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 ...
A survey on external (Ixodidae) and gastrointestinal parasites of small ruminants on an arid communal rangeland in South Africa
(University of Western Cape, 2020)
Parasites pose a major constraint on livestock farming. Its impacts are represented as transmission of disease to humans and economic costs for prevention and treatment as well as loss in terms of; livestock mortality and, ...
Rehabilitation as a method of understanding vegetation change in Paulshoek, Namaqualand
(University of the Western Cape, 2005)
Heavy grazing of rangelands in the succulent karoo has placed the biodiversity of these areas at risk. In Paulshoek, overgrazing has resulted in the removal of much of the palatable vegetation from low lying areas. The ...
Monitoring of heavy metals in the Bottelary River using Typha capensis and Phragmites australis
(University of the Western Cape, 2005)
The aim of this study was to use plants to determine the degree of heavy metal contamination in water and sediments in order to effectively monitor and provide possible recommendation to improve the water quality in the ...
Can bio fortified plants accumulate trace elements essential to the growth and development of humans?
(University of the Western Cape, 2013)
Micronutrient and trace element deficiencies are a problem affecting nearly two billion
people globally. The people affected the most by these deficiencies are those living in poor
and rural communities in the developing ...
Observations on the biology and seasonal variation in feeding of the East Coast redeye round herring (Etrumeus wongratanai) (Clupeiformes), off Scottburgh, KwaZulu-Natal, South Africa
(University of the Western Cape, 2016)
The basic biology and ecology of Etrumeus wongratanai was investigated from samples of fish collected by jigging off Scottburgh, Kwazulu-Natal throughout 2014 and 2015. A total of 516 otoliths, 401 gonads, 140 stomachs and ...
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 ...
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 ...
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 ...
Distributional and dietary overlap between two common squaloid sharks, squalus acutipinnis and squalus bassi, caught as bycatch off the coast of South Africa
(University of Western Cape, 2021)
Squalus acutipinnis and S. bassi may be the most common dogfish species around South Africa, and show overlap in their latitudinal and bathymetric distributions. Even though these sharks are likely endemics, they are also ...
