    From HIV prevention to reproductive health choices: HIV/AIDS treatment guidelines for women of reproductive age

    Item type: Journal Article • Journal: African Journal of AIDS Research
    In South Africa, the private sector has responded to the HIV epidemic by providing treatment in the form of highly active antiretroviral therapy (HAART). The private sector has paved the way for policy and treatment regimens, while the public sector...
  2. Describing gonad development and gametogenesis in southern Africa’s endemic box jellyfish <em>Carybdea branchi</em> (Cubozoa, Carybdeidae)

    Describing gonad development and gametogenesis in southern Africa’s endemic box jellyfish <em>Carybdea branchi</em> (Cubozoa, Carybdeidae)

    Item type: Journal Article • Journal: African Journal of Marine Science
    Information on the reproductive development of species of box jellyfish (class Cubozoa) is poor globally, despite their significance as potent stingers and worrying projections about range expansions. While most species are confined to tropical and subtropical waters, the South African...
  3. The Changing Landscape—is there Room for Forestry in the New South Africa?

    Item type: Journal Article • Journal: South African Forestry Journal
    South Africa is going through a period of radical change, and traditionally disadvantaged people are expecting access to resources and opportunities that have thus far been denied them.
  4. Soil factors affecting tree growth and root development in a citrus orchard

    Soil factors affecting tree growth and root development in a citrus orchard

    Item type: Journal Article • Journal: South African Journal of Plant and Soil
    Tree- and root-growth parameters correlated well with a number of soil properties Useful relationships were established between unconfined penetrometer resistance, air capacity (at FWC), tree growth and root development.
  5. Communal land use and the ‘tragedy of the commons’: Some problems and development perspectives with specific reference to semi‐arid regions of southern Africa

    Item type: Journal Article • Journal: Journal of the Grassland Society of Southern Africa
    Traditional communal farming in southern Africa has often been described as unproductive and directly responsible for regional poverty and vegetation degradation. Each aspect of this argument rests on a set of unchallenged assumptions concerning the nature of communal farming. Studies...
  6. Veld management in the communal areas of Ciskei

    Item type: Journal Article • Journal: Journal of the Grassland Society of Southern Africa
    Veld management in Ciskei is based predominantly on a communal land tenure system, and livestock is produced under a ‘Group Ranch’ system. Stocking rates are excessively high and consequently veld degradation is severe, resulting in a lowered carrying capacity and...
  7. Effect of planting date on the phenology, seed yield, and fatty acid composition of three sunflower <em>(Helianthus annuus</em> L.) cultivars

    Effect of planting date on the phenology, seed yield, and fatty acid composition of three sunflower <em>(Helianthus annuus</em> L.) cultivars

    Item type: Journal Article • Journal: South African Journal of Plant and Soil
    Four planting dates (early October to mid-January) were used to obtain a range of environmental conditions for growing three sunflower cultivars. The effect of planting date on phenological development was small compared to that of genotype though the hybrid S0404...
  8. 'n Nuwe benadering tot die bepaling van hitte-eenhede vir sonneblom

    'n Nuwe benadering tot die bepaling van hitte-eenhede vir sonneblom

    Item type: Journal Article • Journal: South African Journal of Plant and Soil
    Die konvensionele metode vir die bepaling van hitte-eenhede is vergelyk met 'n nuwe benadering. Data uit sewe kultivarproewe insluitende daaglikse maksimum en minimum temperature is gebruik om die hitte-eenhedevereistes van drie kultivars te bepaal. Twee vergelykings is gebruik, een verteenwoordig...
  9. Refinement and validation of the PUTU wheat crop growth model 1. Phenology

    Refinement and validation of the PUTU wheat crop growth model 1. Phenology

    Item type: Journal Article • Journal: South African Journal of Plant and Soil
    The phonological submodel of the PUTU wheat crop growth model was refined to account for the variation in sensitivity to vernalization and photoperiod. Crop development rate was simulated in five phenological phases making use of temperature and photoperiod. Base values...
  10. Die invloed van verskillende waterregimes op Up-to-date aartappels I. Vegetatiewe ontwikkeling, fotosintesetempo en stomatadiffusieweerstand

    Die invloed van verskillende waterregimes op Up-to-date aartappels I. Vegetatiewe ontwikkeling, fotosintesetempo en stomatadiffusieweerstand

    Item type: Journal Article • Journal: South African Journal of Plant and Soil
    Drie grondwaterregimes (20, 50 en 70% onttrekking van plantbeskikbare water) is gedurende herfsaanplan- tings in 1987 en 1988 op Up-to-date aartappels toegepas om die invloed daarvan op groei en ontwikkeling te ondersoek. Twee fisiologiese parameters van plantwaterstremming, naamlik, fotosintesetempo en...
