While aromatase activity remains low for much of development in individuals that exhibit TSD, during the thermosensitive period, variations in temperature increase the activity of aromatase. The developmental period during which sex determination occurs can be discovered by incubating eggs at the male-producing temperature for a certain amount of time and then shifting the eggs to an incubator at the female-producing temperature and vice versa.
The best-known sequential hermaphrodite in our local waters is the common snook. These efforts and continued population monitoring will allow us to assess the impacts of changing temperatures on sex ratios of new Spotted Turtle generations.
