Role of delinquent young “orphan” male elephants in high mortality of white rhinoceros in Pilenesberg National Park, South Africa

We describe white rhinoceros (Ceratotherium simum) mortality at Pilanesberg National Park, South Africa, focussing on mortality caused by African elephant (Loxodonta africana). We reconstructed records from a range of historical sources, and estimated that up to 49 rhino were killed by elephant. There was confirmed mortality in 1994 and 1996, and based on patterns, we […]

Mineral concentrations in serum/plasma and liver tissue of captive and free-ranging Rhinoceros species

Abstract 10.1002/zoo.20043.abs Mineral implications in health issues of captive rhinos have received much attention lately. This study was undertaken to establish reference values for the mineral status of rhinos. Serum/plasma samples of free-ranging black (Diceros bicornis) and white (Ceratotherium simum) rhinos and of captive black, white, Indian (Rhinoceros unicornis), and Sumatran (Dicerorhinus sumatrensis) rhinos, as […]

Comparative analysis of gonadal and adrenal activity in the black and white rhinoceros in North America by noninvasive endocrine monitoring

Abstract 10.1002/zoo.10028.abs Patterns of fecal reproductive steroid metabolites and adrenal corticoids were characterized for 12- to 24-month periods in black (n = 10 male, 16 female) and white (n = 6 male, 13 female) rhinoceroses at 14 institutions. All black rhinoceros females exhibited at least some ovarian cyclicity on the basis of fecal progestogen analysis […]
