  1. ZOOPLANKTON DISTRIBUTION IN RELATION TO ENVIRONMENTAL CONDITIONS IN THE SWARTVLEI SYSTEM, SOUTHERN CAPE

    ZOOPLANKTON DISTRIBUTION IN RELATION TO ENVIRONMENTAL CONDITIONS IN THE SWARTVLEI SYSTEM, SOUTHERN CAPE

    Item type: Journal Article • Journal: Journal of the Limnological Society of Southern Africa
    Swartvlei is an ectogenic meromictic coastal lake connected to the sea via an estuary which closes periodically due to the formation of a sand bar across its mouth. The inflow of high-salinity water water from the sea into the lake...
  2. DECOMPOSITION IN ESTUARINE ECOSYSTEMS

    DECOMPOSITION IN ESTUARINE ECOSYSTEMS

    Item type: Journal Article • Journal: Journal of the Limnological Society of Southern Africa
    The varied sources of estuarine plant detritus and the processes and organisms involved in its decomposition are discussed in this review. In the case of emergent and peripheral vegetation, microbial decomposition commences in the phylloplane, with fairly rapid leaching of...

    Cross-shelf observations of diet and diel feeding behaviour of the bearded goby <em>Sufflogobius bibarbatus</em> off Namibia

    Item type: Journal Article • Journal: African Journal of Marine Science
    The diet of the bearded goby Sufflogobius bibarbatus was studied at two 48 h stations off the Namibian coast. The inner station (120 m) was characterised by a deep layer of low-oxygen bottom water (<0.5 ml DO l−1 or <10%...
  4. Bald kelp: natural and harvesting-induced frond loss in the South African kelp <em>Ecklonia maxima</em>

    Bald kelp: natural and harvesting-induced frond loss in the South African kelp <em>Ecklonia maxima</em>

    Item type: Journal Article • Journal: African Journal of Marine Science
    Ecklonia maxima dominates kelp beds on the west coast of southern Africa, and is commercially and ecologically valuable. Some plants lose all their secondary blades (fronds), leaving only the gas-filled bulb and short primary blade at the top of the...
