    Taxonomy, distribution and toxicity of dinoflagellate species in the southern Benguela current, South Africa
    (2003) Botes, Lizeth; Hedderson, Terry A; Cook, Peter A; Pitcher, Grant C
    The threat of harmful algal blooms with their attendant problems, exists throughout the Benguela region. In the southern Benguela upwelling system, water discolorations, referred to as 'red tides', are common and usually attributed to dinoflagellate species. The first aim of the thesis was to investigate the taxonomy of gymnodinioid species in the southern Benguela current. In order to investigate the morphology of the southern Benguela isolates, a simple and rapid scanning electron microscope preparative technique was developed. In the course of these studies, a new genus and new species were identified and described.
