Ezeokoli, Obinna T.; Adeleke, Rasheed A.; Maboeta, Mark S.; Bezuidenhout, Cornelius C.; Nwangburuka, Cyril C. (Taylor & Francis, 2019)The symbioses between arbuscular mycorrhizal (AM) fungi and plant roots is essential for nutrient uptake and growth of most vascular plants. Soil condition and management influence the density and viability of arbuscular ... -
Earthworm (Eisenia Fetida) bioassay to assess the possible effects of platinum tailings disposal facilities on the environment along a gradient
Maboeta, M.S.; Van Rensburg, L.; Jansen van Rensburg, P.J. (ALÖKI Applied Ecological Research and Forensic Institute Ltd., 2008)Platinum mines produce large amounts of inorganic tailings containing high levels of metals which are disposed of on tailings disposal facilities (TDFs) and there is no information available on their possible effects on ... -
Ecotoxicity of mine tailings: unrehabilitated versus rehabilitated
Maboeta, M.S.; Oladipo, O.G.; Botha, S.M. (Springer, 2018)Earthworms are bioindicators of soil pollution. The ecotoxicity of tailings from selected gold mines in South Africa was investigated utilizing Eisenia andrei bioassays and biomarkers. Samples were obtained from unrehabilitated, ... -
Ecotoxicological assessment of chemical fumigants utilising an earthworm (Eisenia andrei) bioassay and soil microbial communities
Fouché, Tanya C.; Claassens, Sarina; Maboeta, Mark S. (Springer, 2017)Fumigation is an important crop protection practice employed to control soil pathogens and diseases. Metham sodium and cadusafos are two commonly used soil fumigants for this purpose. However, little information is available ... -
Ecotoxicological effects of aflatoxins on earthworms under different temperature and moisture conditions
Fouché, Tanya; Claassens, Sarina; Maboeta, Mark Steve (MDPI AG, 2022)Aflatoxin contamination remains one of the most important threats to food safety and human health. Aflatoxins are mainly found in soil, decaying plant material and food storage systems and are particularly abundant during ... -
