The Southern Ground Hornbill (SGH – Bucorvus leadbeateri) is one of the largest hornbill species worldwide, known for its complex social structures and breeding behaviours. This bird has been great interest due to declining population disappearance from historic ranges in southern Africa. Despite being focus numerous conservation efforts, with research forming an integral part these initiatives, there still a substantial lack knowledge regarding molecular biology aspects this species. In...
In southern Africa, biotechnology is increasingly important with regard to food security and the development of pharmaceutical industry. Universities are tasked providing relevant capacity through tertiary-level courses meet these needs. However, knowledge practices may be contentious as in issues related genetically modified foods cloning. It also well known that culturally diverse educational situations, students experience epistemological challenges derived from their ontological...
Culex quinquefasciatus Say, 1823 and Anopheles arabiensis Patton, 1905 (Diptera: Culicidae) are often found breeding in the same water sources engage interspecific competition. Although Cx. is known to proliferate a range of polluted environments, ability An. has only been reported relatively recently. The effects pollution insecticide resistance on this competitive interaction unknown. This study examined effect dynamics Three laboratory strains were used study: an susceptible resistant...
Hybridisation is the interbreeding of genetically distinct groups that can lead to introgression – an exchange genetic material between species. conservation concern when alien invasive species involved, as it a loss local adaptations and diversity. significant threat for many dabbling ducks where with closely related Mallard Anas platyrhynchos extremely common. Phenotypic evidence suggests populations in South Africa hybridise indigenous Yellow-billed Duck undulata. The aim this study was...
Chorister Robin-Chat Cossypha dichroa , a South African forest endemic, and Red-capped C. natalensis widely distributed species in woodland, are inferred to hybridise areas of sympatry. DNA was extracted from blood samples (n = 18), 47), two phenotypic hybrids. The mitochondrial cytochrome c oxidase I (COI) gene amplified by PCR sequenced. Phylogenetic analysis performed on the sequence data investigate taxonomic status putative interspecific hybridisation. Phenotypic hybrids grouped with...

Recent research into starling species has revealed the existence of vocal social markers and a link between song temporal structuring organisation. The aim present study was to develop genetic tool for understanding population behaviour (social/parental transmission) mating in Pale-winged Starlings ( Onychognathus nabouroup ), songbird which is found arid areas southern Africa. Using next-generation sequencing, microsatellite comprising six dinucleotides, eighteen trinucleotides twenty-four...
