I confess to finding this article somewhat disturbing: http://www.pressherald.com/news/College-students-turtle-project-takes-dark-twist.html.
The student in question put a realistic rubber turtle on the road to see what would happen. Over the next hour seven drivers swerved in order to deliberately hit it, while several more tried to hit it but missed. As Hal Herzog, a Western Carolina University psychology professor said, “Sometimes humans feel a need to prove they are the dominant species on this planet by taking a two-ton metal vehicle and squishing a defenseless creature under the tires.” This activity has been credited with being at least partially responsible for the slow decline in box turtles, who can take 10 minutes to get across a road.
According to the article these turtles take “seven or eight years to become mature enough to reproduce, and in that time, they might make several trips across the road to get from one pond to another, looking for food or a place to lay eggs. A female turtle that lives 50 years might lay over 100 eggs, but just two or three are likely to survive to reproduce.”
