Fluvial deposits, which include calcreted conglomerates, gravels, sands and silts are found up to 50 km west of the present end point or the Tsondab River. They provide evidence for periods of variably increased fluvial activity in the area during the late Cenozoic. Paleoclimatic interpretations of the deposits are difficult, but all were apparently laid down in arid or semi-arid environments. This suggests that although there have been fluctuations in rainfall and run-off in the Tsondab Valley and its headwaters, they have mostly been of limited exlent.
The typological, affinities and inherent interpretative problems of a stoneworking site situated at the edge of the central Namib Desert are discussed. Evidence for manufacturing techniques was obtained although the resultant artefact assemblage was biased because of the removal of finished pieces. It is hoped that this study will provide a contribution towards the establishment of a chronology for the Pleistocene and Early Holocene times of the central Namib.
Sincc the previous century elephant numbers in South West Africa have declined drastically, mainly owing to hunting pressure. While elephants formerly occurred over large parts of the country, they are presently restricted to the northern areas. Based on historical and present distribution patterns three sub-populations can be distinguished in the Etosha National Park.
Response of wildebeest to direct solar radiation and wind was measured at hourly intervals from sunrise to sunset, during cold and hot seasons in the Etosha National Park. The two-dimensional data were statistically analysed by a computer programme package (DIRECT). The findings indicate that wildebeest orientate significantIy in relation to the sun when its attitude is low (< 45) and that during the midday sector wind influences body position.
