Genetic diversity of symbiodinium in selected corals in the Western Indian Ocean.
(2007)Coastal communities along the east African coastline rely on coral reefs and their associated resources for food security and income. However, increases in the frequency and severity of episodes of coral bleaching have ... -
Genetic population structure of deep-water prawns Haliporoides triarthrus and langoustines Metanephrops mozambicus in the South West Indian Ocean : use of mitochondrial DNA to investigate metapopulation structure.
(2013)Deep-water prawns Haliporoides triarthrus and langoustines Metanephrops mozambicus are endemic to the South West Indian Ocean (SWIO) region and make up the largest proportion of deep-water crustacean trawl catches in ... -
Impact of turbidity on pseudodiaptomus stuhlmanni, a dominant copepod in Lake St Lucia, iSimangaliso Wetland Park.
(2015)Although the St Lucia Estuary is a Ramsar Wetland of International Importance, it has historically been subjected to human-accelerated ecological stressors. One of these is high turbidity resulting from excessive sediment ... -
Influence of heterotrophic feeding on the sexual reproduction of Pocillopora verrucosa (Scleractinia, Pocilloporidae) in aquaria.
(2009)Corals are able to source autotrophically-produced carbon since they have symbiotic unicellular dinoflagellates embedded in their tissue. However, they are also known to be heterotrophic feeders and able to ingest a variety ... -
The influence of heterotrophy on the resilience of hard coral Pocillopora damicornis to thermal stress and bleaching.
(2013)Global warming from anthropogenic greenhouse gas emissions causes temperature increases in aquatic ecosystems. The rise in environmental temperatures places sensitive organisms under thermal stress. Reef-building corals ... -
An intergrated study of the eziMbokodweni estuary : water and sediment quality, and estuary-nearshore material fluxes.
(2013)This study represents an integrated and holistic assessment of the eziMbokodweni Estuary’s water and sediment quality. The estuary was once relatively un-impacted but now flows through a highly anthropogenically-modified ... -
An investigation of the population connectivity of sardines (Sardinops sagax) of the KZN sardine run using meristic, morphological and genetic data.
(2014)The Sardine run occurs annually when large schools of sardine (Sardinops sagax) move from the Agulhas Bank towards KwaZulu-Natal, and has significant ecological and anthropogenic importance. Recent investigation has ... -
The macrobenthos of the Little Lagoon, Durban Bay.
(2002)The Little Lagoon is a shallow sandflat habitat situated in Durban Bay, which has been earmarked for removal, as part of the port expansion. In order to prevent the possible loss of such a significant habitat, it was ... -
Macrobenthos used to validate multi-criteria derived marine biodiversity spatial zones in KwaZulu-Natal, South Africa.
(2017)Compared to terrestrial ecosystems, the characteristics of marine ecosystems remain largely under-explored. Marine and coastal ecosystems provide a number of ecological services and societal benefits (resources for commercial ... -
Management of the linefish resource in Southern Mozambique : a case study for Marreco (Chrysoblephus puniceus).
(2001)This study provides information on the biology, stock status and the management of C. puniceus, a key linefish resource in southern Mozambique. This is regionally endemic to Mozambique and KwaZulu-Natal. Fairly resident ... -
Marine nutrient dynamics of the KwaZulu-Natal bight : assessing bacterial numbers, biomass and productivity.
(2013)The KwaZulu‒Natal Bight is formed from a narrow indentation in the SE coast of South Africa with the waters within considered to be oligotrophic. These waters therefore depend on both allochthonous sources of nutrients ... -
Modelling streamflow and sediment yield on the lower Mgeni catchment.
(2001)This study involves the application of the ACRU Agrohydrological Model to a selected study catchment in the Lower Mgeni Catchment, and its discretized subcatchments, immediately downstream of the Inanda Dam. This study was ... -
Molecular phylogeny and population genetic structure of the shallow-water spiny lobster Panulirus homarus in the South West Indian Ocean region : implications for management.
(2013)The scalloped spiny lobster, Panulirus homarus has a subspecies trio that are widely distributed in shallow-water habitats in the South West Indian Ocean. Subspecies are defined by differences in colour and abdominal ... -
Molecular revision of Zoantharia (Anthozoa Hexacorallia) on the east coast of South Africa.
(2014)The order Zoantharia (Cnidaria: Anthozoa) is ubiquitous on the east coast of South Africa, and despite their widespread distribution they are poorly represented in literature. No molecular identification has been carried ... -
An overview of the status of aquaculture in the Western Indian Ocean Region : a review.
(2011)The aim of this review is to gave a detailed overview of the status of aquaculture in the Western Indian Ocean Region. Emphasis is based on the legislation, cultured species and candidate species for aquaculture. The review ... -
Phosphorus distribution among selected abiotic and biotic components of two KwaZulu-Natal estuaries, South Africa.
(2013)Phosphorus is an essential element since it controls primary productivity in aquatic ecosystems and its excess can lead to eutrophication in receiving systems. The aim of this project was to determine phosphorus distribution ... -
Post-Harvest seed physiology and conservation of the germplasm of syzgium cordatum hochst.
(2013)There is global concern about the ex situ conservation of the germplasm/genetic resources of recalcitrant-seeded species. While orthodox (desiccation tolerant) seeds afford an ideal means for ex situ conservation, this is ... -
Relationship between sediment structure and infaunal amphipod communities along the Durban outfalls region on the east coast of South Africa.
(2010)Increased human habitation brings associated pressures with it, such as the introduction of contaminants to coastal waters. The major sources of these occur along the KwaZulu-Natal coast via Sappi Saiccor discharge points, ... -
Responses of Avicennia marina (Forssk.) Vierh. to contamination by selected heavy metals.
(2008)Heavy metal contamination of mangroves is of critical concern due to its accumulative and adverse effects in aquatic ecosystems. This study was undertaken to investigate the effects of mercury (Hg ), lead (Pb ), copper (Cu ... -
A retrospective analysis of shark catches made by pelagic longliners off the east coast of South Africa and biology and life history of shortfin mako shark, Isurus oxyrinchus.
(2013)Oceanic pelagic shark species are under threat worldwide as fishing effort increases and they are taken as both targeted and bycatch. It is widely recognized that the life history characteristics of sharks make them ...
