  1. Molecular characterization of cassava brown streak viruses in Mozambique
    Amisse, Jamisse Jose Goncalves, 2014-03-03T09:22:38Z
    Cassava brown streak disease (CBSD) caused by two distinct ssRNA virus species (CBSV and UCBSV of genus Ipomovirus, family Potyviridae) and transmitted by whitefly (Bemisia tabaci), is a major constraint to cassava production in Africa, including Mozambique. In this research, two studies were conduc ...

  4. Can MODIS NDVI measurements be used to predict zebra (Equus burchelli) foraging patterns?
    Zinn, Andrew David., 2014-03-03T09:46:03Z
    As an indicator of above ground net primary productivity, the Normalised Difference Vegetation Index (NDVI) has been identified as important tool in understanding the resource requirements and distribution patterns of large herbivores. The efficacy of NDVI as an ecological tool is however, strongly ...
  5. Motivation, work values, organisational commitment and job satisfaction : age and generational cohort effects.
    Nkomo, Emmanuel, 2014-03-03T09:54:01Z
    Since the year 2000, younger workers born after 1980 have been entering the South African workforce in large numbers. The experienced Baby Boomer generation, born between 1945 and 1964 has started leaving the workplace in retirement. With organisations currently facing the challenge of skills shorta ...
  6. The reproductive biology and habit at requirements of aloe peglerae, a montane endemic aloe of the Magaliesberg mountain range, South Africa.
    Arena, Gina, 2014-03-03T12:03:03Z
    In this study I investigated the reproductive biology and pollination ecology of Aloe peglerae, an endangered endemic succulent species of the Magaliesberg Mountain Range in South Africa. The aim was to determine the pollination system of A. peglerae, the effects of flowering plant density on plant ...
  7. Modern predators : the science, sovereignty, and sentiment of wildlife conservation in Zambia.

    This dissertation presents the suspicions and tensions encountered during ethnographic fieldwork with (what I call) the Predator Project Zambezi (PPZ), a WWF-funded research and conservation organization based in Zambia. It extrapolates the broader contexts of this uneasiness and situates it with ...
  8. Depositional slope surface of the western margin of the Nylsvlei, South Africa : active piedmont aggradation and sedimentation processes.
    Burri, Nicole M., 2014-03-03T12:19:59Z
    The Nyl River and its floodplain are situated on the eastern foothills of the Waterberg mountain range in the Limpopo Province of South Africa.
