A recently published study in the journal Pachyderm highlights the ongoing effort of accredited zoos to address challenges and improve the sustainability of endangered species populations in their care. The study, co-authored by scientists from San Diego Zoo Global and Mars Hill University, evaluated fertility issues in captive-born southern white rhinos and determined that diets including soy and alfalfa were likely contributors to breeding challenges.

"The captive southern white rhinoceros (SWR) population is not currently self-sustaining, due to the reproductive failure of captive-born females," said Christopher Tubbs Ph.D, San Diego Zoo Global and lead author of the paper. "Our research into this phenomenon points to chemicals produced by plants present in captive diets, such as soy and alfalfa, as likely causes."
