  1. Yield assessment of advanced wheat breeding lines the Winter Rainfall Region of South Africa. I. Homogeneity of the region

    Yield assessment of advanced wheat breeding lines the Winter Rainfall Region of South Africa. I. Homogeneity of the region

    Item type: Journal Article • Journal: South African Journal of Plant and Soil
    The major wheat-producing areas in the Winter Rainfall Region are geographically divided into the Rûens and Swartland. The question whether the Rûens and Swartland should be regarded as non-similar areas, each meriting its own wheat-breeding programme, is considered. Correlations between...
  2. Investigating the use of satellite selection sites in soybean (<em>Glycine max</em> (L.) Merr.) breeding

    Investigating the use of satellite selection sites in soybean (<em>Glycine max</em> (L.) Merr.) breeding

    Item type: Journal Article • Journal: South African Journal of Plant and Soil
    A satellite selection site is a decentralized selection environment that could be employed to expand the influence of existing breeding programmes to additional target environments. This study was designed to establish whether it would be possible to achieve site-specific adaptation...
  3. An overview of the context and scope of wheat (<em>Triticum aestivum</em>) research in South Africa from 1983 to 2008

    An overview of the context and scope of wheat (<em>Triticum aestivum</em>) research in South Africa from 1983 to 2008

    Item type: Journal Article • Journal: South African Journal of Plant and Soil
    The domestic requirement for wheat in South Africa is approximately 2.8 million tons and annually the shortfall on local production is imported to meet the demand. During the past 25 years two distinct wheat marketing mechanisms characterised the wheat industry,...
  4. Climate variability and impacts on east African livestock herders: the Maasai of Ngorongoro Conservation Area, Tanzania

    Climate variability and impacts on east African livestock herders: the Maasai of Ngorongoro Conservation Area, Tanzania

    Item type: Journal Article • Journal: African Journal of Range & Forage Science
    East African pastoral adaptation and vulnerability to climate variability and climate change is assessed, using data from decisionmaking processes and ecological data of the Maasai of Ngorongoro Conservation Area as an example. The paper uses integrated modeling, linking PHEWS, a...
  5. Climate change perceptions, drought responses and views on carbon farming amongst commercial livestock and game farmers in the semiarid Great Fish River Valley, Eastern Cape province, South Africa

    Climate change perceptions, drought responses and views on carbon farming amongst commercial livestock and game farmers in the semiarid Great Fish River Valley, Eastern Cape province, South Africa

    Item type: Journal Article • Journal: African Journal of Range & Forage Science
    There is increasing evidence that climate change will be one of the primary challenges facing future development and agriculture. Farmers, whether crop or livestock farmers, will be faced with tradeoffs and constraints as climate change exposes them to greater risk...
  6. Positive Adaptation in a Community of Postgraduate Students: Applying the Mmogo-method™

    Positive Adaptation in a Community of Postgraduate Students: Applying the Mmogo-method™

    Item type: Journal Article • Journal: Journal of Psychology in Africa
    This study explored the experiences of postgraduate psychology students exposed to continuous challenges and described their positive adaptation as a community. Three males and 14 females (age range: 23–30 years; 1 black, 3 coloured, 2 Indian and 11 white) took...
  7. Resilience in Families Adapting to Autism Spectrum Disorder

    Resilience in Families Adapting to Autism Spectrum Disorder

    Item type: Journal Article • Journal: Journal of Psychology in Africa
    This study explored adjustment and adaptation in families living with Autism Spectrum Disorder (ASD). Data on family resilience were collected from 19 biological mothers of children with ADS. The data were analysed qualitatively and quantitatively to yield information on factors...
  8. Phytoplankton production and adaptation in the vicinity of Pemba and Zanzibar islands, Tanzania

    Phytoplankton production and adaptation in the vicinity of Pemba and Zanzibar islands, Tanzania

    Item type: Journal Article • Journal: African Journal of Marine Science
    Phytoplankton production and physiology were investigated at six selected locations during a research cruise in early October 2007 in Tanzanian coastal waters. The dataset included photosynthesis– irradiance and active fluorescence parameters, phytoplankton absorption coefficients, and pigment concentrations. Primary production was...
  9. Phenotypic plasticity and local adaptation in two extreme populations of <em>Acacia karroo</em>

    Phenotypic plasticity and local adaptation in two extreme populations of <em>Acacia karroo</em>

    Item type: Journal Article • Journal: African Journal of Range & Forage Science
    Phenotypic plasticity is the effect of growth variability in response to different environmental conditions. Adaptive phenotypic plasticity is more specific; it is the ability of a single genotype to produce an array of phenotypes depending on the environmental extent. We...
  10. Bouncing forward: families living with a type I diabetic child

    Bouncing forward: families living with a type I diabetic child

    Item type: Journal Article • Journal: South African Family Practice
    Background: Despite the multitude of challenges that families living with a child with diabetes face, they have been found to adapt to such an extent that diabetes is viewed as a manageable condition. This study was concerned with the factors...
