Understanding the creek dynamics and environmental characteristics that determine the distribution of mangrove and salt marsh communities at Nahoon Estuary
(Elsevier, 2016)The southern distributional limit for mangroves on the east coast of Africa is thought to be at the planted mangrove forest at Nahoon Estuary (33° S) in the Eastern Cape, South Africa. This study investigated the influence of ... -
Unraveling the diversification and systematic puzzle of the highly polymorphic Psammobates tentorius (Bell, 1828) complex (Reptilia: Testudinidae) through phylogenetic analyses and species delimitation approaches
(Wiley-Blackwell, 2020)The high level of phenotypic diversity in southern African tent tortoises (Psammobates tentorius complex) has for decades prevented systematists from developing a stable taxonomy for the group. Here, we used a comprehensive ... -
Using a multiple-delivery-mode training approach to develop local capacity and infrastructure for advanced bioinformatics in Africa
(Public Library of Science, 2021)With more microbiome studies being conducted by African-based research groups, there is an increasing demand for knowledge and skills in the design and analysis of microbiome studies and data. However, high-quality ... -
Variation and change of upwelling dynamics detected in the world's eastern boundary upwelling systems
(Frontiers Media, 2021)Global increases in temperature are altering land-sea temperature gradients. Bakun (1990) hypothesized that changes within these gradients will directly affect atmospheric pressure cells associated with the development of ... -
Variation and change of upwelling dynamics detected in the world’s eastern boundary upwelling systems
(Frontiers Media S.A., 2021)Global increases in temperature are altering land-sea temperature gradients. Bakun (1990) hypothesized that changes within these gradients will directly affect atmospheric pressure cells associated with the development of ... -
Variation in the daily activity, movement and refugia of Critically Endangered geometric tortoises, Psammobates geometricus, in autumn and spring
(Taylor & Francis, 2017)To help assess habitat requirements of Critically Endangered geometric tortoises, we used thread-trailing to measure daily activity, movements and refugia of adult Psammobates geometricus in autumn and spring 2002. We found ... -
Video observations on the habitat association of demersal nekton in the mid-shelf benthic environment off the Orange River mouth
(NISC and Taylor & Francis, 2000)A semi-quantitative assessment is made of the animals observed in archived videotapes taken from the research submersible Jago, during diamond mining and exploratory surveys off the mouth of the Orange River on the west ... -
West Coast plants for a waterwise garden
(Botanical Society of South Africa, 2009)The new gardening mantra is 'grow indigenous'. Besides their aesthetic value, most indigenous plants are less costly to maintain, largely because they have long adapted to the local climate and thus to the local rainfall. ... -
Wildlife- friendly livestock management promotes mammalian biodiversity recovery on a semi-arid Karoo farm in South Africa
(Frontiers Media, 2021)Agriculture is an essential production system used to feed the growing human population, but at the same time has become a major driver of biodiversity loss and environmental degradation. Employing production methods that ... -
Will climate warming exceed lethal photosynthetic temperature thresholds of lichens in a southern African arid region?
(Wiley, 2013)Predicted elevated temperatures and a shift from a winter to summer rainfall pattern associated with global warming could result in the exposure of hydrated lichens during summer to more numerous temperature extremes that ... -
Winter is coming: A southern hemisphere perspective of the environmental drivers of sars-cov-2 and the potential seasonality of covid-19
(MPDI, 2020)SARS-CoV-2 virus infections in humans were first reported in December 2019, the boreal winter. The resulting COVID-19 pandemic was declared by the WHO in March 2020. By July 2020, COVID-19 was present in 213 countries and ... -
Wound healing activities and potential of selected african medicinal plants and their synthesized biogenic nanoparticles
(2021-11)In Africa, medicinal plants have been traditionally used as a source of medicine for centuries. To date, African medicinal plants continue to play a significant role in the treatment of wounds. Chronic wounds are associated ... -
Yeast supplementation alleviates the negative effects of greywater irrigation on lettuce and maize
(South African Water Research Commission, 2022)Water scarcity has led to increased use of wastewater, particularly greywater, for crop irrigation. This study investigated whether the addition of yeast can alleviate the potential negative effects of greywater use on ... -
You use seaweeds for that?
(Botanical Society of South Africa, 2006)Introduction: The word seaweed is commonly used, yet to refer to these marine algae as 'weeds' is very far from the truth. Together with microscopic algae called phytoplankton and other photosynthetic organisms, seaweeds ...
