The impacts of artificial light on marine turtles

Price J. T., Drye B., Domangue R. J. & Paladino F. V. (2018) Exploring the role of artificial lighting in loggerhead turtle (caretta caretta) nest-site selection and hatchling disorientation. Herpetological Conservation and Biology 13, 415-422.

Aim: 
To examine the effects of light illuminance levels on nest site-selection and hatchling disorientation of loggerhead turtles
Type of Study: 
Natural experiment
Key Results: 
Higher levels of landward illuminance resulted in lower nesting activity and a lower number of nests laid, particularly when brightness levels exceeded 800 µcd/m². The authors also found a significant relationship between landward illuminance values and hatchling disorientation, but there was no obvious threshold found.
Response: 
No management or policy recommendations provided.
