Abolishment of morphology‑based taxa and change to binomial species names: 2022 taxonomy update of the ICTV bacterial viruses subcommittee
(Springer, 2023)This article summarises the activities of the Bacterial Viruses Subcommittee of the International Committee on Taxonomy of Viruses for the period of March 2021−March 2022. We provide an overview of the new taxa proposed ... -
Antibacterial activity of rationally designed antimicrobial peptides
(Hindawi, 2020)Many infectious diseases are still prevalent in the world’s populations since no effective treatments are available to eradicate them. e reasons may either be the antibiotic resistance towards the available therapeutic ... -
Application of an in silico approach identifies a genetic locus within ITGB2, and its interactions with HSPG2 and FGF9, to be associated with anterior cruciate ligament rupture risk
(Taylor and Francis Group, 2023)We developed a Biomedical Knowledge Graph model that is phenotype and biological functionaware through integrating knowledge from multiple domains in a Neo4j, graph database. All known human genes were assessed through ... -

Biomass partitioning in an endemic southern African salt marsh species Salicornia tegetaria (Chenopodiaceae)
(Taylor and Francis Group, 2020)The below ground biomass of salt marsh species accounts for more than half of the total plant biomass in salt marsh systems, yet no biomass data exist for salt marsh species in South Africa. ... -
Climate change in coastal waters: Time series properties affecting trend estimation
(AMS, 2016)In South Africa, 129 in situ temperature time series of up to 43 years are used for investigations of the thermal characteristics of coastal seawater. They are collected with handheld thermometers or underwater temperature ... -
The combat-tb workbench: Making powerful Mycobacterium tuberculosis bioinformatics accessible
(American Society for Microbiology, 2022)Whole-genome sequencing (WGS) is a powerful method for detecting drug resistance, genetic diversity, and transmission dynamics of Mycobacterium tuberculosis. Implementation of WGS in public health microbiology laboratories ... -
The contribution of exon-skipping events on chromosome 22 to protein coding diversity
(Cold Spring Harbor Laboratory Press, 2001)Completion of the human genome sequence provides evidence for a gene count with lower bound 30,000–40,000. Significant protein complexity may derive in part from multiple transcript isoforms. Recent EST based studies have ... -
Cross-shelf movement of chrysaora fulgida (scyphozoa; discomedusae) off namibia inferred from stable isotopes (δ15n and δ13c)
(Taylor and Francis Group, 2021)Large and small specimens of two species of metagenic Scyphozoa (true jellyfishes) can be found in nearshore waters off central Namibia throughout the year. Whereas populations of Chrysaora ... -
The diurnal activity budgets of extralimital giraffe (Giraffa camelopardalis giraffa) in the Western Cape Province, South Africa
(Wiley, 2023)Despite being an extralimital species in the region, South African giraffes (Giraffa camelopardalis giraffa, Schreber 1784) are continuously being introduced into the Albany Thicket Biome of the Western Cape Province of ... -
The effect of anthropogenic noise and weather conditions on male calls in the bladder grasshopper Bullacris unicolor
(Taylor and Francis Group, 2021)Acoustic communication in animals relies upon specificcontextsandenvironments for effective signal transmission. Increasing anthropo-genic noise pollution and different weather conditions can disruptacoustic communication. ... -
Environmental response and ph tolerance of induced co2 in ulva rigida c.agardh, 1823(Chlorophyta) under controlled conditions
(PAS FORUM, 2022)The increase in integrated multitrophic aquaculture (IMTA), where seaweed (particularly Ulva rigidaC.Agardh, 1823) is used as a feedstock and a wastewater scrubber in South African IMTA systems, has necessitated research ... -
Establishing an economically and biologically sustainable and viable inland fisheries sector in South Africa – pitfalls of path dependence
(Water Research Commission, 2022)Small-scale fisheries play a significant role in livelihoods and food and nutrition security for millions of people around the world. However, these benefits are under threat, especially in developing countries such as ... -
Exosomes form tunneling nanotubes (TUNTs) in the blood-brain barrier: A nano-anatomical perspective of barrier genesis
(Frontiers Media, 2022)The blood-brain barrier (BBB) is a robust interface between the blood and the central nervous system. Barrier type endothelium is able to limit paracellular (PC) movement, relegating molecular flux to the transendothel ... -
Genetic and morphological variation of the lanternfish lampanyctodes hectoris (myctophiformes: myctophidae) off Southern Africa
(Taylor and Francis Group, 2001)Genetic and morphological variation within the southern African population of Lampanyctodes hectoris was analysed. A total of 15 enzymes, encoding 22 isozyme loci, was examined (n = 327); seven were polymorphic. The ... -
Giants and titans: First records of the invasive acorn barnacles Megabalanus tintinnabulum (Linnaeus, 1758) and Megabalanus coccopoma (Darwin, 1854) on intertidal rocky shores of South Africa
(Regional Euro-Asian Biological Invasions Centre (REABIC), 2022)During intertidal rocky shore surveys on the east coast of South Africa in 2018, the non-indigenous giant purple barnacle Megabalanus tintinnabulum (Linnaeus, 1758), a well-known fouling and globally-invasive species, ... -
The interaction of text and visual in specialized dictionary definitions
(John Benjamins Publishing, 2013)Although visuals have been co-deployed with text in specialized dictionaries as far back as the European Renaissance, the interaction of both representational modalities is relatively under-researched. As a consequence, ... -
Intercolony variation in reproductive skipping in the African penguin
