Genetic admixture of Kruger National Park black rhino (Diceros bicornis minor): conservation implications
Black rhinoceroses (Diceros bicornis) have been extirpated from most of their historic range with the remaining individuals (ca. 5200) living in geographically isolated populations. Management priorities include creating new populations whilst maintaining genetic diversity and promoting gene flow …

The biochemical analysis of southern African rhinoceros populations
… in the numbers of the five extant species of rhinoceroses world-wide, mainly as a result of poaching, have placed these species in imminent danger of extinction. This emphasizes the need to understand the relationships among the different species of rhinoceros. The advances in molecular …

Conservation and population genetics of African and Asian rhinoceros
There are five living species of rhinoceros inhabiting Africa and Asia: black rhinoceros (Diceros bicornis), white rhinoceros (Ceratotherium simum), Indian rhinoceros (Rhinoceros unicornis), Javan rhinoceros (Rhinoceros sondaicus) and Sumatran rhinoceros (Dicerorhinus sumatrensis). Anthropogenic …

Red blood cell pathophysiology : comparative and diagnostic aspects
Captive black rhinoceroses in the United States are threatened by three major clinical disorders. Among these, haemolytic anaemia ranks as the number one cause of death. The object of this study therefore was to determine the metabolic lesion responsible for the haemolytic anaemia. Since black …

Elevated levels of low molecular weight substances in the red cells of some mammalian species imply unsuspected antioxidant strategies
… curious metabolic anomalies in the red cells of black rhinoceros, and in particular a high free tyrosine level, suggested that a range of unusual, but presumeably physiological, processes might be found in mammalian red blood cells. As a follow-up to this, low molecular weight metabolites were …
