Reproduction in the giraffe in relation to some environmental factors

Environmental influences on reproduction in female giraffe were investigated by calculating conception dates for 123 calves and twenty foetal giraffe from the eastern Transvaal, South Africa. Of these, 60% occurred during the 4 months December to March. This period is the peak of the austral summer when plant leaf production is at a maximum, the preferred food species of the giraffe are abundant and the protein and energy content of these are high. Rainfall is also highest at this time.

Food Selection by Transvaal lowveld giraffe as determined by analysis of stomach contents

Food selection by giraffe in the Transvaal lowveld was studied by identifying plant fragments from stomach contents over a 1 year period. Large fragments were randomly taken from the material while small fragments were taken from a 50 ml sample. Identifications were based on diagnostic keys and over 8000 fragments were classified. The validity of the samples was tested and found to be satisfactory. Giraffe were found to subsist mainly on leaves of trees and shrubs. Fruit, flowers and twigs

The behaviour of giraffe giraffa camelopardalis in the eastern transvaal

The giraffe in South Africa live entirely in the Eastern Transvaal, a lowveld region primarily of grass or veld with scattered bushes and low trees. The giraffe browse on a wide variety of trees in the spring and fall when few leaves are available, but in summer when all the trees are in foliage they are much more selective. The giraffe spend most of the day and part of the night feeding, especially the early morning and late afternoon. In

Feeding habits of spotted hyaenas in a woodland habitat

The feeding habits of spotted hyaenas were recorded during a 2-year full-time study in the Lowveld of South Africa. The animals were observed for 335 h at night using artificial light. These results were supplemented by the analysis of 200 regurgitations and 527 scats collected on a monthly basis over 12 months, with a consideration of the availability of different prey species. It is argued that regurgitation gets rid of any excess of hair, the remainder in the scats giving
