Mother turtle found a perfect spot on the beach to lay her eggs.
Temperature data will be periodically downloaded via Bluetooth from the logger in the nest to an app on volunteer’s phones. The data will help pin point when the hatchlings will emerge from the nest and the ratio of male to female hatchlings. This is called temperature-dependent sex determination (TSD) and is common in reptiles. In our area for loggerhead sea turtles, the temperature where 50% of the embryos will be male and 50% will be female is around 84.6˚F. This is called the pivotal temperature. A mean temperature of 86.9˚F will result in 100% females and a mean temperature of 81.5˚F. will result in 100% males.
