Author:Smith, Marie E; Vhengani, Lufuno MDate:May 2023This presentation speaks to the challenges with environmental threats such as Harmful Algal Blooms (HABs) and ocean heatwaves that have the potential to negatively affect natural and farmed marine resources. Also, monitoring these events ...Read more
Author:Ndlela, Luyanda L; Oberholster, Paul J; Van Wyk, JH; Cheng, Po Hsun HDate:Dec 2018Biological control of cyanobacteria is a well-researched area with a central focus on laboratory-scale studies. Numerous reports have been made on algicidal isolates, with bacteria as a major component of the antagonists. The research in this ...Read more
Author:Joyce, LB; Pitcher, GC; Du Randt, A; Monteiro, Pedro MSDate:Feb 2005The distribution and abundance of dinoflagellate cysts from recent coastal sediments in Saldanha Bay, was investigated, and compared to the cyst assemblages of the adjacent coastal upwelling system as reflected in the sediments of Lambert's ...Read more
Author:Matthews, MW; Bernard, Stewart; Evers-King, H; Robertson Lain, LDate:Oct 2020A hyperspectral inversion algorithm was used to distinguish between cyanobacteria and algal blooms in optically complex inland waters. A framework for the algorithm is presented that incorporates a bio-optical model, a solution for the radiative ...Read more

Author:Adams, JB; Taljaard, Susan; Van Niekerk, Lara; Lemley, DADate:Feb 2020Nutrient pollution in South African estuaries is described using a Driver-Pressure-State-Impact-Response framework. The root cause (‘driver’) of deteriorating water quality is rapid population growth that leads to increasing inputs from ...Read more
Author:Magonono, M; Oberholster, Paul J; Addmore, S; Stanley, M; Gumbo, JRDate:Jul 2018The presence of harmful algal blooms (HABs) and cyanotoxins in drinking water sources poses a great threat to human health. The current study employed molecular techniques to determine the occurrence of non-toxic and toxic cyanobacteria species ...Read more
