  1. Use of the SDSS test to predict the protein content and bread volume of wheat cultivars

    Use of the SDSS test to predict the protein content and bread volume of wheat cultivars

    Item type: Journal Article • Journal: South African Journal of Plant and Soil
    The relationship between the sodium dodecyl sulphate sedimentation volume (SDSS test) and the protein content and bread volume of wheat cultivars was determined to ascertain whether the SDSS test could be used to predict these parameters of baking quality. This...
  2. FUNDUDZI, A UNIQUE, SACRED AND UNKNOWN SOUTH AFRICAN LAKE

    FUNDUDZI, A UNIQUE, SACRED AND UNKNOWN SOUTH AFRICAN LAKE

    Item type: Journal Article • Journal: Southern African Journal of Aquatic Sciences
    Lake Fundudzi is a unique, small inland lake in the north eastern region of South Africa, formed by a landslide. The considerable sedimentation of its basin indicates an age in the order of 10 000s of years. It forms the...
  3. Physico-chemical conditions and macroinvertebrate fauna in the River Nile from Aswan to Cairo

    Physico-chemical conditions and macroinvertebrate fauna in the River Nile from Aswan to Cairo

    Item type: Journal Article • Journal: African Journal of Aquatic Science
    This paper examines the distribution of benthic macroinvertebrates in relation to physico-chemical conditions along 1 035km of the River Nile from Aswan High Dam to Al Kanater Barrage, Cairo. Total Dissolved Salts and several individual chemical variables showed positive linear...
  4. Factors governing the removal of faecal indicator bacteria in the ecosystem of Lake Timsah, Egypt

    Factors governing the removal of faecal indicator bacteria in the ecosystem of Lake Timsah, Egypt

    Item type: Journal Article • Journal: African Journal of Aquatic Science
    Persistence of faecal coliforms, presumptive Vibrio cholerae and Vibrio parahaemolyticus at three stations in Lake Timsah were investigated in 2010. Samples were collected by day and at night. Bacterial counts were highest at the outlet of wastewater discharged into the...
  5. Road Building and the Survival of Indigenous Forest in the Southern Cape

    Item type: Journal Article • Journal: South African Forestry Journal
    The effects of road building activities on indigenous evergreen forest were investigated to quantify the impact, to provide guide-lines for minimising damage to forests during future road projects and to gain understanding of the response of different species. The investigation...
  6. Geomorphological and managerial implications of fish trapping in the Kosi Bay Estuary, KwaZulu-Natal, South Africa

    Geomorphological and managerial implications of fish trapping in the Kosi Bay Estuary, KwaZulu-Natal, South Africa

    Item type: Journal Article • Journal: African Journal of Marine Science
    The tidal basin of the Kosi Bay lagoonal-lacustrine complex is dominated by fish traps that line the intertidal and subtidal environments. These have been considered significant sediment sinks, responsible for transformation of parts of the system from subtidal and intertidal...
  7. Invasion of sandflats in Langebaan Lagoon, South Africa, by the alien mussel <em>Mytilus galloprovincialis</em>: size, composition and decline of the populations

    Invasion of sandflats in Langebaan Lagoon, South Africa, by the alien mussel <em>Mytilus galloprovincialis</em>: size, composition and decline of the populations

    Item type: Journal Article • Journal: African Zoology
    Since the 1980s the introduced Mediterranean mussel (Mytilus galloprovincialis) has successfully invaded the southern African coastline and has become the dominant species on rocky intertidal shores of the west coast. This study investigates a recent extension of its distribution into...
  8. Appraisal of access to safe drinking water in southwest Nigeria

    Appraisal of access to safe drinking water in southwest Nigeria

    The importance of developing effective water supply services is universally recognised as a basis for improving the overall health of the population. This study ascertained the quality of water supplied by a water treatment scheme in southwest Nigeria. One hundred...
  9. Land use change and its drivers in Kurt Bahir wetland, north-western Ethiopia

    Land use change and its drivers in Kurt Bahir wetland, north-western Ethiopia

    Item type: Journal Article • Journal: African Journal of Aquatic Science
    The effects of land-use change on ecosystem services in Kurt Bahir wetland were investigated during 2013 to 2014 using LANDSAT satellite images from 1973, 1986, 2002 and 2013 to identify and map changes in land-use classes over time. To understand...
  10. Sand-mediated divergence between shallow reef communities on horizontal and vertical substrata in the western Indian Ocean

    Sand-mediated divergence between shallow reef communities on horizontal and vertical substrata in the western Indian Ocean

    Item type: Journal Article • Journal: African Journal of Marine Science
    Distinctions are rarely made between vertical and horizontal surfaces when assessing reef community composition, yet physical differences are expected because of hydrodynamic differences and sediment accumulation on flat surfaces. As sand often diminishes biotic cover, we hypothesised that vertical surfaces...
