Convergence and divergence in prey of sympatric canids and felids: Opportunism or phylogenetic constraint?
Since the canids and felids diverged in the mid-Eocene or earlier, each family has developed a suite of morphological and behavioural adaptations for obtaining and consuming prey. We here distinguish between prey taxa ...
Affinities of some common estuarine macroinvertebrates to salinity and sediment type: Empirical data from Eastern Cape estuaries, South Africa
Fourteen species of subtidal macrobenthos present in thirteen Eastern Cape estuaries, South Africa, were compared with regard to correlations with two important environmental variables (salinity and sediment mud content). ...
Characterization of Colletotrichum species associated with diseases of Proteaceae
Colletotrichum spp. are known to occur on and cause diseases of Proteaceae, but their identities are confused and poorly understood. The aim of the present study thus was to identify accurately the Colletotrichum spp. ...
Poverty at the household level: A review of theory and South African evidence
This paper focuses on the allocation of household resources among the poor in South Africa, looking at both the theoretical issues and the empirical findings of recent research work. Distinguishing between Becker's unitary ...
South African banks and the unbanked: Progress and prospects
Commercial Banks Traditionally do not serve low-income earners, micro-entrepreneurs and the poor (collectively referred to as the unbanked), chiefly because the high costs involved make it unattractive. The big four of ...
The retail of South African game meat: Current trade and marketing trends
The purchasing and marketing of game meat by supermarkets and butcheries in the Western Cape Province of South Africa was researched by the survey method. Two supermarket groups in South Africa indicated that they do market ...
Population estimation and harvesting potential for game in arid Namibia
We determined the densities of game on mixed game and livestock ranches in arid Namibia over three years using ground survey techniques and distance and point sampling. Annual game yield estimates varied considerably, ...
Effect of soil tillage, crop rotation and nitrogen application rates on plant-N content of spring wheat (Triticum aestivum L.) in the Swartland wheat-producing area of the Republic of South Africa
Studies on nitrogen content in spring wheat were conducted during the 2000 and 2001 growing seasons as part of a long-term tillage and crop rotation trial. Four tillage methods were used, namely conventional tillage (CT), ...
The effect of temperature on the germination of six selected weed species
Field-collected seeds were incubated in a germination cabinet at three temperature regimes and germination percentage was determined after incubation. Species such as Arctotheca calendula, Avena fatua, Bromus diandrus and ...
