Article
Full-text available
West African Mountains of the Cameroon Volcanic Line harbour two montane-endemic species of laminated-toothed rats (Otomys), which represent the most westerly occurrence of the genus. We explore here through mtDNA sequencing and cranial morphometrics the taxonomic status and phylogenetic relationships of O. burtoni (Mt Cameroon) and O. occidentalis...
Article
We adopted an integrated systematic approach to delimit evolutionary species and describe phylogeographic, morphometric and ecological relationships in Otomys denti (from the Albertine Rift, Southern Rift in Malawi and the northern Eastern Arc Mountains) and Otomys lacustris (from the Southern Rift in Tanzania and Zambia, and the southern Eastern A...
Article
Full-text available
We combined evidence from biogeography, craniodental traits, linear and geometric morphometrics (233 skulls), cytogenetics (karyotypes of 18 individuals) and mitochondrial DNA sequences (44 cytochrome b and 21 12S rRNA sequences) to test species limits within Otomys typus s.l. (Muridae: Murinae: Otomyini), a complex that is patchily distributed acr...
Article
Full-text available
Golden moles (Chrysochloridae) are small, subterranean mammals endemic to sub-Saharan Africa that together with tenrecs constitute one of six orders in Afrotheria. Here we present a comprehensive karyotypic comparison among six species/subspecies of golden moles based on G-banding and chromosome painting. By expanding the species representation to...
Article
Full-text available
Golden moles (Chrysochloridae) are small, subterranean, afrotherian mammals from South Africa and neighboring regions. Of the 21 species now recognized, some (e.g., Chrysochloris asiatica, Amblysomus hottentotus) are relatively common, whereas others (e.g., species of Chrysospalax, Cryptochloris, Neamblysomus) are rare and endangered. Here, we use...
Poster
African swine fever (ASF) virus is maintained in an ancient sylvatic cycle involving long-lived, eyeless soft ticks of the genus Ornithodoros and common warthogs, Phacochoerus africanus. As ASF viruses from the sylvatic cycle are under-represented in reference databases and as infected ticks represent a permanent source of infection, it is importan...
Article
Full-text available
The Greater Maputaland-Pondoland-Albany (GMPA) region of southern Africa was recently designated as a centre of vertebrate endemism. The phylogeography of the vertebrate taxa occupying this region may provide insights into the evolution of faunal endemism in south-eastern Africa. Here we investigate the phylogeographic patterns of an understudied s...

Article
Full-text available
African swine fever virus (ASFV) infection in adult Ornithodoros porcinus (Murry 1877, sensuWalton 1979) ticks collected from warthog burrows in southern and East Africa was assessed using a duplex genomic amplification approach that is informative with respect to the invertebrate host species and infecting sylvatic cycle virus. DNA extracted from...
Article
Full-text available
Chromosomal polytypy, morphological conservatism and absence of data have frustrated the taxonomic revision of two species of southern African-endemic laminate-toothed rats (Otomys irroratus and Otomys saundersiae s.l.). New cytogenetic (G-banding and fluorescence in situ hybridization), DNA sequence [cytochrome b (cyt b) gene] and geometric morpho...

Article
Full-text available
Morphological analyses indicate that horsehose bats in the genus Rhinolophus constitute a monophyletic group which most likely originated in southeastern Asia but which presently inhabits Oriental, Australian, Palaearctic, and Ethiopian zoogeographical provinces. Ten species occur in southern Africa, but it is uncertain which species represent disp...
Article
Full-text available
The number of loci encoding an enzyme system, tissue specificity of gene expression and the degree of gene expression in various tissues are often not mentioned in evolutionary studies, but could indirectly provide evidence of evolutionary relationships. Protein electrophoresis was used to study the distributions and tissue specificity of gene expr...
Article
Full-text available
Diurnal activity budgets of bat-eared foxes Otocyon megalotis in winter (June) at the Postberg Nature Reserve, West Coast National Park, were analysed to determine the influence of environmental factors on their activity. Abiotic factors such as effective temperature, wind speed, cloud cover and rainfall have an effect on prey availability and ther...

The TYRLP programme aims to grow early career academics at UP in the areas of thought leadership, team development, engagement and collaboration, with the intention of enabling them to solve the complex issues that face society. The programme aims to form a community within the University of the like-minded young researchers who possess qualities that will contribute to UP becoming and leading as a research intensive University. (http://www.up.ac.za/en/centre-for-the-advancement-of-scholarship/article/2157959/tuks-young-research-leader-programme) This programme is a new initiative of the University of Pretoria including the Albert Luthuli Centre for Responsible Leadership and the Department of Research and Innovation Support, and in partnership with the Africa Science Leadership Program, KnowInnovation and the Robert Bosch Stiftung. It serves early career researchers in basic and applied science, engineering, social sciences, arts and the humanities. http://www.up.ac.za/en/centre-for-the-advancement-of-scholarship/article/2360490/tyrlp-2016
