Ecological Consequences of Extinction

The dark side of light at night: physiological, epidemiological, and ecological consequences.

Organisms must adapt to the temporal characteristics of their surroundings to successfully survive and reproduce. Variation in the daily light cycle, for example, acts through endocrine and neurobiological mechanisms to control several downstream physiological and behavioral processes. Interruptions in normal circadian light cycles and the resulting disruption of normal melatonin rhythms cause ...
