Chemical cue interactions between alien invasive and native aquatic gastropods in the iSimangaliso Wetland Park, South Africa.
(2013)The importance of chemical cues in mediating interactions among individuals and structuring communities is being increasingly recognized in aquatic environments. Chemical cues have been shown to drive predator-prey ... -
The commercial and recreational marine skiboat linefisheries in Richards Bay, KwaZulu-Natal.
(2005)In order to assess and improve their management, a survey of the commercial and recreational marine linefisheries in Richards Bay was conducted from June 2002 to July 2004. The ultimate aim of this survey was to develop a ... -
Community dynamics of meiofauna during a wet phase in the St Lucia estuarine system, South Africa.
(2015)Meiofauna are an important component within the benthic environment of any aquatic habitat. Despite their significance and ubiquitous nature, these organisms are relatively poorly studied in Africa. Following a decade long ... -
Community structure and function of macrobenthos in three feature areas of the Natal Bight, South Africa.
(2013)The Natal Bight off the east coast of South Africa is a unique shelf habitat, exhibiting high secondary productivity and supporting high diversity. Ecosystem attributes are influenced by local oceanographic features and ... -
Coral propagation for aquarium specimens.
(2001)Coral reefs are being destroyed and degraded by natural and anthropogenic processes. Live corals are becoming increasingly popular as marine aquarium specimens, in both the commercial and private sectors, leading to the ... -
Coral recruitment on a high-latitude reef at Sodwana Bay, South Africa : research methods and dynamics.
(2011)Coral recruitment is a key process that contributes to the community structure and resilience of coral reefs. As such, quantification of this process is important to assist with the management of these threatened ecosystems. ... -
Dietary dynamics of two key fish species in the St Lucia estuarine system, South Africa.
(2014)Among the 155 species of fish recorded so far in the St Lucia estuarine lake, Oreochromis mossambicus and Ambassis ambassis are the two most prominent. Although originally endemic to southern Africa, O. mossambicus is ... -
Diversity and distribution of subtidal soft-bottom macrofauna of the Isimangaliso Wetland Park, South Africa.
(2014)There have been no previous studies describing the subtidal soft-bottom macrofaunal assemblages of the iSimangaliso Wetland Park or how they are influenced by the ecological and environmental processes associated with coral ... -
The dynamics of microphytobenthos in the Mdloti and Mhlanga estuaries, Kwazulu-Natal.
(2004)Microphytobenthos (MPB) generally dominates total autotrophic biomass in temporarily open/closed estuaries (TOCEs) of South Africa. A comparative study of MPB biomass was undertaken in two KwaZulu-Natal TOCEs, the Mdloti ... -
The dynamics of nano- and microplankton in the St. Lucia estuarine lake system, KwaZulu-Natal.
(2013)St. Lucia estuarine lake system has a history of episodic droughts and floods leading to a high variability in physico-chemical characteristics which may influence the community structure of nano- and microplankton ... -
Ecophysiology of intertidal corals along the east coast of South Africa : coping in marginal habitats.
(2014)Coral survival in a time of climate change will depend largely on the ability to tolerate, acclimatise and adapt to changes in their natural environment. High-latitude intertidal corals along the east coast of South ... -
Ecosystem functioning of selected estuaries on the east coast of South Africa.
(2013)River inflow is one of the most important factors influencing the density and biomass of estuarine biotic communities. The aim of this study was to obtain an understanding of the ecosystem functioning of selected estuaries ... -
Evaluating the thermal stress response of South African abalone, Haliotis midae, to biogeographical temperature variability.
(2014)A gradient of sea temperatures is created along the South African coastline by the confluence of the cold Benguela Current on the West coast with the warm Agulhas Current on the East coast. This temperature gradient allows ... -
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 ...
