  1. Diet and time-activity budget of White-backed Mousebirds <em>Colius colius</em> in south-western South Africa

    Diet and time-activity budget of White-backed Mousebirds <em>Colius colius</em> in south-western South Africa

    Item type: Journal Article • Journal: Ostrich: Journal of African Ornithology
    Mousebirds (Coliiformes) are unusual in having an exclusively vegetarian diet that includes substantial foliage and by using huddling and sunning to assist thermoregulation. Although previous studies have identified plant species and plant parts consumed by mousebirds, the relative importance of...
  2. Biology of <em>Cicadulina</em> leafhoppers and epidemiology of maize streak virus disease in West Africa

    Biology of <em>Cicadulina</em> leafhoppers and epidemiology of maize streak virus disease in West Africa

    Item type: Journal Article • Journal: South African Journal of Plant and Soil
    Studies have been conducted in Nigeria on biology of Cicadulina leafhopper vectors of maize streak virus (MSV), the role of indigenous grasses as reservoirs of virus and vectors, and on incidence and severity of MSV in relation to maize varietal...
  3. Historical overview of breeding for durable resistance to maize streak virus for tropical Africa

    Historical overview of breeding for durable resistance to maize streak virus for tropical Africa

    Item type: Journal Article • Journal: South African Journal of Plant and Soil
    Maize streak virus (MSV) was first studied by Storey in Kenya in the 1920s and resistance transferred into East African maize in the 1960's. Yet the majority of farmers of East Africa are still growing streak-susceptible maize. At the International...
  4. Normative reasons and the possibility of motivation

    Normative reasons and the possibility of motivation

    Item type: Journal Article • Journal: South African Journal of Philosophy
    This article defends a claim about the conditions under which agents possess normative reasons for action. According to this claim, an agent has a normative reason to ϕ only if it's psychologically possible for that reason to motivate the agent...
  5. FLUIDIFICATION OF QUIVERS AND THE TIETZE EXTENSION THEOREM FOR DIAGRAMS OF TOPOLOGICAL SPACES

    FLUIDIFICATION OF QUIVERS AND THE TIETZE EXTENSION THEOREM FOR DIAGRAMS OF TOPOLOGICAL SPACES

    Item type: Journal Article • Journal: Quaestiones Mathematicae
    For quivers with no directed cycles, the concept of fluidification is defined and used to prove that, under corresponding assumptions, the Tietze extension theorem for diagrams of topological spaces modeled on such quivers holds. Another application of the given concept...
  6. Fecundity and sexual maturity of the crab <em>Macrophthalmus depressus</em> (Brachyura: Ocypodidae) from Inhaca Island, Mozambique

    Fecundity and sexual maturity of the crab <em>Macrophthalmus depressus</em> (Brachyura: Ocypodidae) from Inhaca Island, Mozambique

    Item type: Journal Article • Journal: African Journal of Aquatic Science
    Some reproductive aspects of the ocypodid crab Macrophthalmus depressus, were investigated, with emphasis on fecundity and sexual maturity. Random intertidal crab samples taken in October 2002 were identified, sexed, measured, checked for the presence of eggs on female pleopods, dissected...
  7. Are mist-nets suitable for rapid habitat evaluations in the tropics? Results from a study in Guinea-Bissau

    Are mist-nets suitable for rapid habitat evaluations in the tropics? Results from a study in Guinea-Bissau

    Item type: Journal Article • Journal: Ostrich: Journal of African Ornithology
    Catry, P., Araújo, A., Cruz, C., Pinheiro, A., Poças, M., Nadum, J., Armelin, M.& Pereira, J.R. 1999. Are mist-nets suitable for rapid habitat evaluations in the tropics? Results from a study in Guyinea-Bissau. Ostrich 70(2) 134–137
  8. Probable population decline of the Little Bustard <em>Tetrax tetrax</em> in north-west Africa

    Probable population decline of the Little Bustard <em>Tetrax tetrax</em> in north-west Africa

    Item type: Journal Article • Journal: Ostrich: Journal of African Ornithology
    To document the population trend of the Little Bustard in north-west Africa, we performed an extensive literature review, and conducted six surveys in seven areas with potentially suitable habitat in north-western Morocco between 1999 and 2005. Both the number of...
  9. DNA sequences from the Little Brown Bustard <em>Eupodotis humilis</em> suggest its close phylogenetic relationship to the Little Bustard <em>Tetrax tetrax</em>

    DNA sequences from the Little Brown Bustard <em>Eupodotis humilis</em> suggest its close phylogenetic relationship to the Little Bustard <em>Tetrax tetrax</em>

    Item type: Journal Article • Journal: Ostrich: Journal of African Ornithology
    Taxonomic classification of birds based exclusively on morphology and plumage traits has often been found to be inconsistent with true evolutionary history when tested with molecular phylogenies based on neutrally evolving markers. Here we present cytochrome-b gene sequences for the...
