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:Ndlela, Luyanda L; Oberholster, Paul J; Van Wyk, JohannesDate:Aug 2017With the effects of climate change, harmful algal blooms (HABs) have become a global concern, with serious implications in water scarce countries and vulnerable continents such as Africa. A need exists for low-cost, environmentally feasible ...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:Lemley, DA; Lamberth, SJ; Manuel, W; Nunes, M; Rishworth, GM; Van Niekerk, Lara; Adams, JBDate:Jun 2021Increased nutrient loading associated with rapid population growth is the leading cause of deteriorating water quality in urbanized estuaries globally. Small estuaries are particularly sensitive to changes when connection with the marine ...Read more
Author:Smith, Marie EDate:Jul 2022The southern Benguela is divided into the West Coast and the South-West Coast regions owing to a change in coastline orientation at Cape Point. These biogeographic regions are reflected in both the make-up and frequency of phytoplankton blooms. ...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:Robertson, Lain, L; Bernard, S; Smith, Marie EDate:Jan 2021Harmful algal blooms (HABs) occur in virtually all coastal regions of the world as well as many lakes, and are typically associated with a rapid proliferation of phytoplankton cells, but even low cell numbers of high toxic species may cause ...Read more
Author:Bernard, Stewart; Pitcher, G; Evers-King, H; Robertson, L; Matthews, M; Rabagliati, A; Balt, CDate:2014The Benguela, as a highly productive upwelling system, suffers from the occurrence of a variety of harmful algal blooms, most of which are associated with elevated biomass; a feature common to the shelf environment of upwelling systems. Most ...Read more
Author:Smith, Marie EDate:Nov 2022Relatively young industry with potential for growth. Together, the Aquaculture and Fisheries sector could contribute approximately R10-15 Billion to SA’s GDP.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
Author:Bernard, Stewart; Kudela, RM; Franks, P; Fennel, W; Kemp, A; Fawcett, A; Pitcher, GCDate:2006The Benguela system suffers from the frequent occurence of a variety of harmful algal blooms (HABs).These blooms can have severe negative impacts on local marine ecosystems and communities, in addition to commercial marine concerns such as ...Read more
Author:Smith, Marie E; Bernard, StewartDate:Feb 2020The aquaculture industry of southern Africa faces environmental threats from harmful algal blooms (HABs), which have the potential to cause devastating economic losses (Pitcher et al., 2019).
