Temperature-dependent sex determination is an important biological phenomenon documented in a wide variety of both vertebrates and invertebrates. Among the vertebrates, reptiles are one of the best documented groups that exhibit temperature-dependent sex determination, commonly abbreviated as TSD. This website explores the role that incubation temperature plays in determining the sex ratios of a particular group of reptiles, turtles. The growth, health, evolution, conservation, and indeed very survival of these amazing creatures are affected by TSD.

This website was created as a part of a class project in the Animal Physiology Class at Davidson College.
