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 ... -
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 ...
