Do sea turtles orient toward green Snaplight light sticks under night sky light conditions?
This experiment was identical to Experiment 1 except that it was performed outdoors under a night sky to more closely simulate lighting conditions that turtles encounter in the open ocean. Results are shown in Figures 6 and 7. Results from the Hotelling test indicate that the turtles in the control treatment were not significantly oriented as a group. In the experimental treatment, the turtles were significantly (p<0.001) oriented with a mean angle of 343.8°. The control and experimental treatments were significantly different (F-test, p<0.001). These results indicate that turtles oriented toward green Snaplight light sticks despite the presence of ambient light in the night sky.
