  1. Conservation genetics of the vulnerable Treur River barb, <em>Barbus treurensis</em>

    Conservation genetics of the vulnerable Treur River barb, <em>Barbus treurensis</em>

    Item type: Journal Article • Journal: African Journal of Aquatic Science
    At present there are only two populations of the vulnerable Treur River barb, Barbus treurensis, in existence; a founder population in the upper Blyde River and a translocated population in the Treur River where the species became extinct. The translocated...
  2. Extreme levels of intra-specific divergence among Cape Peninsula populations of the Cape galaxias, <em>Galaxias zebratus</em> Castelnau 1861, reveals a possible species complex

    Extreme levels of intra-specific divergence among Cape Peninsula populations of the Cape galaxias, <em>Galaxias zebratus</em> Castelnau 1861, reveals a possible species complex

    Item type: Journal Article • Journal: African Journal of Aquatic Science
    The Cape galaxias, Galaxias zebratus, is part of the paleao-endemic fauna characteristic of the south-western Cape, South Africa, and is the only galaxiid found in continental Africa. A 284-bp fragment of the cytochrome b region of the mtDNA was sequenced...
  3. Observations of individual humpback whales utilising multiple migratory destinations in the south-western Indian Ocean

    Observations of individual humpback whales utilising multiple migratory destinations in the south-western Indian Ocean

    Item type: Journal Article • Journal: African Journal of Marine Science
    Movements of humpback whales Megaptera novaeangliae among breeding regions within the southwestern Indian Ocean are poorly understood. Understanding the relationships among breeding regions is critical for effective conservation and management strategies. Through systematic comparisons of molecular genotypes and both systematic...
  4. Molecular species identification and population genetics of chondrichthyans in South Africa: current challenges, priorities and progress

    Molecular species identification and population genetics of chondrichthyans in South Africa: current challenges, priorities and progress

    Item type: Journal Article • Journal: African Zoology
    Molecular genetic techniques, such as DNA barcoding and genotyping, are increasingly being used to assist with the conservation and management of chondrichthyans worldwide. Southern Africa is a shark biodiversity hotspot, with a large number of endemic species. According to the...
  5. Molecular research on the systematically challenging smoothhound shark genus <em>Mustelus</em>: a synthesis of the past 30 years

    Molecular research on the systematically challenging smoothhound shark genus <em>Mustelus</em>: a synthesis of the past 30 years

    Item type: Journal Article • Journal: African Journal of Marine Science
    The species-rich genus Mustelus (smoothhounds) of the shark family Triakidae is one of the most bio-economically important groups of elasmobranchs in the world’s oceans. Despite the commercial value of Mustelus, the systematics of the group remains largely unresolved and there...
  6. Indigenous High Forests in the Transvaal with Special Reference to Inventory and Monitoring Systems

    Item type: Journal Article • Journal: South African Forestry Journal
    The indigenous forests in the Transvaal comprise a total area of 35 385 ha, of which 18 088 ha or 51% are situated on State forest land. The forests are found mainly along the Drakensberg escarpment and, to a lesser...
  7. Conservation Developments in South African Forestry

    Item type: Journal Article • Journal: South African Forestry Journal
    The historical development of environmental conservational activities within the South African Forestry Industry is followed, and the changing emphasis from the conservation of the remaining indigenous forests (pre-1900) to water conservation, to natural assets and unplanted areas is highlighted. The...
  8. Habitat use by indigenous grazing ungulates in relation to sward structure and veld condition

    Item type: Journal Article • Journal: Journal of the Grassland Society of Southern Africa
    The objective of the study was to examine the relationships between the habitat requirements of different wild ungulate species, sward structure and veld condition. Veld condition score was correlated with sward height: habitats with high condition scores were dominated by...
  9. Development of a technique for assessing veld condition in the Kruger National Park using key grass species

    Item type: Journal Article • Journal: Journal of the Grassland Society of Southern Africa
    A technique based on key grass species was developed for assessing veld condition in the Kruger National Park in terms of its potential to produce grass forage for consumption by herbivores and fine fuels for veld burning. Fourteen grass species...
  10. Are multi‐paddock grazing systems economically justifiable?

    Item type: Journal Article • Journal: Journal of the Grassland Society of Southern Africa
    The financial implications of few‐ and multi‐paddock systems were modelled by a discounted cash flow analysis with the (discounted) present value as the dependent variable, and number of paddocks, farm run‐down time, time horizon and discount rate as the independent...
