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 biodiversity hotspots. However, this biodiversity continues to be threatened by habitat loss due to rapid urbanisation, agriculture and ... -
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 ... -
Patterns in diversity, abundance, distribution and community structure of epi-pelagic copepods in the south-western Indian Ocean
(University of the Western Cape, 2016)The primary objective of this study was to investigate patterns in diversity, abundance, distribution and community structure of epi-pelagic copepods across the South West Indian Ocean Ridge (SWIOR). A survey was conducted ... -
Diversity and Zoogeography of South African Bryozoa
(University of the Western Cape, 2017)The taxonomic history of South African bryozoans is fragmented and outdated, with the majority of published works in the 20th Century. Sampling gaps exist in deep-sea regions and parts of the coastline, while existing ... -
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 ... -
Systematics, diversification and ecology of the Conophytum-clade (Ruschieae; Aizoaceae)
(University of the Western Cape, 2016)The Ruschieae is the most diverse and speciose tribe within the large subfamily Ruschioideae (Aizoaceae), with approximately 71 genera and a distribution centred in the arid parts of the Greater Cape Floristic Region (GCFR) ... -
Using Ulva (Chlorophyta) for the production of biomethane and mitigation against coastal acidification
(University of the Western Cape, 2016)In South Africa the green macroalga Ulva armoricana is the main species of macroalgae cultured. The species is currently the largest aquaculture (2884.61 tonnes) product by weight with a corresponding capacity for biogas ... -
Assisted flocculation of Chlorella Sorokiniana by co-culture with filamentous fungi
(University of the Western Cape, 2015)Biofuel production from microalgae is currently not economically competitive with fossil fuels due to high operational costs. A sustainable system needs to be developed which considers cultivation, harvesting and conversion ... -
Systematics of the non-geniculate coralline red algae from the South African south coast
(University of the Western Cape, 2015)The aim of this study was to document the intertidal and shallow subtidal species of non-geniculate coralline red algae from the South Africa south coast. The main emphasis of the study are encompassed in four research ... -
An analysis of primary and secondary production in lake Kariba in a changing climate
(University of Western Cape, 2011)Analysis of temperature, rainfall and evaporation records over a 44-year period spanning the years 1964 to 2008 indicates changes in the climate around Lake Kariba. Mean annual temperatures have increased by approximately ... -
Impacts of degradation on critically endangered Oudtshoorn Gannaveld
(2010)In the Succulent Karoo biome of South Africa vegetation degradation by overgrazing is a recognized threat to biodiversity. In the eastern Little Karoo region of the Western Cape Province, ostrich farming has degraded large ... -
Biochemical investigation of anti-cancer activity of Tulbaghia violacea
(UWC, 2012)Natural products have been a source of many pharmaceutical drugs and a number of drugs that are currently used in the treatment of cancer are derivatives of compounds originally isolated from natural products. There is ... -
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 ... -
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 ... -
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 ... -
Ecology and morphology of the Kalahari tent tortoise, Psammobates oculifer, in a semi-arid environment
(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 ... -
