  1. A REVIEW OF THE MACROBENTHIC FAUNA OF THE MHLATHUZE ESTUARY: SETTING THE ECOLOGICAL RESERVE

    A REVIEW OF THE MACROBENTHIC FAUNA OF THE MHLATHUZE ESTUARY: SETTING THE ECOLOGICAL RESERVE

    Item type: Journal Article • Journal: Southern African Journal of Aquatic Sciences
    This paper reviews historical and current ecological information on macrobenthos from the Mhlathuze Estuary before and after development of the Richards Bay Harbour. The fauna is described in terms of the potential influence of a change in freshwater inflow to...
  2. Assessing and monitoring rangeland condition in extensive pastoral regions using satellite remote sensing and GIS techniques: An application to the Ceres Karoo region of South Africa

    Assessing and monitoring rangeland condition in extensive pastoral regions using satellite remote sensing and GIS techniques: An application to the Ceres Karoo region of South Africa

    Item type: Journal Article • Journal: African Journal of Range & Forage Science
    The purpose of this paper is to describe the use of satellite remote sensing and GIS techniques in applying a localised range condition assessment methodology based on fence‐line contrasts. The approach was to compute six dissimilarity indices for data on...
  3. Available information on macroinvertebrates of the Mhlathuze coastal lakes: setting the ecological reserve (lake water requirements)

    Available information on macroinvertebrates of the Mhlathuze coastal lakes: setting the ecological reserve (lake water requirements)

    Item type: Journal Article • Journal: African Journal of Aquatic Science
    This paper reviews current information on the macroinvertebrates of four coastal lakes in the Mhlathuze catchment of Zululand. The fauna are described in terms of the potential influence of lake level changes in response to increasing anthropogenic pressures for available...
  4. Turning the Big Mac Index into the Medical MAC Index

    Turning the Big Mac Index into the Medical MAC Index

    Item type: Journal Article • Journal: Southern African Journal of Anaesthesia and Analgesia
    Objective: The purpose of this study was to create a global medical earnings index, called the Medical MAC Index, to enable a comparison of what medical specialists earn in the countries included in the study.
  5. Industrial Implementation of High Humidity Orientated Schedules in the Drying of Young 25 mm <em>E. grandis</em> Boards.

    Item type: Journal Article • Journal: South African Forestry Journal
    A high humidity orientated drying schedule has been developed for industrial kiln drying from green of 25 mm thick young E. grandis timber. Compared to a more conventional drying approach, total drying degrade with the use of the former is...
  6. A PSYCHODYNAMIC UNDERSTANDING OF TRAUMA AND ADOLESCENCE—A CASE STUDY

    A PSYCHODYNAMIC UNDERSTANDING OF TRAUMA AND ADOLESCENCE—A CASE STUDY

    This paper explores the unique ways in which trauma affects adolescents as opposed to children and/or adults. This is an area of research that has not received sufficient attention. The various approaches in defining the concept of trauma are outlined...
  7. Intrusion of beach-disposed dredger spoil into the Mhlathuze Estuary, South Africa, and its impact on <em>Zostera capensis</em>

    Intrusion of beach-disposed dredger spoil into the Mhlathuze Estuary, South Africa, and its impact on <em>Zostera capensis</em>

    Item type: Journal Article • Journal: African Journal of Aquatic Science
    Port expansion at Richards Bay on the east coast of South Africa between 1996 and 1999 required the disposal of some 5,998,429 m3 of dredge spoil. This was deposited via a pipeline onto the adjacent beach and spilled into the...
  8. The Environmental Reserve and its role in retaining the diversity of birds at the Thukela Estuary

    The Environmental Reserve and its role in retaining the diversity of birds at the Thukela Estuary

    Item type: Journal Article • Journal: Ostrich: Journal of African Ornithology
    In 1998, a new Water Act was promulgated in South Africa. The basic premise of the Act is that a river and its associated estuary are recognised as having a legitimate right to water as a resource. These aquatic ecosystems...
  9. Distribution and feeding modes of macrobenthos within three oceanographic feature areas of the KwaZulu-Natal Bight, South Africa

    Distribution and feeding modes of macrobenthos within three oceanographic feature areas of the KwaZulu-Natal Bight, South Africa

    Item type: Journal Article • Journal: African Journal of Marine Science
    The composition and distribution of macrobenthic communities was investigated in three areas in the KwaZulu- Natal Bight, a section of shelf off the east coast of South Africa. Areas were pre-selected on the basis of three known oceanographic features, posited...
  10. Unconsolidated sediment distribution patterns in the KwaZulu-Natal Bight, South Africa: the role of wave ravinement in separating relict versus active sediment populations

    Unconsolidated sediment distribution patterns in the KwaZulu-Natal Bight, South Africa: the role of wave ravinement in separating relict versus active sediment populations

    Item type: Journal Article • Journal: African Journal of Marine Science
    This paper examines the distribution of unconsolidated sediment in the KwaZulu-Natal Bight located along the east coast of South Africa. Results show that there is a general shelf-wide sediment distribution of coarser grain sizes between depths of 60 and 100 m,...
