Researchers Explore the Effects of Artificial Light on Turtle Populations

A new study led by the Australian Institute of Marine Science (AIMS) aims to investigate the impact of artificial light at night (ALAN) on the behavior of turtle hatchlings, particularly green turtles, a threatened species. Researchers found that hatchlings typically rely on natural cues like darkness and starlight to navigate towards the ocean. However, coastal development and its artificial lights can disrupt this instinct, increasing their vulnerability to predation, exhaustion, and dehydration. The collaboration with Pendoley Environmental and the WA Department of Biodiversity, Conservation and Attractions will explore how different light types and intensities affect hatchlings’ navigation. Early experiments using a Y maze indicate that light intensity influences attraction levels, with higher intensities drawing more interest from the hatchlings. This research aims to provide guidelines for coastal development, ensuring the protection and sustainability of turtle populations in light of existing environmental threats.
