Ecklonia maxima kelp forests along a thermal gradient: community composition and recovery from disturbance
(University of the Western Cape, 2017)Climate change will influence species distributions, survival and ecosystem functioning, mostly through changes in sea surface temperatures and storm disturbance. Species are expected to shift poleward in response to ocean ... -
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 ... -

The effect of copper on the growth, development and chemical composition of some dryland wheat cultivars
(University of the Western Cape, 2005)Heavy metal accumulation in arable land as a result of mining activities, pesticides and fertilisers has become a global concern. Steinkopf and Concordia in the Northern Cape are well-known for subsistence farming, but ... -
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 ... -
The effect of maternal nicotine exposure on the quantity and quality of neonatal rat lung connective tissue
(University of the Western Cape, 1994)The infants of smoking mothers (compared to non-smoking mothers) have been shown to have a lower birth mass, a lower brain mass, an increased perinatal mortality rate as well as a predisposition to respiratory abnormalities ... -
The effects of anthropogenic disturbance upon African penguin colonies
(University of Western Cape, 2020)African penguin (Spheniscus demersus) mainland colonies are a popular tourist attraction in the Western Cape of South Africa. The African penguin population is in decline and the species is listed as endangered on the ... -
The Effects of Cadmium and Lead on Phaseolus vulgaris
(University of the Western Cape, 2012)The demand for better quality produce by consumers is on the increase, as higher heavy metal concentrations pose a problem in agriculture. They result in decreased yield and unsuitable food for human consumption. This ... -
The effects of differences in feeding regime and of export simulations on the growth of the abalone Haliotis midae Linnaeus
(University of the Western Cape, 2008)Beach-cast kelp (the most widely used feed for commercially grown South African abalone) is plentiful during winter months when periodic storms cause kelp to wash ashore. During summer, however, this resource is not always ... -
The effects of real exchange rate misalignment on exports in South Africa.
(University of Western Cape, 2020)The purpose of this study was to evaluate econometrically the effects of real exchange rate misalignment on South African exports between the period 1994 and 2015 using quarterly time-series data. Cointegration tests were ... -
Effects of season and cohort on the haematology of the geometric tortoise Psammobates geometricus.
(University of the Western Cape, 2012)The geometric tortoise is one of the world‟s rarest terrestrial tortoises and is endemic to the Southwestern Cape, South Africa. There has been cause for conservation concern for Psammobates geometricus, yet as is common ... -
Empirical and model derived respiration responses to climate in different soils of an arid South African ecosystem
(2009)This study examined the magnitude of soil CO2 efflux in an arid South African ecosystem, the flux responses as well as those of key limiting nutrients to soil temperature increases and moisture reductions consistent with ... -
Epiphytic diatom assemblages associated with South African kelps: Ecklonia maxima and Laminaria pallida
(University of Western Cape, 2020)Kelp forests are dynamic and productive ecosystems which host large biodiversity of sessile fauna and flora, including diatoms. These microalgae occur at the base of coastal marine food webs and contribute substantially ... -
The evaluation and development of diagnostic tools for the detection of ichthyophonus hoferi in fish host tissue samples
(University of the Western Cape, 2019)Ichthyophonus hoferi is a highly pathogenic histozoic parasite that has low host specificity capable of producing mass mortalities of epizootic proportions in marine commercial fish populations. Currently in Southern Africa, ... -
Evaluation of quantitative motility and zona pellucida binding of human spermatozoa in an assisted reproductive programme
(University of the Western Cape, 1994)Male factor disorders affect more than 30% of infertile couples. Thus, it has become important to perform a andrological consultation and a basic semen evaluation in all male partners of couples consulting for infertility. ... -
Evaluation of the level of compliance of Veterinary medicine package inserts with Regulatory authority guidelines
(University of the Western Cape, 2021)Background: Veterinary medicines play an imperative role in the diagnosis, prevention and treatment of animal diseases. Many veterinary stock remedies in South Africa are available to the public without the intervention ... -
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. ... -
Food resources available to juvenile fish (particularly rhabdosargus holubi) in seagrass beds of the swartkops etuary
(University of the Western Cape, 2023)Estuarine habitats are critical nursery areas for many species of marine fishes during their early life stages in terms of food availability and structural complexity, which increases survival and growth rates. The Cape ... -
Foraging ecology of Naja nivea and Dispholidus typus
(University of the Western Cape, 2019)It is widely reported that snakes can be major predators of avian nests, but the use of a single avian prey type by competing species has rarely been examined. This study aimed to investigate predation of a single food ... -
Functional importance of snakes in a strandveld ecosystem
(University of the Western Cape, 2018)Gaps in our knowledge of the functional roles of snakes within ecosystems limit our ability to predict the potentially cascading effects their removal from an ecosystem might create. Extirpation of snake species could ...
