Composition and patterns of the main biotic and abiotic components or the system are outlined. Notes on biology and ecology of 127 recorded animal species are given, with special attention to the apterous arthropods which dominate the system. The results of a one-year trapping survey are used to illustrate habitat preferences, diet activity cycles and seasonal occurrences of the majority of the species. Endemism and geographical distribution of the beetle fauna are discussed.
Species composition of prey eaten by three groups of spotted hyaena (Crocuta crocuta) in the central Namib Desert was evaluated. Age and sex categories of major prey are based on 55 carcasses and diets on 595 scats collected over 12 months. Gemsbok was the most important food item in the overall diet of two groups, but in a third group gemsbok and mountain zebra are almost equally represented.
Counts of waders (Charadrii) and other coastal birds (excluding gulls Larus spp.) are given for the islands off South West Africa, and bays in the adjacent mainland coastline, A total of 3 460 birds was counted during November - December 1978 of which 2 467 were waders. Palaearctic migrants formed 76.3 % of the waders.
