Assessment of phytobenthos in the lower Phongolo River catchment in relation to changing environmental conditions
(North-West University (South Africa), 2020)Floodplain ecosystems are important since they provide numerous services and resources, including food, wood and water to humans. The lower Phongolo River floodplain is one such ecosystem and is the most unique and diverse ... -
Diatom diversity and response to water quality within the Makuleke Wetlands and Lake Sibaya
(North-West University (South Africa), Potchefstroom Campus, 2017)All forms of life are dependent on water for survival. South Africa is a water scare country, due to seasonal rainfall and high temperatures, thus it is important to manage water resources in such a way that it benefits ... -
Diatom teratologies as biomarkers of contamination: are all deformities ecologically meaningful?
(Elsevier, 2017)Contaminant-related stress on aquatic biota is difficult to assess when lethal impacts are not observed. Diatoms, by displaying deformities (teratologies) in their valves, have the potential to reflect sub-lethal responses ... -
Diatoms as indicators of historical water quality: a comparison of samples taken in the Wemmershoek catchment (Western Province, South Africa) in 1960 and 2008
(WRC (Water Research Commission), 2014)Historical diatom records provide a means of retrospectively determining water quality and inferring ecological condition in rivers and streams. In this study we re-sampled sites originally sampled 48 years previously. We ... -
Diatoms as indicators of water quality change from drought to flood conditions in the Kruger National Park
(North-West University (South Africa), 2023)Water as a resource is important for all living organisms and forms the very basis of life. The transportation of water, around the globe, forms the hydrologic cycle. This cycle includes precipitation, evaporation, and ... -
The diatoms of the Western Cape and their use in monitoring wetland water quality
(North-West University (South Africa), 2016)South Africa’s water resources are limited and, in global terms, scarce. The demand for water is, however, growing continuously due to population growth, a developing economy, global warming, the spreading of alien plant ... -
Diploneis fenestrata sp. nov. (Bacillariophyta), a new aerophilic diatom species from Zambia, Africa
(Magnolia Press, 2014)Diploneis fenestrata, a new aerophilic diatom is described from Lumangwe falls, Zambia. This novel species occurs as an epiphyte on the roots and stems of trees located within the spray zone of the falls. Its morphology ... -
The effect of illegal dumping on surface water quality using diatoms as a bioindicator
(North-West University (South Africa), 2021)Aquatic ecosystems are vital for all life on earth as, without water, there would be no life. It is therefore important that this vital resource is protected, properly managed and that all measures are taken to ensure ... -
Evaluation of the applicability of diatom based indices as bioindicators of water quality in South African rivers
(North-West University, 2008)Diatoms have been proven to be reliable indicators of water quality in many countries of the world particularly Europe. The potential use of diatoms as indicators of water quality in South Africa was tested in the studies ... -
Navicula nielsfogedii J.C. Taylor & Cocquyt sp. nov., a new diatom (Bacillariophyta) from tropical and sub-tropical Africa
(Czech Phycological Society, 2016)In this paper we describe Navicula nielsfogedii sp. nov., a commonly occurring diatom through central and southern Africa and distributed from the sub-tropical zones of South Africa to tropical central Africa. We have ...
