    The diet of the ragged-tooth shark <em>Carcharias taurus</em> Rafinesque 1810 in the Eastern Cape, South Africa

    Item type: Journal Article • Journal: African Journal of Marine Science
    The ragged-tooth shark Carcharias taurus is a large predator of inshore coastal waters in the Eastern Cape, South Africa. Born at about 1m long and attaining approximately 3m, stomach content analyses have shown that it feeds largely on teleosts and...
  2. Genomic resources for the spotted ragged-tooth shark <em>Carcharias taurus</em>

    Genomic resources for the spotted ragged-tooth shark <em>Carcharias taurus</em>

    Item type: Journal Article • Journal: African Journal of Marine Science
    Genomic data can be a useful tool in the management and conservation of biodiversity. Here, we report the development of genomic resources for the spotted ragged-tooth shark Carcharias taurus using genome-wide DNA data from Illumina next-generation sequencing. We explored two...
  3. The economic benefits of fungicide treatment of maize for the control of grey leaf spot (<em>Cercospora zeae-maydis</em>) in KwaZulu-Natal

    The economic benefits of fungicide treatment of maize for the control of grey leaf spot (<em>Cercospora zeae-maydis</em>) in KwaZulu-Natal

    Item type: Journal Article • Journal: South African Journal of Plant and Soil
    Grey leaf spot (Cercospora zeae-maydis Tehon and E.Y. Daniels) is a relatively new disease of maize in South Africa and is capable of reducing grain yields by 20–60% in KwaZulu-Natal. Fungicides are widely used for control, but must be applied...
  4. Susceptibility of maize hybrids to grey leaf spot under two tillage systems in South Africa

    Susceptibility of maize hybrids to grey leaf spot under two tillage systems in South Africa

    Item type: Journal Article • Journal: South African Journal of Plant and Soil
    Grey leaf spot (Cercospora zeae-maydis Tehon and E.Y. Daniels) has seriously decreased the yields of maize in KwaZulu-Natal, South Africa, and has been identified in neighbouring provinces and countries. Since no commercially grown hybrids have been identified to be resistant...
  5. Analysis of Spray Aid's residue curve for timing fungicide applications for grey leaf spot on maize

    Analysis of Spray Aid's residue curve for timing fungicide applications for grey leaf spot on maize

    Item type: Journal Article • Journal: South African Journal of Plant and Soil
    Maize grey leaf spot is still a problem in commercial maize production, although the effect has been reduced with the widespread use of resistant varieties. It is estimated that, with a yield reduction of 1 %, annual economic losses of...
  6. Age and growth of the spinner shark <em>Carcharhinus brevipinna</em> (Müller and Henle, 1839) off the KwaZulu-Natal coast, South Africa

    Age and growth of the spinner shark <em>Carcharhinus brevipinna</em> (Müller and Henle, 1839) off the KwaZulu-Natal coast, South Africa

    Item type: Journal Article • Journal: South African Journal of Marine Science
    Age and growth of the spinner shark Carcharhinus brevipinna off the KwaZulu-Natal coast of South Africa was investigated from vertebral growth ring counts of 67 specimens (54–213 cm precaudal length, PCL). Counts were made from sectioned vertebral centra by two...
  7. The influence of organic mulches on soil temperatures with the establishment of Smuts finger and white buffalo grasses on a vertic soil

    The influence of organic mulches on soil temperatures with the establishment of Smuts finger and white buffalo grasses on a vertic soil

    Item type: Journal Article • Journal: African Journal of Range & Forage Science
    Fine‐seeded grasses are established with great difficulty, especially on heavy clay soil, but the literature suggests that organic mulches may counteract constraining soil factors which result in poor germination. Various organic mulches were used in this study in order to...

    A pilot study to determine the profile of recovery room nurses in Johannesburg hospitals

    Item type: Journal Article • Journal: Southern African Journal of Anaesthesia and Analgesia
    Background: Apart from anecdotal evidence, very little is known of the recovery room nurses in South Africa.

    Participatory action research in the training of primary health care nurses in Venda

    Item type: Journal Article • Journal: South African Family Practice
    Background: The aim of this study was to understand and be part of a process of change in the training of primary health care nurses in Venda.
