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 ... -
Spatio-temporal variations of the sedimentology and geochemistry of six estuaries within the eThekwini Municipality, KwaZulu-Natal, South Africa.
(2014)Estuaries are dynamic features of a coastline whose sediments are influenced by riverine and marine processes. Periodic events such as floods, as well as variations in mouth status, greatly affect the energy levels within ... -
The status of the riverbream Acanthopagrus berda (Sparidae) in estuarine systems of northern KwaZulu-Natal, South Africa.
(2001)Acanthopagrus berda is an estuarine-dependent fish species which is widespread in the tropical Indo-Pacific. In South Africa, it is particularly abundant in the three large northern KwaZulu-Natal estuarine systems, namely ... -
Transboundary water resource management of the Pongolo River/Rio Maputo.
(2002)In the Twenty-first Century, sustainable water management is likely to be humanity's greatest challenge in a world of ever-increasing demand. Legal instruments both international and national regulate and provide a general ... -
The vegetation ecology of the lower Mkuze river floodplain, Northern KwaZulu-Natal : a landscape ecology perspective.
(2001)The overall aim of this study was to develop an understanding of the vegetation ecology of the lower Mkuze River floodplain from a landscape ecology perspective. The lower Mkuze River floodplain and its associated wetlands ... -
The zooplankton of temporarily open/closed estuaries : case studies of the Mdloti and the Mhlanga estuaries, KwaZulu-Natal North Coast.
(2005)The zooplankton communities of the Mdloti and Mhlanga estuaries were studied over a 13-month period (March 2002-March 2003). Monthly daytime samples were collected from both estuaries at the lower, middle and upper reaches ...
