Urinary corticosteroid excretion patterns in the okapi (Okapia johnstoni).
Stress is known to alter a variety of biological processes, including behavior and reproduction. It is therefore important to understand the stress levels of animals in captivity, especially those for whom captive breeding is a priority, such as the okapi. Levels of stress hormones can be measured from samples collected noninvasively, such as urine or feces, which are preferable with nondomesti...

15 صفحه اولThe Cervical Osteology of Okapia johnstoni and Giraffa camelopardalis
Giraffidae is the only family of ruminants that is represented by two extant species; Okapia johnstoni and Giraffa camelopardalis. Of these taxa, O. johnstoni represents a typical short-necked ungulate, and G. camelopardalis exemplifies the most extreme cervical elongation seen in any ruminant. We utilize these two species to provide a comprehensive anatomic description of the cervical vertebra...
متن کاملEnhancing knowledge of the ecology of a highly elusive species, the okapi (Okapia johnstoni), using non-invasive genetic techniques
Okapi (Okapia johnstoni) are an even-toed ungulate in the family Giraffidae, and are endemic to the Democratic Republic of Congo (DRC). Very little is known about okapi ecology in the wild. We used non-invasive genetic methods to examine the social structure, mating system and dispersal for a population of okapi in the Réserve de Faune à Okapis, DRC. Okapi individuals appear to be solitary, alt...
