  1. Calculating stocking rates for game ranches: Substitution ratios for use in the Mopani Veld

    Calculating stocking rates for game ranches: Substitution ratios for use in the Mopani Veld

    Item type: Journal Article • Journal: African Journal of Range & Forage Science
    Determination of carrying capacity for mixed‐ or multi‐species grazing systems is complex. Commonly, each species is compared to the standard large stock unit (LSU) used in conventional agriculture. However, this approach does not allow for ecological separation, and thus overlooks...
  2. Diversity and structure of woody vegetation across areas with different soils in Gonarezhou National Park, Zimbabwe

    Diversity and structure of woody vegetation across areas with different soils in Gonarezhou National Park, Zimbabwe

    Item type: Journal Article • Journal: Southern Forests: a Journal of Forest Science
    Despite the importance of edaphic factors in influencing woody vegetation diversity and structure in savannas, there is still limited research on the topic across most savanna ecosystems. Here we investigate the differences and/or similarities of woody vegetation diversity and structure...
  3. A comparison of four different standards of reference for the animal unit for Determining stocking rate

    Item type: Journal Article • Journal: Journal of the Grassland Society of Southern Africa
    No single standard of reference for the animal unit (AU) for determining stocking rates has materialized. Often, therefore, it is not clear which standard of reference for the AU or which method of determining stocking rate has been used in...
  4. Veld condition and animal performance: Application of an optimal foraging model

    Item type: Journal Article • Journal: Journal of the Grassland Society of Southern Africa
    An optimal foraging model was used to predict food ingestion rate, food digestion rate and animal energy gains relative to requirements as functions of dietary composition. Energy gains were maximized by ranking food types in order of their effective value,...
  5. Comparative patterns of sodium accumulation in leaves of selected savanna species growing on sodic and nonsodic soils

    Comparative patterns of sodium accumulation in leaves of selected savanna species growing on sodic and nonsodic soils

    Item type: Journal Article • Journal: South African Journal of Plant and Soil
    Plants show differing mechanisms of tolerance to high sodium levels in soils. Physiological and biochemical mechanisms have been investigated for many crop species but little information is available for indigenous tree and grass species. Foliar concentrations of sodium, calcium, potassium,...
  6. Seasonal botanical and chemical composition of sheep and goat diets on a common range in eastern Africa

    Seasonal botanical and chemical composition of sheep and goat diets on a common range in eastern Africa

    Item type: Journal Article • Journal: African Journal of Range & Forage Science
    The botanical and chemical composition, intake and digestibility of local sheep (Ovis aries) and goat (Capra hirtus) diets were evaluated over the wet (growing) and dry (dormant) seasons. Diet botanical composition was related to the vegetation composition on the range...
  7. Aspects of the biology and fisheries of an economically important sparid <em>Dentex macrophthalmus</em> (Bloch 1791) in the Namibe province, Angola

    Aspects of the biology and fisheries of an economically important sparid <em>Dentex macrophthalmus</em> (Bloch 1791) in the Namibe province, Angola

    Item type: Journal Article • Journal: African Journal of Marine Science
    The sparid Dentex macrophthalmus is a widespread, important fishery species along most of the West African coast from southern Namibia to the Mediterranean. In southern Angola it is an important artisanal species targeted predominantly by handline fishers. A biological and...
  8. St Helena Bay (southern Benguela) then and now: muted climate signals, large human impact

    St Helena Bay (southern Benguela) then and now: muted climate signals, large human impact

    Item type: Journal Article • Journal: African Journal of Marine Science
    The development of suitable reference states for ecosystem-based management requires documentation of changes in structure and functioning of marine ecosystems, including assessment of the relative importance of bottom-up and top-down processes as drivers of change. We used monitoring data available...
  9. Large loop excision of the transformation zone (LLETZ): a pathology evaluation in the Limpopo province, South Africa

    Large loop excision of the transformation zone (LLETZ): a pathology evaluation in the Limpopo province, South Africa

    Item type: Journal Article • Journal: Southern African Journal of Gynaecological Oncology
    Objective: To evaluate the cytological and histopathological concordance in large loop excision of the transformation zone (LLETZ) specimens, and the outcomes according to the characteristics of the excision margins.
