  1. Socio-economic and demographic factors related to HIV status in urban informal settlements in the Eastern Cape, South Africa

    Socio-economic and demographic factors related to HIV status in urban informal settlements in the Eastern Cape, South Africa

    Item type: Journal Article • Journal: African Journal of AIDS Research
    The prevalence of HIV&AIDS is embedded in social and economic inequity and the relationship between social determinants and HIV incidence is well established. The aim of this study was to determine which socio-economic and demographic factors are related to HIV...
  2. An alternative approach to veld condition assessment in the non‐grassveld regions of South Africa

    Item type: Journal Article • Journal: Journal of the Grassland Society of Southern Africa
    Traditional veld condition assessment methods score veld either in terms of its ‘state of health’ or its value for a specific land‐use objective. This is problematic and we propose that ‘veld condition’ should simply be a descriptive index, devoid of...
  3. Habitat preferences of twenty‐three grass species in the Bankenveld

    Item type: Journal Article • Journal: Journal of the Grassland Society of Southern Africa
    Some grass species occur more frequently in certain habitats than in others. There is, however, uncertainty as to exactly which factors are responsible for this phenomenon. Species composition as well as habitat data were collected from plots situated on the...
  4. 'n Vogstremmingsindeks vir gebruik in besproeiing van katoen

    'n Vogstremmingsindeks vir gebruik in besproeiing van katoen

    Item type: Journal Article • Journal: South African Journal of Plant and Soil
    Die behoefte bestaan om plantparameters as kritiese indikatore aan te wend om besproeiingsbestuur te vergemaklik. Die blaarwaterpotensiaal (ψb) van katoen en relatiewe turgiditeit (RT%) van blaarskyfies is gedurende 1983 tot 1985 en tydens die 1986/87-seisoen bepaal. Hierdie metings is op...
  5. THF DISTRIBUTION AND STATUS OF <em>KNERIA AURICULATA</em> (PELLEGRIN)(PISCES: KNERIIDAE) IN THE TRANSVAAL

    THF DISTRIBUTION AND STATUS OF <em>KNERIA AURICULATA</em> (PELLEGRIN)(PISCES: KNERIIDAE) IN THE TRANSVAAL

    Item type: Journal Article • Journal: Journal of the Limnological Society of Southern Africa
    The distribution of Kneria auriculata in the upper reaches of the Crocodile River (Incomati River System) was determined. Knevia auriculata shows a preference for cold mountain streams with calm pools. Five isolated populations exist in such streams. Although no accurate...
  6. HYDROCHEMISTRY OF THE UPPER ORANGE RIVER CATCHMENT

    HYDROCHEMISTRY OF THE UPPER ORANGE RIVER CATCHMENT

    Item type: Journal Article • Journal: Journal of the Limnological Society of Southern Africa
    A four year pre-impoundment study of the catchment of the Hendrik Verwoerd Dam was conducted. The Orange River was the major source of dissolved chemicals and suspended sediments, while the Caledon River contributed 24 and 30% respectively, and the Kraai...
  7. A PRELIMINARY LIMNOLOGICAL STUDY OF BUFFELSPOORT DAM AND ITS CATCHMENT

    A PRELIMINARY LIMNOLOGICAL STUDY OF BUFFELSPOORT DAM AND ITS CATCHMENT

    Item type: Journal Article • Journal: Journal of the Limnological Society of Southern Africa
    A limnological survey of the Buffelspoort Dam and its catchment between 1973 and 1975 showed that the water of the area contained extremely low concentrations of dissolved minerals and that there was no point source of nutrient supply to the...
  8. WATER TRANSPARENCY CHARACTERISTICS OF SOUTH AFRICAN IMPOUNDMENTS

    WATER TRANSPARENCY CHARACTERISTICS OF SOUTH AFRICAN IMPOUNDMENTS

    Item type: Journal Article • Journal: Journal of the Limnological Society of Southern Africa
    Some water transparency characteristics (Secchi disc transparency, mean diffuse light attenuation coefficient and turbidity) of a number of South African impoundments are compared. In general most impoundments may be considered to be highly turbid; for 92 impoundments considered in this...
  9. ZOOPLANKTON BIOMASS OF SOME TRANSVAAL IMPOUNDMENTS AND ITS RELATIONSHIP TO TROPHIC STATUS

    ZOOPLANKTON BIOMASS OF SOME TRANSVAAL IMPOUNDMENTS AND ITS RELATIONSHIP TO TROPHIC STATUS

    Item type: Journal Article • Journal: Journal of the Limnological Society of Southern Africa
    The zooplankton biomass characteristics of 11 South African impoundments were investigated to assess the value of zooplankton biomass as a trophic status index. Mean annual zooplankton biomasses ranged from 0,38 to 5,32 g m−2, compared with the mean annual chlorophyll...
  10. THE BARRED MINNOWS (TELEOSTEI: CYPRINIDAE) OF ZIMBABWE: IS THERE CAUSE FOR CONCERN?

    THE BARRED MINNOWS (TELEOSTEI: CYPRINIDAE) OF ZIMBABWE: IS THERE CAUSE FOR CONCERN?

    Item type: Journal Article • Journal: Southern African Journal of Aquatic Sciences
    Two species of barred minnow, Opsaridium zambezense and O. peringueyi, occur in Zimbabwe. The former is widely distributed in the Zambezi basin and some other rivers but is now absent from Lake Kariba and possibly some of its tributaries. The...
