  1. Long-term livestock grazing increases the recruitment success of epigeal termites: insights from a >75-year grazing experiment in the Karoo, South Africa

    Long-term livestock grazing increases the recruitment success of epigeal termites: insights from a >75-year grazing experiment in the Karoo, South Africa

    Item type: Journal Article • Journal: African Journal of Range & Forage Science
    Epigeal termites alter ecosystem-level processes through foraging and mound building. These effects are proportional to density. Whilst much is known about the factors influencing mound density in natural settings, how termites respond to livestock grazing has been overlooked. We compared...
  2. 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...
  3. 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.
  4. 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.

  6. SOME MODULES OVER A B*-ALGEBRA

    SOME MODULES OVER A B*-ALGEBRA

    Item type: Journal Article • Journal: Quaestiones Mathematicae
    Some modules, ℓp (B) (1 < p < ∞), over a commutative B*-alge= bra with identity are discussed and these are seen to have properties similar to the Banach spaces ℓp (1 < p < ∞).
