Changes in mangroves at their southernmost African distribution limit
(Elsevier, 2020)
Mangroves in South Africa occur at one of the most southerly locations in the world, which provides a unique opportunity to study their dynamic responses to anthropogenic and natural perturbations. The exposed high-energy ...
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 ...
A novel approach to quantify metrics of upwelling intensity, frequency, and duration
(Public Library of Science, 2021)
The importance of coastal upwelling systems is widely recognized. However, several
aspects of the current and future behaviors of these systems remain uncertain. Fluctuations
in temperature because of anthropogenic climate ...
Indigenous African cereal crops can contribute to mitigation of the impact of climate change on food security
(Arid land institute, 2021)
Zea mays L. (maize) is one of the top three cultivated cereals globally, along with
wheat and rice. The United States, China, and Brazil are among the largest
producers of maize, producing approximately 79% of the world’s ...
Too hot to nest? In a hot summer the Tortoise Chersina Angulata can switch from nesting to facultative viviparity
(Frontiers Media, 2022)
In a captive colony of Chersina angulata in Cape Town, South Africa, we observed
in 2015/16 retention of the last egg clutch inside the female until the hatching stage
was reached, conforming to the generally accepted ...
Current status of fuel cell based combined heat and power systems forresidential sector
(Elsevier, 2015)
Combined Heat and Power (CHP) is the sequential or simultaneous generation of multiple forms of usefulenergy, usually electrical and thermal, in a single and integrated system. Implementing CHP systems inthe current energy ...
GIS-based modelling of climate variability impacts on groundwater quality: Cape Flats aquifer, Cape Town, South Africa
(Elsevier, 2021)
The need to improve groundwater security remains critical, especially in urban areas where demand for groundwater as an alternative source of water supply is increasing following unprecedented population growth. Climate ...
Modeling the geographic spread and proliferation of invasive alien plants (IAPs) into new ecosystems using multi-source data and multiple predictive models in the Heuningnes catchment, South Africa
(Taylor and Francis, 2021)
The geographic spread and proliferation of Invasive Alien Plants (IAPs) into new ecosystems
requires accurate, constant, and frequent monitoring particularly under the changing climate to
ensure the integrity and resilience ...
Effect of landscape pattern and spatial configuration of vegetation patches on urban warming and cooling in Harare metropolitan city, Zimbabwe
(Bellweather Publishing, 2021)
The spatial configuration of vegetation patches in the landscape has implications for the provision of ecosystem services, human adaptation to climate change, enhancement, or mitigation of urban heat island. Until recently, ...
