181. Issues in contemporary geographical hydrology - Hughes, D.A.
Finding solutions to the many water resource utilisation problems that face South Africa has been the driving force behind a large part of the hydrological research that has been undertaken in the country.

182. The importance of dry woodlands and forests in rural livelihoods and poverty alleviation in South Africa - Shackleton, C.M.; Shackleton, S.E.; Buiten, Erik; Bird, Neil
Indigenous forests and savannas, along with plantation forests, offer numerous benefits to rural communities and society at large.

183. Hydroclimatic trends, sediment sources and geomorphic response in the Bell River catchment, eastern Cape Drakensberg, South Africa - Dollar, E.S.J.; Rowntree, K.M.
The Bell River in the Eastern Cape Drakensberg of South Africa has shown recent signs of channel instability as evidenced by avulsion, sinuosity reductions, gradient steepening and general channel instability.

184. ‘Alternative foods’ and community-based development: Rooibos tea production in South Africa's West Coast Mountains - Nel, E.L.; Binns, T.; Bek, D.
Rooibos tee (red bush tea) (Aspalathus linearis, Fabaceae), which is indigenous only to the Cedarberg and neighbouring mountains of South Africa, has become popular internationally as a result of its apparent health-giving properties.

185. Oceanographic environment of the Sodwana Bay coelacanths (Latimeria chalumnae), South Africa - Roberts, M.J.; Ribbink, A.J.; Morris, T.; Van den Berg, M.A.; Engelbrecht, D.C.; Harding, R.T.
The existence of these animals at such a shallow depth and in the swift and powerful Agulhas Current led to a suggestion that this might be an isolated group swept well away from the main population in the Comoros, where they live at depths of 200–350 m with little current.

186. Fishes of the deep demersal habitat at Ngazidja (Grand Comoro) Island, Western Indian Ocean - Heemstra, P.C.; Hissmann, K.; Fricke, H.; Smale, M.J.; Schauer, J.
Underwater observations of the coelacanth, Latimeria chalumnae Smith, 1939, from a research submersible provided opportunities to study the deep demersal fish fauna at the Comoro Islands.

187. A Geographic Information System for the African Coelacanth Ecosystem Programme - Scott, L.E.P.
The African Coelacanth Ecosystem Programme (ACEP) Geographic Information System (GIS) has been developed to integrate, analyse and map all spatial data generated within the ACEP programme.

188. Molecular biology studies on the coelacanth: a review - Modisakeng, K.W.; Amemiya, C.T.; Dorrington, R.A.; Blatch, G.L.
The discovery of the African coelacanth in 1938 and subsequently the Indonesian coelacanth in 1998 has resulted in a keen interest in molecular studies on the coelacanth.

189. Interactions of fishes with particular reference to coelacanths in the canyons at Sodwana Bay and the St Lucia Marine Protected Area of South Africa - Heemstra, P.C.; Fricke, H.; Hissmann, K.; Schauer, J.; Smale, M.; Sink, K.
The deep demersal fish fauna at depths of 100–400min canyons off the St Lucia Marine Protected Area along the north coast of KwaZulu-Natal is compared with similar fish communities at the Comoro Islands and in the Indo-Pacific region.

190. 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.

191. Automated estimation and analyses of meteorological drought characteristics from monthly rainfall data - Smakhtin, V.U.; Hughes, D.A.
They include the Decile Index (DI), the Effective Drought Index (EDI), the Standardized Precipitation Index (SPI) and deviations from the long-term mean and median value.

192. World views, joking and liberated women - some reflections on the application of kinship theory - Whisson, M.G.

193. 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.

194. 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.

195. 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.

196. Changes in fuelwood use and selection following electrification in the Bushbuckridge lowveld, South Africa - Madubansi, M.; Shackleton, C.M.
Fuelwood is the primary energy source for domestic purposes throughout the developing world, in both urban and rural environments.

197. 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?].

198. Palynology and palaeo-environment of Pleistocene hyaena coprolites from an open-air site at Oyster Bay, Eastern Cape coast, South Africa. - Carrion, J.S.; Brink, J.S.; Scott, L.; Binneman, J.N.F.
Pollen assemblages in the coprolites were dominated by Myrica and, to a lesser extent, Stoebe-Elytropappus type and Poaceae.

199. Increasing convergence between the recognition of an intangible asset for financial accounting purposes and strategic management accounting and project management techniques - Seyfert, W.; Roseberg, D.; Stack, E.M.
New management techniques such as 'just-in-time', 'lean manufacturing' and 'Six Sigma' allow managment accountants to shift their focus from the management and control of production processes to the management of strategic issues.
