  1. Protected nearshore shallow and deep subtidal rocky reef communities differ in their trophic diversity but not their nutritional condition

    Protected nearshore shallow and deep subtidal rocky reef communities differ in their trophic diversity but not their nutritional condition

    Item type: Journal Article • Journal: African Journal of Marine Science
    Large physical changes that alter reef macrobenthos and fish assemblages occur with increasing depth, so the biological processes that regulate communities at different depths are expected to diverge. We used analyses of stable isotopes (δ13C and δ15N) and fatty acids...
  2. Yield Regulation in the Knysna Forests

    Item type: Journal Article • Journal: South African Forestry Journal
    A yield regulation system for the indigenous forest of the Southern Cape is described. With the system an attempt is made to approach optimum sustainable yield levels, subject to conservation principles. Complexities of forest dynamics and growing stock sampling constraints...

    The performance of young woolled sheep was markedly better when grazing Japanese radish early in winter, when more leaf was available .Continuous grazing resulted in better performance than rotational or zero grazing.
  4. Effect of nitrogenous fertiliser on the yield of various annual fodder legumes nodulated by effective rhizobia

    Effect of nitrogenous fertiliser on the yield of various annual fodder legumes nodulated by effective rhizobia

    The practice of applying N fertiliser to legumes at seeding was critically studied in Lupinus angustifolius, L. albus, Ornithopus sativus, Pisum sativum arvense, Vicia dasycarpa and Vigna unguiculata in a series of field and pot trials. In addition, the theory...

    Item type: Journal Article • Journal: South African Journal of Plant and Soil
    Voandzeia subterranea and Cajanus cajan are important pulse crops in tropical and subtropical Africa and their drought hardiness and ability to utilize poor soils are inter alia reasons for this popularity. Both species hold considerable promise as crops in South...
  6. Growth and production of <em>Vicia dasycarpa</em> Ten., Namoi as influenced by an oat support crop and nitrogen fertilizer

    Growth and production of <em>Vicia dasycarpa</em> Ten., Namoi as influenced by an oat support crop and nitrogen fertilizer

    Item type: Journal Article • Journal: South African Journal of Plant and Soil
    The performance of Vicia dasycarpa cv. Namoi in pure stand and mixed with oats at four densities, grown at three levels of N fertilizer, was studied in the field under irrigation. Both the increased plant density of oats and N...

    FRESHWATER NEMATODES FROM SOUTH AFRICA 3. <em>TOBRILUS</em> ANDRÁSSY, 1959

    Item type: Journal Article • Journal: Journal of the Limnological Society of Southern Africa
    During a survey of freshwater nematodes in South Africa, six species of Tobrilus Andrássy, 1959 were encountered. The six species, four of which are new to science, are described and figured, viz. Tobrilus annetteae, n.sp.; T. heptapapillatus n.sp.; T. stefanskii...
