The role of grazers and basal sustrate cover in the control of intertidal algal distribution
(University of the Western Cape, 2006)
This study investigated the role of grazing as a possible cause for the upper limit of distribution of algae on a typical South African south coast.
Seasonal movement and activity patterns of the endangered geometric tortoise, psammobates geometricus
(University of the Western Cape, 2005)
Due to the critical status of Psammobates geometricus and the vulnerability of their habitat, there is a need to allocate areas for their protection. The aim of this study was to provide information on the space requirements ...
Growth of juvenile abalone under aquaculture conditions
(University of the Western Cape, 2006)
The aim of this research was, first to test the suitability of different seaweeds and formulated feeds as food for post-weaning juvenile South African abalone and secondly, to test the effects of basket design on the growth ...
Rehabilitation as a method of understanding vegetation change in Paulshoek, Namaqualand
(University of the Western Cape, 2005)
Heavy grazing of rangelands in the succulent karoo has placed the biodiversity of these areas at risk. In Paulshoek, overgrazing has resulted in the removal of much of the palatable vegetation from low lying areas. The ...
Monitoring of heavy metals in the Bottelary River using Typha capensis and Phragmites australis
(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 ...
A global revision of the nongeniculate coralling algal genere Porolithon Foslie (defunct) and Hydrolithon Foslie (Corallinales, Rhodophyta)
(University of the Western Cape, 2005)
The purpose of this thesis was to provide a revision and characterization of the species of nongeniculate coralline algae previously ascribed to the now defunct genus Porolithon; to provide a modern account of selected ...
Species-level phylogenetic reconstruction of the African cycad genus Encephalartos (Zamiaceae)
(University of the Western Cape, 2007)
This thesis explores species-level phylogenetic relationships of the African cycad genus
Encephalartos, which is one of the eleven genera of cycads. The genus is confined to
Africa and comprises approximately 65 species, ...
A yeast 2-hybrid screen to identify and characterize interaction partners of the cancer associated protein Retinoblastoma binding protein 6
(University of the Western Cape, 2009)
Retinoblastoma binding protein 6 (RBBP6) is a 250 kDa protein that is implicated in mRNA processing and ubiquitination functions and has been shown to be highly up-regulated in a number of cancers. In humans and mice, RBBP6 ...
Chytridiomycosis in amphibian populations in the Western Cape, South Africa
(University of the Western Cape, 2002)
There have been many cases reported of amphibian populations declining. These are often due to anthropogenic factors such as habitat destruction and pollution. However, some declines have not had an obvious cause and many ...
The distribution of the desert rain frog ( Breviceps macrops) in South Africa
(University of the Western Cape, 2009)
The desert rain frog (Breviceps macrops) is an arid adapted anuran found on the west coast of southern Africa occurring within the Sandveld of the Succulent Karoo Biome. It is associated with white aeolian sand deposits, ...
