Investigating phytoplankton fluctuations and drum filter effectiveness on an abalone farm in Hermanus, South Africa.
(University of the Western Cape, 2021)Aquaculture is a growing industry in South Africa, with the production of abalone, Haliotis midae, at the forefront. The Western Cape Province hosts 12 of the 18 abalone farms in South Africa, with a concentration of ... -
The effect of exogenous growth regulators on salinity tolerance in Erucastrum strigosum
(University of the Western Cape, 2003)Randomized block experiments were conducted to examine the putative amelioratory effects of kinetin or gibberellic acid at concentrations (0, 4, 12.5, 40, and 125 μM) in Erucastrum strigosum plants subjected to a salinity ... -
Quantifying competition in two co-occurring southern African psammophiinae snakes: Psammophis crucifer and psammophylax r. Rhombeatus
(University of Western Cape, 2020)Studies on snake competitive interactions have relatively been well documented globally, however, those examples tend to be dominated by non-African examples. Africa has a large and spectacular reptile diversity and yet ... -
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, ... -
Examining intra- and interspecific variability in the diet and carbon and nitrogen stable isotope ratios of kingklip and monkfish caught off the West and South coasts of South Africa
(University of Western Cape, 2020)Kingklip (Genypterus capensis) and monkfish (Lophius vomerinus) and are ecologically and economically important demersal fish species that are found along both the eastern and western parts of southern Africa’s coastline. ... -
Intra- and inter-population variation in the bladder grasshopper Bullacris unicolor
(University of the Western Cape, 2014)Although the processes that promote biodiversity and speciation remain poorly understood, ecological factors are thought to be one of the causal agents responsible for promoting variation. Bladder grasshoppers (Orthoptera; ... -
Tonic immobility in two species of Southern African catsharks
(University of Western Cape, 2020)Tonic immobility (TI) can be defined as an unlearned behavioural response described by a physical state of immobility. This behaviour can last from a few seconds up to several hours. Tonic immobility in sharks has not been ... -
Ecology and diet of the caracal (Caracal caracal) on lethal and non-lethal control farms in the Karoo
(University of the Western Cape, 2020)Human-wildlife conflict is an ongoing issue worldwide. Within South Africa, human-carnivore conflict (HCC) as a result of carnivore depredation on small-livestock causes large-scale losses, and promotes the use of predator ... -

Developing fixed-point photography methodologies for assessing post-fire mountain fynbos vegetation succession as a tool for biodiversity management
(University of Western Cape, 2020)Areas of high biodiversity and complex species assemblages are often difficult to manage and to set up meaningful monitoring and evaluations programmes. Mountain Fynbos is such an ecosystem and in the Cape of Good Hope ... -
A systematic conservation plan for threatened freshwater wetlanddependent waterbirds across South Africa
(University of Western Cape, 2020)Freshwater ecosystems are valuable to all components of biodiversity communities. Globally, these ecosystems are threatened by human activity and as a consequence, many vertebrates, including waterbirds, have become ... -
Systematics of subtribes Athanasiinae and Phymasperminae (Anthemideae, Asteraceae)
(University of the Western Cape, 2020)The tribe Anthemideae is a large tribe of the family Asteraceae comprising 111 genera and 1 800 species distributed in Africa, Europe, Asia, and the Northern temperate region, with southern Africa as one of its main centers ... -

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 ... -
Genetic and morphological comparisons within the orthopteran family Pneumoridae
(University of the Western Cape, 2019)Bladder grasshoppers belong to the order Orthoptera, ancient family Pneumoridae and Superfamily Pneumoroidea. This small group of grasshoppers are sound producing, nocturnal, herbivorous grasshoppers endemic to the coastal ... -
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 ... -
Detecting patterns of upwelling variability in Eastern Boundary Upwelling Systems with special emphasis on the Benguela region
(University of the Western Cape, 2020)Coastal upwelling is one of the most important oceanographic processes relating to ecosystem function at local and global spatial scales. To better understand how changes in upwelling trends may occur in the face of ongoing ... -
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 ... -
