      • Problem Dinoflagellates in Algoa Bay 

        du Preez, D. (2015-03-31)
        Dinoflagellate blooms, also known as red tides, are a worldwide phenomenon. The frequency of these blooms has been increasing in recent years and large dinoflagellate blooms have been seen in areas where they have not been ...
      • Re-evaluation of a riparian restoration experiment in the Western Cape Province: status 8 years down the line 

        Pretorius, M (2007-05-11)
        In 1998, a study was initiated to assess the relative effectiveness of three different sowing treatments for reducing soil erosion and restoring indigenous vegetation cover after alien clearing in the Western Cape. The ...
      • Reproductive biology of Turbo sarmaticus at Dwesa-Cwebe Nature Reserve 

        Yekwayo, Inam (2010-11-26)
        The reproductive biology of giant periwinkle (Turbo sarmaticus) was investigated using gravimetric method. Samples were randomly collected from Dwesa-Cwebe Nature Reserve during spring low tide from June 1996 to July 1997 ...
      • Resource availability as a key driver of Argentine ant, Linepithema humile, invasion success 

        Phair, D.J. (2014-02-10)
        Resource availability has frequently been identified as a key driver for the successful invasion of non-native ants. Essential macronutrients for ant colony survival include protein and carbohydrates. Long term studies ...
      • The response of benthic macroinvertebrates and adult Odonata to alien invasive clearing 

        Modiba, Rifilwe Victor (2012-03-28)
        Department of Water Affairs has been removing invasive alien riparian trees along the riparian zones through Working for Water programme since 1995. In this study we assess the progress of the programme by studying the ...
      • The response of native ant communities to an alien invasive species (Chromolaena odorata) - the effect of temporal variation in invasion and clearing 

        Julius, Rolanda (2008-05-28)
        Alien invasive species can potentially alter each and every trophic level of the ecosystem through its action of habitat change. Chromolaena odorata is an aggressive invader that has the widest distribution of all alien ...
      • The response of some families of ground-dwelling beetles to a landscape mosaic in the Soutpansberg Mountains 

        Mauda, Evans; Schoeman, Colin Stefan (2013-08-01)
        Various ground-dwelling invertebrates respond differently to changes in the structure of the landscape. Implementation of a mechanistic approach to landscape ecology is essential to deriving generalizations about how spatial ...
      • A review of five vertebrate invaders in South Africa 

        Faber, M. (2010-12-02)
        Invasive alien species are listed as one of three major threats to global biodiversity. They can be detrimental through affecting the function and structure of ecosystems and degrading human health. Five vertebrate species ...
      • Sagartia ornata in the West coast national park 

        Swarts, C. (2014-02-04)
        Data collected during Cheruscha Swarts honours project
      • Scorpion diversity along a strong environmental gradient and an evaluation of sampling protocols 

        Gelebe, Vhuhwavho (2013-02-05)
        ABSTRACT Scorpions are an important component of the ground-dwelling invertebrate fauna, and may have value as indicators of ground-dwelling invertebrate diversity. However, some level of understanding of which factors ...
      • Seed bank dynamics and the role of mutualisms in the early-life ecology of emerging alien invasive plants: Acacia paradoxa in South Africa 

        Mazibuko, Dickson (2010-11-17)
        Seed banks provide a persistent source of propagules for recruitment and establishment and are a very important factor for the success in recruitment, persistence and spread of many invasive alien plants worldwide. Where ...
      • Seed bank status and dynamics of Acacia saligna at two sites in the Western Cape, South Africa 

        Strydom, M.; Esler, K.J.; Wood, A.R. (2010-09-23)
        Acacia saligna is the most damaging invasive species in the coastal lowlands of the south-western Cape. The gall rust fungus, Uromycladium tepperianum, has been highly successful as a biological control agent for A. ...
      • Settlement of Perna perna larvae in successful and unsuccessful rehabilitation sites in Coffee Bay 

        Ngalwa, Musa (2010-11-26)
        Settlement is a major determinant of intertidal organisms. Arrival and attachment on suitable substrata are essential requirements for species survival. Populations of the brown mussel Perna perna in the former Transkei ...
      • Should we lump or split? The case of the Pheidole megacephala species group along a strong environmental gradient in the Soutpansberg Mountains in the Limpopo Province, South Africa? 

        Simba Lavhelesani Dembe (2013-03-26)
        Pheidole megacephala (Fabricius, 1793) is an ant species of the family Formicidae that includes at least ten subspecies. It is one of the three species that are found across the Soutpansberg Mountain. The mountain is ...
      • Silver wattle (Acacia dealbata) alters arthropod assemblages in the Sani Pass region of the Drakensberg 

        Coetzee, B.W.T. (2007-05-10)
        Invasive alien plants constitute a significant threat to global biodiversity. Alien invasive plants are currently invading natural ecosystems in South Africa but their impacts on biodiversity are poorly understood, ...
      • A socio-ecological study of the Wolfgat Nature Reserve and the neighbouring Mitchells Plain community 

        Abrahams, Brent (2014-01-27)
        Wolfgat Nature Reserve, experiences a severe security threat level due to violent crime as a result of its location and the social challenges facing the Cape Flats community of Mitchell’s Plain. The WNR has for a long ...
      • Spatial pattern formation of a predator-prey system with predator pursuit and prey evasion 

        Potgieter, Linke (2010-09-16)
        Spatial synchrony, which can be result of high migration, can increase the risk of regional extinction, and as a result reduce metapopulation persistence. Coupled patch models, based on a within-patch discrete growth ...
      • Species richness of alien plants across protected areas in northern KwaZulu-Natal, South Africa: environmental and anthropogenic correlates 

        van der Westhuizen, R (2007-05-10)
        Previous studies have highlighted several factors that contribute to the invasiveness of a reserve, e.g. the native plant species richness, the age of the reserve and human population densities next to reserves. Some areas ...
