  1. Marine reserve effects on population density and size structure of commonly and rarely exploited limpets in South Africa

    Marine reserve effects on population density and size structure of commonly and rarely exploited limpets in South Africa

    Item type: Journal Article • Journal: African Journal of Marine Science
    Marine reserves are commonly used to conserve living resources, but their effectiveness where policing is difficult is unclear. We compared monthly population density and size structure data collected over 20 months for two rarely and two commonly exploited intertidal limpets...
  2. Effects of marine reserves on the reproductive biology and recruitment rates of commonly and rarely exploited limpets

    Effects of marine reserves on the reproductive biology and recruitment rates of commonly and rarely exploited limpets

    Item type: Journal Article • Journal: African Journal of Marine Science
    We tested the effects of marine reserve status on the reproductive biology and recruitment rates of two commonly exploited (Helcion concolor, Scutellastra longicosta) and two rarely exploited (Cellana capensis, Scutellastra granularis) limpet species using two reserve and two non-reserve sites...
  3. The impact of river flooding and high flow on the demersal fish assemblages of the freshwater-dominated Great Fish Estuary, South Africa

    The impact of river flooding and high flow on the demersal fish assemblages of the freshwater-dominated Great Fish Estuary, South Africa

    Item type: Journal Article • Journal: African Journal of Marine Science
    Freshwater inflow has a strong impact on the biological, chemical and physical characteristics of estuaries, which in turn affect the distribution and abundance of estuarine organisms. Increased climatic variability associated with climate change is predicated to modify precipitation patterns, which...
