The social patterns of South West African cheetah are compared to those of the East African cheetah. The data analysed suggest that in the absence of large interspecific competitors grouping of cheetahs occur, prey size expands and litter size increase. No evidence of allo-parenting was found although both females and males exhibited social tendencies.
A survey of the Etosha National Park was carried out to compile a checkIist of its amphibian fauna. Out of the approximately 127 anuran species in southern Africa, only 10 were found within the boundaries of Etosha. One of these, Hildebrandria ornata, is represented by one specimen, which is only the third such frog to be recorded from South West Africa. Rather surprising is the absence of Xenopus. The taxonomy, distribution, habits and breeding behaviour of each species occurring in the area are given.
Five new species namely Sergentomyia cunicula, metzi, vulpes, villosa and welwitschii are descriptionbed. Sergentomyia macintoshi is redescriptionbed, the male for the first time. Their taxonomic position in relation to other Phlebotomine species is discussed.
All but one of the species formerly assigned to the subgenus Sintonius in Southern Africa, are assigned to a new subgenus Capensomyia. Three new species, namely, Sergentomyia drakensbergi, S. kalaharia and S. xera, are descriptionbed. All known southern African species are redescriptionbed. A key to all southern African species is given.
The small mammal community of Tumasberg, an inselburg on the gravel plains of the Namib Desert, was studied by mark-release-recapture methods. The principal small mammals present on a 6 hectare livetrapping grid were: Petromyscus collinus (rock mouse), Aethomys namaquensis (rock rat), Petromus typicus (dassie rat) and Elephantulus rupestris (rock elephant-shrew). This study summarises climatic and microclimatic data for Ganab, 3 km from Tumasberg, and the following ecological and demographic information for the small mammal community; abundance and distribution, home range, activity patterns, recruitment and mortality rates, diet, and reproductive cycles of the small mammals. These data are used to analyse the community structure and ecological interactions of the species.
This paper presents new distributional and some new biological data for the birds of Kaokoland, northern South West Africa. The avifauna of the area was previously reported on by Winterbottom (1966). His expedition visited only one locality of the Skeleton Coast. We have included all coastal records available to us.
