(University of the Western Cape, 2012)
Southern Africa harbours one-third of the world's Testudinid species, many of which inhabit arid or semi-arid areas, but ecological information on these species is scant. I studied the habitat, morphology and ecology of ...
Sources of heavy metals in vegetables in Cape Town and possible methods of remediation
(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 ...
The ecology of tadpoles in a temporary pond in the Western Cape with comparisons to other habitats
(University of the Western Cape, 2006)
This work centered on the tadpoles in a temporaray pond in the middle of Kenilworth racecourse, Cape Town, South Africa. Trapping was carried out over two wet seasons and five species were found. The racecourse was selected ...
Water regime requirements and possible climate change effects on Fynbos Biome Restionaceae
(University of the Western Cape, 2018)
The Cape Floristic Region (CFR) of southern Africa is one of the world’s most unique

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, ...

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 ...
Coastal marine heatwaves: Understanding extreme forces
(University of the Western Cape, 2017)
Seawater temperature from regional to global scale is central to many measures of biodi-
versity and continues to aid our understanding of the evolution and ecology of biolog-
ical assemblages. Therefore, a clear understanding ...
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 ...
