  1. Reviewing evidence of marine ecosystem change off South Africa

    Reviewing evidence of marine ecosystem change off South Africa

    Item type: Journal Article • Journal: African Journal of Marine Science
    Recent changes have been observed in South African marine ecosystems. The main pressures on these ecosystems are fishing, climate change, pollution, ocean acidification and mining. The best long-term datasets are for trends in fishing pressures but there are many gaps,...
  2. Clay-substrate application to sandy open-cast mine soils

    Clay-substrate application to sandy open-cast mine soils

    Item type: Journal Article • Journal: South African Journal of Plant and Soil
    The review gives some insight into the objective of amelioration to improve fertility of sandy soils. The research concept is based on the high water and cation exchange capacity of clay minerals. Technological and economic problems as well as practicable...
  3. Germination strategies of Strandveld Succulent Karoo plant species for revegetation purposes: III Effect of relative humidity and storage site on seed viability

    Germination strategies of Strandveld Succulent Karoo plant species for revegetation purposes: III Effect of relative humidity and storage site on seed viability

    Item type: Journal Article • Journal: South African Journal of Plant and Soil
    Changes in seed viability owing to fluctuations in environmental conditions (temperature and relative humidity) are crucial factors to consider during post-mining revegetation efforts in the Strandveld Succulent Karoo. The effect of relative humidity and storage site on seed viability was...
  4. Spatial distribution of selected chemical properties of soils situated close to an abandoned manganese mine

    Spatial distribution of selected chemical properties of soils situated close to an abandoned manganese mine

    Item type: Journal Article • Journal: South African Journal of Plant and Soil
    This study aimed at understanding the spatial distribution of the base saturation percentage (PSB), cation exchange capacity (CEC), pH(water) and electrical conductivity (EC) in soils situated close to the abandoned Kgwakgwe Mn oxide ore mine, Botswana. Four hundred soil samples...
  5. DUNE MINING AND THE NHLABANE SYSTEM: CAN BIODIVERSITY AND THE NURSERY FUNCTION BE MAINTAINED?

    DUNE MINING AND THE NHLABANE SYSTEM: CAN BIODIVERSITY AND THE NURSERY FUNCTION BE MAINTAINED?

    Item type: Journal Article • Journal: Southern African Journal of Aquatic Sciences
    A four year study of the Nhlabane Estuary and Lake System was undertaken over the period 1992 to 1995. Data gathered clearly showed that in terms of ichthyofauna, the estuary plays an important role as a nursery ground for juveniles...
  6. Gastropod distribution in Lakes George and Edward, Uganda, relative to copper and cobalt levels

    Gastropod distribution in Lakes George and Edward, Uganda, relative to copper and cobalt levels

    Item type: Journal Article • Journal: African Journal of Aquatic Science
    Published data show that Lake George, Uganda, has a poorer gastropod fauna than Lake Edward, to which it is connected through the Kazinga Channel. We conducted a study in 2001 to test whether this could be linked to copper (Cu)...
  7. Pre-commercial Thinning of <em>Eucalyptus grandis</em> for Mining Timber Production

    Item type: Journal Article • Journal: South African Forestry Journal
    Eucalyptus grandis was thinned before a commercial yield could be expected. in an attempt to narrow the distribution of diameters and so raise the proportion of timber within mining timber standards. It IS shown that a mid-rotation thinning will not...
  8. Large-scale spatial patterns within soft-bottom epibenthic invertebrate assemblages along the west coast of South Africa, based on the <em>Nansen</em> trawl survey

    Large-scale spatial patterns within soft-bottom epibenthic invertebrate assemblages along the west coast of South Africa, based on the <em>Nansen</em> trawl survey

    Item type: Journal Article • Journal: African Journal of Marine Science
    Knowledge of benthic invertebrate biodiversity and distribution patterns over the continental shelf of South Africa is poor and this is hampering efforts to design a network of marine protected areas aimed at conserving regional benthic biota. We analysed invertebrate biodiversity...
  9. Growth, productivity, and scientific impact of sources of HIV/AIDS research information, with a focus on eastern and southern Africa

    Growth, productivity, and scientific impact of sources of HIV/AIDS research information, with a focus on eastern and southern Africa

    Item type: Journal Article • Journal: African Journal of AIDS Research
    As channels of communicating HIV/AIDS research information, serial publications and particularly journals are increasingly used in response to the pandemic. The last few decades have witnessed a proliferation of sources of HIV/AIDS-related information, bringing many challenges to collection-development librarians as...
  10. Bridging the gap between VCT and HIV/AIDS treatment uptake: perspectives from a mining-sector workplace in South Africa

    Bridging the gap between VCT and HIV/AIDS treatment uptake: perspectives from a mining-sector workplace in South Africa

    Item type: Journal Article • Journal: African Journal of AIDS Research
    This qualitative study sought to understand users' perceptions of the voluntary counselling and testing (VCT) and HIV-treatment services offered by a mining company in South Africa, with the intention of making recommendations to improve the rates of uptake. A purposive...
