In terms of species-level diversity, the genus Crassula Linnaeus (1753: 282) is by far the most diverse in the Crassulaceae within the Flora of Southern Africa region [Namibia, Botswana, Eswatini (formerly Swaziland), Lesotho, South Africa] (Tölken 1977a, b, 1985). In this region diversity is highest in the Fynbos and Succulent Karoo Biomes, both of which straddle the southern Cape, an area represented in the Western and Eastern Cape provinces.

Economic Zones

The successful use of special economic zones as economic tools for export-led industrial development in East Asia propelled a wave of similar initiatives across Africa. In Southern Africa, Zambia and South Africa instituted special economic zones in their respective legal and institutional frameworks in the 2000s as mechanisms for catalysing industrialization and employment creation by means of domestic and foreign investments. Using a case-study approach, we find that special economic zones in the Eastern Cape, South Africa, are largely latent drivers of growth and employment hampered by inadequate infrastructure financing and provision and weak local supplier capabilities. Special economic zones in Lusaka, Zambia, face similar constraints but are further hampered by inadequate business services provision, burdensome regulations and business procedures, a fragmented incentive framework, institutional coordination failures, and a weak design that does not leverage strategic anchor industries for greater agglomeration economies, thus rendering them more of white elephants.

Abstract In the Flora of southern Africa area, comprising the countries of South Africa, Namibia, Botswana, Lesotho and Swaziland, the moss family Sematophyllaceae consists of three genera (Trichosteleum, Donnellia and Sematophyllum) and nine species. Core sematophyllous taxa with collenchymatous exothecial cells, long rostrate operculum, linear leaf cells and differentiated alar cells are included in the family. Meiothecium fuscescens is transferred to Donnellia and a new combination made. Sematophyllum wageri is reduced to synonymy under S. brachycarpum and a lectotype is designated for S. dregei. Each species is described and its distribution mapped.

Phoberus ntlenyanae Strümpher, new species is described from Lesotho and South Africa and is placed in the southern African Phoberus caffer group of species. The P. caffer species group is redefined to include the new species. One taxonomic status change is proposed: Phoberus lilianae (Scholtz, 1980) from the Eastern Highlands of Zimbabwe and the eastern escarpment of South Africa is elevated to species level. Phoberus caffer (Harold, 1872) is recorded for the first time from Eastern Cape and North West Province of South Africa. A key is provided for the identification of the members of the group. Photographs illustrate the species, and a map shows their geographical distributions. [Zoobank URL: urn:lsid:zoobank.org:act:0CB1BAD0-F9C2-4303-B746-487BCADF0D07]

History Of

The histories of the two swine fevers in southern Africa differ widely. Classical swine fever (hog cholera) has been known in the northern hemisphere since 1830 and it is probable that early cases of ‘swine fever’ in European settlers’ pigs in southern Africa were accepted to be that disease. It was only in 1921 that the first description of African swine fever as an entity different from classical swine fever was published after the disease had been studied in settlers’ pigs in Kenya. Shortly after that, reports of African swine fever in settlers’ pigs emerged from South Africa and Angola. In South Africa, the report related to pigs in the north-eastern part of the country. Previously (in 1905 or earlier) a disease assumed to be classical swine fever caused high mortality among pigs in the Western Cape and was only eradicated in 1918. African swine fever was found over the following years to be endemic in most southern African countries. Classical swine fever, however, apart from an introduction with subsequent endemic establishment in Madagascar and a number of introductions into Mauritius, the last one in 2000, had apparently remained absent from the region until it was diagnosed in the Western and subsequently the Eastern Cape of South Africa in 2005. It was eradicated by 2007. The history of these diseases in the southern African region demonstrates their importance and their potential for spread over long distances, emphasising the need for improved management of both diseases wherever they occur.

Hesperoides afromeridionalis gen. nov. and sp. nov. from the Republic of South Africa (Western and Eastern Cape Provinces and KwaZulu-Natal) is described. Despite some similarities with Hespera Weise, it exhibits major affinities with the genera attributed to the subtribe Aphthonini, especially with Aphthona Chevrolat and Montiaphthona Scherer. Data on distribution are supplied, along with preliminary ecological notes. Photomicrographs of main morphological characters, including male and female genitalia, and metafemoral extensor tendon are provided. Key to the six “hairy” flea beetle genera occurring in sub-Saharan African and their habitus photos are also given.

There are three major mollusc collections in South Africa and seven smaller, thematic collections. The KwaZulu-Natal Museum holds one of the largest collections in the southern hemisphere. Its strengths are marine molluscs of southern Africa and the southwestern Indian Ocean, and terrestrial molluscs of South Africa. Research on marine molluscs has led to revisionary papers across a wide range of gastropod families. The Iziko South African Museum contains the most comprehensive collections of Cephalopoda (octopus, squid and relatives) and Polyplacophora (chitons) for southern Africa. The East London Museum is a provincial museum of the Eastern Cape. Recent research focuses on terrestrial molluscs and the collection is growing to address the gap in knowledge of this element of biodiversity. Mollusc collections in South Africa date to about 1900 and are an invaluable resource of morphological and genetic diversity, with associated spatial and temporal data. The South African National Biodiversity Institute is encouraging discovery and documentation to address gaps in knowledge, particularly of invertebrates. Museums are supported with grants for surveys, systematic studies and data mobilisation. The Department of Science and Innovation is investing in collections as irreplaceable research infrastructure through the Natural Science Collections Facility, whereby 16 institutions, including those holding mollusc collections, are assisted to achieve common targets and coordinated outputs.

Background: The dwarf succulent genus Conophytum N.E.Br. is one of the most species rich in the Aizoceae. The genus is most closely associated with a region of high floral endemism and biodiversity, the Succulent Karoo biome in south-western Africa.Objectives: To examine the distribution of Conophytum in south-western Namibia and in the Northern and Western Cape Provinces of South Africa.Method: A database comprising 2798 locality records representing all known species and subspecies of the genus Conophytum has been constructed.Results: The genus is primarily restricted to the arid winter-rainfall region of the Northern and Western Cape Provinces of South Africa and south-western Namibia, within the Greater Cape Floristic Region. Whilst taxa are found across all the main biomes in the region (the Succulent Karoo, Nama Karoo, Desert and Fynbos biomes), 94% of Conophytum taxa are found only in the Succulent Karoo biome and predominantly (88% of taxa) within South Africa. Endemism within specific bioregions is a feature of the genus and ~60% of taxa are endemic to the Succulent Karoo. Approximately 28% of all taxa could be considered point endemics. Whilst the genus has a relatively wide geographical range, we identify a pronounced centre of endemism in the southern Richtersveld.Conclusion: The genus Conophytum can be used as a good botanical model for studying patterns of diversity and speciation in the Succulent Karoo biome, the effects of climate change on dwarf succulents, and for informing conservation planning efforts.
