An analysis of primary and secondary production in lake Kariba in a changing climate
Ndebele-Murisa, Mzime R. (University of Western Cape, 2011)Analysis of temperature, rainfall and evaporation records over a 44-year period spanning the years 1964 to 2008 indicates changes in the climate around Lake Kariba. Mean annual temperatures have increased by approximately ... -
Can bio fortified plants accumulate trace elements essential to the growth and development of humans?
Müller, Francuois Lloyd F. (University of the Western Cape, 2013)Micronutrient and trace element deficiencies are a problem affecting nearly two billion people globally. The people affected the most by these deficiencies are those living in poor and rural communities in the developing ... -
Can biofortified plants accumulate trace elements essential to the growth and development of humans?
Müller, Francuois Lloyd (University of the Western Cape, 2013)This study aimed to determine the nutrient content (Co, Cr, F, I, Se and V) of various vegetable based food items collected from the Cape Town area in the Western Cape Province of South Africa. This was done to determine ... -
The ecohydrology of the Franschoek Trust Wetland: water, soils and vegetation
Kotzee, Ilse (University of the Western Cape, 2010)The research was driven by a need to increase the knowledge base concerning wetland ecological responses, as well as to identify and evaluate the factors driving the functioning of the Franschhoek Trust Wetland. An ... -
The ecohydrology of the Fransehoek Trust Wetland: water, soils and vegetation.
Kotzee, Ilse (University of the Western Cape, 2010)The research was driven by a need to increase the knowledge base concerning wetland ecological responses, as well as to identify and evaluate the factors driving the functioning of the Franschhoek Trust Wetland. An ... -
The Effects of Cadmium and Lead on Phaseolus vulgaris
Brandt, Clarissa (University of the Western Cape, 2012)The demand for better quality produce by consumers is on the increase, as higher heavy metal concentrations pose a problem in agriculture. They result in decreased yield and unsuitable food for human consumption. This ... -
The effects of clipping and burning on the allocation of total nonstructural carbohydrates and selected mineral nutrients in Imperata cylindrica (L.) Raeuschel
Mitchell, Faghrie (University of the Western Cape, 1999)The rhizomatous grass, Imperata cylindrica, occurs in the Cape Flats Nature Reserve (CFNR), South Africa. It is recognised globally as a weed of crop plants. The response of this weed to defoliation, in the forms of clipping ... -
Empirical and model derived respiration responses to climate in different soils of an arid South African ecosystem
Nyaga, Justine Muhoro (2009)This study examined the magnitude of soil CO2 efflux in an arid South African ecosystem, the flux responses as well as those of key limiting nutrients to soil temperature increases and moisture reductions consistent with ... -
Land use practices and their impact on the water quality of the Upper Kuils River (Western Cape Province, South Africa)
Mwangi, François Ngera (University of Western Cape, 2014)The water quality in many Cape Town Rivers and streams is a major challenge. Kuils River is subject to multiple land use impacts from upstream to downstream because of rapid urbanization in its catchment area. The main ... -
Lichen thermal sensitivities, moisture interception and elemental accumulation in an arid South African ecosystem
Maphangwa, Khumbudzo Walter (University of the Western Cape, 2010)Elevated temperatures accompanying climate warming are expected to have adverse effects on sensitive lichen species. This premise was examined by measuring the sensitivity of different lichen species to elevated temperatures ... -
Linking biology and sustainable livelihoods to the proposed establishment of community -based Eucheumoid farming in southern Kenya
Wakibia, Joseph .G (University of the Western Cape, 2005)Growth rates of three commercial eucheumoids: brown Eucheuma denticulatum and green and brown Kappaphycus alvarezii were studied at three sites (Gazi Bay, Kibuyuni and Mkwiro) in southern Kenya. The study was conducted ... -
Monitoring of heavy metals in the Bottelary River using Typha capensis and Phragmites australis
Ma, Ying (University of the Western Cape, 2005)The aim of this study was to use plants to determine the degree of heavy metal contamination in water and sediments in order to effectively monitor and provide possible recommendation to improve the water quality in the ... -

Monitoring water quality with riparian trees along the Berg River, Western Cape
Ruiters, Melissa (University of the Western Cape, 2012)Heavy metals and nutrients have long been regarded as pollutants to freshwater ecosystems. These elements have a detrimental effect on plants, animals and the water quality of rivers in South Africa. The Berg River flows ... -
The relevance of fog and dew precipitation to succulent plant hydrology in an arid South African ecosystem
Matimati, Ignatious (2009)Fog and dew interception and utilization by plant canopies remains one of the least considered aspects of vegetation studies at any scale yet the few studies that have been conducted point to their considerable influence ... -
Salinity of irrigation water in the Philippi farming area of the cape flats, Cape Town, South Africa
Aza-Gnandji, Cocou Davis Ruben (University of the Western Cape, 2011)This research investigated the nature, source and the spatial variation of the salinity of the water used for irrigation in the urban farming area of Philippi, which lies in the Cape Flats region of the Cape Town Metropolitan ... -
Salt tolerance and modification of wheat salt resistance by plant hormones
Adam, Muftah Ahmed (University of the Western Cape, 2004)The history of salt tolerance and the factors effecting salt resistance of plants were literature surveyed, and it was concluded that ion concentration, salt accumulation, compatible solutes and the genetic traits play a ... -
Sources of heavy metals in vegetables in Cape Town and possible methods of remediation
Meerkotter, Marÿke (University of the Western Cape, 2012)Cape Town includes two vegetable farming areas within the city limits, the Joostenbergvlakte/Kraaifontein area and the Philippi area. Both areas supply produce to local markets and further afield. Sporadically, high levels ... -
