  1. Intraspecific host preferences of mopane moths (<em>Imbrasia belina</em>) in mopane (<em>Colophospermum mopane</em>) woodland

    Intraspecific host preferences of mopane moths (<em>Imbrasia belina</em>) in mopane (<em>Colophospermum mopane</em>) woodland

    Item type: Journal Article • Journal: African Zoology
    Colophospermum mopane trees are a common larval food plant of the mopane moth (Imbrasia belina),which commonly reaches outbreak proportions. Our study investigated factors determining host tree choice by ovipositing mopane moths within a single host species (C. mopane). Tree size...
  2. Effect of organic cultivation of rooibos tea plants (<em>Aspalathus linearis</em>) on soil nutrient status in Nieuwoudtville, South Africa

    Effect of organic cultivation of rooibos tea plants (<em>Aspalathus linearis</em>) on soil nutrient status in Nieuwoudtville, South Africa

    Item type: Journal Article • Journal: South African Journal of Plant and Soil
    The shoots of rooibos (Aspalathus linearis (Burm.f.) R.Dahlgren) plants, cultivated organically by small-scale farmers in Nieuwoudtville, are harvested for the production of tea. These practices could lead to decreasing soil fertility. It was hypothesised that soil from cultivated rooibos plots...
  3. The impacts of season and livestock management strategy on the quality of diets selected by goats and sheep in the semi-arid rangelands of Namaqualand, South Africa

    The impacts of season and livestock management strategy on the quality of diets selected by goats and sheep in the semi-arid rangelands of Namaqualand, South Africa

    Item type: Journal Article • Journal: African Journal of Range & Forage Science
    Access to good-quality forages is one of the major limitations to livestock production in semi-arid pastoral systems. This study aimed to determine whether there are differences in the nutritional quality of diets selected by herded and free-ranging goat and sheep...

    Knowledge, attitudes and sexual practices of adolescents with mild retardation, in relation HIV/AIDS

    Item type: Journal Article • Journal: African Journal of AIDS Research
    This study investigates the knowledge, attitudes and sexual practices of adolescents with mild mental retardation (MMR) in relation to HIV/AIDS. Questionnaires were personally administered to a saturation sample of 90 adolescents with MMR drawn from one specialised educational institution in...
  5. Laboratory-based surveillance of <em>Pneumocystis jirovecii</em> pneumonia in South Africa, 2006–2010

    Laboratory-based surveillance of <em>Pneumocystis jirovecii</em> pneumonia in South Africa, 2006–2010

    Item type: Journal Article • Journal: Southern African Journal of Infectious Diseases
    Background: We aimed to establish the characteristics of patients with confirmed Pneumocystis jirovecii pneumonia recruited by passive, sentinel laboratory-based surveillance.
  6. Comparison of infrared thermography and miniature Deltatron accelerometer sensors in the measurement of structural vibration characteristics

    Comparison of infrared thermography and miniature Deltatron accelerometer sensors in the measurement of structural vibration characteristics

    This paper investigates the comparison of infrared thermography (IRT) and miniature Deltatron accelerometer sensors in measuring structural vibration characteristics in terms of frequency and displacement, given that of age IRT has fully grown for temperature condition monitoring. In addition, IRT...
