  1. Transport and transformation of surface water masses across the Mascarene Plateau during the Northeast Monsoon season

    Transport and transformation of surface water masses across the Mascarene Plateau during the Northeast Monsoon season

    Item type: Journal Article • Journal: African Journal of Marine Science
    The Mascarene Plateau lies in the south-west Indian Ocean between the islands of Mauritius and the Seychelles Bank, and is characterised by a series of shallow banks separated by deep (>1 000 m), narrow channels. The plateau acts as an...
  2. The soil seed bank under nasella tussock infestations at Boschberg

    The soil seed bank under nasella tussock infestations at Boschberg

    Item type: Journal Article • Journal: South African Journal of Plant and Soil
    Nassella tussock (Stipa trichotoma Nees.) has a high annual production of seeds per plant. The total seed bank of all plants counted under a dense nassella infestation varied between 50 000 and 100 000 seeds m−2 surface area (5 cm...
  3. Investigations on the removal by animals of <em>Acacia longifolia</em> (Fabaceae) seed from the soil surface at Banhoek in the southwestern Cape

    Investigations on the removal by animals of <em>Acacia longifolia</em> (Fabaceae) seed from the soil surface at Banhoek in the southwestern Cape

    Item type: Journal Article • Journal: South African Journal of Plant and Soil
    Studies on the removal of Acacia longifolia (Andr.) Willd. seed from trays on the soil surface showed that 91,07% of the seed was removed after one week of exposure. Exclusion treatments indicated that ants removed 57,22% of the seed while...
  4. A field method to determine three dimensional infiltrability of vineyard soils

    A field method to determine three dimensional infiltrability of vineyard soils

    Item type: Journal Article • Journal: South African Journal of Plant and Soil
    A method is described to measure water intake from a small, shallow pond in which a 5 mm constant water head is maintained. Since water is supplied to the soil at near atmospheric pressure, infiltrability rather than infiltration rate is...
  5. Genetic and morphological variation of the lanternfish <em>Lampanyctodes hectoris</em> (Myctophiformes: Myctophidae) off southern Africa

    Genetic and morphological variation of the lanternfish <em>Lampanyctodes hectoris</em> (Myctophiformes: Myctophidae) off southern Africa

    Item type: Journal Article • Journal: South African Journal of Marine Science
    Genetic and morphological variation within the southern African population of Lampanyctodes hectoris was analysed. A total of 15 enzymes, encoding 22 isozyme loci, was examined (n = 327); seven were polymorphic. The percentage of polymorphic loci ranged from 13.6 to...
  6. Micro‐site influence on seed longevity and seedling emergence of a bunchgrass <em>(Themeda triandra)</em> in a semi‐arid savanna

    Micro‐site influence on seed longevity and seedling emergence of a bunchgrass <em>(Themeda triandra)</em> in a semi‐arid savanna

    Item type: Journal Article • Journal: African Journal of Range & Forage Science
    The influence of micro‐site (shaded, exposed, buried) on the seed longevity and seedling emergence of Themeda triandra was tested using experimental seed banks. Deep shade considerably reduced soil surface temperature. Seeds did not persist in any micro‐site for longer than...
  7. Aspects of the seed ecology of Acacia karroo in the Eastern Cape, South Africa

    Aspects of the seed ecology of Acacia karroo in the Eastern Cape, South Africa

    Item type: Journal Article • Journal: African Journal of Range & Forage Science
    Seed ecology may play a role in the widespread increase of Acacia karroo in savanna and grassland. Accordingly, fecundity, predation, mortality by fire, dispersal by livestock, and seed longevity were studied. Seed production per tree (P of pod production, pods...
  8. Longevity of the Seychelles Fody <em>Foudia sechellarum</em>

    Longevity of the Seychelles Fody <em>Foudia sechellarum</em>

    Item type: Journal Article • Journal: Ostrich: Journal of African Ornithology
    The Seychelles Fody Foudia sechellarum, which occurs on six islands in the Seychelles, has been well ringed over several decades in order to obtain population estimates for the species, and morphological descriptions and measurements. Annual survival estimates for the species...
  9. Currents along the Tsitsikamma coast, South Africa, and potential transport of squid paralarvae and ichthyoplankton

    Currents along the Tsitsikamma coast, South Africa, and potential transport of squid paralarvae and ichthyoplankton

    Item type: Journal Article • Journal: African Journal of Marine Science
    In July 1998, a bottom-mounted Acoustic Doppler Current Profiler was deployed at 36m depth in the centre of the Tsitsikamma National Park on the eastern Agulhas Bank, South Africa. The purpose was to investigate transport of chokka squid Loligo vulgaris...
  10. First Lagrangian ROMS–IBM simulations indicate large losses of chokka squid <em>Loligo reynaudii</em> paralarvae from South Africa's Agulhas Bank

    First Lagrangian ROMS–IBM simulations indicate large losses of chokka squid <em>Loligo reynaudii</em> paralarvae from South Africa's Agulhas Bank

    Item type: Journal Article • Journal: African Journal of Marine Science
    Present knowledge of ocean currents based on in situ observation and models suggests that passive biological material such as eggs and larvae can be advected offshore away from the Agulhas Bank, South Africa, and hence removed from the ecosystem on...
