Diverse genomoviruses representing twenty-nine species identified associated with plants
(Springer Nature, 2020)Genomoviruses (family Genomoviridae) are circular single-stranded DNA viruses that have been mainly identifed through metagenomics studies in a wide variety of samples from various environments. Here, we describe 98 genomes ... -
The diversity and variability of star formation histories in models of galaxy evolution
(2020-07-25)Understanding the variability of galaxy star formation histories (SFHs) across a range of time-scales provides insight into the underlying physical processes that regulate star formation within galaxies. We compile the ... -
Diversity of dsDNA viruses in a South African hot spring assessed by metagenomics and microscopy
(MDPI, 2017)The current view of virus diversity in terrestrial hot springs is limited to a few sampling sites. To expand our current understanding of hot spring viral community diversity, this study aimed to investigate the first ... -
DNA commission of the international society of forensic genetics (IGSF): recommendations on the interpretation of y-str results in forensic analysis
(Elsevier, 2020)Forensic genetic laboratories perform a large amount of STR analyses of the Y chromosome, in particular to analyze the male part of complex DNA mixtures. However, the statistical interpretation of evidence retrieved from ... -
DNA sequencing reveals three new species of Chamberlainium (Corallinales, Rhodophyta) from South Africa, all formerly passing under Spongites yendoi
(De Gruyter Open Ltd, 2021)Three new non-geniculate coralline algal species from South Africa are described that were passing under the misapplied name, Spongites yendoi. Based on plastid encoded DNA sequences from psbA and rbcL markers, these species ... -
Do HIV infection and antiretroviral therapy influence multidrug-resistant tuberculosis treatment outcomes?
(Academic Journals, 2015)The aim of this study was to find out whether human immunodeficiency virus (HIV)-infection and antiretroviral drugs influence multidrug-resistant (MDR)-tuberculosis (TB) treatment outcomes. The study compares MDR-TB treatment ... -
Do lifestyle practices impede male fertility?
(John Wiley & Sons, Inc, 2020)Alongside an increasing prevalence of couple and male infertility, evidence suggests there is a global declining trend in male fertility parameters over the past few decades. This may, at least in part, be explained ... -
Documentation of antipsychotic-related adverse drug reactions: An educational intervention
(AOSIS, 2019)Antipsychotic agents are associated with harmful adverse reactions which impact negatively on patient adherence and clinical management. Accurate and complete documentation of signs and symptoms in the clinical notes is ... -
Does phylogeny have an influence on the date of first description? A comparative study of the world's fishes
(Elsevier, 2020)The process of species description is not random, and understanding the factors that influence when a species is first described (the date of first description, DoFD) allows us to target environments and/or species' traits ... -

(Elsevier, 2020)The process of species description is not random, and understanding the factors that in- fluence when a species is first described (the date of first description, DoFD) allows us to target environments and/or species' ... -
Does seasonality and stochastic cycles affect output growth in Nigeria? Lessons for development planning
(International Foundation for Research and Development (IFRD), 2016)This paper examines the seasonality and stochastic cycle associated with GDP growth in Nigeria using two measures of filter. Our findings include, that the Christiano & Fitzgerald (2003) filter removed low-periodicity ... -
Does the landscape functionality approach provide insight into rangeland conditions in the Tanqua Karoo region, South Africa?
(PeerJ, 2022)The harsh environmental conditions coupled with a long history of overgrazing have altered the ecology of the arid Tanqua Karoo rangelands in South Africa, which necessitates rehabilitation. However, a suitable method ... -
The domestication of the African union model law on medical products regulation: perceived benefits, enabling factors, and challenges
(Frontiers Media, 2023)Introduction: In 2016, the African Union (AU) Model Law on Medical Products Regulation was endorsed by AU Heads of State and Government. The aims of the legislation include harmonisation of regulatory systems, increasing ... -
Don't cut that 'grass'
(Botanical Society of South Africa, 2006)Introduction: Have you ever noticed the abundance of wildflowers on public open spaces during spring in Cape Town? I suppose some Capetonians would be aware of Rondebosch Common and the astonishing botanical diversity ... -
Draft Genome Sequence of Gordonia lacunae BS2T
(American Society for Microbiology, 2017)We report here the draft genome sequence of the soil bacterium Gordonia lacunae BS2T ( DSM 45085T JCM 14873T NRRL B-24551T), isolated from an estuary in Plettenberg Bay, South Africa. Analysis of the draft genome ... -
Draft genome sequence of the putative endophytic bacterium pantoea agglomerans r6, associated with lactuca serriola from South Africa
(American Society for Microbiology, 2021)Here, we present the draft genome sequence (;4.7 Mb) of the endopyhtic bacterium Pantoea agglomerans strain R6, which was isolated from surface-sterilized roots of Lactuca serriola (prickly lettuce) -
DRIFT incorporating an eco-social system network and time series approach into environmental flow assessments
(Taylor & Francis, 2022)DRIFT (Downstream Response to Imposed Flow Transformation) is an interactive, ecological-social process and software package to assist with environmental flow assessments and river management decision-making. It was ... -
Drought and exogenous abscisic acid alter hydrogen peroxide accumulation and diferentially regulate the expression of two maize RD22-like genes
(Nature Research, 2017)Increased biosynthesis of abscisic acid (ABA) occurs in plants in response to water defcit, which is mediated by changes in the levels of reactive oxygen species such as H2O2. Water defcit and ABA induce expression of ... -
Drought and salinity stress alters ROS accumulation, water retention, and osmolyte content in sorghum plants
(Elsevier, 2017)biotic stresses such as drought and salinity are major environmental factors that influence crop productivity worldwide. These adverse conditions induce osmotic stresses in plant cells by decreasing water availability, thus ... -
