Concentrations and compositions of metallic elements in commercially important marine species
(North-West University (South Africa), 2020)Metals have been in our environment since the genesis of the world and are ubiquitous in all environments. We as humans mine, utilize, and release these metals from the environment to a level that may affect chronically ... -
Cross-species analyses of intra-species behavioral differences in mammals and fish
(Elsevier, 2020)Multiple species display robust behavioral variance among individuals due to different genetic, genomic, epigenetic, neuroplasticity and environmental factors. Behavioral individuality has been extensively studied in various ... -
Determination of antibiotic residues in fish sold in the supermarkets around Mafikeng, North West Province
(North-West University (South Africa), 2019)Aquaculture production has grown in the past decade, leading to a concurrent substantial growth in the use of antibiotics by the industry. The primary aim of this study was to determine antimicrobial residue levels of ... -
Effects of an antidepressant mixture on the brain serotonin and predation behavior of hybrid striped bass
(Wiley, 2016)Antidepressants have been found in measurable concentrations in final treated wastewater effluent and receiving waters throughout the world. Studies have shown that these concentrations are typically not overtly toxic, but ... -
Novel information on the morphology, phylogeny and distribution of camallanid nematodes from marine and freshwater hosts in South Africa, including the description of Camallanus sodwanaensis n. sp.
(Elsevier, 2019)Four species of previously known nematodes from the family Camallanidae were found from different hosts in South Africa: Batrachocamallanus xenopodis from the frog Xenopus muelleri, Paracamallanus cyathopharynx and ... -
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 ... -
Pollutants in marine biota from three Mascarene islands
(North-West University (South Africa), 2020)The Indian Ocean is the third-largest body of water on the planet. It is a source of food and livelihood for millions of people—most of them from developing countries. The western Indian Ocean (WIO) extends from the shores ... -
Presence, levels and distribution of pollutants in the estuarine food web : Swartkops River Estuary, South Africa
(North-West University, 2014)Estuaries are among the most productive and diverse of aquatic habitats supporting a rich variety of plants and animals. They are nursery areas for many species of fish harvested by recreational and subsistence anglers. ... -
Sources, pathways, exposures and hazards of perfluorinated chemicals in the Orange River Catchment
(North-West University (South Africa), Potchefstroom Campus, 2017)Persistent organic pollutants (POPs) can be classified as widely distributed organic compounds, sharing a suite of physical and chemical properties, occurring in all environmental compartments with serious toxicological ... -
The effects of bupropion on hybrid striped bass brain chemistry and predatory behavior
(Wiley, 2016)Increased use of antidepressants has led to an increase in their detection in final treated wastewater effluents and receiving streams. Antidepressants are intended to modify human behavior by altering brain chemistry, and ...
