  1. Abundance estimates of an isolated population of common bottlenose dolphins <em>Tursiops truncatus</em> in Walvis Bay, Namibia, 2008–2012

    Abundance estimates of an isolated population of common bottlenose dolphins <em>Tursiops truncatus</em> in Walvis Bay, Namibia, 2008–2012

    Item type: Journal Article • Journal: African Journal of Marine Science
    The coastal population of common bottlenose dolphins Tursiops truncatus found in Namibia is regionally isolated and unique. This population faces several potential anthropogenic threats, especially in Walvis Bay, including boat-based tourism, a commercial harbour undergoing expansion, and aquaculture for oysters...
  2. Spatial pattern and variability of soil and hillslope properties in a granitic landscape 1. Pretoriuskop area

    Spatial pattern and variability of soil and hillslope properties in a granitic landscape 1. Pretoriuskop area

    Item type: Journal Article • Journal: South African Journal of Plant and Soil
    Characteristics of nine hillslope profiles and selected properties of 69 soil profiles were determined in order to evaluate the spatial pattern and variability of soil and hillslope properties in a granitic area near Pretoriuskop, Kruger National Park. A transect design...
  3. Spatial pattern and variability of soil and hillslope properties in a granitic landscape 2. Pretoria—Johannesburg area

    Spatial pattern and variability of soil and hillslope properties in a granitic landscape 2. Pretoria—Johannesburg area

    Item type: Journal Article • Journal: South African Journal of Plant and Soil
    Using a transect design, a detailed examination was made of nine hillslopes and 64 soil profiles in the granitic area between Johannesburg and Pretoria to assess the spatial pattern and variability of soil and hillslope properties. The land surface was...
  4. The IFR process: beyond the specialist workshop

    The IFR process: beyond the specialist workshop

    Item type: Journal Article • Journal: African Journal of Aquatic Science
    The process of determining Instream Flow Requirements (IFRs) has been well developed to the point at which an IFR table which quantifies the temporal distribution of discharge, upon which the modified flow regime is based, is produced. During the last...
  5. Chameleons on the move: survival and movement of the Cape dwarf chameleon, <em>Bradypodion pumilum,</em> within a fragmented urban habitat

    Chameleons on the move: survival and movement of the Cape dwarf chameleon, <em>Bradypodion pumilum,</em> within a fragmented urban habitat

    Item type: Journal Article • Journal: African Zoology
    Reptiles have an amazing diversity of life-history attributes ranging from the shortest- to longest-lived of vertebrate species. Estimating survival in wild populations is of key importance when understanding population dynamics and life-history evolution. However, data are lacking for a large...
  6. Ergonomic Research in South African Forestry

    Item type: Journal Article • Journal: South African Forestry Journal
    After a short reflection on the South African forest industry the article discusses various research projects in ergonomics.
  7. A model for predicting long term economic optimum stocking rates for beef cattle grazing dryland pastures

    Item type: Journal Article • Journal: Journal of the Grassland Society of Southern Africa
    Previous models relating profit to stocking rate have not taken into account annual variation in rainfall. A model is developed here to allow for this factor. The frequency distribution of annual rainfall is used to demonstrate how the stocking rate...
  8. Die wiskundige simulering van koolhidraattranslokasie in natuurlike grasveld<sup>1</sup>

    Item type: Journal Article • Journal: Journal of the Grassland Society of Southern Africa
    Die groeifunksies benodig vir die simulasie van produksie van ‘n Themeda triandra‐grasveld met behulp van die PUTU 11 simulasiemodel is ontwikkel. Vir die ontwikkeling van die model is die veldproduksiedata van die 1980/81 groeiseisoen gebruik waarna dit suksesvol, vir drie...
  9. Simulating browse production and response of <em>Acacia karroo</em> to defoliation I. Model description and sensitivity analyses

    Item type: Journal Article • Journal: Journal of the Grassland Society of Southern Africa
    The model is aimed at synthesizing existing data to enhance the understanding of this data and explore the consequences of possible browse management strategies. It gives a good reproduction of the shoot and leaf growth responses used to develop it...
  10. Simulating browse production and response of <em>Acacia karroo</em> to defoliation II. Evaluation of browse management systems and strategies

    Item type: Journal Article • Journal: Journal of the Grassland Society of Southern Africa
    To assess management implications, a model was used to simulate the response of Acacia karroo to a wide range of different climatic patterns and defoliation regimes. The model predicts that if poor growing conditions initiate growth later in spring than...
