摘要:

An account is given of the stream fauna of Table Mountain. The analysis is based on intensive sampling, during all months of the year, in a selected stream, supplemented by collections from all the main streams on the mountain. An annotated faunal list includes records from published literature. It is pointed out that Table Mountain, with the rest of the Cape Peninsula Range, is virtually an island as far as the mountain stream fauna is concerned. This fauna is compared with that of the mainland mountains and reasons advanced for its paucity and lack of endemicity.

摘要:

Palaeogeographies of the Agulhas Bank for three low sea-level stages during the Pleistocene are presented (−140 m, −100 m and −50 m). Although they are specifically considered in relation to the last transgression (Flandrian, post-Weichsel/Würm), they are applicable to any of the previous glacial periods. In each case, the bedrock geology and expected superficial sediment cover are outlined, and general conclusions as to soil types, terrain, drainage, etc., are presented. The extended courses of local rivers in the Pleistocene are postulated from bathymetric and sedimentological data.

摘要:

Quantitative microscopic analysis of impala (Aepyceros m. melampus) faeces showed that epidermi of grass leaves persist undigested in fairly large fragments, and that interspecific anatomical variation provides diagnostic criteria for identification of these grasses. Relative abundance of these species growing in the impala habitat was determined and a comparison between relative abundance and relative amount eaten showed significant selection for or against different species. Selection was attributed to palatability. In those species where selection was not significant, it is suggested that the relative amounts eaten were probably determined by their abundance.

摘要:

In 1964 fragments of a fossilized human skeleton were found near Windhoek, South West Africa. The secondary calcium carbonate deposited on the bones indicates that they are older than 3 000 years B.P.

摘要:

A physioecological study of the Umsindusi River at Pietermaritzburg was carried out to estimate the changes in composition taking place during its passage through the city. While little evidence of gross industrial pollution was found, there was a marked enrichment of many constituents, particularly organic substances. A number of sources contribute to the pollution of the Umsindusi, and while this pollution is at present within the self-purification capacity of the river, recovery is slow, and the chemical and bacteriological quality of the water leaving Pietermaritzburg is poor.
