  1. THE EFFECTS OF TROUT-FARM EFFLUENTS ON BENTHIC INVERTEBRATE COMMUNITY STRUCTURE IN RIVERS IN THE SOUTH-WESTERN CAPE, SOUTH AFRICA

    THE EFFECTS OF TROUT-FARM EFFLUENTS ON BENTHIC INVERTEBRATE COMMUNITY STRUCTURE IN RIVERS IN THE SOUTH-WESTERN CAPE, SOUTH AFRICA

    Item type: Journal Article • Journal: Southern African Journal of Aquatic Sciences
    The south-western Cape is currently responsible for 45% of the total annual trout production in South Africa and further expansion of this industry in the region is likely. A preliminary survey of seven trout farms situated on the upper reaches...
  2. STUDIES ON THE ZOOBENTHOS OF SOME SOUTHERN CAPE COASTAL LAKES. SPATIAL AND TEMPORAL CHANGES IN THE BENTHOS OF SWARTVLEI, SOUTH AFRICA, IN RELATION TO CHANGES IN THE SUBMERGED LITTORAL MACROPHYTE COMMUNITY

    STUDIES ON THE ZOOBENTHOS OF SOME SOUTHERN CAPE COASTAL LAKES. SPATIAL AND TEMPORAL CHANGES IN THE BENTHOS OF SWARTVLEI, SOUTH AFRICA, IN RELATION TO CHANGES IN THE SUBMERGED LITTORAL MACROPHYTE COMMUNITY

    Item type: Journal Article • Journal: Journal of the Limnological Society of Southern Africa
    Major changes in the benthic macro-invertebrate community of the littoral zone of Swartvlei, South Africa, took place between January and April 1978, and the equivalent months of 1980. These changes, which were associated with a collapse of the submerged littoral...
  3. SALINITY, FLOODS AND THE INFAUNAL MACROBENTHIC COMMUNITY OF THE ST LUCIA ESTUARY, KWAZULU-NATAL, SOUTH AFRICA

    SALINITY, FLOODS AND THE INFAUNAL MACROBENTHIC COMMUNITY OF THE ST LUCIA ESTUARY, KWAZULU-NATAL, SOUTH AFRICA

    Item type: Journal Article • Journal: Southern African Journal of Aquatic Sciences
    The St Lucia estuary and lake comprise some 80 % of the estuarine area of KwaZulu-Natal. The system is subject to floods and hypersaline conditions, the latter twice exceeding 100 since 1970. The lake is connected to the sea by...
  4. Effects of fishing on a temperate reef community in South Africa 2: benthic invertebrates and algae

    Effects of fishing on a temperate reef community in South Africa 2: benthic invertebrates and algae

    Item type: Journal Article • Journal: African Journal of Marine Science
    The effect of fishing on benthic reef communities was studied by comparing reefs within and outside the Goukamma Marine Protected Area (MPA) on the South African warm-temperate south coast. Although study sites were similar in terms of bathymetry and oceanographic...
  5. Effects of plantation residue management on the community structure of wattle regeneration invertebrate pests in South Africa

    Effects of plantation residue management on the community structure of wattle regeneration invertebrate pests in South Africa

    Item type: Journal Article • Journal: Southern Forests: a Journal of Forest Science
    There is a limited availability of land for the expansion of South African black wattle plantations. One way to increase productivity is to ensure the survival of seedlings during regeneration, thereby increasing the stocking of compartments. Soil invertebrate pests constitute...
  6. Benthic macroinvertebrate assemblages in mangroves and open intertidal areas on the Dar es Salaam coast, Tanzania

    Benthic macroinvertebrate assemblages in mangroves and open intertidal areas on the Dar es Salaam coast, Tanzania

    Item type: Journal Article • Journal: African Journal of Aquatic Science
    The assemblages of benthic macroinvertebrates in mangroves and open intertidal areas of the Dar es Salaam coast, Tanzania, was investigated in 2013–2014, revealing 56 species. Higher density, species richness and diversity were recorded in open intertidal areas, compared to nearby...

    A brief overview of the ACEP project: Ecosystem Processes in the KwaZulu-Natal Bight<xref ref-type="fn" rid="FN0000"/>

    Item type: Journal Article • Journal: African Journal of Marine Science
    This introductory paper lays the basis for this supplementary issue by briefly presenting the state of knowledge on the KwaZulu-Natal (KZN) Bight at the start of this multi-disciplinary, multi-institutional, ship-based research project that ran from 2009 to 2013. The rationale...
  8. Zambian Invertebrate Scoring System (ZISS): A macroinvertebrate-based biotic index for rapid bioassessment of southern tropical African river systems

    Zambian Invertebrate Scoring System (ZISS): A macroinvertebrate-based biotic index for rapid bioassessment of southern tropical African river systems

    Item type: Journal Article • Journal: African Journal of Aquatic Science
    An extensive survey of tropical rivers, conducted during 2009–2012 throughout Zambia, collected 151 samples of benthic macroinvertebrates, located on 95 rivers in six of the nine freshwater ecoregions. Associated data for physico-chemistry, human activities and ecosystem stressors were collected. Data...
  9. THE INVERTEBRATE FAUNA AND BIOTIC INDEX VALUE OF WATER QUALITY OF THE GREAT BERG RIVER, WESTERN CAPE

    THE INVERTEBRATE FAUNA AND BIOTIC INDEX VALUE OF WATER QUALITY OF THE GREAT BERG RIVER, WESTERN CAPE

    Item type: Journal Article • Journal: Journal of the Limnological Society of Southern Africa
    The invertebrate fauna was sampled at seven localities in the main stream of the Berg River in 1974. These results are discussed and compared with those of Harrison and Elsworth (1958). The results obtained were also used in applying the...
  10. Microbial community function and structure on coal mine discard under rehabilitation

    Microbial community function and structure on coal mine discard under rehabilitation

    Item type: Journal Article • Journal: South African Journal of Plant and Soil
    The rehabilitation of coal mine discard is problematic, especially since the lack of measures to evaluate the success of rehabilitation in terms of the self-sustainability of soil ecosystems established on these sites. In this study, the potential for using microbial...
