- Description: The racialised regulation of space under apartheid was increasingly undone by insurgent popular action from the late 1970s. After apartheid a technocratic agenda that reduced the urban crisis to a housing crisis successfully depoliticised the urban question. At the same time the state made often violent attempts to reinscribe certain aspects of apartheid spatial logic by forcibly removing shack dwellers living in well located suburbs to tiny houses, and then later ‘transit camps’, in peripheral ghettoes. However from 2004 there was a remarkable sequence of popular protest against local governments across the country. An autonomous shack dweller’s movement, Abahlali baseMjondolo, emerged from this grassroots ferment and has since issued a compelling demand for organisational autonomy, grassroots urban planning and the right to the city.

- Description: Crabs of the family Hymenosomatidae are common in coastal and shelf regions throughout much of the southern hemisphere. One of the genera in the family, Hymenosoma, is represented in Africa and the South Pacific (Australia and New Zealand). This distribution can be explained either by vicariance (presence of the genus on the Gondwanan supercontinent and divergence following its break-up) or more recent transoceanic dispersal from one region to the other. We tested these hypotheses by reconstructing phylogenetic relationships among the seven presently-accepted species in the genus, as well as examining their placement among other hymenosomatid crabs, using sequence data from two nuclear markers (Adenine Nucleotide Transporter [ANT] exon 2 and 18S rDNA) and three mitochondrial markers (COI, 12S and 16S rDNA). The five southern African representatives of the genus were recovered as a monophyletic lineage, and another southern African species, Neorhynchoplax bovis, was identified as their sister taxon. The two species of Hymenosoma from the South Pacific neither clustered with their African congeners, nor with each other, and should therefore both be placed into different genera. Molecular dating supports a post-Gondwanan origin of the Hymenosomatidae. While long-distance dispersal cannot be ruled out to explain the presence of the family Hymenosomatidae on the former Gondwanan land-masses and beyond, the evolutionary history of the African species of Hymenosoma indicates that a third means of speciation may be important in this group: gradual along-coast dispersal from tropical towards temperate regions, with range expansions into formerly inhospitable habitat during warm climatic phases, followed by adaptation and speciation during subsequent cooler phases.
