  1. RELATIVELY NEGATIVE δ<sup>13</sup>C RATIOS OF MESOZOOPLANKTON IN THE SUNDAYS RIVER ESTUARY, COMMENTS ON POTENTIAL CARBON SOURCES

    RELATIVELY NEGATIVE δ13C RATIOS OF MESOZOOPLANKTON IN THE SUNDAYS RIVER ESTUARY, COMMENTS ON POTENTIAL CARBON SOURCES

    Item type: Journal Article • Journal: Southern African Journal of Aquatic Sciences • Authors: H.L. Jerling --- Department of Zoology, South Africa T.H. Wooldridge --- Department of Zoology, South Africa
    Mesozooplankton, submergent and fringing macrophytes and particles suspended in the water column in the Sundays River estuary South Africa were analyzed for δ13C isotope ratios. Highly negative values (−28.3‰ to −32.0‰) for the mesozooplankton species suggest the possibility of phytoplankton...

  2. Characterisation of the mesozooplankton community in response to contrasting estuarine salinity gradients in the Eastern Cape, South Africa

    Characterisation of the mesozooplankton community in response to contrasting estuarine salinity gradients in the Eastern Cape, South Africa

    Item type: Journal Article • Journal: African Journal of Aquatic Science • Authors: TH Wooldridge --- Department of Zoology, South Africa
    Structure and pattern of mesozooplankton in three tidal estuaries experiencing contrasting salinity gradients were investigated. In the Kariega Estuary, where freshwater inflow was persistently low with little variation in flow, salinity values exceeded 28–30 for long periods (years) throughout the...
