Abstract
A captive-born female sub-adult Eastern black rhinoceros (Diceros bicornis michaeli) developed areas of non-ulcerated, non-pruritic depigmentation around the nares at 2 yr of age. Over the subsequent 18 mo, the symmetrical multifocal depigmented macules increased in size and distribution to include...

Theriogenology (73)8 2010
Abstract
The objective was to identify an extender and cryoprotectant combination for Indian rhinoceros (Rhinoceros unicornis) sperm that yielded high post-thaw sperm quality. Male Indian rhinoceroses (n=6; 7.5-34 yr old) were anesthetized and subjected to a regimented electroejaculation procedure (75-100 mA...

Ecological Applications (19)7 2009
Abstract
We model the poaching and population dynamics of the one-horned rhinoceros within an integrated framework of ecological, socioeconomic, political, and legal dimensions. The poaching model for rhinos in Royal Chitwan National Park (RCNP) in Nepal is combined with the population model for the species...

Ecological Applications (19)7 2009
Abstract
We ask how interactions between herbivory and fire act to shape savanna vegetation dynamics via their effects on tree populations in Hluhluwe iMfolozi Park in KwaZulu Natal, South Africa, a savanna with a full complement of native large mammals. We examined the effects of herbivore exclusion on tree...

Abstract
Babesiosis is a potentially fatal disease in black rhinoceroses. Blood specimens collected from black rhinoceroses from Etosha National Park (n = 29) and Damaraland (n = 22), Namibia, were subjected to polymerase chain reaction using Theileria and Babesia genus-specific primers and reverse line blot...

Biology Letters (4)4 2008
Abstract
We suggest that evolution of a carotid rete, a structure highly developed in artiodactyls but absent in perissodactyls, was at least as important. The rete confers an ability to regulate brain temperature independently of body temperature. The net effect is that in hot ambient conditions artiodactyl...

In North America broad-based research networks explore the interaction of vertebrates, their characteristic arrays of pathogens and emergent disease. A diversity of programmes address the impact of environmental change on animal health, zoonoses, and human health, but as yet no comprehensive framewo...

Abstract
These results allow conclusions on the suitability of diets fed in captivity: the black rhinoceros is prone to several uncommon diseases that have been suspected to be linked to oxidative damage, possibly due to the disposition of this species to excessive iron storage. An unnatural dietary loading...

Abstract
Tuberculosis infections caused by Mycobacterium (M.) pinnipedii in a South American sea lion, Bactrian camel, and Malayan tapirs kept in two zoological gardens spanning a time period of 5 years are reported. The zoos were linked by the transfer of one tapir. Conventional bacteriological and molecula...

Sexual segregation in ungulates has important conservation and theoretical implications, but despite numerous studies, the impetus for this behavioral pattern remains a topic of debate. Sexual segregation hypotheses can be broadly grouped into social and ecological explanations, but only ecological...

Abstract
Free-ranging browsing herbivores ingest a range of secondary plant compounds, such as tannins, with their natural diet. As many of these substances have been shown to have antibacterial properties, it could be speculated that a lack of such compounds in captive zoo diets could favour the growth of p...

Current Biology (17)20 2007
Abstract
In testing the 'social brain hypothesis' with comparative data, most research has used group size as an index of cognitive challenge. Recent work suggests that this measure is too crude to apply to a wide range of species, and biologists may need to develop other ways of extending these analyses.

Reproduction in Domestic Animals (42 Suppl 2)s2 2007
Abstract
Over the last few decades, rhinoceroses and elephants became important icons in the saga of wildlife conservation. Recent surveys estimate the wild Asian (Elephas maximus) and African (Loxodonta africana) elephant populations to be, at most, 50 250 and 637 600 respectively. For the five rhinoceros s...
