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 ...
Intra- and inter-population variation in the bladder grasshopper Bullacris unicolor
(University of the Western Cape, 2014)
Although the processes that promote biodiversity and speciation remain poorly understood, ecological factors are thought to be one of the causal agents responsible for promoting variation. Bladder grasshoppers (Orthoptera; ...
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 ...
Risk analysis and potential implications of exotic Gyrodactylus species on cultured and wild cyprinids in the Western Cape, South Africa
(University of the Western Cape, 2010)
The expansion of the South African aquaculture industry coupled with the lack of effective parasite management strategies may potentially have negative effects on both the freshwater biodiversity and economics of the ...
Medicinal plant use in the Dwarsrivier Valley, Stellenbosch
(University of the Western Cape, 2013)
Plants have been used as medicine since antiquity. Passed on by word of mouth through the generations, this oral tradition is at risk of becoming extinct due to westernization and lack of documentation. The community in ...
Long-term vegetation monitoring – a 33 year record from table mountain
(2013)
Nearly 40 years ago McLachlan and Moll highlighted the need for a well-defined path system on the Western Table of Table Mountain in the immediate vicinity of the Upper Cable Station (UCS). At that time the numbers of ...
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 ...
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 ...
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 ...
