  1. Incidence of Natural Ectomycorrhizal Infection of Pine and Eucalypt Seedlings in Three KwaZulu-Natal Nurseries

    Item type: Journal Article • Journal: South African Forestry Journal
    A survey of the incidence of natural ectomycorrhizal infection on selected species of pines and eucalypts was conducted in three commercial timber nurseries near Pietermaritzburg in 1990. A follow-up survey was conducted on one of the nurseries in 1995. The...
  2. EQUI-MORPHIC FAMILIES IN CATEGORIES

    EQUI-MORPHIC FAMILIES IN CATEGORIES

    Item type: Journal Article • Journal: Quaestiones Mathematicae
    Motivated by his previous work on proximally fine and on equi-p-fine uniform spaces, the author extends some results about equi-uniformly continuous families of functions to the general setting of equi-morphic families in a category.
  3. WELL-COVERED GRAPHS: A SURVEY

    WELL-COVERED GRAPHS: A SURVEY

    Item type: Journal Article • Journal: Quaestiones Mathematicae
    A graph G is well-covered (or w-c) if every maximal independent set of points in G is also maximum. Clearly, this is equivalent to the property that the greedy algorithm for constructing a maximal independent set always results in a...
  4. DISCRETE UNIFORM STRUCTURES AND QUASITOPOI

    DISCRETE UNIFORM STRUCTURES AND QUASITOPOI

    Item type: Journal Article • Journal: Quaestiones Mathematicae
    It is known that no non-trivial subcategory of the category of topological spares is a quasitopos in the sense of Penon. The purpose of this note is to establish the existence of a proper class of sub-categories of the category...
  5. Trends in waterbird diversity at Banzi, Shokwe and Nyamithi pans, Ndumo Game Reserve, South Africa

    Trends in waterbird diversity at Banzi, Shokwe and Nyamithi pans, Ndumo Game Reserve, South Africa

    Item type: Journal Article • Journal: Ostrich: Journal of African Ornithology
    Our understanding of the timeous changes to pan-associated bird diversity is very important for the conservation of these wetlands. At Ndumo Game Reserve, a Ramsar site located in northern KwaZulu-Natal, seasonal (from March 2005 to January 2006 at Nyamithi Pan)...
  6. Origin of Bannerman's Turaco <em>Tauraco bannermani</em> in relation to historical climate change and the distribution of West African montane forests

    Origin of Bannerman's Turaco <em>Tauraco bannermani</em> in relation to historical climate change and the distribution of West African montane forests

    Item type: Journal Article • Journal: Ostrich: Journal of African Ornithology
    We determined the systematic relationships and approximate divergence time of Bannerman's Turaco Tauraco bannermani and used this information to test whether the origin and distribution of this species and its closest relatives are associated with the effects of historical climate...
  7. Phylogenetic relationships of African sunbird-like warblers: Moho (<em>Hypergerus atriceps</em>), Green Hylia (<

    Phylogenetic relationships of African sunbird-like warblers: Moho (<em>Hypergerus atriceps</em>), Green Hylia (<

    Item type: Journal Article • Journal: Ostrich: Journal of African Ornithology
    Pholidornis, Hylia and Hypergerus are monotypic songbird genera that share insectivorous feeding habits and a common habitat in West African forests. Each of these genera has some sunbird-like characters as well as other characters that suggest affinities to sylvioid warblers...
