      • The restoration potential of fynbos riparian seed banks following alien clearing 

        Vosse, S (2007-05-04)
        Riparian areas contribute significantly to the spread of many invasive alien tree species which alter the ecosystem by bringing about significant water loss and changing the natural flow regimes of the system. For this ...
      • Avifaunal responses to environmental conditions and land-use changes in South Africa: diversity, composition and body size 

        Greve, M. (2007-06-14)
        In macroecology, body sizes in assemblages have traditionally been investigated from two perspectives: body size frequency distributions (BSFDs) and geographic variation in body size. Neither of these has been investigated ...
      • Effects of Chromolaena odorata on mammalian biodiversity in Hluhluwe-iMfolozi Park, South Africa 

        Dumalisile, Lihle (2008-03-31)
        This study investigated the effects of the Triffid weed Chromolaena odorata on small and large mammals in Hluhluwe-iMfolozi Park. C. odorata is a widespread invasive alien plant that poses threat to the highly maintained ...
      • Spider community responses to Chromolaena odorata invasion, grassland type and grazing intensities 

        Mgobozi, Mandisa P. (2008-05-06)
        Biological indicators measure components of the biota and are used to give general information about complex ecosystems in which they occur, playing key roles in conservation planning and management. This study illustrates ...
      • Impacts of the invasive reed Arundo donax on biodiversity at the community-ecosystem level 

        Guthrie, Gene (2008-05-08)
        Arundo donax is an invasive species that mostly impacts on sensitive riparian ecosystems. In California, USA, Arundo worsens flood effects, outcompetes and displaces indigenous plant and animal species, creates fire hazards, ...
      • The Restoration Potential of Fynbos Riparian Seed Banks after Alien Clearing 

        Vosse, S (2008-06-24)
        Riparian areas are highly complex systems with varying levels of disturbance that are highly susceptible to invasion by alien plants. Once invaded, riparian areas play a major role in the dispersal and spread of invasive ...
      • Synergistic impact of invasive alien trees and the alien Argentine ant on local ant assemblages in the Cape Floristic Region 

        Schoeman, Colin (2008-07-03)
        There is worldwide concern over the impact of invasive alien organisms on indigenous biota. Alien tree invasions have reached major proportions in the global biodiversity hotspot, the Cape Florsitic Region (CFR). Furthermore, ...
      • Arthropod assemblages in a savanna invaded by Opuntia stricta (Cactaceae) in the Kruger National Park, South Africa 

        Harris, Kyle Robert (2009-08-13)
        Invasive alien species are considered the second greatest threat to global biodiversity after habitat loss. South Africa is not immune from such threats and it is estimated that 10 million ha (8.28 %) of land has been ...
      • The role of hydrocarbons in nestmate recognition of the Invasive Argentine ant, Linepithema humile (Mayr) 

        Mothapo, Palesa Natasha Jr; Wossler, Theresa Jr (2009-12-04)
        Argentine ant behvaiour and chemical communication signals.
      • Alien grass invasion of Renosterveld: Influence of soil variable gradients 

        Muhl, Sara Ann (2010-09-23)
        This thesis examines the role of agricultural activity in the process of invasion of west coast renosterveld fragments by annual alien grass species. This highly endangered vegetation type has less than 5% remaining, it ...
      • The extent of woody plant invasion in selected sites of the communally managed Molopo District, North West Province. 

        Mogodi, Phemelo, P. (2010-11-29)
        Woody plant invasion (bush encroachment) is a problem in the semi arid communal areas of the North West Province which had been affecting the Molopo Area as early as 1960. It affects the livelihoods of the communal farmer ...
      • History and status of oyster exploitation and culture in South Africa, and the role of oysters as vectors for marine alien species 

        Haupt, T.M. (2010-12-02)
        In South Africa, both wild and cultivated oysters are consumed. Edible wild oysters include Striostrea margaritacea, Saccostrea cucullata, Ostrea atherstonei and O. algoensis and all occur along the South and East coasts. ...
      • Wildflower farming on the Agulhas Plain 

        Treurnicht, Martina Jr (2011-01-26)
        This data reports on various aspects related to wildflower farming on the Agulhas Plain. Firstly, by administering a questionnaire, the extent and application of farming practices was investigated. Additionally, the opinion ...
      • Distribution and bait preference of the Argentine ant in natural vegetation 

        Vorster, Carlien (2011-11-17)
        Since its introduction in 1898 into South Africa, the Argentine ant, Linepithema humile, has invaded human-occupied areas (i.e. urban and agricultural areas) and natural areas characterised by few, if any, anthropogenic ...
      • Invasive Australian acacias: reproductive biology and effects on native plant-pollinator communities in Cape fynbos 

        Gibson, Michelle (2012-01-18)
        My master’s research combines aspects of pollination biology and invasion biology to explore the invasive predictors and impacts of a globally invasive group of plants – Australian acacias. Specifically, I investigate the ...
