    Patterns of plant species diversity in fynbos vegetation, South Africa (1980)

    Notes: Summary In fynbos vegetation of the southwestern Cape Province, South Africa, plant species diversity relations (alpha and beta diversity) are studied in a local context of variation across two interacting gradients, a temporal gradtent (age after fire) and an altitudinal gradient. Alpha diversity is lower in the older fynbos at high and low altitudes. This can be related to the nature of succession in fynbos. The lowest alpha diversity occurs in the low altitude old vegetation. This appears to occur because of the decrease of understory cover due to overtopping by tall shrubs and tall restioids. Beta diversity is due more to the altitude factor than to fire. This can also be related to the nature of fynbos succession. In general the trends shown by alpha and beta diversity can be explained with reference to fynbos succession, the regenerating strategies after fire (seed vs. vegetative) and the effect of the overstory on the understory.

    The forest communities of Table Mountain, South Africa (1977)
    Springer
    Plant ecology 34 (1977), S. 105-115

    ISSN: 1573-5052

    Notes: Summary The forest communities of Table Mountain have been classified using the Braun-Blanquet technique together with numerical analysis. Three major communities, termed associations, have been recognised. Some of these associations have been subdivided. Each community has been described in terms of floristic, structural and environmental factors. The dominant factors affecting the distribution of forest communities appear to be moisture conditions, soil rockiness and soil depth. Information from other South-Western Cape forest areas is discussed. The forests from Table Mountain are similar to these. However, two forest communities are not found on the Cape Peninsula and extensive areas of Cassine dominated forest on deep soils referred to as the Scolopia mundii — Cassine capensis varlant do not appear to be foun outside Orange Kloof.

    High performance gel filtration using monodisperse highly cross-linked agarose as a one-step system for mucin purification (1993)

    Notes: High performance gel filtration on monodisperse cross-linked agarose (Superose 6) has been assessed as a system for purification of mucus glycoproteins. Comparison with the conventional two-step purification of mucus glycoprotein by Sepharose CL4B gel filtration followed by caesium chloride density gradient centrifugation shows that purification by high performance gel filtration is at least as thorough, yielding mucin that is free from non-mucin glycoproteins as defined by buoyant density, mobility on sodium dodecyl sulphate-polyacrylamide gel electrophoresis and absence of Concanavalin A binding (mannose-containing) material. This technique allows mucus glycoprotein to be purified from lyophilized crude mucin in 120 min compared with approximately 72 h using the conventional techniques. This makes the comparative study of mucus glycoprotein changes in disease states much more feasible.
