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 ...
A web-based biodiversity toolkit as a conservation management tool for natural fragments in an urban context
(University of the Western Cape, 2017)
The collection of biological information has a long history, motivated by a variety of reasons and in more recent years is largely being driven for research and academic purposes. As a result biological information is often ...
Intra- and interspecific variability in the distribution patterns and diet of the two most common catsharks caught in demersal trawls off the West and South coasts of South Africa: Evidence for habitat and resource partitioning?
(University of the Western Cape, 2017)
The objective of this thesis was to elucidate intra- and interspecific variability in the
distribution patterns and diet of the two most common demersal catsharks taken as
by-catch by the commercial trawling industry ...
Predicting reptile species distributions and biogeographic patterns within Kruger National Park
(University of the Western Cape, 2018)
Knowledge of global reptile ecology is limited and there remains much to understand in terms of detailed reptile species information, including that of their distributions. In South Africa, despite being one of SANParks ...
Assessing livestock farmers' ecological knowledge and adaptation to climate and environmental change in arid regions of South Africa
(University of the Western Cape, 2017)
Challenges that come with micro-level climate change projections have resulted in
the inadequacy of our understanding of local climatic changes and the appropriate
adaptation strategies. This has resulted in indigenous ...
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 ...
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 ...
An analysis of the fire regime and its effects on post-fire recovery in Namaqualand Granite Renosterveld vegetation
(University of the Western Cape, 2017)
Namaqualand Granite Renosterveld (NGR) is a fire-prone shrubland largely confined to the
Kamiesberg Uplands. More than 20% has been transformed by agricultural activities such as
grazing and dryland cropping. The history ...
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; ...
