  1. Predatory pelagic fishes of the Bijagós Archipelago (Guinea-Bissau) show high overlap in diets dominated by sardinella

    Predatory pelagic fishes of the Bijagós Archipelago (Guinea-Bissau) show high overlap in diets dominated by sardinella

    Item type: Journal Article • Journal: African Journal of Marine Science
    Knowledge of trophic interactions between the key components of marine communities is required to understand food-web dynamics and develop ecosystem-based management approaches. In West Africa, where fisheries sustain the livelihoods of a significant part of the human population, this understanding...
  2. Effects of aqueous extracts from <em>Artemisia afra</em> parts and soil on seed germination and early seedling development in selected plant species

    Effects of aqueous extracts from <em>Artemisia afra</em> parts and soil on seed germination and early seedling development in selected plant species

    Item type: Journal Article • Journal: South African Journal of Plant and Soil
    Aqueous extracts from leaves, stems, roots of the aromatic shrub Artemisia afra and soil on which Artemisia was grown, were used to investigate their inhibitory effects on germination and seedling development of maize (Zea mays), bean (Phaseolus vulgaris) and ryegrass...
  3. Soil properties as influenced by cultivation of the aromatic shrub <em>Artemisia afra</em>

    Soil properties as influenced by cultivation of the aromatic shrub <em>Artemisia afra</em>

    Item type: Journal Article • Journal: South African Journal of Plant and Soil
    The herbaceous aromatic shrub African wormwood (Artemisia afra) is thought to be indigenous to the Eastern Cape region of South Africa. In the natural environment, wherever the plant grows, patches of hard, bare ground develop around the plant. To investigate...
  4. Effects <em>of Artemisia afra</em> leaf extracts on seed germination of selected crop and weed species

    Effects <em>of Artemisia afra</em> leaf extracts on seed germination of selected crop and weed species

    Item type: Journal Article • Journal: South African Journal of Plant and Soil
    Herbicide resistance in weeds is a phenomenon threatening sustainable cereal production in the winter rainfall region of South Africa. Every possible weed control measure that may be used to complement chemical weed control measures should be investigated. The effect of...
  5. Predicting the extent of succulent thicket under current and future climate scenarios

    Predicting the extent of succulent thicket under current and future climate scenarios

    Item type: Journal Article • Journal: African Journal of Range & Forage Science
    Using data from the distribution records of the facultative CAM succulent shrub Portulacaria afra, and high resolution climate response surfaces, we developed a spatially explicit model of the potential distribution of the species in the Thicket Biome of the eastern...
  6. Ciguatera: the detection of neurotoxins in carnivorous reef fish from the coast of Cameroon, West Africa

    Ciguatera: the detection of neurotoxins in carnivorous reef fish from the coast of Cameroon, West Africa

    Item type: Journal Article • Journal: African Journal of Marine Science
    This work examined 64 large, carnivorous reef fish from the coastal waters of Cameroon for toxicity commonly associated with an incidence of ciguatera fish poisoning. The samples were also subjected to m-DNA analyses to confirm their taxonomic identification. The analyses...
