African Herald snakes, Crotaphopeltis, show population structure for a widespread generalist but deep genetic divergence for forest specialists
(Wiley, 2020)The African colubrid snake genus Crotaphopeltis currently comprises six species and occurs throughout sub‐Saharan Africa. The most widespread of these, Crotaphopeltis hotamboeia , inhabits most biomes, aside from rainforest ... -
Amphibian chytrid fungus in Africa – realigning hypotheses and the research paradigm
(Wiley, 2020)The amphibian chytrid fungus Batrachochytrium dendrobatidis (Bd), responsible for numerous amphibian declines and extinctions, was previously thought to originate from the African continent. This was based on infected ... -
Batrachochytrium dendrobatidis in amphibians of Cameroon, including first records for caecilians
(Inter Research, 2013)Amphibian chytrid fungus Batrachochytrium dendrobatidis (Bd) has been hypothesised to be an indigenous parasite of African amphibians. In Cameroon, however, previous surveys in one region (in the northwest) failed to ... -
Biological toxicity estimates show involvement of a wider range of toxic compounds in sediments from Durban, South Africa than indicated from instrumental analyses
(Elsevier, 2018)The toxic equivalences (TEQs) of polycyclic aromatic hydrocarbons (PAHs) and polychlorinated biphenyls (PCBs) from sediment of aquatic systems in Durban, South Africa were determined in two ways: 1) TEQs of PAHs and PCBs ... -
Cavinula lilandae (Bacillariophyta), a new diatom species from the Congo Basin, Central Africa
(Taylor & Francis, 2013)Cavinula lilandae, a small new diatom from the Congo Basin in Central Africa, was observed in acid riverine habitats in an almost pristine tropical rain forest. It occurred in a periphytic diatom community dominated by ... -
Characterization of mtDNA variation in a cohort of South African paediatric patients with mitochondrial disease
(Springer Nature, 2012)Mitochondrial disease can be attributed to both mitochondrial and nuclear gene mutations. It has a heterogeneous clinical and biochemical profile, which is compounded by the diversity of the genetic background. Disease-based ... -
Checklist of acanthocephalan parasites of South Africa
(Pensoft, 2018)Twenty-one species of acanthocephalans, representative of thirteen genera from ten families of seven orders and three classes, are included in this updated checklist of acanthocephalans in South Africa. Although South ... -
Complete genome analyses of the first porcine rotavirus group H identified from a South African pig does not provide evidence for recent interspecies transmission events
(Elsevier, 2016)Rotaviruses (RVs) are classified into eight species/groups (RVA–RVH) according to the migration patterns of their 11 genome segments, as well as by serological and molecular properties of Viral Protein 6 (VP6). In 1997 a ... -
Consumers’ knowledge about and attitudes towards lucerne (Medicago sativa l.)
(SAAFECS, 2017)Over the past few years, interest has grown about the health benefits of lucerne (alfalfa), however, little is known about consumers’ attitudes towards consuming this forage legume. Therefore, the aim of this study was to ... -
Current status, hurdles and future prospects of biogas digestion technology in Africa
(Elsevier, 2017)Anaerobic digestion of organic wastes results in the production of biogas and a nutrient-rich digestate. The biogas that is produced through this process consists of methane, carbon dioxide and minute amounts of other ...
