The Namib Desert of SWA/Namibia supports a rich tenebrionid fauna. Endrdy-Younga (1978) discusses the distribution patterns of southern African groups, including those of the Namib Desert. Penrith tabulates habitat preferences for Zophosini and Adesmiini. The central portion of this coastal desert is sharply divided into three major habitat types: dune field, riverbed, and gravel plain. Much emphasis has been placed on the biology of dune tenebrionids, with special regard to their adaptations. However, comparatively little has been published on the tenebrionids of the river-bed habitat and almost nothing on those of the gravel plain.
Several surveys of coastal birds have recently been conducted in southern Africa but little is known of the birds of the Diamond Coast of South West Africa since access is restricted. The only section of mainland readily accessible between Sandvis and the Orange River is at Lderitz. Data are presented for bird densities along 46 km of coast and at five islands in the Lüderitz area. Resident waders accounted for 57.9% of all waders on the mainland. The Lüderitz Sewage Works are identified as an important habitat for birds.
An analysis of the catches of teleost fish by visitors to Terrace Bay is presented. The analysis is based on both a card census and a check of the total number of fish caught at Terrace Bay. Both daily catch rates (8,7 fish/day) and total catches (48 308) were high. Significant differences were apparent in the species of fish sought by local and visiting anglers, which in turn resulted in differential catch rates for the two categories of anglers.
Surveys of the vegetation in rock hyrax habitat in the Karas Mountains, southern South West Africa, were conducted to approximate the relative availability of herbage for use in a food habits study. The survey technique ( bad on plant dimensions) and its shortcomings are descriptionbed. It was found that sampling was inadequate for infrequently encountered species but consistently reflected the relative proportions of the common trees, shrubs and grasses. Rock hyrax habitat is suitable for browsers.
Ten tame eland (Taurorragus oryx), four kudu (Tragelaphus strepsiceros), two gemsbok (Oryx gazella), six springbok (Antidorcas marsupialis) and 33 domestic goats were drenched by stomach tube with extracts of the poisonous plant gifblaar (Dichapetalum cymosum) (Hooker) Engler and PrantI. The lesions caused by gifblaar are descriptionbed.
Measured activity of wildebeest was translated into an energy demand by allocating theoretical energetic values to each of the various activities, using data from domestic ruminants. Thereby an estimate of the cost of maintenance and activity was obtained. The phenomena of growth, gestation, lactation and homeothermy were similarly estimated.
