    Kill your enemies and eat them with the help of your toxins: an algal strategy

    Item type: Journal Article • Journal: African Journal of Marine Science
    Prymnesium spp. have been shown to kill both their grazers and other algal species, by producing allelopathic compounds. Killing nutrient-competing phytoplankton species enables Prymnesium to freely utilise limiting resources. Mixotrophy, i.e. the ability to ingest bacteria, other algae, and potential...
  2. Water location, piospheres and a review of evolution in African ruminants

    Water location, piospheres and a review of evolution in African ruminants

    Item type: Journal Article • Journal: African Journal of Range & Forage Science
    The main radiation of large mammalian herbivores in Africa took place in the Pliocene–Pleistocene, when a long-term trend towards aridification promoted grasslands and the diversification of ruminant grazers. Traditional models of this evolution identify habitat fragmentation in response to climate...
  3. Kelp forests in False Bay: urchins vs macroalgae in South Africa’s southwest coast biogeographical transition zone

    Kelp forests in False Bay: urchins vs macroalgae in South Africa’s southwest coast biogeographical transition zone

    Item type: Journal Article • Journal: African Journal of Marine Science
    Kelp forests along South Africa's southwest coast occur in a region of biogeographical overlap. Commonly referred to as transition-zone kelp forests, these dynamic ecosystems are particularly susceptible to grazing from species such as urchins. This study explores relationships between urchins...
