Cool Dudes and Hot Mammas: How Temperature Determines Sex in Turtles

Cheryl S. Rosenfeld

Associate Professor, Biomedical Sciences, and Research Faculty, Thompson Center for Autism and Neurobehavioral Disorders

Many turtles lack sex chromosomes. Instead, sex determination is due to temperature. Rising egg incubation temperature increases the hormone estrogen, which programs the gonad and brain to be female. However, this pathway also renders turtles to be susceptible to environmental estrogens and climate change. This presentation will examine how these factors might be affecting several turtle species.
