  2. Genetic structure of wild and domesticated grasscutters (<em>Thryonomys swinderianus</em>) from south-western Nigeria

    Genetic structure of wild and domesticated grasscutters (<em>Thryonomys swinderianus</em>) from south-western Nigeria

    Item type: Journal Article • Journal: African Zoology
    Grasscutter (Thryonomys swinderianus) is a large rodent distributed across sub-Saharan Africa that is highly valued as a source of protein. There has been little effort to evaluate the genetic structure of grasscutters despite long-term harvesting pressure and over 40 years...
  3. The Response of <em>Pinus radiata</em> to Manganese Applications at the Ruitersbos State Forest

    Item type: Journal Article • Journal: South African Forestry Journal
    Although ranked as a minor nutritional problem when compared to the serious phosphate shortages in the Cape forest regions, manganese deficiencies are recorded from time to time, and growth losses have been recorded in P. radiata. Species such as P...
  4. Sequential estimation of forage dry matter <em>in situ</em> under rapidly changing conditions

    Sequential estimation of forage dry matter <em>in situ</em> under rapidly changing conditions

    In rapidly changing conditions repeated calibration of the pasture disc meter is necessary for reasonably accurate estimates of standing forage. Estimates of dry matter yield determined from the disc height of the meter depend on many factors, mainly disc height...
  5. Methods of capture and transfer to the laboratory of wild pelagic fish

    Methods of capture and transfer to the laboratory of wild pelagic fish

    Item type: Journal Article • Journal: South African Journal of Marine Science
    Two successful methods of capturing anchovy, pilchard and other pelagic fish and transporting them to the laboratory are described.
  6. A note on the incidence and treatment of a bacterial infection of wild pelagic fish maintained in the laboratory

    A note on the incidence and treatment of a bacterial infection of wild pelagic fish maintained in the laboratory

    Item type: Journal Article • Journal: South African Journal of Marine Science
    The pathogens of an eye infection affecting capture-stressed pelagic fish were isolated and identified. Prophylactic use of veterinarian tetracycline was found to be an effective treatment.
  7. Methods of presenting intercropping results and preliminary results with <em>Zea mays</em> and <em>Phaseolus vulgaris</em>

    Methods of presenting intercropping results and preliminary results with <em>Zea mays</em> and <em>Phaseolus vulgaris</em>

    Item type: Journal Article • Journal: South African Journal of Plant and Soil
    Replacement intercropping trials with maize and dry beans were conducted to provide information which could lead to a cropping strategy that would reduce the risk of rainfed crop production in the Ciskei. Attention is focused on the problem of analysing...
