The impacts of artificial light on marine turtles

Salmon M., Wyneken J., Fritz E. & Lucas M. (1992) Seafinding by hatchling sea turtles: role of brightness, silhouette and beach slope as orientation cues. Behaviour 122, 56-77.

Aim: 
To assess the effects of visual and slope stimuli, alone and in combination, on green and loggerhead hatching seafinding.
Type of Study: 
Manipulative experiment
Key Results: 
In an arena set up, both species oriented towards the brightest horizon and oriented away from tall dark silhouettes, at or near eye level. The silhouette cue overrode the light cue when offered competing cues. Slope was a poor cue in orientation.
Response: 
None provided.
