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 ...
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 ...
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 ...
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 ...
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 ...
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, ...

(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 ...
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 ...
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 ...
