  1. The relationship between ENSO and rainfall and yield in the South African sugar industry

    The relationship between ENSO and rainfall and yield in the South African sugar industry

    Item type: Journal Article • Journal: South African Journal of Plant and Soil
    Information on the effects of El Nino on local climate and sugarcane production will assist planning and management. The objective of this study was to investigate the relationship between the southern oscillation index (SOI) and rainfall and sugarcane yields in...
  2. Using the Nearest Neighbour method to substitute missing daily solar radiation data

    Using the Nearest Neighbour method to substitute missing daily solar radiation data

    Item type: Journal Article • Journal: South African Journal of Plant and Soil
    Ground level solar radiation reflects the amount of energy that reaches the earth's surface and is utilised by people, animals and plants. Biological models often require such radiation records for long periods of time, however, a lack of radiation data...

    Modelling highly variable daily maximum water temperatures in a perennial South African river system

    Item type: Journal Article • Journal: African Journal of Aquatic Science
    Thirty-three months of observed hourly water temperatures were used to calculate daily maximum water temperatures for nine sites within the Sabie-Sand River system, Mpumalanga Province, South Africa. A suite of statistical models for simulating daily maximum water temperatures, of differing...
  6. Photosynthetic differences between <em>Microcystis aeruginosa</em> and <em>Oscillatoria simplicissima</em> in relation to species succession in the Vaal River, South Africa

    Photosynthetic differences between <em>Microcystis aeruginosa</em> and <em>Oscillatoria simplicissima</em> in relation to species succession in the Vaal River, South Africa

    Item type: Journal Article • Journal: African Journal of Aquatic Science
    In 1991 Oscillatoria simplicissima replaced Microcystis aeruginosa in the Vaal River, South Africa. This study explored the reason for this succession by looking at the photosynthetic performance of these two cyanoprokaryotes at different temperatures, light intensities and N:P ratios. Microcystis...
  7. A multidisciplinary study of a small, temporarily open/closed South African estuary, with particular emphasis on the influence of mouth state on the ecology of the system

    A multidisciplinary study of a small, temporarily open/closed South African estuary, with particular emphasis on the influence of mouth state on the ecology of the system

    Item type: Journal Article • Journal: African Journal of Marine Science
    In 2005/2006 a multidisciplinary research programme that included studies on the hydrodynamics, sediment dynamics, macronutrients, microalgae, macrophytes, zoobenthos, hyperbenthos, zooplankton, ichthyoplankton, fish and birds of the temporarily open/closed East Kleinemonde Estuary was conducted. Particular attention was given to the responses...
