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; ...
Functional importance of snakes in a strandveld ecosystem
(University of the Western Cape, 2018)
Gaps in our knowledge of the functional roles of snakes within ecosystems limit our ability to
predict the potentially cascading effects their removal from an ecosystem might create.
Extirpation of snake species could ...
Taxonomy and invasive potential of the Cassiinae in southern Africa (Caesalpinioideae, Fabaceae)
(University of the Western Cape, 2019)
Cassiinae is a large subtribe of the tribe Cassieae (Caesalpinioideae) that comprises
ca. 700 species distributed throughout the Americas, Africa, Eurasia and Australia.
The southern African species of Cassiinae (indigenous, ...
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 ...
Characterization of bacterial species in Steinkopf a communal farming area in South Africa: A closer look at pathogenesis
(University of the Western Cape, 2019)
The human population in sub-Saharan Africa has been increasing due to decreases in mortality rates and increases in average human age; in turn increasing poverty and pressure placed on agriculture and agricultural production. ...
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 ...
An Investigation of Benthic Epifauna to Support Classification and Mapping of Outer Shelf Ecosystems in KwaZulu-Natal
(University of the Western Cape, 2017)
Ecosystem classification and mapping are foundational steps for effective ecosystem-based
marine spatial planning, marine ecosystem assessment and integrated ocean management.
The aims of this study were to interrogate and ...
Post-Fire response of botanical and microbial communities in the succulent Karoo
(University of the Western Cape, 2018)
Fire as a form of disturbance is unique in the way it impacts upon the environment, acting like
a herbivore with a ubiquitous appetite. Consuming both dead and living material, converting
complex organic molecules into ...
