Biological crusts of serpentine and non-serpentine soils from the Barberton Greenstone Belt of South Africa
Venter, Arthurita; Siebert, Stefan; Rajakaruna, Nishanta; Barnard, Sandra; Levanets, Anatoliy; Peterson, Bianca; Sanko, Tomasz (Springer, 2017)Climate and geography can influence biological soil crust (BSC) community composition, but local heterogeneity in variables such as soil characteristics or microclimate gradients can also impact cryptogamic diversity. Heavy ... -
A case study to determine the efficacy of ozonation in purification processes
Morrison, S.; Venter, A.; Barnard, S. (South African Water Research Commission, 2012)The aim of this study was to determine the efficacy of ozone in water purification processes at the Midvaal Water Company, which uses the hypertrophic Middle Vaal River for source water. It was found that pre- and ... -
Cyanobacteria and algae of gold mine tailings in the North-West Province of South Africa
Orlekowsky, Tanya; Venter, Arthurita; Van Wyk, Fanus; Levanets, Anatoliy (Borntraeger Science Publishers, 2013)Cryptogamic crusts are important components in arid and semiarid lands and could play a vital role in the rehabilitation of mine tailings. The aim of this study was therefore to investigate the occurrence of cyanobacteria ... -
Die klassifikasie van 'n sianoprokarioot deur van ligmikroskopie, transmissie elektronmikroskopie en molekul?re tegnieke gebruik te maak
Levanets, A.; Venter, Arthurita; Labuschange, L.; Wescott, M.; Du Plessis, Sandra (OpenJournals Publishing, 2009) -
Growth of soil algae and cyanobacteria on gold mine tailings material
Seiderer, Tanya; Venter, Arthurita; Van Wyk, Fanus; Levanets, Anatoliy; Jordaan, Anine (ASSAf, 2017)The goal of revegetation of gold mine tailings storage facilities is to reduce aeolian pollution, nutrient leaching and erosion caused by exposure to wind and water. The establishment of biological soil crusts may prove ... -
Overview of the influences of mining-related pollution on the water quality of the Mooi River system's reservoirs, using basic statistical analyses and self organised mapping
Barnard, S.; Venter, A.; Van Ginkel, C.E. (South African Water Research Commission, 2013)The Mooi River catchment, in particular the Wonderfonteinspruit (WFS), has been the subject of a large number of studies regarding significant pollution sources, generally attributed to mining in the area. However, very ... -
Photosynthetic differences between Microcysistis aeruginosa and Oscillatoria simplicissima in relation to species succession in the Vaal River, South Africa
Strauss, Abram Johannes; Venter, Arthurita; Bezuidenhout, Johannes; Van Heerden, Riekert; Du Plessis, Sandra (Taylor & Francis, 2009) -
Planktonic algae and cyanoprokaryotes as indicators of ecosystem quality in the Mooi River system in the North-West Province, South Africa
Venter, A.; Barnard, S.; Dickinson, M.A.; Janse van Vuuren, S.; Levanets, A.; Taylor, J.C. (South African Water Research Commission, 2013)An ecologically healthy Mooi River system is important for maintaining the quality of potable water of Potchefstroom and surrounding areas. However, this system is under constant threat from anthropogenic pollution arising ... -
A preliminary survey of the diversity of soil algae and cyanoprokaryotes on mafic and ultramafic substrates in South Africa
Venter, Arthurita; Levanets, Anatoliy; Rajakaruna, Nishanta; Siebert, Stefan (CSIRO Publishing, 2015)Despite a large body of work on the serpentine-substrate effect on vascular plants, little work has been undertaken to describe algal communities found on serpentine soils derived from peridotite and other ultramafic rocks. ... -
Re-identification of "Oscillatoria simplicissima" isolated from the Vaal River, South Africa, as Planktothrix pseudagardhii
Du Plessis, Sandra; Conradie, Karin Ronel; Venter, Arthurita (Elsevier B.V., 2008)
