Reproduction Endocrinology of black, white and Indian Rhinoceroses

Abstract
Reproduction of black (diceros bicornis), white (ceratotherium simum) and greater one-horned (rhinoceros unicornis) rhinoceroses are assessed by faecal steroid analysis. All species of rhinoceroses are endangered due to continued poaching. Understanding of the reproductive biology of the different species is essential to save the remaining populations. Animals monitored in this project are kept in several zoological institutions and on a private game ranch in Namibia.
