Documenting the association between a non-geniculate coralline red alga and its molluscan host
(University of the Western Cape, 2010)To further investigate the strength of the association and the relative advantages of the association to both organisms, several manipulation experiments were set up. A cage experiment set up in the shallow subtidal zone ... -
Dynamics and biological implications of the Port St Johns cyclonic lee eddy
(University of the Western Cape, 2016)This project describes the current dynamics of the cyclonic lee eddy off Rame Head, Port St Johns and Waterfall Bluff, and how its physical forcing may influence the biological communities. Three research surveys were ... -
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 ... -
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 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 ... -
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 ... -
Genetic analysis of the Cape Sand Frog, Tomopterna delalandii (Tschudi 1838)
(University of the Western Cape, 2015)Tomopterna delalandii occurs throughout the west coast, Western Cape and south coast of South Africa. This range stretches across three distinct biogeographical assemblages. Based on historical records and the fact that ... -
Granivores as ecosystem regulators of woody plant increasers in semi-arid Savannas of the Lowveld, South Africa
(University of the Western Cape, 2006)In recent years, a global trend of increasing woody vegetation densities in semi-arid savanna habitats has been recorded, commonly described in South Africa as 'bush encroachment'. The shrubs and trees that do this ... -
Growth of juvenile abalone under aquaculture conditions
(University of the Western Cape, 2006)The aim of this research was, first to test the suitability of different seaweeds and formulated feeds as food for post-weaning juvenile South African abalone and secondly, to test the effects of basket design on the growth ... -
Identifying and mapping invasive alien plant individuals and stands from aerial photography and satellite images in the central Hawequa conservation area
(University of the Western Cape, 2012)The Cape Floristic Region, situated at the southern tip of Africa, is one of the world’s most botanically diverse regions. The biodiversity of this region faces various types of threats, which can be divided into three ... -
Impacts and control of alien Proteaceae invasion in the Western Cape Province, South Africa
(University of the Western Cape, 2017)Research focused on ecological impacts and control of invasive alien species (IAS) is gaining attention worldwide. The eradication and control of invasive alien plants (IAP) is essential for the restoration of native plant ... -
Impacts of the invasive reed Arundo donax on biodiversity at the community-ecosystem level
(University of the Western Cape, 2007)Arundo donax is an invasive species that mostly impacts on sensitive riparian ecosystems. Arundo is also invasive in South Africa, though less is known about its ecology, biology, and impacts. Since California and the ... -
Implications of potential biome boundary shifts for small mammal assemblages in the arid zone
(University of the Western Cape, 2019)Desertification deteriorates the landscape functionality of rangelands, affecting the resilience of biome boundaries which have a cascade effect not only in vegetation composition and characteristics but also in animal ... -
In vivo effects of crinum macowanii on the rat cardiovascular system
(University of the Western Cape, 2007)Crinum macowanii (C. macowanii) (Amaryllidacea) as authenticated by Mr. F. Weitz at the Herbarium, University of the Western cape, is widely used a traditional remedy and is thought to have therapeutic value (Fennell and ... -
The inorganic pollution of the Franschhoek River : sources and solutions
(University of the Western Cape, 2011)The aim of the study was to quantify the extent of inorganic chemical pollution of the Franschhoek River and draw relationships between contaminants in water, sediment and plants. The invasive Acacia mearnsii and Salix ...
