Characterization of bacterial species in Steinkopf a communal farming area in South Africa: A closer look at pathogenesis
Foster, Jodene (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. ... -
Implications of potential biome boundary shifts for small mammal assemblages in the arid zone
Piers, Laetitia (University of the Western Cape, 2019)Desertification deteriorates the landscape functionality of rangelands, affecting the resilience of biome boundaries which have a cascade effect not only in vegetation composition and characteristics but also in animal ... -
Investigating the diet selection and genetic variation of small ruminants in a dryland pastoral system in South Africa
Schroeder, Amy (University of the Western Cape, 2019)Small ruminants found in pastoral dryland systems face many challenges regarding constant environmental and climate changes. These variable environments are home to many pastoralists who use the natural resources to ... -
Investigating the relationship between novel farming practices and zoonotic disease transmission at the wildlife/livestock interface: A case study at a commercial farm and conservancy in Beaufort West, South Africa
Badrodien, Yameen (University of the Western Cape, 2022)In recent years, the intensification of agricultural activities in South Africa, has led to many of the sectors farmers adopting novel farming practices as a means of promoting economic productivity. One such practice, is ... -
Phylogeography and co-evolution of ectoparasitic mites that live on the rodent host species Lemniscomys rosalia (Rodentia: Muridea)
Meissenheimer, Keenan Keith (University of the Western Cape, 2022)Lemniscomys rosalia is a widespread, possibly cryptic species of murid grass mouse. Cytogenetic evidence points towards cryptic speciation in L. rosalia as the eastern African karyotype (2N = 54; FNA = 62) differs from the ... -
Revealing the factors that promote divergence in the Bladder Grasshopper Bullacris unicolor (Orthoptera; Pneumoroidea)
Sathyan, Rekha (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)
Nyalungu, Nonhlanhla Precotia (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 ... -
A survey on external (Ixodidae) and gastrointestinal parasites of small ruminants on an arid communal rangeland in South Africa
Govender, Saloshnie Simone (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, ... -
Towards an unravelling of the taxonomy of Chrysaora (Scyphozoa; Semaeostomeae; Pelagiidae) from around South Africa
Ras, Verena (University of the Western Cape, 2017)Historically, two species of Chrysaora are known from the Benguela Current Ecosystem: C.fulgida (Reynaud 1830) and C. africana (Vanhöffen 1902). However a third morphotype is now seen, which bears a resemblance to both. ...
