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 ...
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 ...
Perfluorinated compounds in the aquatic food chains of two subtropical estuaries
(Elsevier, 2019)
Per- and polyfluoroalkyl substances (PFASs) are ubiquitous in the environment and remain in largely unknown concentrations and with unknown effects on the African continent. Here we aimed to assess the presence of 15 PFASs ...
South Africa
(Academic Press, 2019)
South Africa has the second longest coastline on the African continent and spans two oceans. The confluence of the Benguela and Agulhas Currents off South Africa results in their dynamics being complex and often unpredictable, ...
Lateral hydrological connectivity differentially affects the community characteristics of multiple groups of aquatic invertebrates in tropical wetland pans in South Africa
(Wiley, 2019)
River–floodplain connectivity (i.e. lateral hydrological connectivity, LHC) can directly affect the community characteristics by promoting dispersal of organisms but can also have profound indirect effects by altering local ...
How toxic is a non-toxic nanomaterial: behaviour as an indicator of effect in Danio rerio exposed to nanogold
(Elsevier, 2019)
Gold nanoparticles are used as drug delivery vectors based on the assumption that they have low toxicity. Literature has, however, produced conflicting results over the last few years. As such, this study aimed to investigate ...
Bioaccumulation and trophic transfer of total mercury in the subtropical Olifants River Basin, South Africa
(Elsevier, 2019)
The present study describes total mercury (THg) levels in surface water, sediment and biota from the Olifants River Basin (ORB) (South Africa) and investigates the trophic transfer of THg by means of trophic magnification ...
Bioaccumulation and metal-associated biomarker responses in a freshwater mussel, Dreissena polymorpha, following short-term platinum exposure
(Elsevier, 2019)
Due to the increasing presence of platinum (Pt) in the environment, the caveat arises to identify its toxic potential in species at risk of being exposed – especially those found in aquatic environments where pollutants ...
Dichlorodiphenyltrichloroethane (DDT) levels in rat livers collected from a malaria vector control region
(Japanese Society of Veterinary Science, 2019)
Dichlorodiphenyltrichloroethane (DDT) is an organochlorine insecticide that has
been used for indoor residual spraying for the control of mosquito-borne diseases including
malaria. However, due to its toxicity and ...
