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 ... -
Genome sequence of an alkaliphilus species isolated from historically contaminated sediments of the gulf of Naples (Mediterranean Sea)
(American Society for Microbiology, 2021)Here, we report the draft genome sequence of a metagenome-assembled genome (MAG) of a new Alkaliphilus bacterium, NP8, of the Clostridiaceae family. This bacterium was isolated from polluted sediment collected from an ... -
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, ... -
A global infrageneric classification system for the genus Crotalaria (Leguminosae) based on molecular and morphological evidence
(Botanischer Garten und Botanisches Museum, 2013)Crotalaria is a large genus of 702 species with its centre of diversity in tropical Africa and Madagascar and secondary radiations in other parts of the world. The current infrageneric classification system is based on ... -
Groundwater discharges to aquatic ecosystems associated with the Table Mountain Group (TMG) aquifer: a conceptual model
(Water Research Commission, 2008)This paper reports on a conceptual model that was developed to describe the different groundwater discharge ‘types’ from the Table Mountain Group (TMG) aquifer, that contributes to the different components of the flow ... -
Growth of market-size abalone (Haliotis midae) fed kelp (Ecklonia maxima) versus a low-protein commercial feed
(Taylor & Francis, 2008)The growth of grow-out abalone fed on kelp, with ca. 10 % dry weight protein content, was compared with that of those fed a new ,ca. 26 % protein, commercial feed in a flow-through system on a South African west coast ... -
The growth of post-weaning abalone (Haliotis midae Linnaeus) fed commercially available formulated feeds supplemented with fresh wild seaweed
(National Inquiry Services Centre (NISC) and Taylor & Francis, 2008)The effect of five formulated feeds, supplemented with fresh wild seaweed on the growth of post-weaning juvenile abalone (6 - 20 mm shell length), Haliotis midae Linnaeus was investigated by means of a growth trial at a ... -
Gyrodactylus molweni sp. n. (Monogenea: Gyrodactylidae) from Chelon richardsonii (Smith, 1846) (Mugilidae) from Table Bay, South Africa
(Elsevier, 2021)Gyrodactylus molweni sp. n. is described from the body surface and fins of the South African mullet, Chelon richardsonii (Smith, 1846) collected from Table Bay Harbour, Cape Town and is compared to five other Gyrodactylus ... -
Happy Feet in a Hostile World? The Future of Penguins Depends on Proactive Management of Current and Expected Threats
(2019)Penguins face a wide range of threats. Most observed population changes have been negative and have happened over the last 60 years. Today, populations of 11 penguin species are decreasing. Here we present a review that ... -
Hatch traits of artificially incubated ostrich eggs as affected by setting position, angle of rotation and season
(AJOL, 2020)High levels of hatching failure in artificially incubated ostrich eggs cause considerable loss of income for the industry. In the 2015 - 2016 breeding seasons, between 846 and 1 549 egg records were used to determine the ... -
Heavy metals in the irrigation water, soils and vegetables in the Philippi horticultural area in the Western Cape Province of South Africa
(Springer Verlag, 2014)The aims of this study were to investigate the extent of heavy metal contamination in the Philippi horticultural area in the Western Cape Province, South Africa. Concentrations of Cd, Cr, Cu, Mn, Ni, Pb and Zn were ... -
Heydrichia cerasina sp. nov. (Sporolithales, Corallinophycidae, Rhodophyta) from the southernmost tip of Africa. Phycologia, 51(1): 11- 21
(International Phycological Society, 2012)A new species of Heydrichia (Sporolithales), H. cerasina sp. nov., is described, found only on pebbles in the low intertidal zone along a 10 km stretch of the South African south coast from Cape Agulhas to Struisbaai. The ... -
High-depth African genomes inform human migration and health
(Choudhury, A. et al. (2021). Author correction: High-depth African genomes inform human migration and health (nature, (2020), 586, 7831, (741-748), 10.1038/s41586-020-2859-7). Nature, 592(7856), E26. doi:10.1038/s41586-021-03286-9, 2021)The African continent is regarded as the cradle of modern humans and African genomes contain more genetic variation than those from any other continent, yet only a fraction of the genetic diversity among African individuals ... -
Hitting the right target: taxonomic challenges for, and of, plant invasions
(Oxford University Press, 2013)This paper explores how a lack of taxonomic expertise, and by implication a dearth of taxonomic products such as identification tools, has hindered progress in understanding andmanaging biological invasions. It also ... -
How many species of angulate tortoises occur in Southern Africa? (Testudines: Testudinidae: Chersina)
(Wiley-Blackwell, 2020)Using range-wide sampling and 1,143 bp of mtDNA (cytochrome b gene) and 14 microsatellite loci, we examined genetic differentiation in the widely distributed Southern African angulate tortoise (Chersina angulata). We found ... -
How much leaf area do insects eat? A data set of insect herbivory sampled globally with a standardized protocol
