Assessing predator-prey interactions in a chemically altered aquatic environment: the effects of DDT on Xenopus laevis and Culex sp. larvae interactions and behaviour
(Springer, 2019)
Behavioural assays are used as a tool to understand ecotoxicological effects on organisms, but are often not applied in an ecologically relevant context. Assessment of the effect of chemical contaminants on behaviours ...
PCR amplification and DNA sequence of mcyA gene: the distribution profile of a toxigenic microcystis aeruginosa in the Hartbeespoort Dam, South Africa
(IWA Publishing, 2013)
Using new polymerase chain reaction (PCR) primers, a once known to be under-transcribed microcystin synthetase A (mcyA) gene from the only known toxigenic cyanobacterium Microcystis aeruginosa dominating the Hartbeespoort ...
The contribution of physical and chemical sediment characteristics to environmental risk from an irrigation scheme in South Africa
(Springer, 2015)
Purpose: The physical and chemical characteristics of sediment
from a South African irrigation scheme were used to
determine the sediment stressors within the system and to
determine whether or not stressors have the ...
Prioritizing agricultural pesticides used in South Africa based on their environmental mobility and potential human health effects
(Elsevier, 2014)
South Africa is the largest user of pesticides in sub-Saharan Africa and many studies have highlighted the occurrence of pesticides in water resources. Poor management of water treatment facilities in combination with a ...
The effect of acid mine drainage on the hatching success of branchiopod egg banks from endorheic wetlands in South Africa
(Springer, 2014)
Endorheic wetlands are abundant in South Africa, and are more commonly referred to as pans. The pan environment experiences daily and seasonal fluctuations in physico-chemical conditions, caused by variable hydroperiods. ...
Metal enrichment and contamination in a karst cave associated with anthropogenic activities in the Witwatersrand Basin, South Africa
(Springer, 2016)
The Wonderfontein Spruit has been severely polluted as a result of anthropogenic activities (i.e. mining and industry) in the Witwatersrand Basin (South Africa). Although the extent of metal pollution within this surface ...
Harnessing the rivers of knowledge for socio-economic development, climate adaptation & environmental sustainability
(Elsevier, 2012)
This Special Issue of Physics and Chemistry of the Earth presents
33 papers drawn from the 12th WaterNet/WARFSA/GWP-SA annual
symposium held in Maputo, Mozambique between 26 and
28 October 2011. It is the 11th special ...
Application of a Sediment Quality Index for the assessment and monitoring of metals and organochlorines in a premier conservation area
(Springer, 2015)
The physical and chemical characteristics of surface
sediments from a leading conservation area, namely the
Kruger National Park, were determined in order to identify
potential stressors in the systems that may contribute ...
Response of zooplankton communities to altered water quality and seasonal flow changes in selected river dominated estuaries in KwaZulu-Natal, South Africa
(Elsevier, 2019)
Globally, estuaries are among the most productive ecosystems with many threatened by anthropogenic activities. Zooplankton is a bioindicator of ecosystem integrity. The spatial and temporal composition of zooplankton ...
The role of fish helminth parasites in monitoring metal pollution in aquatic ecosystems: a case study in the world's most productive platinum mining region
(Springer, 2020)
Due to the increasing consumption of platinum (Pt), especially in automobile exhaust catalysts, environmental concentrations of Pt are of emerging concern worldwide. Limited information exists on environmental concentrations, ...
