Population statistics and carrying capacity of large ungulates in Whovi Wild Area, Rhodes Matopos National Park, Zimbabwe Rhodesia

Population data for introduced large ungulates, are presented to demonstrate population growth in terms of numbers and biomass in the Whovi Wild Area of the Rhodes Matopos National Park, Zimbabwe Rhodesia. Peak calving in relation to food requirements of different species is discussed. Standing crop of large ungulates was calculated and compared with carrying capacity as predicted by Coe et al. (1976)

Perinatal maternal and neonatal behaviour in the captive reticulated giraffe

A captive reticulated giraffe was observed constantly for three weeks prior to, and periodically for 90 days subsequent to, the birth of her calf. Extensive observations were made of the birth sequence, feeding, drinking, sleeping and one instance of an infant distress call, as well as observations of the initiation of maternal behaviour (including licking, nursing, placentophagia, and what appeared to be helping the calf to stand, guiding the calf’s movements, and attempts to respond to the calf’s distress call).

Food habits of giraffe in Tsavo National Park, Kenya

In the context of a broader ecological investigation, food habits of giraffe were studied in Tsavo National Park (East). The only method employed was direct observation of feeding animals in the field. Each instance in which one animal fed on one individual plant was counted as one food record for this plant species; 4025 records are analysed. A total of sixty-six plant species was found to be eaten, the great majority being trees and shrubs, with a few creepers and

Notes on the biology of the giraffe

During a 3-year study in Nairobi National Park, 1965–1968, 250 giraffe were identified by their neck markings. The herd structure of these animals was studied, including the relationships between particular individuals. Population information collected included the times of calving, the growth and longevity of giraffe, their reproductive potential, the age structure of the population and its density. Immigration, emigration and home range studies were completed with the help of radio telemetry equipment. The effect of giraffe on the vegetation and

Horns and other bony structures of the skull of the giraffe, and their functional significance

The gross morphology of the giraffe skull and its superficial anatomy is described. The parietal, median, occipital, orbital, azygous horns and other exostoses are described. The giraffe’s peculiar mode of intra-specific fighting is explained and the features of the giraffe’s skull are related to this. It is concluded that the skull of the male giraffe is highly specialised for its particular mode of fighting. The male differs in this respect from the female whose skull is not so developed and

Circulation of the Giraffe

The long neck of the giraffe presents a unique problem in the regulation of the systemic arterial blood pressure and in the maintenance of the cerebral circulation. In 1954, Goetz and Budtz-Olsen succeeded in measuring the arterial blood pressure in a standing, unanesthetized giraffe. In this animal, approximately 13 feet tall, the carotid artery mean pressure was found to be 200 mm. Hg at the base of the brain. The present study was undertaken 2 years later as a sequel

Giraffe Intergradation in Kenya

Since data concerning the distribution of the species and races of giraffe are scarce, the following observation, which concerns apparent hybrids between the reticulated giraffe (Giraffa camelopardalis reticulata) and the Masai giraffe (G. capensis tippelskirchi), a race of the southern species, seems noteworthy. The reticulated giraffe inhibits such low-level deserts in Kenya as lie north of the Tana River and east of Lake Rudolph, and also adjacent parts of southern Abyssinia; while the Masai giraffe occurs in deserts, bush country
