Part of the project: The African White Rhinoceros

Conservation update San Diego Zoo – Spring 2012

One step closer to solving a rhino reproductive mystery:

Zoo diets for southern white rhinos may activate their estrogen receptors, so Dr. Christopher Tubbs at the San Diego Zoo Institute for Conservation Research analyzes food extracts to compare them against wild diets.

Researcher Annemieke van der Goot collects samples of spear grass from wild rhinos in a nature reserve in South Africa.These samples will be sent back to the Institute’s Reproductive Physiology lab at San Diego Zoo to be analyzed for phytoestrogen content.
