  1. Effect of nitrogen application, seeding rate and defoliation height on mixtures of <em>Trifolium vesiculosum</em> cv Amclo and <em>Lolium multiflorum</em> cv Midmar: I. dry matter production, crude protein content and crude protein production*

    Item type: Journal Article • Journal: Journal of the Grassland Society of Southern Africa
    The interaction between Trifolium vesiculosum cv Amclo and Lolium multiflorum cv Midmar was measured in a field trial, in terms of dry matter production, crude protein content and crude protein production. The treatments included in the field trials were five...
  2. Effect of nitrogen application, seeding rate and defoliation height on mixtures of <em>Trifolium vesiculosum</em> cv Amclo and <em>Lolium Multiflorum</em> cv midmar: II. Yield advantage as reflected in the land equivalent ratio*

    Item type: Journal Article • Journal: Journal of the Grassland Society of Southern Africa
    Pure stands of Trifolium vesiculosum cv Amclo and Lolium multiflorum cv Midmar were compared with a range of mixtures of these two species in terms of dry matter production, crude protein content and crude protein production. Land equivalent ratios (LER)...

    Item type: Journal Article • Journal: Journal of the Grassland Society of Southern Africa
    The interaction between Trifolium subterraneum cv Mt Barker and Lolium multiflorum cv Midmar was measured in a field trial in terms of dry matter production, crude protein content and crude protein production. The treatments included five different seeding rates of...
  4. Determining sample size for assessing species composition in grassland<sup>1</sup>

    Item type: Journal Article • Journal: Journal of the Grassland Society of Southern Africa
    Species composition is measured in grasslands for a variety of reasons. Commonly, observations are made using the wheel‐point apparatus. However, the problem of determining optimum sample size has not yet been satisfactorily resolved. In this study the wheel‐point apparatus was...
  5. COMPOSITION, ABUNDANCE AND SEASONALITY OF LARVAL FISH IN RICHARDS BAY HARBOUR, KWAZULU-NATAL, SOUTH AFRICA

    COMPOSITION, ABUNDANCE AND SEASONALITY OF LARVAL FISH IN RICHARDS BAY HARBOUR, KWAZULU-NATAL, SOUTH AFRICA

    Item type: Journal Article • Journal: Southern African Journal of Aquatic Sciences
    The present study examined the composition, abundance and seasonality of fish larvae occurring in Richards Bay Harbour, over an 18-month period from June 1991 to November 1992. Ichthyoplankton samples were collected every six weeks at top, mid and bottom depths...
  6. Bottlenose dolphin <em>Tursiops truncatus</em> at São Tomé Island (São Tomé and Príncipe) — relative abundance, site fidelity and social structure

    Bottlenose dolphin <em>Tursiops truncatus</em> at São Tomé Island (São Tomé and Príncipe) — relative abundance, site fidelity and social structure

    Item type: Journal Article • Journal: African Journal of Marine Science
    Although the bottlenose dolphin Tursiops truncatus is one of the most common cetacean species around São Tomé Island, Gulf of Guinea, little research has focused on this species in this region. This study investigated the population of bottlenose dolphins around...
  7. Distribution, behaviour and photo-identification of Atlantic humpback dolphins <em>Sousa teuszii</em> off Flamingos, Angola

    Distribution, behaviour and photo-identification of Atlantic humpback dolphins <em>Sousa teuszii</em> off Flamingos, Angola

    Item type: Journal Article • Journal: African Journal of Marine Science
    Atlantic humpback dolphins Sousa teuszii are a priority for research due to their restricted geographic range, narrow ecological niche and the paucity of existing information. The distribution and behaviour of S. teuszii off Flamingos, southern Angola, was investigated during summer...
