Lichen thermal sensitivities, moisture interception and elemental accumulation in an arid South African ecosystem
(University of the Western Cape, 2010)Elevated temperatures accompanying climate warming are expected to have adverse effects on sensitive lichen species. This premise was examined by measuring the sensitivity of different lichen species to elevated temperatures ... -
Long-term vegetation monitoring – a 33 year record from table mountain
(2013)Nearly 40 years ago McLachlan and Moll highlighted the need for a well-defined path system on the Western Table of Table Mountain in the immediate vicinity of the Upper Cable Station (UCS). At that time the numbers of ... -
Medicinal plant use in the Dwarsrivier Valley, Stellenbosch
(University of the Western Cape, 2013)Plants have been used as medicine since antiquity. Passed on by word of mouth through the generations, this oral tradition is at risk of becoming extinct due to westernization and lack of documentation. The community in ... -
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 ... -
Monitoring water quality with riparian trees along the Berg River, Western Cape
(University of the Western Cape, 2012)Heavy metals and nutrients have long been regarded as pollutants to freshwater ecosystems. These elements have a detrimental effect on plants, animals and the water quality of rivers in South Africa. The Berg River flows ... -
Observations on the biology and seasonal variation in feeding of the East Coast redeye round herring (Etrumeus wongratanai) (Clupeiformes), off Scottburgh, KwaZulu-Natal, South Africa
(University of the Western Cape, 2016)The basic biology and ecology of Etrumeus wongratanai was investigated from samples of fish collected by jigging off Scottburgh, Kwazulu-Natal throughout 2014 and 2015. A total of 516 otoliths, 401 gonads, 140 stomachs and ... -
Patterns of resource use by livestock during and after drought in a communal rangeland in Namaqualand
(University of the Western Cape, 2006)Pastoralists in Africa have developed complex mechanisms by which they can alleviate the threat of drought. They practice mobility as one of the strategies to avoid the worst effects of natural stress and disperse grazing ... -
Phylogenetic assessment and historical biogeography of the Psammophis leightoni complex
Stable and accurate taxonomy remains a primary component of conservation. By overlooking taxonomic disorder, conservation management strategies may ineffectively distribute resources. The Psammophis leightoni species complex ... -
Post-Fire response of botanical and microbial communities in the succulent Karoo
(University of the Western Cape, 2018)Fire as a form of disturbance is unique in the way it impacts upon the environment, acting like a herbivore with a ubiquitous appetite. Consuming both dead and living material, converting complex organic molecules into ... -
Predicting reptile species distributions and biogeographic patterns within Kruger National Park
(University of the Western Cape, 2018)Knowledge of global reptile ecology is limited and there remains much to understand in terms of detailed reptile species information, including that of their distributions. In South Africa, despite being one of SANParks ... -
Re-descriptions of some Southern african Scyphozoa: out with the old and in with the new
(University of the Western Cape, 2009)Two species of Chrysaora are described from the northern Benguela ecosystem: C. fulgida and C. africana. These species can be diagnosed by a combination of morphological features including lappet and tentacle number, shape ... -
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 ... -
The relationship between sediment composition and infaunal polychaete communities along the southern coast of Namibia
(University of the Western Cape, 2005)This study examined the relationship between sediment structure and infaunal polychaete communities off the southern coast of Namibia from two separate sets of data, and a total of ninety-two samples. It also examined ... -
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 ... -
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. -
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 ... -
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 ...
