  1. Use of particle-size data to predict potential pelagic-fish yields of some southern African areas

    Use of particle-size data to predict potential pelagic-fish yields of some southern African areas

    Item type: Journal Article • Journal: South African Journal of Marine Science
    A particle-size spectrum model is used to estimate standing stocks of some pelagic fish from measurements of phytoplankton chlorophyll in two exploited regions in southern Africa (southern Benguela and off South West Africa/Namibia) and in two unexploited regions (the Agulhas...
  2. Simulation studies of trophic flows and nutrient cycles in Benguela upwelling foodwebs

    Simulation studies of trophic flows and nutrient cycles in Benguela upwelling foodwebs

    Item type: Journal Article • Journal: South African Journal of Marine Science
    The traditional model of short, efficient food chains in upwelling regions is revised to incorporate microplanktonic processes and near-exclusive carnivory by anchovy. The new model is based on analyses of outputs of simulation models. These include a size-based micro/mesoplankton model...
  3. Microheterotrophic pathways in the southern Benguela upwelling system

    Microheterotrophic pathways in the southern Benguela upwelling system

    Item type: Journal Article • Journal: South African Journal of Marine Science
    During the 1980s, there was a major shift in the understanding of the structure of marine foodwebs. As a result, the microbial loop has been incorporated into the classical concept of the planktonic food chain. Heterotrophic bacteria and Protozoa have...
  4. BIOLOGY OF THE TRISTAN THRUSH <em>NESOCICHLA EREMITA</em>

    BIOLOGY OF THE TRISTAN THRUSH <em>NESOCICHLA EREMITA</em>

    Item type: Journal Article • Journal: Ostrich: Journal of African Ornithology
    M.W. Fraser, P.G. Ryan, W.R.J. Dean, D.J. Briggs, & C.L. Moloney 1994. The biology of the Tristan Thrush Nesocichla eremita. Ostrich 65:14-25.
  5. Comparing trophic flows in the southern Benguela to those in other upwelling ecosystems

    Comparing trophic flows in the southern Benguela to those in other upwelling ecosystems

    Item type: Journal Article • Journal: South African Journal of Marine Science
    A balanced trophic flow model of the southern Benguela ecosystem is presented, averaging the period 1980–1989 and emphasizing upper trophic levels. The model is based largely on studies conducted within the framework of the Benguela Ecology Programme and updates the...
  6. PREY SELECTION AND TEMPORAL VARIATION IN THE DIET OF SUBANTARCTIC SKUAS AT INACCESSIBLE ISLAND, TRISTAN DA CUNHA

    PREY SELECTION AND TEMPORAL VARIATION IN THE DIET OF SUBANTARCTIC SKUAS AT INACCESSIBLE ISLAND, TRISTAN DA CUNHA

    Item type: Journal Article • Journal: Ostrich: Journal of African Ornithology
    Ryan, P.G., & Moloney, C.L. 1991. Prey selection and temporal variation in the diet of Subantarctic Skuas at Inaccessible Island, Tristan da Cunha. Ostrich 62:52-58.
  7. Ecosystem approach to fisheries management in the southern Benguela: a workshop overview

    Ecosystem approach to fisheries management in the southern Benguela: a workshop overview

    Item type: Journal Article • Journal: African Journal of Marine Science
    A workshop was held in Cape Town in December 2002 to introduce the concept of an ecosystem approach to fisheries (EAF) management in the southern Benguela, and to examine the options for implementing an EAF in South Africa. The workshop...
  8. Contributions of the Benguela ecology programme to pelagic fisheries management in South Africa

    Contributions of the Benguela ecology programme to pelagic fisheries management in South Africa

    Item type: Journal Article • Journal: African Journal of Marine Science
    In 1982, the Benguela Ecology Programme (BEP) created a formal, multi-institutional research partnership in South Africa. During the next two decades, the BEP directed many aspects of pelagic ecosystem research in the southern Benguela upwelling region, aiming to improve fisheries...
  9. An ecosystem framework for fisheries management in the southern Benguela upwelling system

    An ecosystem framework for fisheries management in the southern Benguela upwelling system

    Item type: Journal Article • Journal: African Journal of Marine Science
    A "four-step framework" for applying ecosystem approaches to fisheries management in the southern Benguela is proposed. First, static ecosystem models can be used to highlight important interactions by assessing the net trophic impacts of each species on all the others...
