  1. Population structure of the sicklefin lemon shark <em>Negaprion acutidens</em> within the Curieuse Marine National Park, Seychelles

    Population structure of the sicklefin lemon shark <em>Negaprion acutidens</em> within the Curieuse Marine National Park, Seychelles

    Item type: Journal Article • Journal: African Journal of Marine Science
    This study produced the first data on population parameters for sicklefin lemon shark Negaprion acutidens at the granitic Seychelles Islands, adding to a limited catalogue of species information. Juveniles at a site in the Curieuse Marine National Park were tagged...
  2. ‘Water and fertilizer influence on yield of grain sorghum varieties produced in Burkina Faso

    ‘Water and fertilizer influence on yield of grain sorghum varieties produced in Burkina Faso

    Item type: Journal Article • Journal: South African Journal of Plant and Soil
    Grain sorghum [Sorghum bicolor (L.) Moench] is the major cereal crop used in the Central Plateau of Burkina Faso to produce the traditional beer called “dolo”. Experiments combining five water management techniques (WMT) and four fertilizer treatments (FT) in a...
  3. Hydrocarbons in mussels around the Cape Peninsula, South Africa

    Hydrocarbons in mussels around the Cape Peninsula, South Africa

    Item type: Journal Article • Journal: South African Journal of Marine Science
    Two surveys of petroleum hydrocarbon levels in mussels around the Cape Peninsula have revealed that harbours are the major source of petroleum hydrocarbons. Other significant sources are industrial effluents and sewage. Levels in mussel tissue, as determined by fluorescence spectroscopy,...
  4. Accumulation and depuration of petroleum hydrocarbons by black mussels. 2. Depuration of field-exposed mussels

    Accumulation and depuration of petroleum hydrocarbons by black mussels. 2. Depuration of field-exposed mussels

    Item type: Journal Article • Journal: South African Journal of Marine Science
    Results of depuration studies of mussels collected from chronically polluted sites and those collected after a fuel oil spill tend to confirm laboratory-deduced indications that the rate of depuration decreases as the exposure time increases. Chronically polluted mussels lost their...
  5. Accumulation and depuration of petroleum hydrocarbons by black mussels. 1. Laboratory exposure trials

    Accumulation and depuration of petroleum hydrocarbons by black mussels. 1. Laboratory exposure trials

    Item type: Journal Article • Journal: South African Journal of Marine Science
    Laboratory experiments were conducted to measure the rates of accumulation and subsequent depuration of hydrocarbons by black mussels after exposure to various concentrations of water-soluble fractions of crude oil. The initial rate of uptake was related to the concentration in...
  6. Synoptic environment of composite tropical cyclones in the South-West Indian Ocean

    Synoptic environment of composite tropical cyclones in the South-West Indian Ocean

    Item type: Journal Article • Journal: South African Journal of Marine Science
    The composite structure of the tropical cyclone (TC) environment in the South-West Indian Ocean is analysed using European Community medium-range weather data. Conditions suitable for the development of tropical cyclones are present between 5 and 15°S and between 40 and...
  7. Fluvial Sediment Yield to the Natal Coast: A Review

    Fluvial Sediment Yield to the Natal Coast: A Review

    Item type: Journal Article • Journal: Southern African Journal of Aquatic Sciences
    Sediment yield is the quantitative expression of soil eroded from the hinterland and deposited in the ocean. This paper reviews existing literature available on sediment yields, particularly for the Natal coast, South Africa. Several authors have attempted to quantify the...

  10. Student Development and Support using a Logotherapeutic Approach

    Student Development and Support using a Logotherapeutic Approach

    Item type: Journal Article • Journal: Journal of Psychology in Africa
    This study reports on participants' meaning-centred experiences and perspectives after attending a logotherapy-based student development and support programme. Thirteen students who were enrolled in the first year of the academic programme, in health science programme at a South Africa university,...
