Short- and long-wavelength lights disrupt endocrine signalling but not immune function in a nocturnal marsupial.

ABSTRACT: Natural light-dark cycles are responsible for synchronizing an animal's circadian clock with environmental conditions. Consequently, the endocrine system is vulnerable to changes in the external light environment, particularly short-wavelength blue light. Artificial light at night drastically changes the night-time environment by masking natural light cycles and disrupting well-established biological rhythms. The introduction of blue-rich lighting, such as white light-emitting diodes (LEDs), may increase the biological effects of light at night on wildlife. However, flexibility in the spectral composition of LED lighting presents options for wildlife-sensitive lighting, such as long-wavelength amber LEDs. Here we examine the effect of light spectra on circadian physiology in a nocturnal ma
