BPA overrides temperature to decide turtle sex
The environmental build-up of bisphenol A (BPA) can result in a life-changing shift for aquatic animals. For painted turtles, exposure to this chemical can disrupt sexual differentiation,, according to new research in the General and Comparative Endocrinology. Scientists at the University of Missouri have teamed up to show how low levels of certain endocrine disruptors like BPA can cause males to possess female gonadal structures in newly-hatched turtles. This collaboration between MU, Westminster College, the U.S. Geological Survey (USGS) and the Saint Louis Zoo exposed turtle eggs to levels of BPA similar to those currently found in the environment.
