A study of the diet and food preferences of the rock hyrax was conducted on rangeland in southern South West Africa in response to complaints by Karakul sheep farmers that the species was competing wilh livestock for grazing. The botanical composition of the dit was quantitatively determined by analysing stomach contents using leaf epidermis anatomy to identify Monocotyledons and gross morphology to identify Dicotyledons.
South West Africa is a country traditionally rich in game. The numbers and distribution of the various game species. the influence of man and the development of legislation around the protection and utilisation of game is discussed.

Resource partitioning in two coexisting owls. spotted eagle (Bubo africanus) and barn (Tyto alba) was studied in the Kuiseb. Significant diffirences in the proportions of different captured prey were found to exist between owls, habitats, seasons, and prey size classes.
A chromosome preparation technique has been developed over several years for use primarily with birds. The technique is similar to others in general use being based essentially on the methods of Ohno and Shoffner. Modifications were developed specilically for use under ""field laboratory"" conditions, with a minimum or steps and apparatus, including tile option of using biopsy material without cell culture.
Aspects of habitat, population, and water balance in a harpagophorid millipede (probably Harpagophora nigra Attems) were studied from winter-collected specimens in the Namib Desert. Most individuals were relatively small occupying soil adjacent to granite boulders of an inselberg at Mirabib Hills.
