Distribution patterns of Acidobacteriota in different fynbos soils
(Public Library of Science, 2021-03-22)Abstract The Acidobacteriota is ubiquitous and is considered as one of the major bacterial phyla in soils. The current taxonomic classifications of this phylum are divided into 15 class-level subdivisions (SDs), with ... -
Influence of large artificial porosity on bending behaviour of TI6AL4V ELI additively manufactured specimens subjected to typical loads during mastication
(Southern African Institute for Industrial Engineering, 2020)Effective quality control of implants made using additive manufacturing is an important task for suppliers to comply fully with existing regulations and certifications. To study the influence of porosity on the mechanical ... -
4-Benzyloxylonchocarpin and muracatanes A-C from Ranunculus muricatus L. and their biological effects
(MDPI, 2020-11-17)ENGLISH ABSTRACT: Ranunculus muricatus L. is a spiny fruit buttercup that is used in various traditional medicinal systems. In the current investigation of R. muricatus, the new chalcone 4-benzyloxylonchocarpin (1), the ... -
Trait positions for elevated invasiveness in adaptive ecological networks
(Springer, 2021)Our ability to predict the outcome of invasion declines rapidly as non-native species progress through intertwined ecological barriers to establish and spread in recipient ecosystems. This is largely due to the lack of ... -
Profiling the production of antimicrobial secondary metabolites by xenorhabdus khoisanae J194 under different culturing conditions
(Frontiers Media, 2020-03-30)Species from the genus Xenorhabdus, endosymbiotic bacteria of Steinernema nematodes, produce several antibacterial and antifungal compounds, some of which are anti-parasitic. In this study, we report on the effect growth ... -

(MDPI, 2020-12-07)The sponge Leucetta chagosensisDendy (1913) has a wide distribution throughout the Indo-Pacific (IP) region, with previous studies focussing primarily on the western Pacific Ocean. To increase our knowledge of the spatial ... -
Tick fauna and associated Rickettsia, Theileria, and Babesia spp. in domestic animals in Sudan (North Kordofan and Kassala States)
(MDPI, 2020-12-11)Ticks and tick-borne diseases (TBDs) have a major economic impact on animal production worldwide. In the present study, 2410 ticks were collected from January to August 2017 from livestock and other domestic animals in ... -
Manual sampling and video observations : an integrated approach to studying flower-visiting arthropods in high-mountain environments
(MDPI, 2020-12-11)Despite the rising interest in biotic interactions in mountain ecosystems, little is known about high-altitude flower-visiting arthropods. In particular, since the research in these environment can be limited or undermined ... -
A review of fire management practices in African savanna-protected areas
(AOSIS, 2021)The level of understanding of the ecological effects of fires has improved over the past century, but comprehensive information on the practical application of fire remains restricted to a few well-studied areas, and ... -
Characterisation of Metarhizium majus (Hypocreales : Clavicipitaceae) isolated from the Western Cape Province, South Africa
(Public Library of SciencePublisher's version, 2021-03-19)Entomopathogenic fungi (EPF) are important soil-dwelling entomopathogens, which can be used as biological control agents against pest insects. EPF are capable of causing lethal epizootics in pest insect populations in ... -
Urban plant invasions: how to classify, prioritize and manage invasive alien plants; Cape Town as a case study
(Stellenbosch : Stellenbosch University, 2021-03)ENGLISH ABSTRACT: Urban areas are considered hotspots for invasions, with human activity being a major source of introduction and causing the dispersal of invasive alien plant species (IAPs). This makes natural and semi ... -
