Microplastic concentrations on the urban coastline of KwaZulu–Natal, South Africa, and its impact on juvenile fish.
(2018)The global production of plastics per annum has increased from 1.5 million tonnes in the 1950‘s to 300 million tonnes today. Following this increasing production trend, plastic concentrations have increased over time in ... -
The fertilisation and recruitment dynamics of scleractinian corals on South Africa's high-latitude reefs.
(2018)2 The production of coral offspring and their survival through early ontogeny to sexual maturity 3 are both vitally important for the persistence of coral-dominated reefs. Understanding factors 4 which affect these ... -
Ciliate-zooplankton epibiosis in Lake St Lucia.
(2018)Epibiosis is a symbiotic association of two organisms in which one species (epibiont) uses the surface of another species (basibiont or host) as an attachment substrate. An increasing number of studies are revealing that ... -
An assessment of the effectiveness of the St. Lucia marine reserve (KwaZulu-Natal, South Africa) in the protection of surf-zone angling fish species.

Development of a sediment toxicity test for the South African coastal environment using the endemic amphipod, Grandidierella lignorum Barnard 1935 (Amphipoda: Aoridae).
(2013)Contaminants introduced in solution to coastal waters eventually accumulate in sediment. Pollution by these contaminants is only evident when biological effects occur. Geochemical procedures lack the ability to identify ... -
Ecological genetic connectivity between and within southeast African marginal coral reefs.
(2014)Marine protected areas (MPAs) have been established along the East African coast to protect coral communities from human and natural disturbance. Their success is dependent on the degree to which resource populations are ... -
Diversity of bivalve molluscs within the St Lucia estuarine system, with emphasis on the ecophysiology of Solen cylindraceus and Brachidontes virgiliae.
(2014)The St Lucia estuarine system, Africa’s largest estuarine lake, is characterised by cyclic changes from hypersaline to oligo/mesohaline conditions in response to alternations between drought and wetter than average years. ... -
Mark-recapture models for determination of mortality, migration and growth in Pomatomus saltatrix (Teleostei)
(1996)This study primarily attempts to develop models to estimate population dynamic parameters from mark-recapture data. Model implementation is illustrated using data collected from the South African Pomatomus saltatrix fishery ... -
Zooplankton dynamics and ecophysiology in the St. Lucia Estuary, with emphasis on the dominant mysid Mesopodopsis africana.
(2011)The St. Lucia Estuary, Africa’s largest estuarine lake, is currently experiencing an unprecedented crisis related to freshwater deprivation. This has resulted in a reversed salinity gradient and drastically reduced water ... -
An evaluation of coral reef fish communities in South African marine protected areas.
(2010)Differences in coral reef fish assemblages were investigated on six South African and one southern Mozambican reef under varying management regimes. All of the South African reefs fall within marine protected areas (MPA) ... -
Comparative life histories and stock assessments of rockcods (family Serranidae) from the east coast of South Africa.
(2000)The family Serranidae is a diverse group of fishes, of which the genus Epinephelus (rockcods or groupers) is the largest. Serranids are commonly caught in reef fisheries in tropical and warm-temperate latitudes, and are ...
