“…The coast west of Cape Recife is typified by jagged rocks of quartzitic sandstone, with numerous pools and gullies whilst within Algoa Bay, from Cape Recife to Flat Rocks, a gently sloping rock platform of calcareous sandstone, incised by pools occurs (Stephenson, Stephenson & Bright 1938;Mclachlan, Lombard & Lourens 1981). Semidiurnal tides occur in the study area and have a mean range of 1,61 m at springs and 0,51 mat neaps (Beckley & Mclachlan 1979).…”

Fish occurring in tidal pools in the lower balanoid zone near Port Elizabeth were examined by visual census and rotenone collections. Numerically, Clinidae constituted 28% of the community, Sparidae 23%, Gobiidae 17% and the Cheilodactylidae 12%, while eleven other families contribut· ed to the remaining 20%. The 44 species recorded were classified as either residents (e.g. Clinidae or Gobiidae) or transients. The transient species were chiefly juvenile Sparidae, Cheilodactylidae and Mugilidae although numerous tropical vagrants also occurred in the summer months. Tidal pools, when compared with other coastal habitats, were found to be an important nursery area for some of the tran· sient species, particularly Sparodon durbanensis, Diplodus cervinus hottentotus, Chirodactylus brachydactylus and Cheilodactylus fasciatus. 8. Afr. J. Zool. 1985, 20: 21-27 Die visgemeenskappe van getypoele naby Port Elizabeth is deur middel van visuele sensusse asook vergiftingsmetodes bestudeer. Clinidae het tot 28% van die gemeenskap bygedra, Sparidae 23%, Gobiidae 17% en Cheilodactylidae 12% terwyl elf ander families tot die oorblywende 20% bygedra het. Vier-en-veertig spesies is gevang en word as permanente of tydelike inwoners geklassifiseer. Die tydelike spesies is hoofsaaklik klein Sparidae, Cheilodactylidae en Mugilidae alhoeweI tropiese swerwers in die somermaande voorkom.

“…Stephenson and co-workers, in their quest to identify a zonation scheme relevant to southern African shores, studied the distribution of marine organisms at eight different localities (Stephenson et al, 1937;Bright, 1938aBright, , 1938bEyre & Stephenson, 1938;Stephenson et al, 1938;Eyre, 1939;Stephenson et al, 1940). Observations made during these investigations were combined to produce a zonation scheme applicable to the entire southern African shore and to identify three biogeographical provinces (Stephenson, 1939(Stephenson, , 1944(Stephenson, , 1948.…”

The intertidal algal flora of Isipingo Beach, Natal, South Africa, and its phycogeographical affinities

The intertidal seaweed flora of Isipingo Beach, Natal, is described. Isipingo Beach hes on the sub-tropical east coast of southern Africa and is the only east coast locality studied in detail by pioneering biogeographers. A total of 172 species (37 chlorophytes, 26 phaeophytes and 109 rhodophytes) are recorded. A phycogeographical analysis of 124 species with sufficiently documented distributions, shows that 69 % are warm water species also known from the tropical coasts of Mozambique, Tanzania and Kenya. The phycogeographical affinity of the Isipingo flora is certainly with sub-tropical and tropical floras.

a b s t r a c t Edited by WA StirkKeywords: cox3 Diversity Indian Ocean ITS-2 mt23S Phylogeny RuBisCO Seaweeds Systematics A total of 27 different Sargassum epithets are listed in the literature for South Africa. The main aim of our study was to revise this species list using newly collected specimens in order to provide a reliable and illustrated tool for the identification of South African Sargassum. Based on morphological and molecular analyses of the nuclear ITS2, chloroplastic partial RuBisCO operon and mitochondrial cox3 and 23S, we identified a total of seven taxa including two new records (*) for South Africa: Sargassum elegans, Sargassum cymosum var. scabriusculum, Sargassum ilicifolium, Sargassum ilicifolium var. acaraeocarpum*, Sargassum incisifolium, Sargassum obovatum and, Sargassum polycystum*. As a result of our taxonomic revision, we conclude that a number of the species listed in the literature for South Africa were misapplied or not current and we propose five new taxonomic synonyms. We provide an exhaustive list of the Sargassum species present in South Africa, a key for identification and detailed illustrations.
