Population and Physiological Studies of selected Geophytics Species of Lowland Coastal Fynbos in the Southwestern Cape
(University of the Western Cape, 1990)Population and physiological studies were conducted in coastal fynbos in the South-western Cape. Minor ecophysiological studies were also conducted such as the soil moisture content and pH. Two species, viz. Haemanthus ... -
a comparative study of the influence of different copper concentrations on the growth, chemical composition and activities of certain copper containing enzymes in atriplex nummularia lindl. and a. vestita (thunb.) Aell.
(University of the Western Cape, 1990)The total amount of native copper in soil depends on the amount of copper in the parent material (Tisdale .et .al.1968). It is usually in greater concentration in the soil than in parent rock because of weathering of the ... -
A critical analysis of aspects pertaining to the teaching of the ecology section of the standard eight biology syllabus.
(University of the Western Cape, 1991)In this study an attempt has been made to investigate how the Ecology section (suitable for fostering awareness and concern for the environment) of the standard eight Biology syllabus is taught. Since fieldwork and ... -
Biomonitoring as a means to determine the pollution level in Stellenbosch
(University of the Western Cape, 1991)A pollution survey was done in Stellenbosch, along two transects. One was south-east and the north-east of the Oorrobrick brickfield the focal point of this study. Pine and Oak trees, chasman the leaves and lichens were ... -
Perceptions of first year Biology students at a college of education towards the relevance of population dynamics as prescribed for current biology syllabusses at matriculation level in South African schools
(University of the Western Cape, 1992)Throughout this research, an attempt has been made to assess the perceived relevance, if any, of the Population Dynamics topic of the standard ten Biology syllabus, especially of those standard ten pupils enrolling as ... -
Vegetation relationships of priority conservation sites on the Cape flats
(University of the Western Cape, 1992)The physical environment of the cape Frats is outlined. The plant communities of twenty-one priority conservation sites are classified. Twenty-five communities, grouped into 15 associations, 8 alliances, 4 orders, 2 ... -
Effect of simulated acid rain on seed germination and on growth and mineral nutrition of Lycopersicon esculentum var. Red kaki
(University of the Western Cape, 1993)The phenomenon of acid rain is not new. It has been active for more than a billion years (Abelson, 1983). The term "acid rain" was introduced as early as 1872 by Robert Angus Smith, the world's first air pollution control ... -
A study of the pollination biology of the (gyno)dioecious fig, Ficus capreifolia Del. (Moraceae)
(University of the Western Cape, 1994)The pollination biology of Ficus pareidolia Del. was studied. Ficus pareidolia is a (gyno)dioecious species with separate male and female plants bearing male and female syconia respectively. Male syconia had staminate ... -
Geographical studies on the interaction between the pear limpet, patella cochlear, and the encrusting coralline alga, spongites yendoi
(University of the Western Cape, 1995)The territorial pear limpet, Patella cochlear, occurs along the South and Southern West coasts of South Africa, while one of its primary prey, the encrusting coralline alga, Spon~ites yendoi, occurs much further north along ... -
Triterpene glycosides chemically defend the south african kelp bed sea cucumber, Pseudocnella insolens (echinodermata : holothu roidea), against predation.
(University of the Western Cape, 1997)The small, subtidal sea cucumber, Pseudocnella insolens appears to have no obvious protection from predation, yet it occurs in dense colonies covering rocky areas and appears to have few predators. Laboratory-based feeding ... -
Aspects of moulting of the South African West Coast rock lobster, Jasus lalandii
(University of the Western Cape, 1998)Background: The wet coast of southern Africa is subject to coastal upwelling and is characterized by often dense kelp beds that can extend as far as 3 km offshore. Kelp forests create a unique ecosystem. Not only are they ... -
Genetic variation among verticillium dahliae isolates using pathogenicity and aflp analysis
(University of the Western Cape, 1999)Soilborne plant pathogenic fungi have had an important economic and social impact on humans since the evolution of agricultural societies (Stakman, 1959). In South Africa, the soilborne pathogen Verticillium dahliae Kleb, ... -
The effects of clipping and burning on the allocation of total nonstructural carbohydrates and selected mineral nutrients in Imperata cylindrica (L.) Raeuschel
(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 ... -
The experimental cultivation and alginate properties of South African kelps
(University of the Western Cape, 2003)Alginates are used in various industries and the quality of alginates used must be controlled. Alginates used for medical purposes must be of a very high quality. The cost of obtaining high-quality alginate is high and ...
