  1. Seasonal pattern of chytridiomycosis in common river frog (<em>Amietia angolensis</em> ) tadpoles in the South African Grassland Biome

    Seasonal pattern of chytridiomycosis in common river frog (<em>Amietia angolensis</em> ) tadpoles in the South African Grassland Biome

    Item type: Journal Article • Journal: African Zoology
    Environmental parameters such as temperature and rainfall influence the biology of amphibians and are likely to similarly influence the growth and prevalence of associated pathogens. Amphibian chytrid fungus, Batrachochytrium dendrobatidis (Bd), causes an infectious disease, chytridiomycosis, in amphibians worldwide. Field...
  2. Resolving the confusion: <em>Amietia vertebralis</em> and <em>A. umbraculata</em> tadpole morphology

    Resolving the confusion: <em>Amietia vertebralis</em> and <em>A. umbraculata</em> tadpole morphology

    Item type: Journal Article • Journal: African Zoology
    Morphological similarities between the tadpoles of Amietia umbraculata and A. vertebralis have led to confusion and incorrect descriptions and identifications in the literature. Based on 33 body measurements and ratios we revised the morphological descriptions of the tadpoles of the...
  3. A Method for Monitoring Egg Production by the <em>Eucalyptus</em> Borers <em>Phoracantha</em> spp. (Cerambycidae)

    Item type: Journal Article • Journal: South African Forestry Journal
    This sampling method for monitoring P. semipunctata egg production in the forest involves attaching four strips of shed Eucalyptus bark (each 40 × 80 mm) by means of drawing pins to a freshly felled Eucalyptus log. The highest number of...
  4. Preliminary results on species selection by animals on sour grassveld

    Preliminary results on species selection by animals on sour grassveld

    A study of species selection by cattle under a system of controlled selective grazing using wheel‐point surveys and fistulated animals has demonstrated that both techniques provide valuable information on the preference shown for such species as Andropogon amplectens, Eulalia villosa,...
  5. Veld composition in relation to grazing capacity <em>die verhouding tussen veld samestelling en weidingskapasiteit</em>

    Item type: Journal Article • Journal: Journal of the Grassland Society of Southern Africa
    Present methods of evaluating veld composition in relation to grazing capacity can be criticised on grounds of subjectivity, especially with regard to the assignment of relative values to the constituent species. Data relating to botanical composition and estimated grazing capacity,...
  6. Droë massaproduksie van vyf eenjarige <em>Medicago</em>‐genotipes in die sentrale oranje‐vrystaat, soos beinvloed deur planttyd

    Item type: Journal Article • Journal: Journal of the Grassland Society of Southern Africa
    Bogrondse droë massa‐opbrengste (DM) van Medicago truncatula, cvv. Cyprus en Jemalong, M. aculeata var. inermis, cv. SA 4438, M. orbicularis, cv. SA 2552 en M. rugosa, cv. Paragosa wat op ses verskillende datums gevestig is, is in ‘n veldproef onder...
  7. ‘n Studie van ruproteïeninhoud en verteerbaarheid van vyf eenjarige <em>medica</em>go‐genotipes in die sentrale oranje‐vrystaat

    Item type: Journal Article • Journal: Journal of the Grassland Society of Southern Africa
    Die bogrondse groei van Medicago truncatula, cvv. Cyprus en Jemalong, M. aculeata var. inermis, cv. SA 4438, M. orbicularis, pv. SA 2552 en M. rugosa, cv. Paragosa, afkomstig van ‘n besproeide veldproef, is vir ruproteïen en vir in vitro‐ verteerbaarheid...
  8. A study of variations in floristic composition of highveld in the eastern Transvaal

    Item type: Journal Article • Journal: Journal of the Grassland Society of Southern Africa
    Floristic surveys of two 1500m line transects in veld provided data which indicated the nature of variations in veld composition, expressed in terms of species, palatability classes or weighted palatability classes. The transects were subjectively subdivided into units comprising relatively...
