  1. Evidence of multiple divergent mitochondrial lineages within the southern African diplopod genus <em>Bicoxidens</em> Attems, 1928 (Spirostreptida)

    Evidence of multiple divergent mitochondrial lineages within the southern African diplopod genus <em>Bicoxidens</em> Attems, 1928 (Spirostreptida)

    Item type: Journal Article • Journal: African Zoology
    Two recent studies have suggested that divergent mitochondrial lineages may be present within spirostreptid genera such as Bicoxidens Attems, 1928. Bicoxidens, similar to many other endemic soil invertebrates, exhibits low dispersal capabilities and strict microclimate habitat preferences, attributes that often...
  2. Genetically distinct Dutch-domesticated <em>Clarias gariepinus</em> used in aquaculture in southern Africa

    Genetically distinct Dutch-domesticated <em>Clarias gariepinus</em> used in aquaculture in southern Africa

    Item type: Journal Article • Journal: African Journal of Aquatic Science
    Clarias gariepinus, a catfish species widely distributed in Africa including South Africa, is naturally absent from the Western Cape and the coastal Eastern Cape provinces. Because of its potential as an aquaculture species it has been widely used in aquaculture...
  3. <em>Conus pennaceus</em>: a phylogenetic analysis of the Mozambican molluscan complex

    <em>Conus pennaceus</em>: a phylogenetic analysis of the Mozambican molluscan complex

    Item type: Journal Article • Journal: African Journal of Marine Science
    The genus Conus has over 500 species and is the most species-rich taxon of marine invertebrates. Based on mitochondrial DNA, this study focuses on the phylogenetics of Conus, particularly the pennaceus complex collected along the Mozambican coast. Phylogenetic trees based...
  4. Evidence of hybridisation within the genus <em>Chrysoblephus</em> and conserved nuclear sequences of South African sparids (Teleostei: Sparidae)

    Evidence of hybridisation within the genus <em>Chrysoblephus</em> and conserved nuclear sequences of South African sparids (Teleostei: Sparidae)

    Item type: Journal Article • Journal: African Journal of Marine Science
    Several hybridisation events have been recorded in marine fish, yet there is little information for southern African species. Here we present evidence for hybridisation within the genus Chrysoblephus (Sparidae), by analysing a fish caught off KwaZulu-Natal, off the east coast...
  5. Phylogeographic structure of the caridean shrimp <em>Palaemon peringueyi</em> in South Africa: further evidence for intraspecific genetic units associated with marine biogeographic provinces

    Phylogeographic structure of the caridean shrimp <em>Palaemon peringueyi</em> in South Africa: further evidence for intraspecific genetic units associated with marine biogeographic provinces

    Item type: Journal Article • Journal: African Journal of Marine Science
    Recent genetic studies have shown that most widely distributed, passively dispersing invertebrates in southern Africa have regional intraspecific units that are associated with the three main marine biogeographic provinces (cool-temperate, warm-temperate and subtropical). The caridean shrimp Palaemon peringueyi also occurs...
  6. Long current to nowhere? — Genetic connectivity of <em>Jasus tristani</em> populations in the southern Atlantic Ocean

    Long current to nowhere? — Genetic connectivity of <em>Jasus tristani</em> populations in the southern Atlantic Ocean

    Item type: Journal Article • Journal: African Journal of Marine Science
    The commercially exploited spiny lobster Jasus tristani has a disjunct distribution in the southern Atlantic Ocean, with populations occurring at the Tristan da Cunha Archipelago, Gough Island and on Vema Seamount. A distance of 2 000km separates Vema and the...
  7. Phylogenetic relationships and genetic diversity of <em>Nemesis</em> Risso, 1826 species found on different elasmobranch host species off the KwaZulu-Natal coast, South Africa

    Phylogenetic relationships and genetic diversity of <em>Nemesis</em> Risso, 1826 species found on different elasmobranch host species off the KwaZulu-Natal coast, South Africa

    Item type: Journal Article • Journal: African Journal of Marine Science
    Members of the order Siphonostomatoida (Copepoda) are generally poorly described from South African waters. Nemesis is one of 12 genera in the family Eudactylinidae and includes about nine species. In this study, we investigated whether there is any population structure...
  8. The phylogenetic affinities of the Socotra Bunting <em>Emberiza socotrana</em>

    The phylogenetic affinities of the Socotra Bunting <em>Emberiza socotrana</em>

    Item type: Journal Article • Journal: Ostrich: Journal of African Ornithology
    The monophyly of the African ‘brown bunting’ complex was corroborated by a recent molecular study. However, the little-known Socotran endemic Emberiza socotrana, which is morphologically similar to the other taxa in this complex, was not included. Here we present a...
  9. Mitochondrial dysfunction and human immunodeficiency virus infection

    Mitochondrial dysfunction and human immunodeficiency virus infection

    Human immunodeficiency virus (HIV) infection and the pharmacological treatment thereof have both been shown to affect mitochondrial function in a number of tissues, and each may cause specific organ pathology through specific mitochondrial pathways. HIV has been shown to kill...
  10. Anaesthesia with dexmedetomidine and remifentanil in a child with mitochondrial myopathy

    Anaesthesia with dexmedetomidine and remifentanil in a child with mitochondrial myopathy

    Item type: Journal Article • Journal: Southern African Journal of Anaesthesia and Analgesia
    Patients with mitochondrial disorders have complex physiological issues which create a challenging scenario with regard to the safe provision of anaesthetic care. Within the spectrum of mitochondrial disorders, patients can be susceptible to multiple adverse effects and drug reactions from...
