Planktonic and benthic invertebrates
AbstractNo particular emphasis has been placed on the study of planktonic or benthic invertebrate community structure in relation to biotic or abiotic conditions in southern African lakes and...
View ArticlePrimary producers and their production in lakes and reservoirs
AbstractPrimary (autotrophic) production data for the lakes of southern Africa are very limited. The largest data bases exist for Lake Sibaya and Swartvlei (Fig. 4.2a), with a much smaller record for...
View ArticleRiverine wetlands
AbstractThe wetlands of southern Africa are numerous and diverse, which might appear strange in a subcontinent where the general hydrological emphasis is largely upon its aridity and lack of natural...
View ArticleThe regional limnology of southern Africa
AbstractThe geomorphological, geochemical and climatological features of southern Africa define five limnological regions of the subcontinent. They are, from east to west: (Fig. 4.1a & b) A...
View ArticleBacteria and their activity in lakes and reservoirs
AbstractIn southern Africa there is a steadily increasing quantity of data on heterotrophic bacterial numbers and activity in reservoirs (see 12.2). In contrast, there are few bacterial data available...
View ArticleSuspensoids, hydrodynamics and chemical conditions in natural and man-made lakes
AbstractThe first serious study of the standing waters of southern Africa was that of Evelyn Hutchinson and his colleagues. They undertook an epic journey under extremely trying conditions, the...
View ArticleThe influence of man
AbstractNone of the major rivers, and few small streams in southern Africa have escaped some form of disturbance from Man’s influence. Those related to pollution have been reviewed earlier, so this...
View ArticleTypes of rivers and their characteristics
AbstractThe southern African region can be split into the well-watered tropical North, drained by major rivers such as the Zambezi and Okavango, and the water-limited South, of which the western side...
View ArticleThe climate
AbstractThe climatology of southern Africa has been reviewed by Schulze & McGee (1978) and Tyson (1986), while Preston-Whyte & Tyson (1988) have provided a very readable text describing the...
View ArticleIntroduction
AbstractAn assessment of the limnology of the sub-continent of southern Africa is overdue. In this particular perspective we have described the properties and behaviour of non-temperate water systems...
View ArticleUnique rivers
AbstractSome rivers, because of their length and the size of their catchments, present such a diversity of conditions, and because of the volume of their flow, constitute such different habitats from...
View ArticleFish and fisheries
AbstractRelatively long-lived organisms such as fish which lack dispersive life-history stages are constrained by the paucity of natural standing waters in southern Africa. Pans and lakelets tend to be...
View ArticleThe geomorphology of southern Africa
AbstractSince the separation of Africa from Gondwanaland (Fig. 2.1) the coastal rimland of the southern subcontinent has been subject to successive elevations and subsequent coastal abrasion. This...

AbstractThe effects of water infiltration into an alkaline coal combustion waste burial site on the chemical and microbiological aspects of a meso-scale (2.44 m diameter × 4.6 m, height, 65 tonne)...
View ArticleMicrobial exopolymers provide a mechanism for bioaccumulation of contaminants
AbstractScanning confocal laser microscopy was used to directly visualize accumulation of the herbicide diclofop methyl and its breakdown products by a degradative biofilm community, cultivated in...
View ArticleSpatial and temporal variability in lipid dynamics of common amphipods:...
A three-tiered approach involving autoradiography, measurement of seasonal lipid patterns and deployment of in situ microcosms, was used to assess the potential of the moderately lipophilic herbicide...
View ArticleIn situ Characterization of Biofilm Exopolymers Involved in the Accumulation...
AbstractThe chemical nature and spatial arrangements of exopolymers in a degradative biofilm community were studied using a panel of fluorescein isothiocyanate– and tetramethyl rhodamine...

AbstractExperiments were conducted to determine the limiting nutrient and the effect of pulp mill effluent (PME) on heterotrophic biofilms in the Fraser River, a northern, temperate river in British...

AbstractBecause of the large size of the former Soviet Union (FSU) and the heavy use of organochlorine pesticides (OCPs) in the FSU, usage information regarding OCPs in the FSU is important in...
