How do teachers and learners navigate the terrain of ecology and what are the associated conceptual understandings?
(University of the Western Cape, 2011)This thesis relates the teaching of ecology in schools to the requirements of the National Curriculum Statements, Grades R-9 and Grades 10-12, for Natural and Life Sciences. It examines the conceptual understanding of the ... -
Salt tolerance and modification of wheat salt resistance by plant hormones
(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 ... -
Snake community structure in a heterogeneous fynbos ecosystem
(University of the Western Cape, 2022)Snakes occur in most terrestrial ecosystems, forming an integral part of many ecological communities. A diverse community of snakes in an ecosystem can indicate a complex habitat structure capable of supporting a diverse ... -
Conservation and resource-use relations: Analysis for protected area expansion feasibility in the Western Cape
(University of the Western Cape, 2022)It is assumed that expanding the size and/or number of protected and conservation areas can contribute to more effective conservation, ecosystem services and environmental protection. Expansion is normally a response to ... -
Autecology of the rhombic egg-eater, Dasypeltis scabra
(University of the Western Cape, 2022)Efforts to prevent global losses of biodiversity are hindered by incomplete knowledge of the functional importance of species. In part, this is due to a paucity of information on the basic biology of most species resulting ... -

Heteroscleromorph demosponge taxonomy and diversity of the Amathole region (Eastern Cape, South Africa)
(University of Western Cape, 2022)Sponges are functionally important and ubiquitous components of the global marine benthos. South Africa accounts for roughly 4% of the global marine sponge diversity, comprising 374 described species and seven varieties/forms, ... -
A biogeographic, phylogenetic and taxonomic evaluation of South African orthopteran species (Orthoptera: Pneumoridae)
(University of the Western Cape, 2021)The order Orthoptera contains a wide diversity of species and is the most speciose of the polyneopteran insect lineages. In South Africa, the orthopteran fauna is abundant and diverse, with approximately 88% of all Southern ... -
The Shallow water bryozoans of the West Coast of South Africa
(University of the Western Cape, 2005)The South African biota is characterised by high levels of diversity and endemism. While commercially viable taxa have been well-studied, cryptic organisms such as bryozoans, have been neglected in terms of study. Taxonomic ... -
Studies on the ecology and taxonomy of nematodes of Saldanha Bay, South Africa
(University of the Western Cape, 2013)Few studies of shallow water marine nematodes have been conducted around South Africa, and none from the west coast. Here, I analyse the composition of nematode communities from six stations along a 3 km transect in Saldanha ... -

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 ... -
Characterisation, Isolation, Purification and Toxigenicity ofDiplodiatoxin produced by Stenocarpella maydis in Maize
(University of the Western Cape, 2002)Mycotoxins attract worldwide attention because of the significant economic losses associated with their impact on human health, animal productivity, domestic and international trade. Over 300 mycotoxins have been discovered, ... -
Chemical investigation of some species of Amaryllidaceae from the Greater Cape Region of South Africa as a source of bioactive compounds
(University of the Western Cape, 2020)The family Amaryllidaceae is widely distributed in the southern hemisphere. Members of the family are well known for their content of pharmacologically active alkaloids and represent an important epicentre of Amaryllidac ... -
Native legume species from the Northern Cape province of South Africa and their potential use as forage crops.
(University of Western Cape, 2021)The lack of bioclimatically suitable forage species for livestock production in the water-limited agro-ecological areas of South Africa has resulted in significant feed shortages within these areas during the ongoing drought ... -
Biomonitoring of heavy metals in the Eerste River catchment area
(University of the Western Cape, 2020)The risk of increasing global pollution dictates the need to understand environmental processes and develop innovative ways to monitor pollution levels and address associated problems. In order to address this need, this ... -
Linking biology and sustainable livelihoods to the proposed establishment of community -based Eucheumoid farming in southern Kenya
(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 ... -
Revealing the factors that promote divergence in the Bladder Grasshopper Bullacris unicolor (Orthoptera; Pneumoroidea)
(University of the Western Cape, 2019)Variation in sympatric and allopatric populations is believed to be a precursor to eventual speciation. The dispersion of genes from one gene pool into another is prevented by various processes, including the founder effect, ... -
Species recognition and reproductive isolation in Malawi cichlid fishes, Metriaclima estherae and M. callainos (Teleostei: Cichlidae)
(University of the Western Cape, 2019)Cichlids are one of the most diverse groups of fishes in the world. The highest concentration of cichlids is found in Lake Malawi, where over 1500 species are recorded to occur, which are dominated by the haplochromine ... -
The genus Spongites (Corallinales, Rhodophyta) in South Africa
