The South African coelacanths — an account of what is known after three submersible expeditions - Hissmann, K.; Fricke, H.; Schauer, J; Ribbink, A.J.; Roberts, M.; Sink, K.; Heemstra, P.C.
Using the manned submersible Jago, the habits, distribution and number of coelacanths within all main submarine canyons of the Greater St Lucia Wetland Park were studied during 47 survey dives, with a total bottom time of 166 hours at depths ranging from 46 to 359 m, between 2002 and 2004.

A dinocephalian therapsid fauna on the Ecca–Beaufort contact in Eastern Cape Province, South Africa - Modesto, S.P.; Rubidge, B.S.; De Klerk, W.J.; Welman, J.
Systematic exploration of outcrops of the lowermost Beaufort Group for fossils of the oldest terrestrial vertebrates of South Africa, known only from the Permian age Eodicynodon Assemblage Zone in Western Cape Province, has resulted in the discovery of a therapsid fauna in Eastern Cape Province that is dominated by advanced dinocephalians.

Studying the impact of ocean eddies on the ecosystem of the Prince Edward Islands: DEIMEC ll - Pakhomov, E.A.; Ansorge, I.J.; Kaehler, S.; Vumazonke, L.U.; Gulekana, K.; Bushula, T.; Balt, C.; Paul, D.; Hargey, N.; Stewart, H.; Chang, N.; Furno, L.; Mkatshwa, S.; Visser, C.; Lutjeharms, J.R.E.; Hayes-Foley, P.
This island group consists of two small volcanic islands and provides many opportunities for studying ecological and evolutionary processes, for monitoring ecological changes in relation to global climate change and for conserving a unique component of the planet’s biological diversity.

Effect of water temperature on the biogeography of South African estuarine fishes associated with the subtropical/warm temperate subtraction zone. - Maree, R.C.; Booth, A.J.; Whitfield, A.K.
Qualitative and quantitative analyses were conducted upon the ichthyofaunal assemblages to determine whether the location of the subtropical/warm temperate boundary corresponds to that proposed by Whitfield.(n1) Analyses included the distribution ranges of species associated with estuaries according to presence/absence data, cluster analysis of gill net catches in eight estuaries along the southeastern coast and the relative proportion of tropical to temperate marine species within these eight systems.

Electrochemical characterisation of tetra- and octa-substituted oxo(phthalocyaninato)titanium(IV) complexes - Tau, P.; Nyokong, T.
The first two reductions are metal-based processes, confirmed by spectroelectrochemistry to be due to Ti[superscript IV]Pc[superscript 2?]/Ti[superscript III]Pc[superscript 2?] and Ti[superscript III]Pc[superscript 2?]/Ti[superscript II]Pc[superscript 2?] redox processes and the last two reductions are ring-based processes due to Ti[superscript II]Pc[superscript 2?]/Ti[superscript II]Pc[superscript 3?] and Ti[superscript II]Pc[superscript 3?]/Ti[superscript II]Pc[superscript 4?].

Patterns of sexual size dimorphism in African cichlid fishes. - Erlandsson, A.; Ribbink, A.J.
Disappointingly few authors published such measurements, so the data are fewer than anticipated given that the cichlids are such a species-rich group.

The evaluation of pharmaceutical pictograms in a low-literate South African population - Dowse, R.; Ehlers, M.
Twenty three pictograms from the USP-DI and a corresponding set of 23 locally developed, culturally sensitive pictograms for conveying medication instructions were evaluated in 46 Xhosa respondents who had attended school for a maximum of 7 years.

Improving the bioremediation of phenolic wastewaters by Trametes versicolor - Ryan, D.; Leukes, W.; Burton, S.
The successful bioremediation of a phenolic wastewater by Trametes versicolor was found to be dependent on a range of factors including: fungal growth, culture age and activity and enzyme (laccase) production.
