  1. The effect of fire history on soil nutrients and soil organic carbon in a semi-arid savanna woodland, central Namibia

    The effect of fire history on soil nutrients and soil organic carbon in a semi-arid savanna woodland, central Namibia

    Item type: Journal Article • Journal: African Journal of Range & Forage Science
    Fire is an integral part of savanna ecosystems that has shaped these systems since the Miocene. Substantial uncertainty about fire effects in semi-arid ecosystems exists. Fire may affect ecosystem productivity directly through nutrient volatilisation, increased mineralisation and altering organic matter...
  2. Male youth talk in the construction of black lesbian identities

    Male youth talk in the construction of black lesbian identities

    Item type: Journal Article • Journal: Southern African Linguistics and Applied Language Studies
    This study focuses on young black lesbians’ use of male township youth's ways of talking. Data come from ethnographic work among four lesbians in a township near Mafikeng, the capital city of North-West province in South Africa. Our analysis draws...
  3. A social history of urban male youth varieties in Stirtonville and Vosloorus, South Africa

    A social history of urban male youth varieties in Stirtonville and Vosloorus, South Africa

    Item type: Journal Article • Journal: Southern African Linguistics and Applied Language Studies
    Informal male youth varieties are a widespread phenomenon of township life across South Africa. A common view is that there are two varieties with separate origins: a Bantu language-based variety, called Iscamtho, and an Afrikaans-based variety called Tsotsitaal that has...
  4. Insights into the feeding ecology of the Seychelles Black Parrot <em>Coracopsis barklyi</em> using two monitoring approaches

    Insights into the feeding ecology of the Seychelles Black Parrot <em>Coracopsis barklyi</em> using two monitoring approaches

    Item type: Journal Article • Journal: Ostrich: Journal of African Ornithology
    Feeding ecology is an important factor for the survival of a species and knowledge of its parameters is a prerequisite for successful conservation work. In this study we describe the feeding ecology of the endemic Seychelles Black Parrot Coracopsis barklyi...
  5. Breeding ecology of the Seychelles Black Parrot <em>Coracopsis barklyi</em>

    Breeding ecology of the Seychelles Black Parrot <em>Coracopsis barklyi</em>

    Item type: Journal Article • Journal: Ostrich: Journal of African Ornithology
    Knowledge of breeding ecology is required for many conservation interventions. The Seychelles Black Parrot Coracopsis barklyi, endemic to the island of Praslin, is vulnerable to extinction. We aimed to improve understanding of C. barklyi breeding ecology to aid conservation planning...
  6. Survey of gastrointestinal parasite infection in African lion (<em>Panthera leo</em>), African wild dog (<em>Lycaon pictus</em>) and spotted hyaena (<em>Crocuta crocuta</em>) in the Luangwa Valley, Zambia

    Survey of gastrointestinal parasite infection in African lion (<em>Panthera leo</em>), African wild dog (<em>Lycaon pictus</em>) and spotted hyaena (<em>Crocuta crocuta</em>) in the Luangwa Valley, Zambia

    Item type: Journal Article • Journal: African Zoology
    Little is known about gastrointestinal parasite infections in large carnivores in Africa and what is available is largely from East Africa. We collected faecal samples from nine spotted hyaenas (Crocuta crocuta), 15 lions (Panthera leo) and 13 African wild dog...
  7. Adaptations to life on arid islands of South Africa: renal performance and phenotypic plasticity in the European rabbit <em>Oryctolagus cuniculus</em>

    Adaptations to life on arid islands of South Africa: renal performance and phenotypic plasticity in the European rabbit <em>Oryctolagus cuniculus</em>

    Item type: Journal Article • Journal: African Zoology
    Morphological parameters of the mammalian kidney can provide information on the extent to which an animal is able to regulate water relations within its body and cope with arid conditions. Certain groups of mammals, such as rabbits and hares, show...
  8. Laryngotracheal and cervical muscular anatomy in the genus <em>Uroplatus</em> (Gekkota: Gekkonidae) in relation to distress call emission

    Laryngotracheal and cervical muscular anatomy in the genus <em>Uroplatus</em> (Gekkota: Gekkonidae) in relation to distress call emission

    Item type: Journal Article • Journal: African Journal of Herpetology
    The gekkonid Uroplatus exhibits many autapomorphic features. The laryngotracheal region has long been noted to display unusual characteristics, with a widely expanded and membrane-roofed anterior portion of the trachea being prominent among these. It has been proposed that this tracheal...
  9. The impact of cerebrospinal fluid viral analysis on empiric antibiotic use in children admitted to Tygerberg Children’s hospital with suspected meningitis

    The impact of cerebrospinal fluid viral analysis on empiric antibiotic use in children admitted to Tygerberg Children’s hospital with suspected meningitis

    Item type: Journal Article • Journal: Southern African Journal of Infectious Diseases
    Background: Viral meningitis is the most common form of aseptic meningitis and requires minimal investigation and treatment. Polymerase chain reaction (PCR) has become the ‘gold standard’ for identifying viruses in cerebrospinal fluid and can provide rapid results. The objective of...
