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, ...
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 ...
Phylogenetic assessment and historical biogeography of the Psammophis leightoni complex
Stable and accurate taxonomy remains a primary component of conservation. By overlooking
taxonomic disorder, conservation management strategies may ineffectively distribute
resources. The Psammophis leightoni species complex ...
Epiphytic diatom assemblages associated with South African kelps: Ecklonia maxima and Laminaria pallida
(University of Western Cape, 2020)
Kelp forests are dynamic and productive ecosystems which host large biodiversity of sessile
fauna and flora, including diatoms. These microalgae occur at the base of coastal marine
food webs and contribute substantially ...
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 ...
Water regime requirements and possible climate change effects on Fynbos Biome Restionaceae
(University of the Western Cape, 2018)
The Cape Floristic Region (CFR) of southern Africa is one of the world’s most unique
biodiversity hotspots. However, this biodiversity continues to be threatened by habitat loss
due to rapid urbanisation, agriculture and ...
Revealing the factors that promote divergence in the Bladder Grasshopper Bullacris unicolor (Orthoptera; Pneumoroidea)
(University of the Western Cape, 2019)
Variation in sympatric and allopatric populations is believed to be a precursor to eventual speciation. The dispersion of genes from one gene pool into another is prevented by various processes, including the founder effect, ...
Species recognition and reproductive isolation in Malawi cichlid fishes, Metriaclima estherae and M. callainos (Teleostei: Cichlidae)
(University of the Western Cape, 2019)
Cichlids are one of the most diverse groups of fishes in the world. The highest concentration of cichlids is found in Lake Malawi, where over 1500 species are recorded to occur, which are dominated by the haplochromine ...
