A genetic geomorphic classification system for Southern African palustrine wetlands: Global implications for the management of wetlands in drylands
(Frontiers, 2019)
Due to climatic constraints in dryland regions, wetlands usually occur at confluences
of flow paths, whether from surface flow, inter-flow or at locations of groundwater
discharge. Long-term landscape processes that shape ...
Understanding seasonal dynamics of invasive water hyacinth (eichhornia crassipes) in the greater letaba river system using sentinel-2 satellite data
(Taylor & Francis Online, 2019)
Water hyacinth (Eichhornia crassipes) is one of the most aggressive and lethal free-floating aquatic weed that degrades and chokes freshwater ecosystems and threatens aquatic life. Early detection and up-to-date information ...
Remotely sensed c3 and c4 grass species aboveground biomass variability in response to seasonal climate and topography
(Wiley Online Library, 2019)
Seasonal climate and topography influence C3 and C4 grass species aboveground biomass (AGB). Climate change further threatens these grasses AGB, thereby compromising their ability to provide ecosystem goods and services. ...
Investigating changes over time of annual rainfall in Zimbabwe
(Copernicus Publications, 2010)
There is increasing concern in southern Africa
about the possible decline of rainfall as a result of global
warming. Some studies concluded that average rainfall in
Zimbabwe had declined by 10% or 100 mm during the ...
Influence of termites on the soil seed bank in an African savannah
(Wiley, 2018)
In savannah ecosystems, termites drive key ecosystem processes, such as primary
production through creation of patchiness in soil nutrients availability around their
nests. In this study, we evaluated the role of termites ...
Will a rising sea sink some estuarine wetland ecosystems?
(Elsevier, 2016)
Sea-level rise associated with climate change presents a major challenge to plant diversity and ecosystem service
provision in coastal wetlands. In this study, we investigate the effect of sea-level rise on benthos, ...
A conceptual model for the development and management of the Cape Flats aquifer, South Africa
(Water Research Commission, 2010)
This paper provides an integrated approach to the analysis of the geological, hydrological and hydrogeological characteristics
of the Cape Flats: a coastal plain sand formed within the mountains of the Cape Town metropolitan ...
Modelling the distribution of the invasive Ziziphus mauritiana along road corridors in Zimbabwe
(Wiley, 2019)
We investigate how human fruit consumption affects the spread of the alien invasive
Ziziphus mauritiana along road corridors in northern Zimbabwe. A field survey was
conducted to identify and map Z. Mauritiana stems at ...
