The relevance of fog and dew precipitation to succulent plant hydrology in an arid South African ecosystem
(2009)Fog and dew interception and utilization by plant canopies remains one of the least considered aspects of vegetation studies at any scale yet the few studies that have been conducted point to their considerable influence ... -
A Remote sensing change detection study in the arid Richtersveld region of South Africa
(University of the Western Cape, 2007)The Richtersveld falls within the succulent karoo and dester biomes. This studu made use of remote sensing technologies in order to investigate possible vegetation cover changes that have taken place over time, and which ... -
The reproductive physiology of The south african pilchard.
(UWC, 1995)Epipelagic fish species form an integral component of the world's supply of protein. The most abundant of these fish belong to the order Clupeiformes (clupeoids) which include sardine, pilchard, sardinella, sprat, and ... -
Reptile community responses to an avian ecosystem engineer
(University of the Western Cape, 2023)In the Kalahari, sociable weavers (Philetairus socius) build huge, communal nests. Although Kalahari tree skinks (Trachylepis spilogaster) are known to preferentially use trees that host such colonies, the degree to which ... -
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, ... -
Review of South African genera of the family hexabothriidae price, 1942, parasites of chondrichthyan fishes
(2009)The oligonchoinean monogenean family Hexabothriidae Price, 1942 currently consists of approximately 60 valid species, representing 15 genera. Hexabothriids are gill parasites of chondrichthyan fishes (sharks, rays and ... -
Risk analysis and potential implications of exotic Gyrodactylus species on cultured and wild cyprinids in the Western Cape, South Africa
(University of the Western Cape, 2010)The expansion of the South African aquaculture industry coupled with the lack of effective parasite management strategies may potentially have negative effects on both the freshwater biodiversity and economics of the ... -
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. -
The roles of intertidal marine gastropod shells as secondary substrate for macroalgae
(University of the Western Cape, 2014)Primary space within the marine benthos is by far the most limited resource for which all sessile organisms must compete. It only ever becomes available when the organisms occupying it dies or are forced to leave the area. ... -
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 ... -
Seasonal effects on the feeding ecology and habitat of Chersina Angulata in the South Western Cape
(University of the Western Cape, 2008)Nearly one-third of the world’s tortoises live in South Africa, but little is known about their habitat requirements and feeding ecology. Chersina angulata, the angulate tortoise, is endemic to southern Africa, with a ... -
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 ... -
Seaweed extract effects on potato (Solanum Tuberosum 'BP1') and grape (Vitis Vinifera Var. Sultana) Production
(University of the Western Cape, 2017)Field trials were conducted to determine the effects of a locally produced seaweed extract product (Afrikelp LG-1), on the growth parameters and yield of Solanum tuberosum 'BP1'potato crop and Vitis vinifera var. sultana ... -
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 ... -
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 ... -
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 ... -
Spatia-temporal dynamics in land use and habitat fragmentation in the Sandveld, South Africa
(University of the Western Cape, 2010)The Cape Floristic Region (CFR) in South Africa, is one of the world's five Mediterranean hotspots, and is also one of the 34 global biodiversity hotspots. It has rich biological diversity, high level of species endemism ... -
Spatial analysis of open space in the quaternary catchment of the Lourens river
(2011)This thesis looks at aspects relating to vegetated open space in the quaternary catchment of the Lourens River, Cape Town, South Africa in 2005 and at GoogleEarth as a source of imagery for research. The research questions ... -
Spatio-temporal dynamics in land use and habit fragmentation in Sandveld, South Africa
(University of the Western Cape, 2010)This research assessed landuse changes and trends in vegetation cover in the Sandveld, using remote sensing images. Landsat TM satellite images of 1990, 2004 and 2007 were classified using the maximum likelihood classifier ... -
