The present study analyses the distribution and diversity of sipunculan species inhabiting soft substrata in the Gulf of Valencia and Cape Nao (western Mediterranean) in relation to the characteristics of the sediment. Eighty-seven stations in 14 localities were sampled annually from 2004 to 2008. Nine species were reported, with Aspidosiphon (Aspidosiphon) muelleri being the dominant species i...

In 1954 the Council for Scientific and Industrial Re­ search (CSIR) entered into an agreement with the Uni­ versity of the Witwatersrand. As a result, the Joint CSIR/University Dental Research Unit was formed with Professor James Irving appointed as Director. Professor Irving was a medical graduate of the University of Cape Town with an interest in mineral metabolism and calcifi­ cation. This i...

BACKGROUND The use of biological samples in research raises a number of ethical issues in relation to consent, storage, export, benefit sharing and re-use of samples. Participant perspectives have been explored in North America and Europe, with only a few studies reported in Africa. The amount of research being conducted in Africa is growing exponentially with volumes of biological samples bein...

British imperial control and the civilizing mission of the empire were imposed by a variety of means in the nineteenth century. The role of the missionary in this process has been well studied. By contrast, the contribution of the doctor has been curiously neglected. H. A. C. Cairns, in Prelude to imperialism for instance, has referred extensively to David Livingstone and to Robert Laws, one of...

The build-up of biodiversity is the result of immigration and in situ speciation. We investigate these two processes for four lineages (Disa, Irideae p.p., the Pentaschistis clade and Restionaceae) that are widespread in the Afrotemperate flora. These four lineages may be representative of the numerous clades which are species rich in the Cape and also occur in the highlands of tropical Africa....

In this contribution we present the LptNumerics library for processing of equation systems that are provided via the CAPE-OPEN ESO interfaces. The library provides functionality for the pre-processing of an equation system and its solution. Here the term pre-processing refers to the steps required prior to solving a model in an equationoriented solution approach. The library is implemented in C...

Teladorsagia davtiani in sheep in the south-western Cape, is recorded in the Republic of South Africa for the first time. The literature dealing with this helminth is briefly reviewed.
