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 ... -
Amphibian monitoring in Kakamega Forest, Kenya
(2007)Since the late 1970 there has been increased concern of amphibian decline and extinction. Several causes for the worldwide declines have been suggested and include ultraviolet radiation, predation, pollution, climate change, ... -
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 ... -
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 ... -
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 ... -
Species-level phylogenetic reconstruction of the African cycad genus Encephalartos (Zamiaceae)
(University of the Western Cape, 2007)This thesis explores species-level phylogenetic relationships of the African cycad genus Encephalartos, which is one of the eleven genera of cycads. The genus is confined to Africa and comprises approximately 65 species, ... -
Testing the suitability of local seaweeds and formulated feed as a food source for abalone (Haliotis midae Linnaeus) in an Integrated Land-based Aquaculture System
(University of the Western Cape, 2008)The direct methanol fuel cell or DMFC is emerging as a promising alternative energy source for many applications. Developed and developing countries, through research, are fast seeking a cheap and stable supply of energy ... -
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 ... -
Toward best management practices for the growth of the abalone Haliotis midae Linnaeus on a commercial South African abalone farm
(University of the Western Cape, 2008) -
Genetic analysis of resistance to powdery mildew (podosphaeara leucotricha) in apple (Malus x dornestica Borkh.)
(University of the Western Cape, 2008)Apple powdery mildew, caused by Podosphaera leucotricha, is one of the major diseases of the cultivated apple in the Western Cape, causing severe losses in yield and affecting fruit quality. This affects the deciduous ... -
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 ... -
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 ... -
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 ... -
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 ... -
The diet and feeding of the pelagic goby, sufflogobius bibarbatus, off Namibia
(University of the Western Cape, 2009)The general diet of Sufflogobius bibarbatus in the northern Benguela upwelling ecosystem was investigated from gut content analysis in two separate studies. The first study was conducted over two 48 h diel sampling stations ... -
The distribution of the desert rain frog ( Breviceps macrops) in South Africa
(University of the Western Cape, 2009)The desert rain frog (Breviceps macrops) is an arid adapted anuran found on the west coast of southern Africa occurring within the Sandveld of the Succulent Karoo Biome. It is associated with white aeolian sand deposits, ... -

Spatio-temporal dynamics in land use and habit fragmentation in Sandveld, South Africa
(University of the Western Cape, 2010)This research assessed landuse changes and trends in vegetation cover in the Sandveld, using remote sensing images. Landsat TM satellite images of 1990, 2004 and 2007 were classified using the maximum likelihood classifier ... -
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 ... -
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 ...
