  1. Phylogeography of oribi antelope in South Africa: evolutionary versus anthropogenic panmixia

    Phylogeography of oribi antelope in South Africa: evolutionary versus anthropogenic panmixia

    Item type: Journal Article • Journal: African Zoology
    The increased rate of human-driven change is a major threat to biodiversity. Although there is sufficient evidence to suggest that species notably alter their ranges, facilitation of such movement for larger vertebrate species often places burdens on management agencies. Oribi...
  2. Cryptic diversity in the common flap-necked chameleon <em>Chamaeleo dilepis</em> in South Africa

    Cryptic diversity in the common flap-necked chameleon <em>Chamaeleo dilepis</em> in South Africa

    Item type: Journal Article • Journal: African Zoology
    The spatial genetic structure of a species, and whether distinct genetic lineages are present, is strongly influenced by their biology and habitat requirements. Given habitat specificity and low vagility, many herpetofaunal species are reservoirs for high levels of cryptic diversity;...
  3. Dispersal

    Dispersal

    Item type: Journal Article • Journal: African Zoology
  4. Introduction to Conservation Genetics

    Introduction to Conservation Genetics

    Item type: Journal Article • Journal: African Zoology
  5. Spirit(ed) away: preventing foetal alcohol syndrome with motivational interviewing and cognitive behavioural therapy

    Spirit(ed) away: preventing foetal alcohol syndrome with motivational interviewing and cognitive behavioural therapy

    Item type: Journal Article • Journal: South African Family Practice
    Foetal alcohol syndrome (FAS) is a growing concern in South Africa. In the Western Cape, prevalence rates for FAS are the highest in the world. Not surprisingly, the Western Cape also has some of the highest levels of alcohol consumption...
  6. Origin and putative colonization routes for invasive rodent taxa in the Democratic Republic of Congo

    Origin and putative colonization routes for invasive rodent taxa in the Democratic Republic of Congo

    Item type: Journal Article • Journal: African Zoology
    The threat posed by biological invasions is well established. An important consideration in preventing the spread of invasives and also subsequent introductions lies in understanding introduction pathways. The Democratic Republic of the Congo (DRC) houses a large percentage of the...
  7. The influence of gender roles and traditional healing on cervical screening adherence amongst women in a Cape Town peri-urban settlement

    The influence of gender roles and traditional healing on cervical screening adherence amongst women in a Cape Town peri-urban settlement

    Item type: Journal Article • Journal: South African Family Practice
    Background: Cervical cancer is the third most common gynaecologic malignancy worldwide and is the second most common cancer among South African women. Although entirely preventable, cervical cancer is responsible for the death of approximately 3 027, 53% of those diagnosed,...
  8. A comparison of genetic structure in two low-dispersal crabs from the Wild Coast, South Africa

    A comparison of genetic structure in two low-dispersal crabs from the Wild Coast, South Africa

    Item type: Journal Article • Journal: African Journal of Marine Science
    The Wild Coast in south-eastern South Africa is strongly influenced by the warm, southward-flowing Agulhas Current. This current has a significant impact on dispersal in the coastal biota of the region, and facilitates high levels of connectivity among populations. However,...
  9. The Magnesium and Glucose (MAG) Study: the prevalence and effect of hypomagnesaemia on diabetes control in a regional hospital in KwaZulu-Natal

    The Magnesium and Glucose (MAG) Study: the prevalence and effect of hypomagnesaemia on diabetes control in a regional hospital in KwaZulu-Natal

    Background: Diabetes mellitus (DM) poses a great burden of disease worldwide. The adverse effects of hypomagnesaemia (hypoMg2+) in patients with DM have been well described, with a higher prevalence of hypoMg2+ in patients with DM than in the general population...
  10. Effect of herbicides on survival of rhizobia and nodulation of peas, groundnuts and lucerne

    Effect of herbicides on survival of rhizobia and nodulation of peas, groundnuts and lucerne

    Item type: Journal Article • Journal: South African Journal of Plant and Soil
    Thirteen herbicides were tested for toxicity against strains of Rhizobium used in South African legume inoculants for lucerne, clover, soybeans, groundnuts and lupins, respectively. Each of alachlor, bromoxynil, proprop, metolachlor, naptalam + dinoseb, and trifluralin inhibited at least two of...
