The taxonomic relationships within the dwarf chameleons (Bradypodion) of southern Africa have long been controversial. Although informal phenotypic groups have been suggested, the evolutionary relationships among the 15 recognised species in southern Africa have not been previously investigated. To investigate the relationships among species within this genus, fragments of two mitochondrial gen...

Infection of wild animals by bovine tuberculosis (bTB) is raising concern worldwide. This article reviews the current epidemiological situation, risk of emergence and control options at the wildlife–livestock–human interface in sub-Saharan Africa. In livestock, bTB has been confirmed in the majority of countries from all parts of the continent. Wildlife infection is confirmed in seven countries...

Mining, as defined by Stocks and Down is the ‘removal of minerals from their natural geological environment and their transport to the point of processing or use1’. As so defined mining has, in one form or another, been providing essential raw materials for tens of thousands of years. Although metal ores were first mined in southern Africa (south of 15°S) approximately 2 000 years ago, minerals...

The objective of this study is to quantify the nature of the mechanisms of southern Africa rainfall variability, unrelated to the El Nino Southern Oscillation, by means of a simple empirical composite analysis, as a baseline for a more detailed study.

Recent estimates suggest that more than 10% of Southern Africa is HIV+. This article is based on a research study of sixty four pastoral care projects focussing on the HIV/AIDS pandemic in Southern Africa. The projects, which fall under the auspices of the Southern African Catholic Bishops' Conference AIDS office, focus on both education for HIV prevention and the pastoral care of people living...

The origins of herding practices in southern Africa remain controversial. The first appearance of domesticated caprines in the subcontinent is thought to be c. 2000 years BP; however, the origin of this cultural development is still widely debated. Recent genetic analyses support the long-standing hypothesis of herder migration from the north, while other researchers have argued for a cultural ...

Phylogenetic relationships were examined for 29 southern African West Nile virus (formal name West Nile virus [WNV]) isolates from various sources in four countries from 1958 to 2001. In addition, sequence data were retrieved from GenBank for another 23 WNV isolates and Kunjin and Japanese encephalitis viruses. All isolates belonged to two lineages. Lineage 1 isolates were from central and Nort...

As a result, 14 countries in East and Southern Africa were identified as priority countries and initiated programmes to expand the provision of male circumcision (Botswana, Ethiopia, Kenya, Lesotho, Malawi, Mozambique, Namibia, Rwanda, South Africa, Swaziland, Tanzania, Uganda, Zambia and Zimbabwe).2 The Central African Republic was subsequently identified as a high priority country for VMMC pr...

The goal of this paper is to review the status of Human-Computer Interaction (HCI) in South Africa today. The formation and development of CHI-SA, the South African chapter of ACM SIGCHI, is discussed together with the role this organization is playing in encouraging and fostering HCI in Southern Africa.
