Enamel hypoplasia provides insights into early systemic stress in wild and captive giraffes (Giraffa camelopardalis)

Enamel hypoplasia, a developmental tooth defect, provides a permanent record of systemic stress during early life. The incidence and distribution of linear enamel hypoplasia has been used by anthropologists and palaeontologists to assess the health status of past populations but has not been applied by wildlife biologists studying extant animals. This study investigates enamel hypoplasia in 23 Giraffa camelopardalis skulls from wild and captive animals of various ages and sex to determine whether any systemic stress events are unique to

On reconstructing Giraffa sivalensis, and extinct giraffid from the Siwalik Hills, India

Giraffa sivalensis occurred during the Plio-Pleistocene period and probably represents the terminal species of the genus in Southern Asia. The holotype is an almost perfectly preserved cervical vertebra of disputed anatomical location. Although there is also uncertainty regarding this animal’s size, other specimens that have been assigned to this species include fragments of two humeri, a radius, metacarpi and teeth. Here we estimate neck length, leg length and body mass using interspecific and, unusually, ontogenetic allometry of extant giraffe skeletal

The past and present distribution of some African ungulates

Synopsis: A comparison has been made between the recent densities and distributions of African mammals of the genera: Equus, Ceratotherium, Diceros, Hippopotamus, Choeropsis, Hyemoschus, Giraffa, Okapia, Damaliscus, Alcelaphus, Connochaetes, Taurotragus, Tragelaphus, Boocercus, Strepsiceros, Limnotragus, Syncerus, with those at the turn of the present century. Information has been obtained from literature, by personal contact, and in a tour of East Central and South Africa. This monograph is divided into fifteen parts, each containing the known distribution and density of a family

Giraffe and Okapi: Africa’s forgotten megafauna

The Giraffidae family includes only two living species of ungulates: the giraffe (Giraffa camelopardalis) and the okapi (Okapia johnstoni), both restricted to the African continent. Taxonomically, the Giraffa and Okapia genera separated from each other approximately 16 million years ago (Hassanin et al., 2012), and they now exhibit as many differences as similarities. Today Okapia is represented by one species (Okapia johnstoni; Hart, 2013), though with surprisingly high genetic variation (Stanton et al., 2014), whereas nine subspecies of giraffe are

Frothy bloat and serous fat atrophy associated with insufficient fibre intake in a giraffe (Giraffa camelopardalis)

Malnutrition is a common cause of morbidity and mortality in captive giraffe (Giraffa camelopardalis). Frothy bloat, a nutrition-related disease of domestic ruminants, has not previously been reported in Giraffidae. A 10-year-old female reticulated giraffe (G. c. reticulata) had a chronic cough and died in February 2007 following a two-month period of weight loss. Multiple nutrition-related abnormalities were identified post mortem: frothy bloat appeared to have been the immediate cause of death; there was no fibrous material in the forestomachs; and
