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 ...
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 ...
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 ...
Patterns of resource use by livestock during and after drought in a communal rangeland in Namaqualand
(University of the Western Cape, 2006)
Pastoralists in Africa have developed complex mechanisms by which they can alleviate the threat of drought. They practice mobility as one of the strategies to avoid the worst effects of natural stress and disperse grazing ...
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 ...
Adequacy of existing protected areas in conserving biodiversity at global and regional levels in relation to socio-economic conditions
(University of the Western Cape, 2005)
At a meeting of worl leaders at the United Nations Conference on Environment and Development in Rio de Janeiro in 1992, it was recognized that because of the tremendous increase in the size of the global populations (which ...
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 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 ...
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 ...
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 ...
