Artificial night sky poses serious threat to coastal species

The artificial lighting which lines the world’s coastlines could be having a significant impact on species that rely on the moon and stars to find food, new research suggests.

Creatures such as the sand hopper (Talitrus saltator) orientate their nightly migrations based on the moon’s position and brightness of the natural night sky.

However, a study by the University of Plymouth and Bangor University shows the presence of artificial light originating from cities several kilometres away (also known as artificial skyglow) disrupts the lunar compass they use when covering long distances. MORE
